PGD (Pre-implantation Genetic Diagnostic)
PREIMPLANTATION GENETIC DIAGNOSIS
In recent years, developments in genetics allow genetic analysis to be carried out on embryos developed in vitro by in vitro fertilization ethods and the placement of selected healthy embryos in the uterus of the mother before pregnancy occurs. This method is called pre- regnancy genetic diagnosis (Preimplantation Genetic Diagnosis-PGD).
One of the most important application areas of the PGT technique embryos that do not have a genetic disease but may not have a genetic disorder in their chromosomes.
These disorders are more common in women of advanced age (35 years and older). This situation may result in infertility as it both reduces the chance of attachment of the embryo (implantation) and may cause unwanted abortions. As a matter of fact, 40 out of every 100 pregnancies in women aged 39 and over have problems that occur due to a numerical chromosomal disorder
The aim of PGD is to increase implantation rates, reduce spontaneous abortions and increase healthy baby birth rates by selecting hromosomally normal embryos. Indeed, the miscarriage rate, which can reach up to 23 percent in normal pregnancy due to chromosomal disorders, may decrease to 9 percent after PGD.
Pre-pregnancy genetic diagnosis is performed by taking 1 or 2 cells from embryos developed as a result of fertilization of egg and sperm cells obtained from mother and father candidates in laboratory environment. Special methods called Fluorescence In Situ Hybridization (FISH), Microarray-based comparative genomic hybridization (aCGH) or Polymerase Chain Reaction (PCR) are used for genetic diagnosis. Diagnosis of numerical chromosomal disorders such as monosomy or trisomy (Down syndrome and other trisomies) and single gene diseases (such as hemophilia, Mediterranean anemia, cystic fibrosis, muscular dystrophies) in the baby to be born is possible with PGD. Thus, healthy babies are born by transferring disease-free, healthy embryos to the expectant mother.
DIAGNOSIS BEFORE PREGNANCY
- In couples with a genetic or hereditary disease carrier,
- In couples who have a child or children with a previous genetic disease,
- For the purpose of HLA genotyping (tissue typing),
- In the identification of diseases showing genetic predisposition (tendency)
- Women in the advanced age group (37 years and over) who have been accepted for assisted reproductive techniques,
- In couples with recurrent early pregnancy miscarriages,
- In couples who could not achieve pregnancy with assisted reproductive techniques despite multiple applications or who lost their pregnancy due to miscarriage,
- It is applied in cases of chromosomal disorders or genetic diseases associated with severe male infertility.
HOW IS THE PGT TEST DONE?
- Whether the patient is suitable for PGD is evaluated by the reproductive health specialist, genetic counselor and the doctor of the related disease.
- The couple is prepared for the IVF procedure.
- The egg taken from the mother is fertilized in the laboratory with the sperm taken from the father.
- 1-2 blastomere cells are removed from the obtained embryo by biopsy by embryologists
- Cells obtained by biopsy are prepared and tested according to the method to be applied.
- Embryos with genetic diseases or chromosomal disorders are selected and discarded and healthy embryos are transferred to the mothers womb.
Microchip
In patients with low sperm viability, quantity, number and structural quality, microfluidic technology, also known as the "chip baby method", ensures that the best quality sperm cells are selected by competing with each other in a way similar to the natural environment in the uterus, and ICSI is defined in in vitro fertilization treatment. With the application, it is left into the egg cell by microinjection method.
In this method, sperm cells with the best structural form, genetics and physiology are selected without causing cell damage, since techniques such as centrifugation (settling), vortex (mixing with high vibration) or mixing with a pipette are not applied to the sperm cells, which can physically damage the sperm cells. In classical preparation methods, sperm cells are prepared in a shorter time without being subjected to manipulation by skipping processes such as washing, flotation, gradient (grading), centrifugation (precipitation at high speeds). Thus, the sperm cells with the best DNA quality and physiologically are selected by themselves, and the sperm cells that pass this pre-screening are again screened under the microscope and the sperm cells of excellent quality are used for microinjection.
The above-mentioned classical preparation methods cause sperm cells to undergo respiratory stress, known as oxidative stress, and it has been scientifically proven that this can also cause DNA damage in healthy sperm cells. Better quality embryos are tried to be obtained with sperm cells that have been proven to be of the best quality by scientific data, and thus embryos with the highest potential for implantation (attachment) and development are obtained. The average total mobility in suckling samples taken from male individuals with microchip technology increased by 1.7 times.
The sperm cells obtained by this method were found 3 times faster than the classical preparation methods, and the forward motile sperm cells increased 3.8 times.
What Is insemination? How Is It Done?
There are 2 treatment methods most commonly preferred by couples who want to have a baby but do not have a baby for various reasons. One of them is in vitro fertilization treatment and the other is insemination method. In our article, we will try to answer the most frequently asked questions about the vaccination method, what is insemination and how it is done.
What is insemination?
If couples cannot get a pregnancy result after one year after unprotected sexual intercourse, infertility is diagnosed. Infertility can have many causes, depending on the woman and the man. Thanks to science and developing technology, there are now many treatment methods for infertility. One of these methods is the vaccination method. In its simplest form, the method of vaccination is to prepare the sperm in the laboratory and inoculate the woman's uterus at the time of ovulation to ensure fertilization. In order for the vaccination method to be performed, some tests must be done to make sure that there is no problem in the uterus of the expectant mother. In addition, at least one of the tubes of the expectant mother must be in working condition. The purpose of the vaccination method is to select the motile, normal sperm with a higher probability of fertilization and send them to the uterus of the expectant mother. Thus, it will be more likely to be fertilized with eggs and selected sperm supported by drugs or pills.
How is insemination done?
Before the insemination method, the development of the egg is supported with pills or low-dose injections given to the expectant mother. During this process, the egg is tracked. When the eggs mature and reach certain sizes, a cracking needle is given and the eggs are cracked. Just at this time of cracking, the sperm prepared in the laboratory are transferred to the uterus. Thus, the most suitable time of ovulation is provided for the woman and the best sperm are transferred to the uterus at the right time. insemination is a natural method. Only sperms that will increase the probability of fertilization are carefully selected. From the sperms taken from the father-to-be, those that are of good quality, motile and washed in a certain number, that is, processed. As Hüma IVF Center team, we tried to give information about what is insemination and how it is done in our article. We hope it was useful. You can contact us via our website to get more detailed information about IVF treatment or to ask your questions.
WHAT IS EMBRYO GLUE? HOW AND WHO USE IT? IS THE SUCCESS RATE HIGH?
As couples who want to become parents cannot become parents with natural methods, couples resort to some treatments. In vitro fertilization is the first treatment method. And IVF treatment is a very advanced and effective treatment method. Some applications in IVF treatment are important for the positive outcome of the treatment. Embryo glue application, which is one of the important application methods, is a very successful application. Embryo glue is one of the applications without any known risk. As a result of the studies, it was concluded that it did not increase the risk of miscarriage or pregnancy complications. Now we will provide you with detailed information about embryo glue. We wish you pleasant reading.
What is Embryo Adhesive?
Embryo glue, a method used in IVF treatments, is a kind of liquid embryo culture medium enriched with a substance called hyaluronan, in which embryos are left before transfer to the uterus of the expectant mother.
Hyaluronan is a natural carbohydrate found in all tissues in the body. The embryo needs an environment rich in carbohydrates, amino acids and protein in order to develop healthily inside. In addition, embryo glue is also called embryo glue because it reduces the ability of the embryo to move in the uterus.
How and Who Is Embryo Adhesive Used?
Embryo adhesive application is done as follows:
After the embryos are developed in the laboratory for 3-5 days, the most suitable one for embryo transfer is selected.
· The most suitable embryos selected for transfer are taken into the embryo glue.
· Embryos are kept in this environment for about 30 minutes.
· After standing, the embryos are taken from the culture dish and drawn into the catheter (a thin tube).
· The catheter is then passed through the cervix under ultrasound guidance and the embryos are transferred to the uterus.
In expectant mothers who have repeated in vitro fertilization failure using the embryo glue method,
It is used in couples who want to have children over the age of 35, when the quality of the embryo depending on the egg or sperm is not very good.
Is the Success Rate High in Embryo Bonding?
Embryo adhesive is one of the most frequently used applications for the last 10 years in order to increase the chance of success in IVF treatment. Experts were unsure about the effectiveness of embryo glue at first. However, in recent years, the effectiveness of embryo glue has been observed as a result of scientific research. Today, embryo glue is applied by various IVF centers. Hüma IVF Center is one of these centers.
The high concentration of hyaluronan concentrates the embryo glue similar to the tissue of the fluids in the womb, so that better mixing of these fluids minimizes the mobility of the embryo. In addition, hyaluronan acts as a bridge between the embryo and the inner wall of the uterus by binding to the inner wall of the uterus and the molecules on the surface of the embryo. In this way, it helps the embryo to attach to the uterus.
We aimed to give you information on this subject by considering the embryo glue method. We talked about how this method is applied and its success rate.
WHAT IS POLYCYSTIC OVER SYNDROME? WHAT ARE THE SYMPTOMS AND TREATMENT METHODS OF POLYCYSTIC OVER SYNDROME?
Polycystic ovary syndrome, which occurs due to irregular hormone production, is one of the most common hormonal disorders in women of reproductive age. Polycystic ovary syndrome, which is seen in one out of every 10 women, is manifested by menstrual irregularities such as abortion or long-term periods. So, what is polycystic ovary syndrome, the incidence of which has increased in recent years? What are the symptoms of polycystic ovary and treatment of polycystic ovary?
What is Polycystic Ovary Syndrome?
Follicles in different developmental stages in a normal ovary are selected during the menstrual period and become secondary and mature follicles. This selected follicle is then thrown out of the ovary with ovulation. In polycystic ovary syndrome, there are many immature follicles in the ovary and ovulation does not occur. Some changes are also seen in the hormone production of the ovary.

WHAT IS THE SPERMIOGRAM TEST FOR ANALYSIS OF SPERM CELL?
Parents who want to have children generally prefer the most common in vitro fertilization treatment. Before this treatment, both mother-to-be and father-to-be go through many tests. Father-to-be passed; The first of the tests to test for infertility or other problems is the sperm test, also known as the spermiogram test. What is the spermiogram test for the analysis of the sperm cell? How is spermiogram done? What do spermiogram test results mean? We will answer all these questions for you in detail below. We recommend that you continue reading our article to have detailed information about the sperm test.
What is a test (spermiogram)?
Sperm test done to men; It is a test to determine sperm health, sperm count, and whether the sperm are moving correctly in the channels. As a result of the sperm test, if the sperm shape is normal and there is a sufficient number of sperm, it is concluded that your reproductive ability is high. However, in some cases, men may have low sperm count or the ability to reproduce despite having abnormal semen. That's why doctors order a second test for the accuracy of the results. If your results are normal in your first sperm test, you give the other test and if it is normal, these two normal tests show that you do not have an infertility problem. If there are different conditions, your doctor may order other tests.
If there is no semen or sperm as a result of the sperm test, this may indicate that your ducts are blocked. If this is the case, your doctor will plan different surgeries to open the channels.
Issues and Precautions to Consider While Giving Sperm Sample
There are important points to be considered before giving the sperm sample and while giving the sperm sample. Among the things to be considered before giving a sperm sample, we can count that "men should abstain from sexual intercourse for 3 days". Fasting for 3 to 5 days is sufficient. These numbers are important because if you fast for less than 3 days, the sperm count may be low as a result of the sperm test. For this reason, we can say that fasting between 3 and 5 days is sufficient. It is possible to list the issues to be considered while giving a sperm sample as follows;
· Storing the sample in a sterile environment: It is important to protect your sample from the outside environment for a healthy and accurate spermiogram test result. If a sterile environment is not provided, the test result may be inaccurate. Therefore, do not put your hands, especially sample containers, etc. It is important that you keep it as sterile as possible.
· Protecting the delivered sperm from heat: Another important point is to keep your sample away from extreme temperature changes after ejaculation. Because these extreme temperature changes negatively affect spermatozoa. Ideal temperatures for the sample cup should be between 20°C and 37°C.
· Sperm volume, amount: Volume is extremely important in the sperm test. Your sperm volume is expected to be at least 1.5 ml. The reason why you cannot reach the lower limit of 1.5 ml may be external discharge during ejaculation. It is important to be careful about this.
· Use of lubricating foreign substances during the sperm test: It is important not to use any lubricant during the sperm test because these substances seriously affect the sperm parameters. External factors with such an impact can lead to wrong conclusions.
How is the Sperm Test Done?
For the sperm test, you must first be at the IVF center or hospital. There are rooms specially prepared for men in hospitals or IVF centers. In these rooms, men give their sperm in a special container. For the effectiveness of the sperm test, the sperm sample is immediately delivered to the laboratory. The sperm sample given in the laboratory is subjected to many processes and the best quality sperms are selected. The purpose of the procedures is to examine the sperm count, motility and shape in the semen and to reach quality sperm as a result.
Apart from the hospital, sperm samples can be placed in a container and brought to the hospital in the home environment. However, this is highly not recommended. Even if this is accepted, the sperm samples should be brought to the hospital and delivered within half an hour.

Issues and Precautions to Consider When Analyzing Sperm Sample
After the sperm test is given by the prospective fathers, it is examined in the laboratory environment. This examination takes approximately 1-2 hours and after the first hour, active results begin to be obtained. However, sometimes different situations can be encountered. For example, the test is given, but no sperm can be seen when looked at. In these cases, sperm are taken again and centrifuged. When faced with such a situation, the time may be extended. If there is no additional test to be done, the test results are immediately available in an average of 1-1.5 hours.
What Do Sperm Test Results Mean?
Sperm test results can be evaluated in many ways. Sperm analysis evaluates the sperm by analyzing it from various aspects. We can list these analyzes as follows:
· Sperm count and density:
Sperm count describes the number of sperm in 1 ml of semen. The World Health Organization advocates that a normal sperm count should be at least 15 million per ml or at least 39 million per sample. Having fewer sperm than these numbers indicates a low sperm count.
· Sperm morphology:
Non-abnormal sperm have a long tail and oval head. Morphology refers to the size and shape of the sperm a person has. Sperm that do not have a normal size or are weak in shape have difficulty reaching the egg and fertilization.
· Sperm motility:
The ability of sperm to move efficiently is one of the most important factors for fertilization.
· PH level of sperm:
When the pH level is too high or too low, it can affect the health of sperm and its ability to pass through the female reproductive tract.
Apart from these, sperm health is examined by looking at many factors such as semen volume, liquefaction, and seminal fructose levels while performing the sperm test. After examining all factors in detail, the results are examined and reported to the patient.
What is the Sperm Test Result of a Healthy Individual?
Low sperm count can have many different causes. The first reason is smoking addiction. Smoking addiction is one of the important factors that reduce the sperm count. In addition to smoking, alcohol and drug addiction also affect sperm count. Sperm count can also be adversely affected when there is a deficiency in hormones, depending on the clogged ducts.
Hormones are one of the important factors for reproduction on their own. Since the deficiency in reproductive hormones directly affects sperm production, it increases the possibility of encountering problems in reproduction. Apart from these, mistakes made by couples who want to have children also affect the sperm count. Using natural products unconsciously and continuing to use them uncontrollably, without knowing the limit, does harm to the person instead of providing benefits. Long-term treatment and drugs used during the treatment also affect the sperm count.
IMSI in Sperm Selection
The IMSI (Intracytoplasmic Morpholgically Selected Sperm Injection) method is the magnification and examination of even the smallest cells using special microscopes. In the past, in the microinjection procedures applied in IVF treatments, living sperm cells could be enlarged up to 400 times. However, with IMSI, sperm can now be enlarged between 6000 and 8000 times. It is possible to examine and detect in detail the disorders called "vacuoles" that indicate the intracellular structures of the sperm and their genetic damage.
The IMSI technique is an extremely useful method. Selected sperm injection; It allows advanced morphological analysis of sperm without damaging the living sperm cell. Sperm with the highest fertilization ability are selected and a high chance of fertilization between 20% and 40% can be obtained with the applied microinjection application.
Precautions to be Considered for Sperm Quality
Couples who want to have children should pay attention to egg and sperm health and be careful in this regard. There are many factors that affect sperm quality, such as those that affect egg quality. One of these factors is undoubtedly a healthy diet. A healthy diet is extremely important for every organ in the body, of course also in sperm health.
In addition, exercise is very important in making you more vigorous and increasing your body's stamina and activity. Regular exercise will make you recover in a short time and will positively affect both your mental and physical health. Alcohol and smoking are substances that affect reproductive cells and should be avoided. This is a proven fact as a result of research. If we gather all these under one title, we can say that one should take care of his own health. Nutrition, avoiding alcohol, smoking, exercising regularly will first affect your health and therefore your sperm quality.
This process, which is sensitive and special for couples who want to have a child, is extremely important for them. In this process, prospective parents experience excitement on the one hand and a lot of stress on the other. Hüma IVF Center, which understands the emotions experienced best and does not spare its support by being by their side throughout the process, is always ready to accompany you.
WHAT IS BLASTOCYST TRANSFER? WHAT ARE THE ADVANTAGES OF BLASTOCYST TRANSFER?
Blastocyst transfer, which is one of the advanced in vitro fertilization techniques applied today, is a method that offers a much higher chance of pregnancy to couples who want to have children. The blastocyst transfer method, which is a method that minimizes the possibility of multiple pregnancy, which is frequently encountered in IVF treatments, supports families in making their plans to have a child more effectively. The blastocyst is defined as the 5th or 6th day of the egg becoming an embryo. Before transfer, one or two embryos of the highest quality are selected and the transfer is carried out. This method is among the most important processes of IVF treatment. What is blastocyst transfer, what are its advantages and risks? You can continue reading our article, which includes the details of blastocyst transfer with questions.
What is blastocyst transfer?
Blastocyst transfer, which has an extremely important place in the IVF treatment process, is the process of transferring the embryo created in the laboratory environment to the woman on the 5th or 6th development day. Embryos are followed in incubators in the laboratory and when they reach the blastocyst stage, transfer to the uterus is performed. Blastocyst transfer has many positive contributions to the IVF process, such as enabling better quality embryo transfer and reducing the risk of multiple pregnancy.
What are the advantages of blastocyst transfer?
Blastocyst transfer is a method that has been used frequently in recent years, depending on the developing technologies. In the first years of in vitro fertilization treatment, the expected time for transfer was 48 hours, but this period has been extended in parallel with the developments experienced today. In the blastocyst transfer method, embryos with the highest success rate are selected more easily with transfers made after 5 and 6 days. In general, the advantages of blastocyst transfer can be listed as follows;
The chance to achieve better results against recurrent pregnancy failures, thanks to the selection of embryos with better development potential and compatibility with the uterus,
Reducing the possibility of multiple pregnancy by transferring fewer embryos with high viability,
The chance to observe the embryo development more clearly and healthily,
Freezing of embryos at the time when they have the highest developmental power, that is, at the blastocyst stage,
· Allowing different methods to examine embryo viability.
What is the risk of blastocyst transfer?
The condition that can be encountered frequently as a result of blastocyst transfer is the factor of multiple pregnancy. For this reason, some legal restrictions have been imposed on the number of embryos to be transferred in order to be protected from the risks of multiple pregnancy. For our country, this limit has been determined to be a maximum of 2 embryos. By performing 1 or 2 blastocyst transfers in embryo transfer on the 5th day, both the risk of multiple pregnancy is reduced and the chance of pregnancy is increased. The aim of IVF treatment is to achieve a healthy fertilization. In this direction, better quality but less number of embryo transfers will minimize the risks that may be encountered and will facilitate healthy results.
Who is blastocyst transfer suitable for?
Blastocyst transfer can be applied to all couples with a high number of fertilized eggs and good embryo quality on the 2nd day. Since a single embryo can be transferred in the first two attempts under the age of 35, a blastocyst transfer will be made to them, thus preventing multiple pregnancy. In our country, blastocyst transfer is successfully applied and high success rates are achieved. However, the remaining quality embryos after the transfer are successfully frozen with the vitrification method, which is a new and fast freezing technique, giving couples a second chance.

HOW TO UNDERSTAND THAT INSEMINATION WAS SUCCESSFUL?
Insemination treatment is a method of selecting the sperm that is the highest quality of the sperm taken from the expectant father during the ovulation period, that is, during the period when the probability of conception of the expectant mother is the highest, and then putting it into the womb of the expectant mother. A state of fertilization that has been tried many times by natural means, but no successful results have been obtained, thanks to vaccination treatment, sperm and egg dec easily combined and fertilized. So, how will expectant parents understand this situation when Insemination gives a successful result? We will answer this question and give you more detailed information about Insemination treatment. We wish you a pleasant reading in advance.
What is Insemination?
Insemination is a treatment applied by people who want to become parents but have not been able to achieve this condition by natural means. This treatment, which is performed before starting IVF treatment, is aimed at increasing the chances of pregnancy. Insemination takes place exactly as follows;
· Several necessary tests are applied to prospective parents before.
· Male sperm is taken and the best quality sperm is selected by special procedures.
* Spermatozoa are released into the uterus when the woman's eggs are laid. Here this process is known as the vaccination process.
The vaccination method is a method used in cases where the man's sperm count or mobility is low, when there are problems with the excretion of semen during intercourse, when the woman's cervix is narrow. The cause of infertility cannot be explained in any way.
To Whom Is Insemination Therapy Prescribed?
“Who is the Insemination method applied to?"we can explain the question as follows; It is a form of treatment applied to expectant parents who want to have children, but for various reasons some kind of pregnancy condition cannot be created. For the implementation of this treatment, the man or woman must have some problems that he is experiencing. We can list the problems encountered as follows:
· If there is a lack of sperm count and mobility in a man,
· If there is a problem of unexplained infertility (infertility)
· If the woman has ovulation problems and therefore pregnancy could not be done with egg tracking
· It can be applied in couples who want to accelerate the possibility of pregnancy due to social reasons experienced by couples.
What is the Success Rate of Insemination?
With the development of technology in the medical field and the scientific studies conducted, the success rate of Insemination treatment is quite high. And every day these treatments are being enriched with a new way and it is aimed to increase the success rate of Insemination to the highest level.
When Do the Symptoms of Pregnancy Begin With the Success of Insemination?
There is no difference between the occurrence of pregnancy with Insemination and the occurrence of pregnancy by natural means and the appearance of symptoms in terms of the occurrence of pregnancy Dec In other words, expectant mothers are 3rd of pregnancy, as in naturally occurring pregnancies. from the week she begins to experience signs of pregnancy. These symptoms can be considered as complaints such as dizziness, weakness, nausea and vomiting that occur in the morning. Expectant mothers who have these symptoms can find out if they are pregnant by taking a pregnancy test. 12-14 after Insemination to see if pregnancy has occurred. on the day, the Beta HCG hormone is checked in the blood and it is understood whether pregnancy exists or not. If the pregnancy result is positive, you will need to contact your doctor and undergo an examination to keep it under control. After this examination, a clearer result will be obtained by looking at it with ultrasound and it will be determined whether there is a pregnancy or not.
After Insemination, expectant parents should continue their normal lifestyle. They do not need to change anything in their lives with the introduction of Insemination therapy. In this process, they should only take care of regular and balanced nutrition and protect themselves in the best way. We have shared all the details of the vaccination method with you in this article.
