“Ovarian hyperstimulation syndrome”, also known as Ovarian Hyperstimulation Syndrome (OHSS), in the most basic way; It can be explained as a reaction to the hormones given to women for the development of the ovaries. During IVF treatment, women are given hormone drugs to stimulate and support egg development. When these hormone drugs stimulate the ovaries more than necessary, the syndrome of overstimulation of the ovaries occurs.


How Ovaries Stimulation Happens?

Ovarian hyperstimulation syndrome (OHSS) is an undesirable consequence of IVF treatment. Although the aim of IVF treatment is to develop a large number of eggs, OHSS may occur if more than a certain number of eggs develop.

Women with polycystic ovary syndrome are much more likely to have ovarian overstimulation syndrome. Excessive response to the drugs given to stimulate the ovaries prepares the ground for encountering this syndrome. During the stimulation of the ovaries, there is a fine line between stimulating the desired number of eggs and over-stimulating the ovaries. It is not always possible to determine this point clearly. When there is overstimulation, reducing the dose of ovarian stimulating drugs and not giving the drug for a day or more, if needed, can prevent the excessive rise of estrogen.


Symptoms of ovarian hyperstimulation syndrome can be mild, moderate or severe. These symptoms are;

-Increased ovarian size

- Abdominal pain, bloating, shortness of breath, decreased urination

-Fluid accumulation in the abdominal cavity

-Coagulation disorders

It can be seen as fluid collection in the chest cavity. It is extremely important to follow these situations closely and to get medical support when necessary.


How is Ovarian Overstimulation Syndrome Treated?

OHSS treatment is carried out to relieve the expectant mother, reduce ovarian activity and prevent complications. However, OHSS can be performed in two different ways as drug and surgical treatment. In mild cases, no additional treatment is required other than outpatient follow-up and severe physical activity restriction, and the patient can usually recover in 10-14 days. Moderate and severe cases may require hospitalization and treatment. In most cases, women who have had OHSS can continue IVF. It is still possible to become pregnant despite OHSS, but these symptoms may worsen if pregnancy occurs. In this case, the patient is followed closely under the supervision of a doctor.

IVF treatment; It is the method that offers the highest chance of pregnancy for couples who want to have a baby but cannot conceive naturally. In vitro fertilization method can be applied as a result of unprotected intercourse for more than 1 year, when pregnancy does not occur. Although it is a successful method, it may not always be possible to achieve 100% success in IVF treatments. There are many factors that determine the probability of successful IVF treatment. 


What Factors Depends on Success in IVF Treatment?

In IVF treatment, it is aimed to catch pregnancy in the first time, but pregnancy is not possible for every woman at once. Factors affecting the success of IVF treatment include the age of the expectant mother, weight status, problems in the uterus, hydrosalpinx in the tubes, immune system problems, smoking degree, alcohol use rate, and decreased ovarian reserve. With this; Various male-related conditions such as sperm immobility, severe deformities, and absence of sperm in the semen also affect the success rate of IVF treatment. General statistical data can give you information about the success rate in IVF treatment, but it should not be forgotten that every couple is very special and unique. In IVF treatment, your doctor can better determine your individual chances, taking into account your personalized factors. 


What are the Risks of IVF Treatment?





As with any treatment, there are some risks in IVF treatment. However, some of these risks, which are likely to be encountered in IVF treatment, are predictable and can be intervened early, although these risks are very rare. We can list these risks as follows: Mild bruising, swelling and pain may occur in the areas where the drugs were injected. Overstimulation of the eggs can result in weight gain, nausea, vomiting and bloating. There may be a risk of ectopic pregnancy. Bleeding may occur during egg collection.


What Should Be Done After Unsuccessful IVF?



 Failure of one or more IVF attempts can be extremely challenging, disappointing couples. This situation is extremely natural. One of the most important reasons for a failed IVF treatment is poor embryo quality. Defective and damaged embryos cannot be attached to the uterus after they are transferred to the uterus. However, in some cases, pregnancy may not be achieved despite transferring good quality embryos. Your doctor will evaluate the reasons for the failure of your IVF process in detail to determine what the problem is. These points will be taken into account in future attempts after the problem is determined. Taking a break for at least a month after a failed IVF attempt will also be very beneficial for the process. As developments in the field of medicine increase, it becomes easier to detect and eliminate negative situations. It is important that couples who fail their first IVF attempt should not despair. When conditions are improved, the chances of pregnancy will be higher in subsequent attempts.

Recently, it has been revealed that egg quality obtained from patients with low reserve is lower and genetic problems in the embryo are higher. In this direction, it is aimed to create fewer but better quality embryos by obtaining higher quality eggs with less drugs. Mini IVF appears as a simplified in vitro fertilization practice, unlike the known in vitro fertilization practices performed with daily injections and high-dose drug use. Especially in patients with a low number of eggs or in advanced age, the success rates are higher than conventional treatments. What is mini IVF, who is it applied to and what are the drugs used in its treatment? You can continue reading our article for questions and all the details.


What is mini IVF?



Mini IVF is an in vitro fertilization application that enables the development of fewer but higher quality eggs by using lower doses of drugs. Eggs developed with this method are taken and fertilization is performed by applying the microinjection technique. Embryos formed after fertilization are transferred to the patient, assuming that the probability of attachment is higher.

In addition to the advantages such as less drug use, less cost and less time spent with mini IVF treatment, high success rates can be obtained in patients with a low number of eggs and advancing age.



Who is mini IVF applied to?



In cases where pregnancy does not occur naturally;

Those who want to use hormone drugs less,

At risk of developing OHSS (overstimulation of the ovaries),

Concerned about the daily injection process in IVF treatment,

Those who have problems in the fallopian tubes and are younger than 35 years old,

Having low egg reserve that cannot be increased with treatment,

Looking for a more economical solution than conventional treatment,

People who have tried many times in vitro fertilization but have not achieved a result, and

Mini IVF treatment can be applied to women who want to reduce the possibility of multiple pregnancy.

However, a treatment plan should be made by a specialist by listening to the patient's history of the disease, analyzing their expectations and performing health checks in detail.



What are the drugs used in mini IVF treatment?



Mini IVF treatment is a type of in vitro fertilization that uses little or no medication to increase and develop the number of eggs. In standard IVF treatments, hormone injections are made for 8-10 days to reproduce eggs, while these drugs are not used in the Mini IVF method. Oral tablets and very low dose hormone injections are used instead. With Mini IVF, which is a natural in vitro fertilization method, it is ensured that the highest quality eggs are produced by using the least amount of medication.

Mini IVF method is aimed to obtain better quality eggs with the use of low doses of drugs. At this point, it is possible to determine your treatment plan by consulting your doctor. You can visit our website for more information.
