The collected eggs are separated according to whether they are mature or not by undergoing certain procedures in the laboratory environment. Sperm is taken from the male wife by masturbation method on the day of egg collection. Sperm is evaluated in the andrology laboratory in terms of number, shape, and movement.
ICSI (Microinjection) is performed by injecting a sperm into each mature egg. In patients with sperm problems, surgical interventions with the methods we call TESE or MESA and sperm obtained from the testicles of patients are injected into the eggs and ICSI is performed.
After the ICSI procedure, it is checked whether eggs and sperm are fertilized in 16-18 hours. Fertilized eggs are called embryos.

After the embryo, the remains of the transferred embryos are evaluated and it is decided whether they are suitable for freezing. With the consent of the patient, embryos can be frozen for 5 years for later use by entering into a contract once a year (as required by the regulation).

One or two of the cells that make up the embryo (blastomere) are taken and their genetic structure is determined before transfer. PGT is inevitable in cases such as advanced age, detected chromosome abnormality in any of the spouses, recurrent miscarries, screening for gender-related diseases.
A pregnancy ( Beta – HCG ) test is performed in the blood 12 days after embryo transfer. According to the results of the test performed in the blood, it is determined whether there is pregnancy or not. Those who test positive are repeated after 2 days. The relationship between the two tests is evaluated and it is decided whether the pregnancy is healthy or not. The first ultrasound is carried out to see if there are a gestational sac or how many sacs (one, twin).
Although sperm count is low or sperm count is normal, the following procedures are applied to people who have fertilization problems until they obtain sperm in the same session, in turn:
This practice is the fertilization of sperm obtained from the testicle with the help of needles by the ICSI method. The pregnancy rate is 25 percent.
During this procedure, the needle enters the test, and the material obtained is looked at whether it contains mature sperm. The pregnancy rate is 25 percent.
It is mostly done under local anesthesia. The liquid obtained by applying a vacuum from testicle tissue with a thin needle is examined under a microscope. If the cell is found, it can be stored frozen and dissolved during the microinjection process.
In cases where sperm cannot reach the semen, the process of fertilization of the egg by the ICSI method of sperm obtained from tissue particles obtained from the testicle as a result of biopsy is called TESE. The pregnancy rate is 30 percent with this method
Most often with local anesthesia, it is a procedure that is rarely performed under general anesthesia. Small tissue samples taken by making a small incisor on the testicle are examined by disintegrating under a microscope. If the cell is found, it can be stored frozen and thawed as needed.
The use of fresh or frozen-thawed spermatozoa obtained from the testicle in IVF treatments does not change the probability of fertilization and pregnancy. However, whether using fresh or frozen sperm, choosing moving ones increases both fertilization and pregnancy rates.
Routine micro tese is applied in our center. The chances of success are 50% better than normal.
In this process called microdissection TESE, the process of taking parts from the testicle is performed under a special microscope. Tubules, which are active sperm production, appear whiter and duller when viewed through a microscope. Tissue fragments are taken from these regions. In the studies where this method is applied, some studies have reported a higher rate of obtaining sperm.
