Determining the cause of infertility has a 50% share in the success of pregnancy to be obtained as a result of treatment. For this reason, the story of the couple is first listened to when starting the treatment. Hormone test is requested from the expectant mother and semen analysis is requested from the father-to-be. If there are previous trials or surgeries, the evaluation is made together with the test results.
Following the planning of the treatment, the expectant mother is started on the drug on the 2nd or 3rd day of her menstrual period in order to obtain a large number of eggs.
A fresh semen sample is taken from the father-to-be on the same day as the developing eggs are collected. For patients whose sperm cells are not seen in the semen sample, the procedure we call Micro TESE, obtaining sperm from the biopsy taken from the testicular tissue, is applied.
The best quality selected sperm are placed in the eggs collected from the expectant mother by micro-injection method.
Depending on the number and quality of developing embryos, transfer is planned on the 3rd or 5th day and the embryo is placed in the mother’s womb with a simple, painless procedure.
A pregnancy test performed 12 days after the transfer reveals whether the miracle has taken place or not.
Largest Share in the Storage of Embryos Remaining After Transfer
The basic condition to protect the remaining embryos after the transfer process is to meet the liquid nitrogen at -196c within 1 minute.
To reach this point, two basic methods are used; The first of these is freezing the embryo by applying a gradual series of processes defined as SLOW FREEZE, and the second and most up-to-date technique is VITRIFICATION, which is the technique of keeping the embryo in a glass jar with a shock process without imprisoning it in the ice crystal.
All these processes are applied to the embryos that remain after the transfer, show similar development to the day, and which we call high quality. At this point, although a series of freezing solutions produced for this process, the temperature of liquid nitrogen, the quality of the tubes in which we store the embryos by freezing affect the efficiency of the process a lot, arguably the biggest share depends on the hands and speed.
Eggs and sperm can be stored for 5 years.
Patients who will receive chemotherapy or radiotherapy during cancer treatment should freeze before this treatment as reproductive cells may be damaged. It is also important to freeze the eggs in case of removal of the ovaries, which will cause the loss of reproductive functions. The latest regulation issued by the Ministry of Health especially delights women who have postponed career-oriented motherhood until after the age of 35. Women with reduced ovarian reserve can now freeze eggs with 3 doctor-approved reports. Before the egg freezing process, drug treatment is applied in the same way, and a large number of eggs are developed. The eggs are then thawed and used at the desired time, and embryo development is provided by in vitro fertilization treatment. In men, if no sperm can be found in the semen, if sperm is seen after Micro TESE surgery, freezing can be done. Frozen eggs and sperm are stored for 5 years in tanks containing liquid nitrogen at -196 degrees.
