In in vitro fertilization, the embryo obtained by combining the eggs collected in the laboratory environment and the man's sperm is placed into the uterus using appropriate techniques and at the appropriate time.
The transfer process does not require sedation. 5-minute sedation can be applied to very sensitive individuals. It is also done in an in vitro fertilization center. The patient's bladder must be sufficiently full during the procedure. Because during the transfer, abdominal ultrasound is applied to check whether we are transferring to the right place.
Transfer is a painless procedure. Having the patient lie down or rest for days after the procedure does not affect the result. Just 1-2 hours of rest is sufficient. It will be sufficient not to have sexual intercourse or to do very active sports after the procedure.
A pregnancy test is performed 12 days after the transfer.
Egg collection process in in vitro fertilization
p>
Egg collection in in vitro fertilization is a procedure performed under short-term sedation and sterile conditions. It takes approximately 10-15 minutes and the patient is sent home 2 hours after the procedure. It is painless as it is performed under sedation.
In order to perform the egg collection process, an egg development treatment is performed for approximately 10 days. 35-36 hours after the cracking needle, the collection process is carried out by entering through the vagina with a special needle attached to the tip of the vaginal ultrasound.
The embryologist processes the collected eggs and combines them with sperm. Thus, the embryo is obtained.
What are the factors affecting the success of in vitro fertilization?
The process performed in in vitro fertilization is roughly based on the egg taken from the woman. It is the combining of sperm taken from a man outside the body in a laboratory environment and obtaining an embryo. This resulting embryo is then returned to the woman's uterus and pregnancy is expected.
Egg quality deteriorates as the woman gets older, the reserve decreases and our options become very limited. Based on this, the woman's age is one of the most important factors. Every newborn girl is born with a certain number of eggs, which are used during the reproductive years. After the age of 35, egg reserve declines rapidly. For this reason, the woman's age is the issue we should pay most attention to.
Good sperm quality and motility undoubtedly makes the embryologist's job much easier. An important obstacle is overcome in order to obtain healthy and high-quality embryos.
It is important for couples who will undergo in vitro fertilization to be mentally prepared for the situation. Even the couples' eating habits and lifestyles will affect success.
If a possible genetic factor is considered in recurrent in vitro fertilization failure, the possibility of making a genetic diagnosis before embryo transfer is also very important. This technique, which we call preimplantation genetic diagnosis, is now widely used. This way, we make sure that we transfer a genetically completely normal embryo.
What are the stages of in vitro fertilization?
Couples applying for in vitro fertilization Treatment is started after all results are evaluated. The first step is the enlargement of the eggs in the woman. Normally, every woman who does not use ovulation medication develops one or 2 eggs during each menstrual period. In in vitro fertilization, the aim is to ensure that all eggs that are silently waiting to grow grow at the same time. Ideally, the target is to reach 12 eggs. However, the response of patients to the hormone medications used may be very different. Normally, this number cannot be reached in a case where the ovarian reserve is already low. Sometimes, as in cases of polycystic ovary syndrome, eggs are obtained that are much larger than normal. Too little or too much is not a desirable situation. After approximately 10 days of drug treatment, the eggs reach the desired size. Sometimes this period may be extended depending on the response. Vaginal ultrasound and estradiol hormone measurement in blood are used for follow-up.
The second stage is egg collection. This procedure is short-term, performed under sterile conditions and with anesthesia. For the procedure, a special needle is added to the tip of the vaginal ultrasound and entered from below to reach the ovary and collect the eggs. The collected eggs are evaluated instantly.
On the day of egg collection, a sperm sample is taken from the man. Now it is time to fertilize the sperm and eggs directly under the microscope. The embryologist performs the procedure under a special microscope. Sometimes, one-on-one fertilization is not performed, sperm are placed around the egg and spontaneous fertilization is expected.
After fertilization, an embryo is formed. Embryos are kept in very special areas and their development is monitored. normal y In pregnancies that occur from birth, the embryo is nested in the uterus on the 5th day. Based on this principle, the embryo is transferred into the uterus, often on the 5th day, sometimes earlier.
Sometimes, after the egg collection process, the uterus is left to rest for 1-2 months, during this period the embryos are frozen, thawed again at the time of transfer and transferred. is done.
