How to carry out the process steps of the third generation IVF
The third generation IVF is a method to help couples who cannot conceive naturally achieve fertility through in vitro fertilization. The following four aspects will detail the process steps of the third-generation IVF.
1. Preparation of baby test tube
Before the third generation of IVF, both couples need to undergo a comprehensive physical examination to ensure that their physical conditions are suitable for this technology. These examinations include physical examination, blood examination, semen analysis, endocrine examination, etc. At the same time, the doctor will also know the medical history and family history of the couple, and develop personalized treatment plans according to the examination results.
Under the guidance of doctors, women also need ovulation guidance treatment to promote the maturation of multiple eggs. This usually requires taking hormone drugs and monitoring the development of eggs through regular ultrasound and blood tests. Once the eggs are mature, they can be retrieved.
In addition, men also need to provide semen samples for in vitro fertilization. If men can't ovulate naturally, they can obtain sperm samples through sperm extraction technology.
2. Egg and sperm retrieval process
Female oocyte retrieval is usually performed within 36 hours after ovulation. Before surgery, women will receive local anesthesia to reduce pain. Through vaginal ultrasound and puncture technology, doctors can extract mature follicles from the ovary. Usually, multiple eggs can be obtained in one operation.
For men, semen can be obtained through natural ejaculation or other auxiliary methods. Semen samples from natural ejaculation were obtained by masturbation and sent to the laboratory. If the man cannot discharge semen naturally, he can try the seminal vesicle puncture or sperm extraction technology to obtain semen samples.
3. Fertilization and embryo culture
In the laboratory, doctors will fertilize the eggs obtained by women with sperm provided by men in vitro. This can be done by putting eggs and sperm together in a culture dish. After successful fertilization, the egg will begin to develop into an embryo.
Embryos will be cultured in the laboratory, which usually takes 2-6 days. Doctors will closely monitor the development of embryos and select the healthiest embryos for transplantation or freezing. For transplantation, doctors will choose the right time to transfer the embryo back to the female uterus.
4. Embryo transfer and pregnancy testing
Embryo transfer is one of the most critical steps of the third generation IVF. Before transplantation, doctors will judge the best time of transplantation by endometrial thickness, prolactin level and other indicators. The transfer process is usually simple. Doctors insert carefully selected embryos into the uterine cavity with a hose.
After embryo transfer, women need to continue taking hormone drugs to help with implantation and pregnancy maintenance. After about 10-14 days, blood pregnancy test can be carried out to confirm whether the pregnancy is successful.
summary
The third generation of IVF is a complex and sophisticated technology, including the steps of pre test tube preparation, egg and sperm acquisition, fertilization and embryo culture, embryo transfer and pregnancy detection. Through reasonable medical procedures and individualized treatment programs, most couples can successfully achieve three generations of IVF. However, it is also necessary to pay attention to the risks and precautions of this process and carry out it under the guidance of professional doctors.
