Complete process of three generations of IVF
The third generation IVF technology is an assisted reproductive technology, which helps couples who are difficult to conceive or unable to conceive naturally to achieve their reproductive aspirations through artificial means. The complete process of the third generation IVF will be introduced in detail below.
1. Initial preparation stage
Before three generations of test tube babies, couples need to undergo a series of physical examinations. The doctor will assess the woman's ovarian function, fallopian tube patency and uterine health. The man needs to have semen examination to determine the semen quality. In addition, genetic counseling and genetic testing are also needed to screen potential genetic disease risks.
Once the preliminary examination results show that the couple is suitable for three generations of IVF, the doctor will determine the best ovulation time according to the woman's menstrual cycle.
2. Ovulation monitoring and egg collection
During the ovulation period, doctors will use ultrasound to monitor the development of follicles. Once the follicles are properly developed, doctors will inject human chorionic gonadotropin (HCG) to promote follicle rupture and egg release.
About 36 hours later, the doctor will perform an egg collection operation. This operation is usually performed under general anesthesia. Doctors use ultrasound guided slender needles to puncture the ovary and collect all the eggs.
3. Sperm extraction and embryo culture
At the same time, the man needs to provide semen samples. Doctors will use special techniques to process semen, and extract the most active sperm for egg fertilization. Fresh semen or frozen sperm can be used for fertilization.
After fertilization, the eggs will be cultured in the laboratory, which usually takes two to five days. Doctors will closely monitor the development of the embryo and evaluate the quality of the embryo.
4. Embryo transfer and pregnancy
Once the embryo is cultured, the doctor will transfer the embryo into the woman's uterus. This procedure usually does not require anesthesia, but gently places the embryo into the uterus through a slender catheter.
After embryo transfer, couples need to wait several days to several weeks to test whether the pregnancy is successful. Once the pregnancy is confirmed, the woman needs to continue to carry out pregnancy monitoring and pregnancy health care.
Summary
The complete process of the third generation IVF includes the initial preparation stage, ovulation monitoring and egg collection, sperm extraction and embryo culture, as well as embryo transfer and pregnancy. When carrying out this technology, couples need to go through a series of physical examinations, including genetic counseling and genetic testing. The doctor will determine the best ovulation time according to the woman's menstrual cycle, and then conduct egg collection. After fertilization, the eggs will be cultured in the laboratory, and the doctor will evaluate the quality of the embryo. Finally, the embryo is transferred into the woman's uterus. This process may require many attempts, but for those couples who cannot conceive naturally, the third-generation IVF technology provides a way of hope for them to achieve their reproductive aspirations.
