What is the first generation of IVF?
The first generation of in vitro fertilization (IVF) means that the eggs and sperm of both men and women are combined in the laboratory through in vitro fertilization (IVF) technology, cultivated into embryos, and then implanted into the female uterus to help couples who cannot conceive naturally achieve the goal of fertility. This is a breakthrough in baby assisted reproductive technology, bringing hope to many infertile couples.
Before the implementation of IVF technology, couples need to undergo a series of examinations, including semen analysis, ovarian function test, uterine examination, etc. Doctors will develop personalized assisted reproductive programs based on the examination results. The process of IVF is as follows:
Collect eggs and sperm
In order to collect eggs and sperm, women need to receive ovulation induction treatment to increase the number of eggs. The doctor will determine the use method and dosage of gonadotropin according to individual conditions. Generally, women need to inject gonadotropin every day to promote the development of follicles, and then determine the development of follicles through ultrasonic monitoring.
Men need to provide sperm samples, which are collected by manual ejaculation, ejaculation or testicular puncture.
In vitro fertilization and embryo culture
After egg collection, laboratory technicians will conduct in vitro fertilization of eggs and sperm in culture dishes. Professional technicians will observe the fertilization and determine the number of fertilized eggs.
Next, the fertilized egg will be transferred to the culture dish for embryo culture under specific culture conditions. The incubation time is usually 3 to 5 days, during which the professional team will carefully observe the development of the embryo and select the embryo most likely to be successfully implanted into the uterus.
embryo transfer
After the completion of embryo culture, doctors will determine the best time for embryo transfer according to the development of embryos and the individual needs of patients. Embryo transfer is a simple surgical procedure in which an embryo is implanted into a woman's uterus through a thin tube. After transplantation, patients need to rest for a period of time to ensure that the implanted embryos can be implanted smoothly.
Pregnancy detection and pregnancy maintenance
About two weeks later, the patient returned to the hospital for pregnancy testing. At this time, you can confirm whether the pregnancy is successful by blood test or urine pregnancy test paper. If the result is positive, the IVF implantation is successful and the patient enters the pregnancy period.
During pregnancy, the patient needs to continue to have regular prenatal examination. The doctor will pay close attention to the development of the embryo and the health of the mother to ensure the smooth progress of pregnancy.
Through the above process, the first generation IVF technology provides a safe and effective birth choice for couples who cannot conceive naturally. The IVF technology has been widely used in many hospitals both at home and abroad, helping countless couples realize their dream of becoming parents.
