summary

Test tube baby is a common method of assisted reproductive technology, which is used to help couples who cannot conceive naturally achieve their fertility aspirations. This process involves many steps, including ovulation induction, egg collection, sperm sample collection and in vitro fertilization. The specific operation process of IVF will be described in detail below.

1. Ovulation induction

When women cannot ovulate naturally or ovulate difficultly, doctors will use hormone therapy to promote ovarian development and ovulation. During this process, doctors will regularly monitor the growth of follicles, and determine the best time for ovulation promotion through ultrasonic examination and blood hormone level measurement. Once the follicle develops to the proper size, the next step is egg collection.

2. Egg collection

Egg collection is usually carried out in the operating room, and patients will receive local anesthesia. Doctors use ultrasound technology and slender needles to extract eggs from ovarian follicles. This process usually takes 10 to 15 minutes, and then the collected eggs are transferred to the laboratory for further processing.

3. Collection of sperm samples

At the same time of egg collection, male patients need to provide fresh sperm samples. They can collect semen samples by masturbating or using special condoms in specific rooms of the hospital. Sometimes, if men cannot provide fresh sperm samples, or cannot successfully fertilize with sperm in semen, they can obtain sperm through sperm extraction technology.

4. In vitro fertilization and embryo culture

In the laboratory, doctors will put eggs and sperm into culture dishes for in vitro fertilization. After fertilization, the egg will be cultured for a period of time, usually 2 to 5 days, so that it can develop into an embryo. The doctor will monitor the development of the embryo and assess its quality. During this period, embryo chromosome testing or other genetic testing may be carried out. Finally, one or two healthy embryos will be selected for transplantation into the female uterus. Other healthy embryos can be frozen for future use.

summary

The operation process of IVF includes several key steps such as ovulation induction, egg collection, sperm sample collection and in vitro fertilization. These steps require close cooperation between doctors, laboratory technicians and patients. Through the completion of these steps, couples can have the opportunity to achieve their reproductive aspirations.
