Operation process of domestic IVF

Test tube baby is a kind of assisted reproductive technology, which is suitable for some infertile patients. In China, IVF surgery usually includes the following steps: selection criteria, hormone therapy, ovarian stimulation, egg collection and fertilization, embryo culture and selection, embryo transfer, etc.

Selection criteria

The first step of IVF operation is to comprehensively evaluate the patients to determine whether it is suitable for IVF operation. Generally speaking, patients suitable for IVF surgery include: female fallopian tube obstruction, male sperm abnormality, unexplained infertility, elderly infertility, etc. The doctor will conduct a comprehensive examination of the patient, including semen analysis, tubal patency inspection, etc., to determine whether it is suitable for IVF surgery.

On the basis of selection criteria, patients and doctors will discuss whether to perform IVF surgery and sign the informed consent form.

Hormone therapy and ovarian stimulation

Before IVF surgery, women need hormone therapy and ovarian stimulation. This process includes two stages: ovulation induction stage and ovarian stimulation stage.

Ovulation promotion stage: use hormone drugs to promote ovulation, and conduct tubal patency inspection at the same time.

Ovarian stimulation stage: Stimulate ovarian polycystic development by using hormone drugs. The doctor will formulate the corresponding hormone treatment plan according to the specific situation of the patient, and regularly monitor the follicular growth.

Egg collection and fertilization

After the follicle reaches a certain size, egg collection and fertilization are required. This process is usually carried out in the operating room, usually with painless or mild general anesthesia. Doctors use ultrasound guided fine needle puncture surgery to collect eggs into culture dishes.

After obtaining the egg, the doctor conducts in vitro fertilization with the sperm provided by the husband, or injects a sperm into the egg through microinjection technology for artificial fertilization.

Embryo culture, selection and transfer

After fertilization, embryos need to be cultured and selected. Embryos will be cultured in petri dishes for 5-6 days. Doctors will select the best embryo for transplantation by evaluating the appearance of the embryo, cell division, etc.

Embryo transfer is the last step of IVF surgery. The doctor will guide the selected embryo into the uterine cavity through a hose to complete the embryo transfer. After transplantation, patients need a period of rest and observation.

Summary

The procedures of IVF in China include selection criteria, hormone therapy and ovarian stimulation, egg collection and fertilization, embryo culture and selection, and embryo transfer. These steps need the careful operation of doctors and the cooperation of patients, with the assistance of the professional team of the hospital. Test tube baby surgery is an important reproductive choice for some infertile patients, which can help them realize their good wishes in life.
