IVF is an important part of assisted reproductive technology, which is the common name for in vitro fertilization-embryo transfer technology for infertile patients. The specific operation process steps are as follows: 1. Pre-examination: Both men and women usually need to undergo comprehensive examination 1-2 months in advance, such as semen testing for the male partner and gynecological examination, diagnostic scraping, laparoscopy, anti-sperm antibodies, liver function and hepatitis B and half, routine blood analysis, clotting time and basic endocrine hormone determination, etc. The specific examination items vary from person to person; 2. The medication will be started on the 21st day of menstruation to keep the gonadotropins in the body at a low level, and the menstruation will start around 8 days after the medication. After 3 days of culture, the fertilized eggs will be developed into embryos, which will be placed into the uterine cavity for transfer. For third generation IVF, the embryos need to be frozen and then transferred after testing and screening for blastocysts that do not carry disease correlations. Currently, IVF is a more mature technology and is widely used clinically, with a success rate of 50-60%, so if patients have a need for this, they can be assured of IVF treatment.
