First of all, the couple undergoes a comprehensive medical examination, including general physical examination and special examinations: sperm test for the male partner, routine gynecological examination for the female partner, basal body temperature measurement to understand whether there is ovulation, ultrasound to observe the condition of the uterus and adnexa, tubal iodography test, blood sampling to check the level of sex hormones to understand the function of the ovaries, laparoscopy and so on. For couples who are suitable for IVF, the treatment process can be divided into the following steps: first, the female partner is injected with ovulation-promoting drugs according to a certain super-ovulation protocol, the egg growth is monitored by ultrasound, and the eggs are retrieved by vaginal puncture after the eggs have grown to a certain level; at the same time, the male partner’s sperm is preferentially selected, and then the two are combined in vitro and the well-developed embryo is transferred into the female partner’s uterus two days later. The embryo will be transferred into the woman’s uterus two days later and a pregnancy test will be performed 10-14 days later. The entire pregnancy process and the problems that occur during the pregnancy are the same as a normal pregnancy, which is carried to term in October.
