Artificial insemination operation for men mainly includes physical examination, follicle detection, extraction and optimization of semen, artificial insemination and so on. 1. Physical examination: it refers to the comprehensive physical examination and physiological indicators of both men and women. Both men and women should have blood tests to check for the presence of genetic diseases, infectious diseases, serious mental illnesses and other diseases that are not suitable for pregnancy, as well as whether certain physiological indicators are suitable for pregnancy. 2. Follicle testing: The woman needs to monitor the development of the follicles in real time. When the follicles reach about 18 to 20 centimeters in diameter, HCG is injected to promote follicle maturation and ovulation. 3. Optimization of semen extraction: When the woman’s follicles are mature, the man can obtain his own sperm. The semen is cleaned and optimized in the embryo laboratory and AI laboratory so that the semen meets the standard for artificial insemination, i.e. semen processing in artificial insemination. 4. Artificial insemination: Artificial insemination mainly involves injecting optimized male semen into the female uterine cavity through an artificial vas deferens for artificial insemination to complete conception. After the completion of artificial insemination, women are advised to take sufficient rest and avoid strenuous exercise and exertion.
