Artificial insemination (AI) refers to the delivery of sperm into the female reproductive tract in a non-coital manner for the purpose of procreation. Currently, the main clinical methods performed are intrauterine insemination, intracervical insemination, intravaginal insemination, and intrafallopian insemination. Intrauterine insemination generally uses the washing semen intrauterine injection method, which uses a speculum to expose the cervix, inserts a thin plastic tube into the uterine cavity through the cervical tube, and slowly injects it, and then lies down for 20-30 minutes. This method can select sperm with better vitality, and improve the conception rate. The method of intracervical insemination is to expose the cervix with a dilator, inject 0.2 to 0.3 ml of semen into the cervical canal, inject the remaining semen into the anterior and posterior fornices, and lie down for 20 minutes. Intravaginal insemination is simpler, requiring only a syringe connected to a plastic tube to inject semen into the vagina and lying down for 20 minutes. Intra-tubal insemination means that after ovulation is monitored by ultrasound, insemination is performed via semen injection into the fallopian tube. However, it is important to note that both couples need to undergo a systematic and comprehensive examination before undergoing artificial insemination, and the physical indicators of both couples meet the criteria for artificial insemination before artificial insemination can be carried out.
