Qiao Jie, academician of China Academy of Engineering and president of Peking University Third Hospital, said that artificial insemination refers to a method of injecting male sperm into female reproductive tract in a non-sexual way to assist pregnancy. That is, the collected processed and optimized semen is injected into the female reproductive tract.

"Artificial insemination is different from IVF, just injecting sperm into the female reproductive tract. Oocytes and sperm meet, combine, form embryos and' settle' in the uterus, which is still done in women. " Qiaojie said that according to the different sources of sperm, it can be divided into husband artificial insemination and donor artificial insemination.

Husband sperm artificial insemination is mainly suitable for male infertility, ovulation disorder, unexplained infertility, endometriosis (mild to moderate), cervical infertility and so on. Artificial insemination with donor sperm is mainly suitable for men with azoospermia or serious genetic diseases who are not suitable for childbearing. According to different parts of female reproductive tract, artificial insemination can be divided into vaginal insemination, cervical insemination and intrauterine insemination. Source: People's Daily
