Artificial insemination and in vitro fertilization have their own different indications, and should be combined with their own and their spouse’s characteristics to choose the appropriate method of conception, and there is no such thing as which one is better in the clinic. 1. Artificial insemination: When the male partner has moderate semen abnormality, such as oligospermia, weak sperm, etc., or when the male partner has impotence or premature ejaculation, which makes the semen unable to enter the female partner’s vagina, or the sperm enters into the vagina, but its vitality is not enough to enter into the uterus, artificial insemination can be chosen as a priority. When the woman is unable to have a normal sex life due to malformation of the reproductive tract or other factors, artificial insemination will be chosen to assist in childbirth. 2. IVF: Infertility caused by tubal factors, such as tubal obstruction and tubal adhesion, is preferred to IVF, i.e. in vitro fertilization-embryo transfer. In addition, severe endometriosis and insufficient ovarian reserve function are also recommended to choose IVF technique.
