Generally artificial insemination can be done 3 to 6 times, but it also depends on individual circumstances. Artificial insemination is an artificial assisted reproduction technique for infertile couples with normal follicles, normal sperm and a structurally normal female reproductive tract with at least one functioning fallopian tube. The success rate of artificial insemination is relatively low, and it can usually be done 3 to 6 times depending on the circumstances, but the chances of success after 6 failures are also lower, and other methods of assisted reproduction can be chosen under the guidance of a doctor. Artificial insemination needs to be operated by a professional physician, and can be carried out in a natural cycle or an ovulation cycle, and the number of dominant follicles should be controlled in the ovulation cycle. Before artificial insemination, the endocrine, semen quality, ovulation function and endometrial condition and other related examinations should be well checked. When repeated failures occur, in vitro fertilization-embryo transfer (IVF-ET) technique can be chosen under doctor’s guidance.
