Infertility can be caused by male causes, such as oligospermia, azoospermia, erectile dysfunction, etc., or by female causes, such as abnormal fallopian tubes, polycystic ovary syndrome, etc. Therefore, both men and women should undergo detailed examination before artificial insemination. The male partner needs to undergo semen testing after one week of abstinence, including sperm density, sperm vitality and morphological examination of semen, etc. It takes more than two times for the test to confirm whether the disease is oligospermia or weak sperm. Two days before menstruation, women need to be checked for the six estrogens, vaginal discharge, cervical smear, routine blood tests, blood type, anti-sperm antibodies and anti-cardiolipin antibodies, and anti-Toxoplasma antibodies regardless of whether they have pets at home. In addition, the patency of the fallopian tubes should be checked, such as tubal imaging or hysteroscopy, to ensure that one side of the tubes is open to ensure successful artificial insemination. Both men and women need to undergo immune antibody tests, liver function tests, blood type, and routine blood tests. In addition, tests for infectious diseases such as hepatitis B, AIDS and syphilis are also required. If the results of the tests are all in order, the chances of successful artificial insemination will be greatly improved.
