The first diagnosis of infertility is called infertility only when there is no contraception after marriage, a normal sexual life, and 1 year of cohabitation without pregnancy. Often women are stressed and think that the problem is their own, but in fact the male partner accounts for 25-40% of infertility, the female partner 40-55%, both partners account for 20-30%, and unknown causes account for 10%. Therefore, once infertility is diagnosed, not only the female partner should be examined, but the male partner should also be included in the examination. The general tests for the female partner are: 1. Basic sex hormone examination, blood collection on an empty stomach in the early menstrual period (day 2-4 of menstrual bleeding), and ultrasound examination of the uterus size and the number of basic follicles in both ovaries, together with sex hormone results for ovarian function evaluation. 2. Tubal examination: including tubal lavage and tubal angiography, which should be individualized according to the patient’s condition. 3.Ovulation monitoring. The male partner can do semen analysis examination at the initial stage and see the results before deciding whether other treatment modalities are needed. Semen analysis examination time: performed within 2-7 days after ovulation. The above is only the general content of the initial examination, and the specific decision should be made according to the patient’s own condition.
