Couples of childbearing age who have been married for more than one year, who do not use any contraceptive measures and who have normal sexual life without getting pregnant, are considered to be infertile. 1. Tubal blockage is the most common cause of infertility, you can do tubal imaging to see if the tubes are open, if there is a problem with the fallopian tubes, you need to undergo recanalization surgery. 2. Female ovarian dysfunction, hormonal problems, abnormal ovulation, no dominant follicles, etc. may also cause infertility. 3. In addition, problems with men’s sperm, such as high sperm deformity rate and long liquefaction time, can also lead to infertility.
