If a couple has a normal sex life and has not had a pregnancy for more than 1 year, it is time to have an infertility test. The items include: 1. Check sex hormones and vaginal ultrasound on the third day of the woman’s period (the third day of redness) to understand the condition of the ovaries and uterus. 2.Check the tubal angiogram about 3 days after menstruation (it is recommended not to do a water pass, it cannot be used as a diagnostic standard). 3, the male partner abstain from sex for 4-5 days to check the semen routine.
