If a couple has been married for two years without contraception and has not gotten pregnant, it is recommended that both spouses go to a specialist infertility clinic. When going to a specialist clinic, both spouses need to be seen at the same time, and the consultation will focus on infertility to find the cause of non-pregnancy, and it is best for both spouses to undergo relevant tests at the same time. For the tests related to infertility, the male partner needs to check the sperm to see if the number, density and vitality of the sperm are normal. The female partner needs to check if the fallopian tubes are open and to check ovulation. If the fallopian tubes are not open, in vitro fertilization-embryo transfer technique can be chosen to help conceive. If the fallopian tubes are open, artificial insemination can be considered. Some women have regular periods but still cannot get pregnant, in which case ovulation can be checked. Some women do not ovulate, and it is difficult to get pregnant in the absence of ovulation. In conclusion, if a couple has not been pregnant for more than 1 year, they must visit a specialist, such as the Fertility Center of the Second Affiliated Hospital of HCM, which is a clinic specializing in infertility, and everyone is welcome to visit.
