Infertility is diagnosed when a couple has normal sexual intercourse and has lived together for more than one year without contraception without pregnancy. If you do not get pregnant for more than one year, you should go to the hospital to check the cause of infertility. First, the male partner’s semen should be checked to see if the density, motility, viability and morphology of the semen are within the normal range. The female partner should check whether the fallopian tubes are open, whether the ovaries are ovulating, and whether there are any abnormalities in the sex six items, A function, ovarian reserve function and other indicators. If there is no problem with these, the doctor will do ovulation monitoring to guide intercourse, and if she is still not pregnant after 3 months, she can do artificial insemination to help her conceive. If the pregnancy is still not conceived after 3-6 months of IUI, IVF can be considered at this time.
