If you do not get pregnant after more than one year of normal sexual intercourse without contraception, consider the possibility of infertility. The male partner needs to check the sperm quality and related immunological tests, while the female partner needs to check the ultrasound to see how the uterus, adnexa and endometrium are, whether there are fibroids, ovarian cysts, and whether there are polyps or excessive hyperplasia in the endometrium, which can affect the fertilization of the egg. Then check the female hormone levels to see if there are any endocrine disorders, such as abnormal estrogen and progesterone and high testosterone, which can affect ovulation, and monitor ovulation. It is also necessary to further check whether the fallopian tubes are open, if they are not, it will also affect pregnancy. Women also need to check the immune examination, such as anti-sperm antibodies, anti-endometrial antibodies, etc. In short, if you are not pregnant and have normal sex for more than a year, it is recommended that both spouses go to the reproduction department for relevant examinations to identify the cause and then treat the problem.
