Low sex hormones may affect normal ovulation, thus affecting pregnancy, and even if pregnancy occurs, it may lead to miscarriage. Low sex hormone, which means that the level of sex hormone in the body does not reach the normal level, may lead to menstrual disorders, affecting normal ovulation of the uterus, or even anovulation, thus affecting conception. In addition, progesterone is a sex hormone that is necessary to maintain pregnancy in women. If the level of progesterone in the body is relatively low, even if pregnancy occurs, miscarriage is likely to occur. If a woman’s sex hormone is too low, she should go to the hospital in time to complete the relevant examinations to clarify the cause of the low sex hormone and which sex hormone she is lacking, and then supplement accordingly under the guidance and advice of the doctor. It is recommended that women with low sex hormones adjust their hormone levels before preparing for pregnancy to avoid adverse effects on the fetus or their health.
