When women experience menstrual disorders such as amenorrhea, most of them are unable to conceive. This is because the ovarian secretion of hormones is abnormal during this period, and there is an ovulation obstacle, usually resulting in the absence of eggs. Thus, sexual intercourse during this time generally does not lead to conception. However, a very small number of women may experience occasional ovulation during amenorrhea. If they have normal sexual relations without contraception during this time, conception could still occur. Nonetheless, many women have abnormal hormone levels during amenorrhea, so even if pregnancy occurs, the abnormal hormone levels in early pregnancy could lead to complications such as missed abortion and miscarriage. It is recommended that women who want to conceive should first undergo regular treatment to restore normal menstrual cycles and resume ovulation before actively trying to conceive.
