Low progesterone does not necessarily mean infertility, but low progesterone can affect a woman’s ability to get pregnant. Generally, if a girl’s basal progesterone level is low, to a lesser extent, except for the appearance of menstrual disorders, no other obvious symptoms. In severe cases, the phenomenon of amenorrhea without ovulation will occur, which will lead to a decrease in the probability of conception. In addition, low progesterone is also prone to miscarriage or fetal ejection. However, infertility cannot simply be attributed to low progesterone; low progesterone is only one of the causes of infertility. Infertility can be caused by a variety of factors, including blocked fallopian tubes or ovulation disorders, follicular dysplasia and gynecological endocrine diseases, and semen abnormalities in men are also major causes of infertility. It is recommended to control smoking and alcohol, avoid prolonged fatigue, late night and mental stress, reasonable control of diet, eat more vegetables and fruits, and supplement vitamins, which can help conception.
