High prolactin does not usually affect egg quality, but it may affect ovulation. High prolactin is divided into physiologic and pathologic. 1. Physiologic elevated prolactin is usually of short duration, so it usually has little effect on ovulation. 2. If it is a pathologic factor, then it may affect ovulation or egg quality. Commonly, due to abnormalities in the regulation of the hypothalamic-pituitary-ovarian axis, prolactin will be elevated, affecting menstruation, which may affect ovulation or the quality of the eggs discharged is not good, affecting the subsequent fertilization. Therefore, if you find abnormal prolactin, it is recommended to consult a doctor in time and treat the symptoms to avoid affecting the subsequent conception.
