Disorders associated with endocrine disorders can definitely affect ovulation, and not only ovulation, but possibly the normal onset of menstruation, which can affect both ovulation and menstruation related problems. Endocrine disorders such as polycystic ovary syndrome (PCOS), Cushing’s syndrome (Cushing’s), or hyperprolactinemia (HPH) can lead to abnormal ovulation or irregular menstruation. The treatments for these disorders are different depending on the cause of the disorder. If the primary cause of the disorder is properly treated and cured, the patient’s ovulation and menstruation problems can return to normal, for example, hyperprolactinemia can be treated with bromocriptine to lower the level of prolactin, and polycystic ovary syndrome can be treated with short-acting contraceptives such as Dayne-35.
