Hypersexuality may be associated with menopause, brain lesions, polycystic ovary syndrome, thyroid disorders, and schizophrenia. 1. In menopausal women, estrogen secretion decreases, and the negative feedback leads to a feedback overproduction of gonadotropins, and thus hypersexuality can occur. 2. Patients with pituitary and gonadal lesions have an increased secretion of gonadotropins and may also experience hypersexuality. 3. Patients with polycystic ovary syndrome (PCOS) commonly experience hypersexuality. Other symptoms include irregular menstruation, acne, and seborrheic dermatitis. 4. Hyperthyroidism in the early stages of the disease may be associated with hypersexuality, especially in patients with mild hyperthyroidism. 5. Patients in the early stages of schizophrenia may exhibit hypersexuality and may engage in obsessive behavior with the opposite sex. Sexual arousal may also be due to other reasons, and those who have this condition may consult a doctor to find out the reasons.
