The therapeutic effect of parlodel in the polycystic ovary syndrome

: Parlodel (2.5-50 mg/day) has been given for 1 to 7 days to 33 patients with the polycystic ovary syndrome (POS). The ovulatory menstrual cycle returned in 10 (30%) patients and 4 of them conceived. Pretreatment cycle disturbance persisted in 6 (18%) patients. Parlodel reduced mid-follicular mean blood LH levels to values of normal women. Some decrease in blood testosterone levels occurred only in the second phase of the cycle. Estradiol test in 6 patients showed normal positive and negative feedbacks in the hypothalamic-pituitary-ovarian axis. Parlodel treatment reduced basal and estradiol stimulated pituitary gonadotropin secretion. It is suggested that parlodel may be used in ovulation induction in a proportion of POS patients.
