[Clinical experimental studies in the treatment of ovarian dysfunction with bromo-ergocryptin (pravidel) (author's transl)].

Among 62 patients with galactorrhoea a corpus luteum deficiency or anovulatory cycles were found in 35 cases by serum progesterone determination, endometrial biopsy or basal body temperature records. 27 patients had a hyperpro-lactenemic amenorrhoea-galactorrhoea syndrome. During treatment with 2.5-5 mg. of Pravidel daily the basal body temperature was recorded, the concentrations of serum FSH, LH, Prolactin and progesterone were determined by radioimmunoassay. Other possible reasons for infertility were investigated. 10 of the 19 patients with normal serum prolactins in the group with deficient corpus luteum or anovulation became pregnant after a short duration of treatment, whereas only 2 of the 16 patients with hyperprolactenemia became pregnant. Among 27 patients with secondary amenorrhoea 11 became pregnant. All these patients had increased serum prolactins. During treatment with Pravidel all patients showed a significant increase of FSH and LH concentrations and a decrease of the prolactin concentrations. The outcome of the pregnancy of the 58 patients who became pregnant during treatment with Pravidel was also reported. 14 of the 58 pregnancies occured following additional treatment with Dyneric or HMG/HCG. Up to now there were 18 term deliveries following uneventful pregnancies. There were no fetal anomalies. The abortion rate was not higher than in the general population. All results show that euprolactinemia is not alone characterized by normal prolactin concentration. The clinical signs and symptoms of galactorrhoea without increase of prolactin over 20 ng/ml. in conjunction with ovarian dysfunction must be classified as dysprolactinemia.
