10 amenorrhea-patients and 5 galactorrhea-amenorrhea-patients were treated wi2-Br-alpha-ergocryptine (CB 154) as a specific prolactin inhibitor. Side-effects, such as headaches, dizziness, and nausea could be reduced to a minimum by delivering the drug with the meal at night. Before and under the treatment hormone levels were determined in plasma and 24-hour-urine. In the beginning all 15 patients showed a hyperprolactinaemia with a nearly always simultaneously existing hypogonadotropinaemia and the absence of LH-peaks. Also the estrogen- and progesterone-concentrations were on the lower normal level or extremely suppressed. In all patients CB 154 therapy led to a quick decrease of the prolactin levels, to a regaining of typical LH- and FSH-episodes, as well as to a regeneration of ovarian function. 5 women reacted with an ovulation, 3 became pregnant. The galactorrhea diminished significantly and stopped finally after a treatment of one week to 6 months. Discontinuation of CB 154-therapy, however, often provoked the galactorrhea-amenorrhea-syndrome again. For women with normoprolactinaemic amenorrhea a gestagen- and estrogen-test were carried out in order to classify the amenorrhea-type and it was tried to induce an ovulation with Dyneric. For patients with a strong desire for children and without any organic cause for their sterility, in cases of ovarian insufficiency grade I and II a HMG-HCG-treatment was often indicated. In spite of a precise control in order to avoid an overstimulation of the ovaries about 1% of the Dyneric-treated and even 30% of the HMG-HCG-treated patients developed ovarian cysts. In spite of high doses of gonadotropins only 32,5% of our sterility-patients (group I and II) became pregnant, whereas about 60% of the hyperprolactinaemic amenorrhea-patients (group VI) conceived under CB 154 treatment.

Ovulation-induction agents are commonly used in the treatment of infertility in patients with or without ovulatory disturbances. These agents include clomifene, bromocriptine, gonadotrophin preparations and gonadotrophin-releasing hormone (GnRH) and its analogues. Each agent is associated with its own specific adverse effects. Although many of these adverse effects are benign and self-limited, some, in particular those effects associated with gonadotrophins, may be life-threatening. Commonly noted adverse effects encountered with the use of pharmacological agents to treat infertility include the following. Clomifene has been associated with hot flushes, multiple gestation, visual disturbances, cervical mucus abnormalities and luteal phase deficiency. Similarly, most of the adverse symptoms associated with bromocriptine are short-lived, such as nausea and postural hypotension. On the other hand, gonadotrophin therapy, even when used appropriately, may lead to the ovarian hyperstimulation syndrome (which is occasionally life-threatening) and a high incidence of multiple gestation. Pulsatile GnRH therapy maybe accompanied by similar adverse effects to those of gonadotrophins, but with a far lower incidence. With regards to the long term safety of these medications, the relationship between fertility drugs and epithelial ovarian cancer is controversial, and causality has yet to be proven. Indeed, a working knowledge of the many adverse effects associated with these medications is essential to any physician prescribing ovulation induction agents, in order to ensure maximum patient safety, compliance and understanding.
