Premenstrual tension and functional infertility. Aetiology and treatment.

17 women with premenstrual symptoms received bromocriptine (CB 154) and placebo in a double-blind crossover manner. 5 because pregnant and 10 who completed 2 cycles showed significant improvement in breast symptoms, oedema, weight gain, and mood with bromocriptine. Prolactin concentrations were suppressed. In 34 women with premenstrual symptoms, who had been warned of possible increased fertility, bromocriptine 2-5 mg twice daily from the 10th day of the menstrual cycle for 1--11 months gave marked or complete relief. 45 women attending the infertility clinic took 2-5 mg bromocriptine twice daily for 186 cycles; 23 became pregnant, 2 had marked relief and 20 complete relief from premenstrual symptoms. The relief of premenstrual symptoms by bromocriptine may be due to suppression of prolactin concentrations, which may be a major factor in premenstrual syndrome.
