Combined therapy with bromocriptine and clomiphene citrate for patients with normoprolactinemic amenorrhea.
The purpose of this study was to investigate the combined effect of bromocriptine (Brc) and clomiphene citrate (Cl) treatment on 40 patients with normoprolactinemic amenorrhea who failed to respond to Cl alone. The ovulation rate in this treatment was 57.3% (23/40) in the 40 cases, 55.6% (99/178) in 178 cycles; the pregnancy rate was 26.7%. This treatment was effective in 14 of 21 women with polycystic ovary-like syndrome (66.7%). Among those women who responded to treatment, prolactin (PRL) and LH levels were significantly decreased. Estradiol and progesterone levels were significantly increased in the patients who responded. Before treatment, the responsiveness of LH to LHRH among responders to Brc/Cl therapy was significantly higher than among the nonresponders. After treatment, the LH-releasing response following a conjugated estrogen injection in the patients who responded to the treatment was significantly greater than that in the patients who did not respond. The results suggest that the therapeutic effect of this treatment may be primarily due to the restoration and improvement of the impaired hypothalamo-pituitary axis.
