Continued clinical experience with an increasing dosage regimen of clomiphene citrate administration.
Between August 1, 1975, and July 31, 1977, 60 patients with infertility and ovulatory dysfunction were evaluated at the Naval Regional Medical Center, Oakland. Of these, 15 had incomplete work-ups or were lost to follow-up. Of the remaining 45 patients, 2 (4.5%) failed to ovulate at a maximal dose of 250 mg of clomiphene for 5 days with 10,000 units of human chorionic gonadotropin. Of the 43 (95.5%) who did ovulate, 33 conceived. Of these 33 patients, 9 (27%) required greater than 100 mg of clomiphene and/or longer than three ovulatory cycles to conceive. Of the 10 patients who did not become pregnant, additional infertility factors were present in 5. When these 5 were eliminated, the corrected pregnancy rate was 87% (33 of 38). The spontaneous abortion rate was 12.2% and there were no multiple gestations. These results would further emphasize that clomiphene can be used safely and effectively at doses greater than 100 mg or for longer than three ovulatory cycles.
