| Popis: | Forty-nine patients in whom clomiphene citrate failed to induce ovulation were treated for 177 cycles with a fixed low dosage of menotropin. Among these 49 patients, there were 24 pregnancies. Among these pregnancies were two that were multiple and three spontaneous abortions. In only one treatment cycle was there a hyperstimulation syndrome. These patients were divided into three clinical groups: the secondary amenorrheic patient, the oligo-amenorrheic patient, and the patient with poor corpus luteum function. There was no statistically significant difference in the pregnancy rate per month among all groups during the first three treatment cycles (average value, 0.07). However, there was a statistically significant improvement in the pregnancy rate per month in the group with secondary amenorrhea and the group with poor corpus luteum in the last three treatment cycles, as compared with the first three treatment cycles (P = 0.05; average value, 0.75). The oligo-amenorrheic patients, on the other hand, during the last 3 months of treatment, had no statistically significant increase in the pregnancy rate per month. These data suggest that menotropin therapy may have a priming effect. These data do not fit the currently accepted model of a constant pregnancy rate per month for all patients. The data suggest that caution should be exercised before combining patient groups when evaluating the results of menotropin therapy. |
