title: [Rate of pregnancy in the treatment of sterility during spontaneous and therapy cycles].
abstract: Serum hCG was determined in 231 infertility patients in the late luteal phase of spontaneous and therapeutic cycles. The aim was to establish whether the discrepancy between the high number of induced ovulation cycles and the far lower cycle-related pregnancy rate can be explained by subclinical abortion. In 16.7% of spontaneous cycles hCG was positive; in 16.8% of these cases clinical pregnancy subsequently occurred. The rate of biochemically detectable pregnancies was no higher under endocrine therapy. However, under treatment with clomiphene, epimestrol, prolactin inhibitors and glucocorticoids the rate of clinical pregnancies was almost twice as high, and after hMG/hCG therapy clinically demonstrable pregnancies developed from biochemically identified ones in 76% of the cycles. The investigations show that a stimulation therapy leading to ovulatory cycles after multifollicular development increases the clinical pregnancy rate without resulting in a higher rate of very early abortions.
