Abstract

Although the technique of in vitro fertilization and embryo transfer (IVF-ET) was developed for couples with untreatable tubal factor infertility. IVF-ET is now being applied to women with other causes of infertility and normal pelvic anatomy. In an effort to determine the treatment-independent pregnancy rate, we retrospectively reviewed the first 245 couples enrolled in the IVF-ET program at Duke University Medical Center. There were 19 treatment-independent pregnancies in 18 women and 3 treatment-associated pregnancies in cycles in which the oocyte retrieval was canceled (in 2 women washed intrauterine insemination was substituted for oocyte retrieval). Six pregnancies were established after an unsuccessful attempt at IVF-ET with additional non-IVF-ET therapy, including washed intrauterine insemination in three couples, and donor insemination in two couples. These observations suggest that (1) a significant number of treatment-independent pregnancies will occur in couples clinically deemed appropriate for IVF-ET, (2) pregnancies can be established in cycles of controlled hyperstimulation without oocyte retrieval, and (3) additional non-IVF-ET therapy can result in pregnancy despite failure of IVF-ET in selected couples.
