RESUMO

Providing reasonable expectations to patients with diminished ovarian reserve prior to attempting pregnancy through in vitro fertilization (IVF) is one of the most challenging aspects of fertility care. In some instances, advice from the clinician to pursue more effective treatment, such as donor oocytes, may not be acceptable to the patient. In this case report, a patient is presented who represents a poor prognosis candidate for IVF treatment. She was 43 years old with six prior failed IVF cycles and repetitive basal FSH values above 30 mIU/mL. Presented are the challenges in patient counseling and decision making. In her seventh IVF cycle, which she was strongly counseled against pursuing, the patient experienced the desired outcome of live birth. Increasing reports are emerging of live birth using autologous oocytes among women of advanced reproductive age. These instances, as well as the case of our patient, raise issues commonly encountered in patient counseling in poor prognosis patients. This discussion should include an emphasis on patient goals as well as an acknowledgement that no test for ovarian reserve has a 100% positive predictive value.

RESUMO

In vitro studies show that 5α-androstane-3,17-dione (5α-A) is an important intermediate in the formation of dihydrotestosterone (DHT) from androstenedione (A) in women and men. Many studies involving hyperandrogenism, hirsutism, and polycystic ovary syndrome (PCOS) have measured A, testosterone (T), and DHT, but not 5α-A due to lack of a readily available assay to quantify this androgen. We have developed a specific and sensitive radioimmunoassay to measure 5α-A levels, together with A, T, and DHT, in both serum and genital skin. The present study involves 2 cohorts. Cohort 1 included 23 mostly postmenopausal women who provided both serum and genital skin to measure those androgens. In cohort 2, serum androgen levels were compared between women with PCOS and non-PCOS controls. Tissue-to-serum ratios were significantly higher for 5α-A and DHT as compared to A and T. None of the androgens showed a significant correlation between serum and genital tissue. In serum, 5α-A was significantly correlated with A, T, and DHT. In cohort 2, A, T, and DHT were significantly higher in the PCOS group compared to the control group. In contrast, 5α-A levels were similar between the 2 groups. Our findings support the view that 5α-A is an important intermediate in DHT formation in genital skin. Also, the relatively low levels of 5α-A in PCOS women suggest that it may play a more important intermediate role in the conversion of A to androsterone glucuronide.
