SUMMARY In a consecutive series of 41 hirsute women clinically classified as benign androgen excess, only 34% were found to have elevated plasma ‘total’ testosterone (T), 22% having subnormal sex hormone binding globulin (SHBG). When expressed as the ratio T/SHBG (‘free androgen index’), 85% of the patients had values above the normal range. It is concluded that this index is more reliable than total testosterone in assessing androgen status in female patients.

Oocyte Recovery

Androgen binding activity, indistinguishable from sex-hormone-binding globulin (SHBG) in serum, has been identified in human follicular fluid by binding analyses (saturation and Scatchard analyses and binding specificity), immunoradiometric assay and Con-A Sepharose chromatography. Follicular fluid was obtained at the time of oocyte recovery from either individual follicles (range 2-7) from seven patients, or as a pool obtained from follicles of several patients who had received a Clomid-human menopausal gonadotrophin treatment to stimulate follicular growth as part of an in vitro fertilization program. Concentrations of SHBG in follicular fluid varied between individual follicles (750 +/- 202 fmol mg-1 protein; mean +/- s.d.; n = 14) and ranged above and below concentrations of SHBG in serum (948 +/- 171 fmol mg-1 protein; n = 5) taken 4 h before oocyte recovery and harvest of follicular fluid. There were strong correlations (r = 0.7-0.9) between the steroid and SHBG contents in individual follicular fluids of two patients. However, the concentration of SHBG in follicular fluid was generally 100-fold lower than that of oestradiol or progesterone, suggesting that SHBG may play some role other than determining the concentration of unbound steroid in the follicle.

Abstract. Sex hormone binding globulin (SHBG) levels were studied for possible effects of oestradiol-17β on SHBG. No change in SHBG plasma was recorded during normal menstrual cycles or during treatment with oestradiol-17β to menopausal women. However, gonadotrophin treatment to amenorrhoeic women to induce ovulation resulted in high oestradiol concentrations and a pronounced increase in SHBG was found during the luteal phase of these cycles. A marked increase of SHBG was also recorded in a woman with pronounced fluctuations of oestradiol during treatment with levonorgestrel sc implants for contraception. In conclusion, effects on SHBG were only found when extraordinarily high levels of plasma oestradiol were recorded.
