Summary

This study investigated the effects of exogenous androgens on the menstrual cycle of eight transsexual females. It was found that the luteal phase decreased from 13.7 ± 0.8 to 11.6 ± 0.8 days, whereas the follicular phase increased in length from 13.5 ± 0.6 to 15.3 ± 0.6 days. With the testosterone levels attained in venous blood (± 4.5 nmol/l) ovulation continued, judged by the rise of basal body temperature and the increase of oestrogen and progesterone blood levels. These results relate hyperandrogenism to luteal insufficiency.
