The delayed anovulation syndrome: influence of hormones and correlation with behaviour.

Experiments were conducted to assess the influence of the ovary and various steroid treatments on the development of the delayed anovulatory syndrome (DAS) in female rats. The influence of neonatally administered androgen on the development of ovarian function and female sexual behaviour was studied. It was found that neither the presence of the ovary nor the administration of oestrogen or androgen affected the time-course of the DAS. Doses of androgen which produced the DAS had little effect on female sexual behaviour and there was no evidence of time-dependent changes in sexual behaviour comparable to the time-dependent changes of ovarian physiology observed during the DAS.
