Psychoendocrine response to sexual arousal in human males.

The hypothesis is tested that luteinizing hormone (LH) and follicle stimulating hormone (FSH( may be released from the anterior pituitary in response to a psychological state of sexual arousal. LH levels in 10 male volunteers were found to be higher after viewing a sexually arousing film than after a control film. The magnitude of LH response was found to be positively correlated with the subjective evaluation of sexual arousal. FSH levels tended in the same direction bu the predominant and unexpected finding for this hormone was that levels were consistently lower during the first session, when anxiety was high, and higher during the second session, when anxiety was less, whether control or stimulus film had been shown. This study is analogous to those demonstrating the responsiveness of other anterior pituitary hormones to specific psychological states.
