Alterations in plasma concentrations of testosterone, LH, and prolactin associated with mating in the male rat.

摘要: Abstract The hormonal response of the male rat to sexual activity was investigated in two studies. In first, no evidence a chronic elevation plasma levels testosterone (T), LH, or prolactin (PRL) observed sexually experienced rats compared naive controls. Both groups showed an acute increase all three hormones following mating, but increases shown by group were more pronounced. second study, T, LH and PRL rose exposure mating arena whether it contained estrous female, anestrous other animal. However, considerably larger exposed females. It is suggested that rise anticipation although not same extent as anticipatory may function initiate facilitate behavior.
