Orgasm men are capable of achieving them is supported by men who have reported having multiple, consecutive orgasms, particularly without ejaculation. Males who experience dry orgasms can often produce multiple orgasms, as the refractory period is reduced. An increased infusion of the hormone oxytocin during ejaculation is believed to be chiefly responsible for the refractory period, and the amount by which oxytocin is increased may affect the length of each refractory period. Another chemical which is considered to be responsible for the male refractory period is prolactin, which represses dopamine, which is responsible for sexual arousal. Because of this, there is
Dysphoric milk ejection reflex for this hypothesis in the original case study. Dysphoric milk ejection reflex Dysphoric milk ejection reflex (D-MER) is an anomaly of the milk release mechanism in lactating women. A lactating woman who has D-MER experiences a brief dysphoria just prior to the milk ejection reflex. The lactating woman who has D-MER experiences a brief period of dysphoria that begins just prior to the milk ejection reflex and continues for not more than several minutes. It may recur with every milk release or only with the initial milk release at each feeding. D-MER always presents as an emotional reaction but may
