http://en.wikipedia.org/wiki/Refractory_period_(sex)不应期(性方面)
An increased infusion of the hormone oxytocin during ejaculation is believed to be chiefly responsible for the male 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.[6] Because of this, there is currently an experimental interest in drugs which inhibit prolactin, such as cabergoline (also known as Cabeser, or Dostinex). Anecdotal reports on cabergoline suggest it may be able to eliminate the refractory period altogether, allowing men to experience multiple ejaculatory orgasms in rapid succession. At least one scientific study supports these claims, although cabergoline is a hormone-altering drug and has many potential side effects. It has not been approved for treating sexual dysfunction.
在射精过程中催产素分泌的增加被认为是导致男性不应期的主要因素,而催产素所分泌的量可能影响了不应期的长短。另外一个认为影响男性不应期的化学物质是催乳素,它通过抑制导致性唤起的多巴胺来产生作用。因此,现在有些药具有实验性的功用来抑制催乳素。例如卡麦角林。有些关于卡麦角林的轶闻性的报告提到了它可能会消除男性不应期,允许男性在
快速短时内体验多重射精高潮。至少一个科学研究提供了这些论据。不过由于卡麦角林是一种改变荷尔蒙分泌的药物,有着许多潜在的副作用,所以它尚未被核准成为治疗性机能紊乱的药物。
