4. 消退期

消退期阴茎的变化
在消退期最明显的生理变化是阴茎勃起消失。它分两个步骤：

  • 在性高潮期后，阴茎大体的勃起立即消退。
  • 但是，它仍维持某种程度的硬度，并持续一段时间，尤其是如果兴奋期和平台期延长的话，这一现象更甚。

另一方面，在无性活动或分心的情况下，阴茎勃起会相当快地消失。

4. Resolution

The change  penis during resolution  
The most visible physiological change during this period is the loss of penile erection which proceeds in two stages:

  • The major loss occurs immediately after orgasm.
  • However, the penis still retains some firmness which may persist for some time, especially if the excitement and plateau phases were extended.

On the other hand, nonsexual activities or distractions can complete the loss of erection rather rapidly.
