Pre-ejaculate (also known as pre-ejaculatory fluid or Cowper's fluid, and colloquially as pre-cum) is the clear, colorless, viscous fluid that emits from the urethra of a man's penis when he is sexually aroused.
Many also express concern that pre-ejaculate may contain sperm which can cause pregnancy, using this to argue against the use of coitus interruptus (withdrawal) as a contraceptive method. There have been no large-scale studies of sperm in pre-ejaculate, but some smaller-scale studies suggest that no sperm is present and thus pre-ejaculate is ineffectual at causing pregnancy. It is likely, however, that pre-ejaculate which follows a recent ejaculation will contain sperm, as some ejaculate is always left in the duct after orgasm. many professer in this topic 原帖由 Awaver 于 2009-2-10 16:50 发表 https://www.gdutbbs.com/images/common/back.gif
