When a guy ejaculates how much semen is there? What is the clear fluid that comes out of a guy’s penis before he ejaculates?

Typically, about a teaspoon of semen is released when a guy ejaculates. If he ejaculates often, the amount usually decreases. That’s normal since it takes about five to seven days for a guy to produce enough semen for a full ejaculation. If he ejaculates often, he would not have had time to build up the supply, so less will come out. There will always be some fluid with sperm released; remember, it only takes one sperm to fertilize an egg!

The fluid that comes out before ejaculation is called pre-ejaculatory fluid or pre-cum, and it comes from the Cowper’s gland inside a guy’s reproductive system. It’s released to clean out the inside of the urethra when a guy gets an erection. The urethra can have leftover urine in it from an earlier trip to the bathroom, and urine is acidic enough to be unfriendly to sperm.

Pre-ejaculatory fluid makes the urethra less acidic and gives the sperm a better shot at surviving the trip through the urethra. Pre-ejaculatory fluid can contain sperm in some guys. Whether or not a guy’s pre-ejaculate has sperm depends on the guy and every guy is different. Also, remember that pre-ejaculatory fluid can carry sexually transmitted diseases (STDs), so a guy should put on a condom as soon as he gets an erection.
