I've actually believed that precum can get you pregnant. But I actually have just found out that as against popular opinions, precum can actually NOT get a woman pregnant

Interesting fact about the semen is that it is produced in different parts of the male reproductive system.
First, let's actually take into account the fact that the semen is different from sperm

Sperm cells are the cells which contain the DNA and actually fertilize a female egg leading to pregnancy

So in semen, which is actually the stuff that comes out when a man ejaculates, there are sperm cells and a whole lot of things which includes proteins, lipids, minerals, water etc

So all of these different parts of the semen are produced in different parts of the male reproductive system and then comes together during ejaculation to be transported out through the urethra and into the female's vagina

So, semen in actual fact contains sperm cells which can get a woman pregnant

But precum, nah. It is produced in a different part of the male reproductive system known as cowper's gland and it's function is to provide lubrication for the penis to be able to perform in the vagina during sex and in actual fact does NOT contain sperm cells which makes it IMPOSSIBLE to make a woman pregnant

But on the other hand, and this is important. If a guy has just ejaculated, some of the semen (which contains the actual sperm cells) could actually be retained in the urethra. So, if this guy decides to go for round 2, lol, the precum could actually carry the semen along...

Except in the case of the guy urinating after sex in order to flush the semen retained in the urethra out... And the typical guy would actually agree with me if they've observed that their urine after sex (or wet dream) usually starts with a cloudy discharge before the clear urine.

What do you think guys, did this shock you as it did to me?

All in all, as a biologist, I'd say, always practice safe sex, stay safe guys
