"Ok so i have heard after a man ejaculates some sperm is left in the penis and in the vas deferens. then a man can urinate flushing out all the semen? or does urinating not exspell all sperm. and then is there a chance of pregnancy from whatever was left after urinating?"

[DoulaLC]

Urinating after wards can help lessen the odds of pregnancy, but I wouldn't count on it as birth control. Anytime there has been a recent ejaculation, and then reentry, the chance of pregnancy increases. This is one of the main reasons people find the withdrawal method fails.

OK I need to explain the situation. At ten in the morning I masturbated. Then I showered and peed. Then at least once more in the day I peed. Then at ten at night me and my girlfriend fooled around. Is it possible my precum contained semen?

[ajk9211]

So after peeing at least twice and a twelve hour difference could my precum could have contained semen?

[Fr_Chuck]

Of course, if it was a few minutes after you used the bathroom, but after 12 hours, there will be sperm,
There is some sperm even after a few min, just not as many.

[J_9]

Yes, it's possible your fluids contained pre-ejaculate.

Please use REAL birth control if you aren't ready to be a parent.

[ajk9211]

You make no sense you said it woukd and wouldn't contain semen.

[ajk9211]

Do you even know anything on the subject? Because the liquid is the precum.. what I'm aking is after urinating twice and twelve hours would there be sperm in the precum.

[ajk9211]

Precum doesn't contain sperm. It can pick it up from a previous ejaculation. But I've heard that peeing flushes is out

[J_9]

Do I know anything on the subject? HAHAHAHA!

I deliver babies for a living. I think I know a little bit about how that happens!

Pre-ejaculate does indeed contain sperm.

[J_9]

Yes. Pre-ejaculation fluid may contain sperm, which means that a woman can get pregnant even when ejaculation doesn't occur within the vagina.

Found here... Birth control: Can pre-ejaculation fluid cause pregnancy? - MayoClinic.com

[ajk9211]

OK I know that it can contain sperm. However I have read in multiple new studies that pre ejaculate fluid created in the cowpers gland itsellf does not contain any. It can pick up semen in the urethra from a former ejaculation.

That article was from April 2003.

The one I provided was from the MAYO Clinic 2009. The Mayo Clinic is a very reputable medical facility.

[ajk9211]

True but yours also says it may contain sperm, not that it does.

[J_9]

True, mine does say that. So, rather than playing with fire, why not be safe?

[ajk9211]

Yes I understand and I am planning on being safe. I just am curious to know if precum does for sure contain it or does it pick it up from a previous ejaculation

[J_9]

It appears, from the Mayo Clinic study, that it has been found in 41% of the men that it did. Apparently there are not more definitive studies at this time.

So, it's wise to play it safe.

[ajk9211]

Can you put up where you found that?

[J_9]

It's the link I quoted above.
