NOTE: This is a serious question, and yes it IS technically possible to become pregnant via a toilet seat if the woman is actually trying to do so. And don't say sperm dies as soon as it hits the air. It only STARTS dying, should the semen dry away enough to not be able to protect the sperm

I have a fear that this woman may have picked up a small droplet of semen that was on a toilet seat and inserted it inside her to become pregnant. Highly improbably, but here are the facts:

First, i don't know if I even masturbated, and even if I did, it would have all been shot into the toilet and not on the seat, but this is a hypothetical situation to try and ease my mind, or to figure out that this woman actually tried to steal my sperm.

The woman was doing a urine pregnancy test, so she had to use the bathroom. I'd wager that if I did masturbate, at least 1 and 1/2 hours have past since then, and most likely 2 hours. Would a small drop of semen on the toilet seat would've dried by then? And even if she used her finger to scoop it up and insert it, what are the chances of pregnancy? I know a chance is there, but I want a likelihood percentage. After all, even if the semen is still wet, there is an issue of viability and the rate of survival. I'm worried that just a little bit of that semen would still be able to find its way ALL the way to the egg, or at least get in far enough to wait for an egg in a few days.

I actually did an informal test of this by having a small drop of semen on the toilet seat. An hour later I wiped it, but it still looked like a drop and was still wet, so all that information about it drying within an hour seems too conflicting.

Hi,
Welcome to ehealthforum,
After ovulation, the egg is alive for about 24-48 hours. If the woman is monitoring her ovulation using BBT chart and cervical mucus, she can predict her probable ovulation day. The sperms can stay alive for hours in wet and warm environment, but die in about 20 minutes if left in dry and hot condition. To fertilize the egg, only 1 sperm is needed, and there are about 40-60 million sperms per ml of healthy seminal fluid. Chances of pregnancy are possible even if 1 healthy sperm is able to reach the egg (during ovulation time). For further clarification, discuss with your doctor/gynecologist.
Take care.
