Most women will tell you about 10 times a day!
Get pregnant. Or extract it from a pregnant woman's urine.
It is a "classic" test to determine if someone is pregnant or not. It is done by injecting subcutaneously the woman's urine to the frog, and after few hours, checking the frog's own urine. If the forg's urine contain sperms, the woman is pregnant. It is because the pregnant woman's urine contain hCG, a hormone that is made by placenta.
Yes.
Yes, of course they can. Everyone knows that.
Yes, they can using a special process they can determine whether not a woman is pregnant
No, normal urine does not contain sperm. If there was sperm in the toilet then it would still be impossible for the woman to get pregnant in this way as humans require internal fertilisation
boys don't get pregnant and urine can't do it
A urine pregnancy test tests for the "preg hormone" in the urine, which is at a higher level when a woman is pregnant. However, I'm not sure what you're trying to accomplish; a pregnancy test isn't a "Pass/Fail" scenario; it tells you if you're pregnant or not. Male urine on a pregnancy test should test negative.
The urethra. Female ejaculation is often mistaken for urine, but it's not.
A woman's body secretes a hormone while pregnant which can usually be detected on a home pregnancy test a week or two after implantation (a woman's body doesn't know it's pregnant until implantation and therefore doesn't secete the hormone until that happens) of the fertilized egg (which is about a week after conception). The hormone is in the blood stream which is filtered by the kidneys which create urine. Therefore the hormone can be detected in urine.
Mixing water with urine from a pregnant woman will not affect the accuracy of a pregnancy test result. The presence of hCG hormone in the urine is what determines a positive pregnancy test result, not the addition of water.
