Spermatoza in semen can stay alive for up to 7 days, so it has plenty of time to wriggle off the pubic hair into the vagina, through the cervix to the back of the uterus and up the uterine horns towards the waiting egg.
The egg lives 24-48 hours, and it ages rapidly after 24 hours so that it becomes harder for conception to occur (particularly for older women).
Cases have been reported of a woman having sex without a condom on Tuesday night and getting pregnant on Saturday when her egg is released.
Women can release eggs twice in a month if under stress or sexually aroused by hot guys. Often happens with teenage girls and their first sexual lover. This is called a lunar moon fertility surge, a lunar month being 29.5 days.
If a man is releasing sperm into the vagina 2-3 times a week, then his partner has a good chance of getting pregnant.
20% of couples who use condoms get pregnant within a year, because of condom tears or microscopic holes, or accidentally touching/brushing the pubic hair with fingers after a condom is taken off.
If a man is releasing his sperm every day, the volume squirted inside the vagina is much smaller - but might still be enough to cause pregnancy.
A guy feels like sex only when his prostrate gland has re-filled with sperm following ejaculation. Young men can refill in a short period of time, while retired men may struggle to refill more than once a week.
Viagra type products relax arteries and veins, so the blood can flow around the body in larger volumes, and pump up a penis much tighter - but it does not mean that more sperm will be ejaculated.
During the excitement of sex, it is easy for a couple to touch the genitals after ejaculation as part of their post-coital afterplay - and this is the biggest cause of pregnancy because the droplets of semen containing the "tadpole" spermatzoa can't be seen by the naked eyes.
"Pre-cum dripping" in highly sexually aroused males can also be a cause of pregnancy when practicing withdrawal before ejaculation. This can be seen in guys with premature ejaculation, who sometimes ejaculate within a few strokes of insertion because the female vagina looks so incredibly delicious between her legs. |
