Sperm is not affected by hormonal Birth Control; it does the same thing it does if you're not on birth control, except that there's some decrease in how much sperm can get into the uterus (due to thickening of the cervical mucus). Hormonal birth control affects the egg.
When on birth control, the combined pill usually prevents ovulation, so there is no egg for the sperm to fertilize. If you are also on your period, the uterine lining is shedding, making it less likely for sperm to survive and fertilize an egg. So in most cases, ejaculated sperm would not result in pregnancy during this time.
Birth control doesn't affect the sperm's life span. They can live about five days.
the sperm will end up dying, in the womb or somewhere around where sperm goes.
Yes. However you decrease the chances by taking your birth control correctly and by using condoms.
Spermicide works by killing sperm. The copper IUD works by interfering with sperm motility.
This can be consdiered a form of birth control. Sperm in the mouth does not cause pregnancy. Sperm elsewhere can. Keep the sperm where it will do the least harm.
Nothing
A birth control cap is a soft rubber cap that aids in birth control. The cap is placed inside of a woman and while having intercourse, it aids in keeping sperm away from the uterus.
If the birth control fully works, there won't BE a fetus, birth control will do nothing about an impregnated egg or the baby that it will result in.
It will, for a short period of time, lower your sperm count. Do NOT rely on doing that as a method of birth control however, as all it takes to impregnant a girl is one solitary spermatozoon...You can ejaculate as often as you like, it will not harm you.
If you stop you'll probably end up pregnant. Yes sperm is still in you. Birth control controls the hormones in your body so the birth control is already doing it's job. By the time your body absorbs the sperm or disperses it, ( a couple of days), the birth control hormones are still present so it is unlikely you would get pregnant at this time. But after this, you won't be protected against pregnancy and your chances of becoming pregnant increase every day after that. In other words, it takes a few days for the birth control to stop working even after stopping the birth control.
Because if there is no sperm in the ejaculate there is no fertilization.
