What happens to sperm when you are on birth control?
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.
It depends on what birth control method you're referring to. If using hormonal birth control this stops fertile cervical mucus being produced, thus the sperm will not survive for long within the acidic environment of the vagina - a few hours to a few days at most. Obviously if you were using spermicide the sperm wouldn't survive more than around 30 minutes to an hour.
Pulling out is not a effective method of birth control. Sperm can actually be present before ejaculation. By pulling out during ejaculation, there is no telling whether or not sperm was released before or not. And seriously, condoms arent that expensive...just go buy some, or go to the doctor to find out information on other forms of birth control.
All birth control pills contain an artificial progestin, which provides most of the contraceptive effect. The progestin thickens cervical mucus to help block sperm from getting to the egg; inhibits ovulation; affects the sperm to make fertilization difficult; and affects the tubes to make it harder for sperm to get to the egg. Combination birth control pills also contain estrogen, which helps control bleeding and has some impact on ovulation as well.
No it will not. However it may help prevent urinary tract infections. If you don't want sperm in there you need to use a condom or some other form of birth control. pulling out, douching, urinating after sex, wearing a jar of gypsy tears around your neck are NOT birth control. Condoms and birth control pills are both very effective if used properly.
How long after you think you may be pregonant do you have to start taking birth control to get rid of the sperm or baby?
Taking birth control if you are already pregnant or it's been days/weeks since you had unprotected sex, will not kill sperm or baby. It WILL however potentially cause permanent birth defects in an unborn child you may be carrying. Birth control is to prevent you from ovulating (releasing an egg) if you were not taking it and got pregnant- starting to take it won't kill sperm that will have already died off or an egg…
A barrier birth control method is one that blocks sperm from reaching the uterus. Examples of barrier birth control methods include condoms, diaphragms, sponges, and cervical caps. Barrier method means there is a physical device to prevent sperm from entering the woman's reproductive tract. Male or female condom, sponge, cervical cap, diaphragm are all barrier methods. Birth Control Pills, IUD, sterilization, withdrawal, rhythm, are not barrier methods. These methods work by preventing the sperm from…
