"Birth control" is a broad, all-encompassing term that includes pills, injections, patches, diaphragms, condoms, and even surgeries like vasectomies and hysterectomies. And this is just to name
a few.
All of these various methods work in various ways, and they have different side-effects for different people. The most popular birth control method is the
link, which basically acts in the same way as a latex glove. It prevents actual contact with the vaginal fluids for the man, and has a reservoir for the semen, so the woman does not come in contact with that. By restricting contact to vaginal and seminal fluids, the condom both prevents pregnancy and the spread of STDs.
link work in a similar way. They prevent sperm from reaching the uterus, but they do not protect from STDs. Diaphragms go inside women through the vagina and cover the cervix.
The second most popular method of birth control are
link, taken by women. There are various brands of birth control pills, and though each use slightly different methods, they both effectively prevent pregnancy. The main method of doing this is by influencing a woman's horomones so that she does not
link. A woman's ovaries, if left to nature, will ovulate, or release an egg, once during every menstrual cycle (basically, once a month). The egg then implants itself in the uteran wall. But if you take birth control pills, no eggs are released from the ovaries, and the uterus remains egg-free.
Most birth control pills contain
link and/or
link in varying levels (depending on the brand and type of pill). These are sex hormones that are normally low during ovulation. But if the levels of these hormones are high, the body's clock thinks it's not yet time to ovulate, and therefore doesn't. Think of it like your own daily rhythms. It's harder to get up at 7:00AM in November because it's dark outside, and your body thinks it's still time to sleep. Whereas, it's harder to stay asleep in June because the sun has been peaking in your window since 6:00 telling you it's time to get up. Basically, the high levels of estradiol and progesterone tell your ovaries that it's not time to wake up yet - it's still time to sleep. And your ovaries don't have an alarm clock, like you do, to tell them otherwise.
I hope that answered your question. If you need anything clarified, just ask.
