How Does Hormonal Birth Control Prevent Pregnancy

How Does the Morning After Pill/Emergency Contraception Work? | Planned Parenthood Video

Hormonal birth control works by

  • Preventing ovulation
  • Changing the lining of the uterus to prevent pregnancy from developing
  • Thickening the cervical mucus so that sperms cannot travel to the uterus or the fallopian tubes to fertilize the egg

Pregnancy can be prevented when there are no eggs or no sperm to fertilize the released eggs.

Lots Of Women Take Birth Control Incorrectly

If women follow the exact instructions for taking birth control pills every day, at the same time they prevent pregnancy in 99 percent of all cases. But lots of people don’t do that. In real life, birth control pills have a 9 percent failure rate. That means nine of every 100 women using birth control pills as their only means of contraception become pregnant in any given year.

“It’s hard to actually when you’re living a busy life,” Cullins says. “If you take these pills every single day, the chances of getting pregnant is 1 percent. But typically the chance is much higher than that, because people miss pills. This isn’t just true with birth control pills. It’s true with any prescription medication.”

Birth control pills have a higher failure rate than other contraceptives, like intra-uterine devices or birth control rings.

The main difference: Pills have to be taken every day, which leaves more room for human error.

What Is Birth Control

Birth control is anything that is used to prevent pregnancy from occurring. There are various methods of birth control, including barrier methods, timing methods, and hormonal methods.

Barrier methods, like condoms, block sperm from entering the vagina so an egg wont be fertilized. To use timing methods, couples identify a fertile window and use a barrier method or abstain from sex during it.

Hormonal birth control uses hormones to prevent ovulation and sometimes also to thicken the cervical mucus to prevent sperm from getting through. You can take hormonal birth control in pill form or in continuous release from, such as a patch, ring, or implant.

The combined pillarguably the most common form of hormonal birth control, works by preventing ovulation, explains Dr. Perkins. It provides you with a fixed amount of estrogen and progestin, replacing the hormones your ovaries would normally be making.

Missing A Period On The Pill Doesn’t Mean Something’s Wrong

Birth Control Basics: Condoms, The Pill & Patch

Missing a period while on the pill doesn’t indicate anything abnormal, Cullins said, as long as you have been taking the pill consistently and correctly each day.

“It’s not dangerous not to have your period while on the pill,” she says. “What happens is, over time, the uterine lining can become very thin if you take the pill regularly. All that means is if you stop bleeding on the pill, the lining has become so thin that you don’t have anything to bleed from.”

This is not permanent: When a woman stops taking birth control pills, the ovaries start making more estrogen, the uterine lining gets thicker, and women start to bleed again.

Missed periods after taking your pills incorrectly, however, could indicate a pregnancy. In that situation, it’s worth taking a pregnancy test.

How Does Birth Control Stop Ovulation

Hormonal birth control prevents ovulation by inhibiting the signal that triggers the two key hormones that are involved in ovulation: follicle-stimulating hormone and luteinizing hormone . These two hormones will begin to be produced if your body notices a shortage of estrogen and progesterone.

Hormonal birth control provides just enough synthetic estrogen and progesterone hormones to prevent the stimulation of FSH and LH production.

  • Normally, the hypothalamus in your brain detects when your estrogen levels are low, typically during the first days of your menstrual cycle.
  • During certain phases of your menstrual cycle, your hypothalamus releases gonadotropin-releasing hormone . This is the hormone that signals the pituitary gland in your brain to make FSH and LH.
  • Since birth control prevents the hypothalamic message from being sent to your pituitary gland, the pituitary gland does not produce FSH. Without the release of FSH, there is no signal to trigger the growth and development of egg follicles in the ovaries.
  • Ovulation normally takes place in response to a surge of LH that triggers an egg to be is released from the ovary. With hormonal birth control, there is no LH surge, so the egg’s release is not activated and ovulation does not take place.

Hormonal birth control basically keeps you in the same phase of your menstrual cycle on a continuous basis, skipping the release of GnRH and preventing ovulation from taking place.

Does It Cause Side Effects

Not Starting A New Pack Right Away

It is essential to start a new pack of pills the day after finishing the previous one. However, sometimes a person may not have their new package yet. Missing a few days between packs can make the pill less effective at preventing pregnancy.

According to the , anyone who misses two or more pills in a row should use a backup contraceptive method or avoid sexual intercourse until they have taken the birth control pill for 7 consecutive days.

Do Birth Control Pills Have Other Benefits

It is important to keep risks such as blood clots in mind if you are considering to use birth control pills to regulate your period or for reasons other than preventing pregnancy. Is the risk of potentially fatal blood clots worth it to reduce cramping, or might Tylenol or other pain killers be equally effective without the increased risks? Since birth control pills dont actually regulate a womans period, they should never be used for that purpose. If the goal is to reduce menstrual bleeding, then birth control pills can accomplish that, but with risks that may outweigh the benefits.

While all FDA-approved oral contraceptives are proven to prevent pregnancy, some have also been approved for other benefits. However, the benefits of birth control pills approved for PMDDhave mostly been evaluated by comparing them to placebos and not to other birth control pills. They may not be any more effective than safer, less expensive birth control pills for PMDD. So, why didnt the FDA approve these other pills for PMDD? The answer is simple: money. Yaz and other relatively new birth control pills are very expensive, which is why the company selling them was willing to spend the extra money to apply for FDA approval for PMDD. Older birth control pills that are widely available in generic forms cost much less, so their companies have no incentive to pay the millions of dollars it would cost to apply for FDA approval specifically treat PMDD.

Hormonal birth control is designed to prevent ovulation by supplying a steady level of estrogen and/or progestin every day. For pregnancy to occur, an egg must be present in the fallopian tube for the sperm to fertilize. So, when hormonal contraceptives stop ovulation, an egg is not released from the ovary. With no egg for the sperm to join, pregnancy is prevented.

Combination birth control methods prevent ovulation, and progestin-only birth control can also do this.
