About Hormonal Contraceptives

For the most part, all hormonal contraceptives—including the pill—piece of work in the same way to prevent pregnancy. Information technology doesn't make a divergence whether the hormonal birth control method is a combination drug containing both estrogen and progestin or if information technology is a progestin-just selection.

All hormonal contraceptives contain manufactured hormones that mimic those that directly the menstrual cycle. Taking them on an ongoing basis inhibits the cycle and prevents pregnancy from occurring.

Using estrogen and progestin together prevents ovulation while causing changes in the uterus and cervical mucus that brand pregnancy virtually-incommunicable.

To exist nearly effective, hormonal contraceptives must be used consistently and correctly. Every bit a group, they are between 92% and 99.9% constructive.

How the Pill Works

There are three ways that the pill works to forbid pregnancy:

Ovulation

The primary way the pill works is by preventing ovulation during the monthly cycle. So, if the ovary does not release an egg, then sperm cannot fertilize an egg to cause pregnancy. The pill may also make the fallopian tubes less probable to motion an egg toward the uterus.

By inhibiting the natural hormonal fluctuations during the menstrual bike, the pill prevents follicle-stimulating hormone (FSH) levels from rising. Without ample FSH, ovulation cannot occur.

Cervical Mucus

The adjacent way that the pill prevents pregnancy is by thickening the cervical fungus, which is a gummy fluid establish around the opening of the uterus. The pill makes cervical mucus stickier than normal, reducing the power of sperm to laissez passer through the cervix and reach the egg.

Under normal circumstances, the fungus will sparse when ovulation occurs, which eases the passages of sperm and provides them a hospitable environs.

Endometrium

The final way that the pill works to prevent pregnancy involves the endometrium, which is the uterine lining. Hormonal contraceptives thin the endometrium and make it far more difficult for a fertilized egg to implant. Without implantation, a fertilized egg cannot receive the nutrients and claret needed to survive and grow.

Under normal circumstance, the endometrium volition thicken during ovulation to create a identify where a fertilized egg can implant and grow.

Placebo Week

Some hormonal methods include a placebo calendar week, just not all hormonal methods take a placebo week. Placebo week is a time when your pill pack contains placebo pills ("sugar pills") with either no hormones or reduced hormones.

The placebo week tin vary based on the contraceptive types:

• For a typical 28-day pack of combination birth command pills, the fourth week is the placebo week.
• For extended cycle pills (continuous nativity command) with a 91-day pack similar Seasonique and LoSeasonique, calendar week 13 is the placebo calendar week.
• For a 21-twenty-four hours pack, like Loestrin, the quaternary week is the placebo calendar week and at that place are no pills to take this week.
• For a 24/four-day pack, such every bit Yaz or Beyaz, the concluding 4 days are the placebo time.
• For the NuvaRing, you take the NuvaRing out after calendar week 3 and do nothing during calendar week 4, which is the placebo calendar week.
• For the Ortho-Evra Patch, yous put on a new patch during weeks ane, 2, and 3. You lot do not use a patch during week 4, which is the placebo week.

The placebo week is important in that it helps you maintain a consistent habit of taking a pill every mean solar day, rather than stopping and starting. Moreover, you are likely to have your period during this week, which is comforting for many people.

Even though you are being exposed to few, if whatsoever, hormones during the placebo week, the level of protection remains unchanged. Every bit such, you lot do not need boosted forms of contraception to prevent pregnancy.

A Word From Verywell

The pill, as well as other forms of hormonal contraception, work in more one way. They can preclude ovulation, they tin lead to a thicker cervical mucus to hinder the passage of sperm through the cervix, and they tin can change the lining of the uterus in a way that inhibits implantation if fertilization occurs.

The pill continues to work throughout the month, even when you are taking placebo pills—this means that additional forms of contraception aren't needed during the placebo time.

With that said, the pill does not reduce the risk of sexually transmitted diseases, including HIV. For this, condoms offer the best means of protection.
