Definition of Birth Control Pills
Birth control pills, also known as oral contraceptives, are medications that prevent pregnancy by altering a woman’s hormonal balance. These pills typically contain synthetic hormones estrogen and progestin, although some may only contain progestin, and are taken orally on a daily basis. The pills work by suppressing ovulation, thickening cervical mucus to impede sperm movement, and thinning the uterine lining to prevent implantation of a fertilized egg.
There are different types of birth control pills available, ranging from combination pills that contain both estrogen and progestin to progestin-only pills. Some common brand names for combination pills include Estarylla, Lo Loestrin Fe, and Sprintec. These pills are highly effective at preventing pregnancy when taken as directed, with a failure rate of less than 1% with perfect use.
It is important to consult a healthcare provider before starting any birth control regimen to determine the best option based on individual health needs and preferences. Additionally, birth control pills do not protect against sexually transmitted infections (STIs), so the use of condoms is recommended for dual protection.

How Birth Control Pills Work
Birth control pills, also known as oral contraceptives, work by preventing ovulation, which is the release of an egg from the ovaries. They contain hormones that regulate a woman’s reproductive system and prevent pregnancy in several ways:
1. Hormone Regulation
- Estrogen and Progestin: Combined birth control pills contain both estrogen and progestin hormones. These hormones work together to inhibit ovulation and thicken cervical mucus, making it difficult for sperm to reach the egg.
- Progestin-Only Pills: Also known as mini-pills, these pills contain only progestin and mainly work by thickening cervical mucus to prevent sperm from reaching the egg.
2. Ovulation Inhibition
By suppressing ovulation, birth control pills prevent the release of an egg, thus reducing the chance of fertilization.
3. Cervical Mucus Changes
The hormones in birth control pills alter the consistency of cervical mucus, creating a barrier that makes it difficult for sperm to penetrate and fertilize an egg.
4. Endometrial Changes
Birth control pills also cause changes in the uterine lining, making it less favorable for implantation of a fertilized egg, further reducing the risk of pregnancy.
These mechanisms work together to provide highly effective contraception, with typical failure rates ranging from 0.3% to 9% depending on the type of pill and how consistently it is used.
According to the Planned Parenthood website, birth control pills are 99% effective when used correctly.

Types of Birth Control Pills
There are several types of birth control pills available on the market, each with its own unique combination of hormones and dosages. Some common types include:
- Estarylla: Estarylla is a combination pill that contains ethinyl estradiol and norethindrone. It works by preventing ovulation and thickening cervical mucus to block sperm from reaching the egg. Estarylla is taken once a day for 21 days, followed by a 7-day break.
- Yaz: Yaz is another combination pill that contains ethinyl estradiol and drospirenone. This pill also inhibits ovulation and changes the uterine lining to make it harder for a fertilized egg to attach. Yaz is taken daily for 28 days without a break.
- Ortho Tri-Cyclen: Ortho Tri-Cyclen is a triphasic combination pill that contains varying levels of estrogen and progestin throughout the menstrual cycle. This pill is taken for 21 days, followed by 7 days of inactive pills.
It is important to consult with a healthcare provider to determine which type of birth control pill is best suited for your needs and medical history.
Types of Birth Control Pills
1. Combination Pills
Combination pills contain both estrogen and progestin hormones. These pills are the most commonly prescribed type of birth control pills. Examples include Estarylla, Yaz, and Ortho Tri-Cyclen. They work by preventing ovulation, thickening cervical mucus to block sperm from reaching the egg, and thinning the uterine lining to prevent implantation.
2. Progestin-Only Pills
Progestin-only pills, also known as mini-pills, contain only progestin hormone. They are suitable for women who cannot take estrogen due to health reasons. Examples include Camila and Errin. These pills work mainly by thickening cervical mucus and making it difficult for sperm to reach the egg.
3. Extended-Cycle Pills
Extended-cycle pills, such as Seasonique, allow women to have fewer periods per year. These pills typically contain a combination of estrogen and progestin and are designed to be taken continuously for an extended period, usually 84 days, followed by a shorter hormone-free interval.
4. Low-Dose Pills
Low-dose birth control pills contain lower amounts of hormones compared to traditional birth control pills. They are suitable for women who may experience side effects from higher hormone doses. Examples include Lo Loestrin Fe and Alesse. These pills are effective in preventing pregnancy and have a lower risk of side effects.
5. Emergency Contraceptive Pills
Emergency contraceptive pills, also known as the morning-after pill, are used to prevent pregnancy after unprotected sex or contraceptive failure. Examples include Plan B One-Step and Ella. They work by delaying or preventing ovulation, fertilization, or implantation of a fertilized egg.
6. Continuous-Dose Pills
Continuous-dose birth control pills, such as Lybrel, are designed to be taken every day without a hormone-free interval. These pills eliminate monthly periods but may lead to breakthrough bleeding or spotting. They provide continuous hormone levels to prevent pregnancy effectively.
7. Placebo Pills
Placebo pills are inactive pills included in birth control pill packs to help women maintain their daily pill-taking routine. These pills do not contain any hormones and are taken during the hormone-free interval. They serve as a reminder to start the next pack of active pills.
Overall, there are various types of birth control pills available to women, each with its unique characteristics and benefits. It is essential to consult with a healthcare provider to determine the most suitable option based on individual needs and preferences. Remember to use birth control consistently and correctly to maximize its effectiveness.
