Hormones are chemical messengers of the human body responsible for various body functions. Estrogen and progesterone are responsible for female fertility, menstrual cycle, etc. Hence, doctors prescribe synthetic forms of these hormones to help prevent pregnancy.

Various hormonal birth control methods use a combination of these hormones. However, it is important to note that these birth control methods may help prevent pregnancy, but they do not help prevent sexually transmitted diseases (STDs) (1).

Read this post to learn about the effectiveness of hormonal birth control, who can use it, and the different birth control methods.

How Does Hormonal Birth Control Prevent Pregnancy?

Hormonal birth control works by (2) (3)

  • Preventing ovulation (it does not allow the ovaries to release eggs)
  • 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.

How Well Does Hormonal Birth Control Work?

When used correctly, hormonal birth control can be the most effective birth control for some women. When used as prescribed, only about three in 1000 women get pregnant in the first year of use. However, if you do not use the birth control pills as advised or skip a dose, you are at risk of unintended pregnancy (2).

Side effects

  • Unexpected bleeding
  • No periods
  • Weight gain
  • Headaches
  • Reduced bone density (the bone density may return to normal after you stop getting the injections)

4. Skin patch

  • A thin, sticky patch is worn on the lower abdomen, buttocks, or upper body (not on the breasts)
  • Gradually releases estrogen and progestin
  • Patch has to be removed and replaced once a week for three consecutive weeks
  • Not worn in the fourth week, when you will get your menstrual period
  • According to the CDC, the typical use failure rate of the patch is 7% (1)
  • Using a backup birth control method, such as a condom,is suggested during the first week of applying the patch

Side effects

  • Similar side effects to that of using a pill
  • Might not work effectively for overweight people
  • Some women may experience pain or itching under or around the patch

5. Vaginal ring

  • A small plastic ring is placed in the vagina
  • Releases estrogen and progesterone to prevent pregnancy
  • Left inside for three weeks and removed in the fourth week to get the periods
  • A fresh ring has to be inserted after the fourth week.
  • Some doctors recommend leaving the ring in for five weeks before replacing it with a new one.
  • Using a backup birth control method, such as a condom, is suggested in the first week after insertion.

Side effects

  • Similar side effects to that of contraceptive pills or skin patches
  • Increased vaginal wetness (6)

6. Intrauterine devices (IUD)

  • An IUD or IUS (intrauterine system) is a small, flexible T-shaped plastic device
  • Two types are available: copper IUDs and hormonal IUDs
  • Mirena, Skyla, Kyleena, and Liletta are four types of hormonal IUDs
  • Hormonal IUDs use progestin to thicken the cervical mucus and prevent the sperm from meeting the egg; they may also prevent ovulation
  • Copper IUDs prevent the sperm from reaching the egg and may prevent the egg from latching to the womb
  • Last for several years but are not permanent
  • Your healthcare provider can remove the IUD whenever you want to get pregnant
  • The Mirena and Liletta IUDs work for up to seven years, Kyleena up to five years, and Skyla up to three years (7)

Side effects (8)

  • Irregular periods or no periods when the hormonal IUD is inserted
  • Pain at the time of IUD insertion
  • Cramps or backache for a few days after hormonal IUD insertion
