How does hormonal contraception work?


The market offers countless ways to effectively protect yourself from conception, and hormonal contraception is one of the most popular methods. But how exactly does it prevent pregnancy and how does it affect your menstrual cycle? Read on to learn how this method works and what you can expect.

How does hormonal contraception prevent conception?

Hormonal contraception typically comes in the form of pills, patches, injections, rings, or (hormonal) IUDs. This type of contraception uses synthetic hormones to prevent pregnancy. It can be progestin alone, a synthetic version of progesterone, or a combination of progestin and estrogen.

Hormonal contraception primarily prevents conception by:

  • Suppressing the production of certain sex hormones, thereby preventing ovulation in some women (other women may still ovulate)
  • Thickening the cervical mucus and making it difficult for sperm to pass through
  • Altering the uterine lining, which prevents egg implantation if sperm fertilization occurs

Do I have a period while using hormonal contraception?

The menstrual period refers to the shedding of the uterine lining, which occurs due to a drop in hormones when the released egg is not fertilized. Therefore, ovulation is essential in this process. Hormonal contraception affects the menstrual cycle using synthetic hormones. When hormonal contraception prevents ovulation, natural menstruation does not occur. Instead, during the expected week of the month, withdrawal bleeding occurs, caused by a drop in hormone levels when you temporarily stop taking active pills (or patches and other methods).

Hormonal and non-hormonal contraceptive methods

Contraception that prevents pregnancy through synthetic hormones comes in various forms: oral pills, injections, patches, or (hormonal) intrauterine devices.

However, you can also effectively protect yourself without hormones: condoms, spermicidal gels, non-hormonal intrauterine devices, diaphragms or caps, or natural family planning, which includes the symptothermal method, which is based on measuring basal body temperature, monitoring changes in cervical fluid, cycle length, and other accompanying symptoms.

Each method may have its benefits and drawbacks, but it is entirely up to you which form of contraception suits you and which you choose.
