What Is Progesterone-Only Birth Control?
Progesterone-only birth control uses a synthetic form of the hormone progesterone (progestin) to prevent pregnancy. Unlike combination birth control pills, it contains no estrogen. It works by:
Thickening cervical mucus to block sperm
Thinning the uterine lining to prevent implantation
In some cases, suppressing ovulation
Progesterone-only options are available in several forms, including:
Mini-pills (oral tablets taken daily)
Injections (such as Depo-Provera)
Hormonal IUDs (like Mirena, Kyleena, or Skyla)
Pros and Cons of Progesterone-Only Birth Control
This method offers benefits for people who can’t take estrogen but does come with trade-offs. Here’s a comparison to help you decide:
| Pros | Cons |
|---|---|
| Safe for those who cannot take estrogen (e.g., migraines, clotting risk) | Must be taken at the same time every day |
| Safe to use while breastfeeding (doesn’t affect milk supply) | May cause irregular or unpredictable bleeding |
| Fewer hormonal side effects compared to combination pills | Less effective than combination pills with typical use (91% vs. 93%) |
| Quick return to fertility after discontinuation | Does not protect against sexually transmitted infections (STIs) |
Who Should Consider Progesterone-Only Birth Control?
Progesterone-only birth control is often recommended for people with the following considerations:
Ideal Candidates
Breastfeeding individuals: This method is considered safe during lactation and does not impact milk supply.
Those with estrogen-sensitive conditions: Individuals with migraines with aura, high blood pressure, or a history of blood clots may benefit.
Anyone seeking a low-hormone alternative: Some people prefer the lower hormone dose or want to avoid estrogen for personal reasons.
When It May Not Be Ideal
People who find it difficult to take pills at the same time daily
Those who want highly predictable menstrual cycles
Individuals needing protection against STIs (additional barrier methods are required)
