# The Internet Is Suddenly Talking About 'Progesterone Sensitivity' During Hormone Therapy. Here's What to Know
A viral conversation about "progesterone sensitivity" has spread across social media, with some users claiming that progesterone in hormone replacement therapy (HRT) causes negative side effects. Parents considering or using HRT, or managing teenage children on hormonal treatments, deserve accurate information about this claim.
Progesterone sensitivity is not an established medical diagnosis. The term refers to an anecdotal idea that some people experience heightened reactions to progesterone, a hormone used in birth control, menopause treatment, and gender-affirming care. These claimed reactions include mood changes, bloating, fatigue, and anxiety.
Medical evidence does not support progesterone as uniquely problematic compared to other hormones. Dr. research shows that progesterone can cause side effects, but these effects vary widely among individuals. Some people tolerate it well. Others experience discomfort. This variation is normal with any hormone therapy.
The American College of Obstetricians and Gynecologists (ACOG) notes that hormone therapy side effects depend on dosage, delivery method (pill, patch, injection), timing, and individual biology. A parent or young person experiencing side effects should work with their prescribing doctor to adjust dosage or try alternative formulations, not assume progesterone itself is the culprit.
Social media posts often lack context about the difference between progestin (synthetic progesterone in many medications) and bioidentical progesterone (closer to the body's natural hormone). These compounds affect people differently. Some patients find bioidentical options more tolerable.
If you're considering hormone therapy for yourself or your child, start by discussing your full medical history with your prescriber. Be specific about any side effects. Ask about alternative delivery methods or
