What is the role of progestin in hormone therapy?

• A. To increase estrogen production
• B. To reduce bleeding risks in general
• C. To protect the endometrium from hyperplasia when uterus is present.
• D. To prevent hot flashes

Answer: (C)

The essential idea is that progestin’s role in hormone therapy for someone with a uterus is to protect the endometrium from estrogen-driven proliferation. Estrogen can stimulate the lining of the uterus to grow, and with long-term estrogen therapy, this can lead to endometrial hyperplasia and even cancer risk. Adding progestin counteracts that effect, guiding the endometrium through secretory changes and, in many regimens, triggering a withdrawal bleed. This endometrial protection is the main reason progestin is included when the uterus is present. It’s not primarily about increasing estrogen production, reducing bleeding risk in general, or preventing hot flashes—those symptoms are more directly managed by estrogen itself.
