Progesterone: Role, Uses & Resources

When working with progesterone, a steroid hormone produced by the ovaries, placenta and adrenal glands that prepares the uterus for pregnancy and regulates the menstrual cycle. Also known as the pregnancy hormone, it plays a central role in many reproductive‑health topics. In everyday language, progesterone is the hormone that tells your body, “We’re ready for a baby,” and when it’s not around, the cycle stops. This simple definition sets the stage for everything else you’ll read on this page.

The impact of progesterone doesn’t happen in isolation. It works hand‑in‑hand with estrogen, the primary female sex hormone that together controls the menstrual cycle and supports bone health. When estrogen rises in the first half of the cycle, progesterone spikes after ovulation, creating the perfect environment for a fertilized egg. This partnership is why doctors talk about “estrogen‑progesterone balance” when addressing irregular periods.

Another major arena is hormone replacement therapy, a treatment that adds back estrogen and progesterone to ease menopause symptoms and protect bone density. In menopause, ovarian production of both hormones drops sharply; adding progesterone back can reduce hot flashes, improve sleep, and lower the risk of uterine lining overgrowth when combined with estrogen.

Progesterone also shows up in most forms of contraception, methods that often rely on synthetic progesterone to stop ovulation and thicken cervical mucus. Whether you’re using a birth‑control pill, a hormonal IUD, or an injectable, the progesterone component is the engine that prevents an egg from being released.

Finally, think about menopause, the natural phase when ovarian hormone production, including progesterone, declines dramatically. The drop in progesterone (and estrogen) explains why many people experience night sweats, mood swings, and changes in libido during this time.

These four entities—estrogen, hormone replacement therapy, contraception, and menopause—form the core map around progesterone. Understanding how they link helps you decide whether you need a supplement, a prescription, or simply lifestyle tweaks.
