What is progesterone?
Progesterone is an important hormone that plays a vital role in the female reproductive system and pregnancy. It is mainly produced by the corpus luteum in the ovary during the luteal phase of the menstrual cycle.
Some key facts about progesterone:
- It is a steroid hormone and belongs to the progestogen group.
- Along with estrogen, progesterone is crucial for the regulation of the menstrual cycle and the maintenance of early pregnancy.
- Progesterone levels rise after ovulation, triggering changes in the endometrium to prepare the uterus for possible implantation of a fertilized egg.
- If pregnancy occurs, progesterone levels remain elevated to maintain the endometrium and support the developing embryo.
- If pregnancy does not occur, progesterone levels drop, triggering menstruation.
- Progesterone has other functions like development of mammary glands, regulating body temperature, promoting uterine quiescence to prevent preterm labor, and more.
Some key effects of progesterone on the body:
- Causes buildup and vascularization of the endometrium.
- Inhibits muscle contractions in the uterus to prevent early labor.
- Prepares and maintains the mammary glands for milk production.
- Contributes to development of secondary sex characteristics.
- Regulates the monthly cycle and promotes embryo implantation.
- Maintains pregnancy by supporting the developing placenta and fetus.
Progesterone levels vary throughout the menstrual cycle:
- Levels are low during the follicular phase.
- Levels surge just after ovulation to ~10 ng/ml.
- Levels rise steadily during the luteal phase, peaking at ~25 ng/ml.
- If no pregnancy occurs, levels drop rapidly before menstruation.
Progesterone is available in various pharmaceutical preparations:
- Progesterone pills like Prometrium to supplement natural progesterone levels.
- Progesterone creams and gels for topical application.
- Progesterone injections like Progesterone in Oil (PIO) used in fertility treatments.
- Progesterone intrauterine devices (IUDs) like the Mirena IUD that release progesterone locally.
