Progesterone - Hormone Harmony Clinic

What is progesterone?

Progesterone is an important sex hormone involved in regulating the menstrual cycle, ovulation, and reproductive development. It also plays a key role in maintaining pregnancy and helps regulate mood, skin health, and libido.

What are some key functions of progesterone?

• Prepares the lining of the uterus (endometrium) for potential embryo implantation
• Regulates the menstrual cycle and assists with ovulation - the egg release from the ovary
• Helps support a pregnancy by thickening the uterine lining, reducing uterine contractions, and preventing the early shedding of the endometrium
• Works to balance estrogen levels in the body
• Supports bone health and helps prevent osteoporosis
• Plays a role in skin health and collagen production
• Impacts mood, behavior, and sex drive

Essentially, progesterone works closely and synergistically with estrogen to regulate the reproductive cycle before and during pregnancy.

Where does progesterone come from?

In women, progesterone is mainly produced by the ovaries and the placenta during pregnancy. The ovaries make progesterone after ovulation occurs in order to transition the uterine lining and body temperature for pregnancy.

If pregnancy does not occur, progesterone levels will decrease, triggering menstruation. Then the cycle starts again with rising estrogen levels.

What causes low progesterone?

Some common causes of low progesterone include:

• Hormonal imbalances
• Thyroid disorders
• Early menopause
• Excessive exercise
• Chronic stress

Symptoms of low progesterone can include menstrual cycle issues like spotting before periods, heavy/painful periods, missed periods, and infertility. Mood issues, hot flashes, fatigue, trouble sleeping, and changes in libido are also possible.
