Progesterone is a hormone that plays an important role in the menstrual cycle and pregnancy. It is secreted by the ovaries and helps prepare the uterus for pregnancy. Testosterone is a sex hormone that is important for sexual development and function in both men and women.
The relationship between progesterone and testosterone is complex. Here is an overview:
- In females, progesterone and testosterone levels fluctuate during the menstrual cycle. In the first half of the cycle when a follicle matures and estrogen levels rise, testosterone levels also increase mildly. After ovulation occurs, the corpus luteum secretes more progesterone which can suppress testosterone production.
- During pregnancy, high levels of progesterone from the placenta and ovaries can also suppress testosterone levels in women.
- In menopause when progesterone levels decline, some research indicates that testosterone levels may increase mildly in some women. However, more research is still needed on this.
- In men, there is some evidence that higher progesterone levels may be linked to reduced testosterone production by the testes. One small study found that men treated with a synthetic progestin had lowered testosterone levels. However, more research is still needed.
So in summary:
- In females, fluctuating progesterone levels during the menstrual cycle and high levels during pregnancy can suppress testosterone production.
- In menopausal women and men, there is limited evidence that higher progesterone may be linked to lower testosterone. However, more research is still needed to confirm this.
The interaction between progesterone and testosterone is bi-directional. This means that high or low levels of one hormone can affect production of the other hormone. Maintaining healthy balances of both progesterone and testosterone is important.
If you have concerns about your hormone levels, symptoms of high or low testosterone or progesterone, or difficulty getting pregnant,
consult with your doctor. They can check your hormone levels and help diagnose and treat any imbalances or underlying conditions. A specialist like an
endocrinologist or fertility doctor may be needed.
