Does progesterone increase testosterone?

Progesterone is an important hormone that plays a crucial role in the female reproductive system. It helps prepare the body for pregnancy and is involved in maintaining pregnancy. Testosterone is the main male sex hormone, though females also produce small amounts. There is some evidence that progesterone can influence testosterone levels.
In females, progesterone levels fluctuate through the menstrual cycle along with estrogen. After ovulation occurs, progesterone levels rise and help prepare the uterus for possible implantation of a fertilized egg. If pregnancy occurs, progesterone helps support the pregnancy in early stages until the placenta is fully formed and produces its own progesterone.

In summary:

Natural progesterone seems to lower, not increase, testosterone in females. But synthetic progestins may potentially increase testosterone levels, depending on the type.

More research is still needed to clarify progesterone's complex interactions with testosterone in females. Tracking an individual's hormone levels over time can help determine that person's unique hormonal responses.
