Progesterone is for females as testosterone is for males, and so they say. Well, progesterone does play an important role in fertility, ovulation, and pregnancy in women – but it doesn’t actually end there.
The main role of progesterone in the male body is counterbalancing the effects of estrogen. What’s unknown to most men is that progesterone also serves as testosterone’s precursor.
This actually becomes more important as men age because this is the time when testosterone starts declining and estrogen becomes more dominant.
Do note, however, that whenever estrogen stays elevated, progesterone levels drop – and when this happens, testosterone levels will likewise fall.
Since low progesterone levels limit the availability of testosterone, symptoms like hair loss, low libido, fatigue, weight gain, and gynecomastia (or man boobs) may manifest.
Depression, bone loss, impotence, erectile dysfunction, and muscle loss may also occur. Men with low progesterone levels are at risk of developing serious conditions like prostatitis and prostate cancer.
