Well you could say progesterone makes men manly enough to get women pregnant. Most of the studies out there suggest progesterone in men has a similar effect to the male hormone testosterone. Like testosterone, progesterone enhances your libido, improves your mood, helps keep your weight down and increases muscle mass, gives you more energy, stronger bones, stronger erections and a whole host of other health benefits. Progesterone also increases levels of testosterone in your body and enhances its effects. At the same time, it reduces estrogen and antagonizes its effects.
It’s no wonder then that progesterone can play a big role in helping you lose those man boobs.
How Does Progesterone Help Get Rid Of Man Boobs?
The role of progesterone has been severely underestimated in men. Depending on the stage of a woman’s menstrual cycle, men can have just as much progesterone in their bodies as women. Most scientific studies have focused on the effects of progesterone on women, and its role in men has been neglected. It’s only recently that scientists have started to realize how important this hormone is in men.
When it comes to determining a man’s masculinity – body fat, muscle mass, libido, sperm count, erections, etc – the latest studies suggest progesterone is just as important as estrogen and testosterone. In fact, progesterone is a precursor to both of these hormones (meaning both estrogen and testosterone are produced from progesterone), so it plays a big role in deciding the levels of these hormones. Where guys with man boobs generally have high estrogen and/or low testosterone, progesterone works, in part, by lowering estrogen, and raising levels of testosterone.
Progesterone Acts With Testosterone
Progesterone has many of its own effects on the body. In men, the studies suggest that progesterone works a lot like testosterone, so much that it can even be considered a second male sex hormone. In a study, published in the book, The Hidden Structure of Interaction, researchers found that progesterone and testosterone levels rise and fall together in weekly and monthly cycles. Both testosterone and progesterone levels rise together in response to increased sexual activity in men.
Progesterone is also the most potent known inhibitor of the enzyme 5-alpha-reductase, which converts testosterone into dihydrotestosterone (DHT). DHT is a known cause of male pattern balding, prostatic hyperplasia, and prostate cancer. By blocking 5-alpha-reductase, progesterone promotes higher levels of testosterone in your body.
Progesterone Antagonizes Estrogen
Not only does progesterone raise levels of and have similar actions to the male hormone testosterone, it also acts against estrogen, much like testosterone does. Progesterone antagonizes the estrogenic effect on your body via multiple different mechanisms. One such mechanism is via regulation of cell metabolism to promote the oxidative pathway. This prevents conversion of the much weaker form of estrogen, estrone, to a more potent form, known as estradiol.
We know for example, that like testosterone, progesterone reduces estrogen-driven cancers like prostate cancer in men, and breast and endometrial cancer in women.
As men age, both their levels of testosterone and progesterone decrease, while estrogen levels increase. When high estrogen levels are unopposed by testosterone and progesterone, it leads to a condition called estrogen dominance. Amid the myriad of different problems, symptoms and conditions caused by estrogen dominance, it is also the single most important cause of gynecomastia (man boobs).
