Comments: Progesterone is the new darling of those who study brain chemistry. Research is coming out almost weekly showing how important progesterone is to brain function. Dr. Lee and I started reporting on progesterone and the brain a decade ago. Dr. Lee famously said that if anyone in his family had a brain injury, he would slather them with progesterone cream. You can imagine the derisive letters and phone calls he received from his colleagues for that statement! A few years later a smart ER doctor who saw a lot of head injuries started wondering why brain injuries were worse in men than in women, and was eventually approved to do a study in which brain injury patients were given injections of progesterone when they arrived in the ER. His research showed that those who received the progesterone did significantly better than those who didn’t. Similar studies have shown the same result.

Around the same time, researchers discovered that progesterone was a key component of the myelin sheath that protects or insulates the nerves—so important in fact that progesterone is made in the myelin sheath. Other research showed that progesterone stimulates the brain’s GABA receptors, those feel-good, calming neurotransmitters.
