If you’re constantly flying at half-mast in the bedroom, you’re not alone. Penis problems are more common than you think. Nearly 30 million Americans suffer from erectile dysfunction. And no, not all of them are your grandfather’s age.
One in four men affected are under the age of 40. According to a study published in Proceedings of the National Academy of Sciences, nitric oxide is responsible for relaxing the smooth muscle so blood can fill the peen. After that initial release of NO, your body releases more chemicals that keep you hard and feeling good all night long.
According to a new study by co-author Dr. Daniel Adekunbi of King’s College London in the United Kingdom and colleagues, increasing activity of the hormone kisspeptin in a specific area of the brain has the potential to reduce anxiety in men and boost sexual behavior.
Kisspeptin, a hormone produced by a section of the brain called the hypothalamus, interacts with receptors in the pituitary gland, which is connected to the bottom of the hypothalamus. This prompts a signaling cascade that fuels the production of the sex hormones testosterone and estradiol. The findings are being presented at the Society for Endocrinology Annual Conference, held in Harrogate, U.K.
