When you have this signal that makes everything open up and fill and engorge, you have the erection. When we don’t have an erection, blood is flowing in and out down there, but it’s going in and out, it’s not a high flow state. The blood rushes in to the point where it actually opens the blood vessels and squishes them against the walls of the chambers of the penis so much so that the veins that would normally drain the blood back out get pinched off. That signal is usually initiated by the brain, some stimulating senses - sight, sound, and touch - cause a message to go down the spine, and then the nerves from the spine go to the penis and they release a signal, nitric oxide, which then triggers all of those blood vessels in the penis to open up and allow lots of blood to rush in. The reason that all happens begins with a signal from nerves. An erection is when the blood can no longer expand the penis, it can just make it stiffer and stiffer, and then at some point no more can go in and it can’t get out. Hydraulic meaning fluid moving in or out of something, and in this case the fluid is blood.īlood rushes into the penis and then it gets trapped there, and that’s an erection. But it can be simplified down as what I would call a hydraulic event. You have to have the brain, you have to have the heart, you have to have the circulatory system, hormones, all of these different things come into play. Aaron Spitz: An erection is kind of a convergence of a lot of complex body systems. Aimee: My first question is what makes an erection happen?ĭr.
I think there’s sort of a season for everything, and this was the season for me to put this book together.ĭr. It was something I had been toying around but didn’t really have a lot of solid direction on, but then the timing was right. It was really born over a dinner conversation. After a very nice dinner meeting with an agent and further discussion, we realized that we really had a great opportunity here. Aaron Spitz: After having gone on television for several years and sharing information about relatively taboo topics in a way that was demystifying but also in a way that was really accessible, I was approached with the suggestion of putting a book together on the topic. Aimee: Why did you write The Penis Book?ĭr. I really enjoy the opportunity to get the word out on this rather hidden topic.ĭr. I also have a book out called The Penis Book, surprisingly. I’ve had a lot of great opportunities to share expertise in this area with a large audience through appearances on television and also most recently in the documentary The Game Changers. I’ve been in practice for about 20 years. Aaron Spitz: I specialize in male sexual function. How are you? Would you tell us about yourself?ĭr.
If you have a penis or know someone who has a penis, this is the interview for you.ĭr. He’s not only a urologist, he’s also the author of The Penis Book.
