In this short video, Dr. Anne Truong, a medical doctor and sexual health specialist focusing on erectile dysfunction, explains that the majority of scientific research on the refractory period—the recovery time after orgasm—has been conducted in rats, leaving a surprisingly thin evidence base for humans. She notes that current medical understanding relies more on knowledge of brain inhibition pathways and sexual neurochemistry than on direct human trials. Dr. Truong outlines that the refractory period can be lengthened by specific neurochemical mechanisms and highlights common, modifiable factors that individuals can address to influence its duration.

I know, surprisingly, right? Most of the studies actually come from rats, believe it or not. The human evidence base surrounding the refractory period is surprisingly very thin. Much of what medicine understands today isn't based upon direct observation trials of recovery time, but on what we know about the brain, the inhibition, and the sexual pathways. So today I'm going to break down what actually causes the refractory period to lengthen and the brain chemistry driving it and the most common modifying factors that you can follow. I'm Dr. Anne Truong. I'm a medical doctor. I'm a sexual health specialist. I specialize in erectile dysfunction.
