Has the Mystery of the Prostate Orgasm Been Solved?

Updated | An elderly man encountered so much stimulation from a pricey sex toy, it led him to have nonstop prostate orgasms. According to a recent review paper, the unnamed man induced the orgasm by using a butt plug—a toy specifically designed to be inserted in the rectum.

Although the 63-year-old man is featured in the published paper, his experience is just one piece of the story. Rather, the author of the literature explores what is known in the scientific world about prostate orgasms, concluding that there's a lot more to be discovered.

"The scientific study of orgasm has always been challenging," study author Roy Jerome Levin, a researcher at the University of Sheffield, in the U.K., wrote in his paper published in the journal Clinical Anatomy. "Those induced by prostate stimulation have been ignored. We have just started the journey on its discovery road."

There's very limited research to work with, Levin notes, Men's Health reports. So, he relies on personal accounts such as the previously mentioned man's to further understand the mysterious topic.

The man with extreme orgasms was previously healthy, according to Gizmodo. He reportedly purchased the butt plug in order to help ease an infection. However, he quickly realized that he was able to achieve intense sexual pleasure with the toy. Fortunately, the infection went away, but his orgasms—which were felt throughout various areas of his body, including his penis—persisted. Eventually, he became so aroused that he didn't even need to use the toy anymore to achieve an orgasm. Simply lying down was enough to get him going, which is when the trouble began, Gizmodo reports.

"This subject found that whilst the orgasms were extremely enjoyable at the time, he could easily spend too much time experiencing them. Further, he had an old neck injury which flared up in association with some neck spasm at orgasm whilst lying prone. It has proved difficult to stop experiencing these orgasms and 'unwire' himself back to normal," Levin wrote in his published paper.

The prostate is a gland located between the bladder and the penis. Part of the reproductive system, the prostate secretes prostate fluid, an essential component of semen, and contains enzymes, zinc and citric acid. When it comes to orgasms, the prostate has been most commonly of interest for its role in sexual dysfunction; often, men who are treated for prostate cancer may face such difficulties.

Although the man eventually stopped having the random orgasms, it still remains a mystery how they started in the first place. Unfortunately, due to the lack of scientific data, it's difficult to pinpoint what occurred and how his brain may have been "rewired." Levin hopes more researchers will dedicate their time to understanding the prostate orgasm.

"Why, for an obvious example, have we still not had any brain imaging of prostate-stimulated orgasms so that we can compare them with penile orgasms?" he wrote. "Who will lead the challenge?"
