A new scientific study is changing what we thought we knew about male sexual anatomy.
After years of research, scientists in Spain have finally pinpointed the male “G-spot,” revealing that this erogenous zone sits nowhere near where many expected. They laid out their findings in a study published in the journal Andrology.
So where exactly is this zone — known for its role in producing intense physical sensation when stimulated? It lives in a little-known area called the frenular delta, a triangular patch on the underside of the penis where the head connects to the shaft — a zone so overlooked it has largely been left out of sexual health textbooks, according to New Scientist.
According to the study, carried out by researchers at the University of Santiago de Compostela in Spain, this region is densely packed with partially overlapping nerve branches from both the perineal and dorsal systems, along with notably high concentrations of nerve clusters and pleasure receptors.
In plain terms, the frenular delta is capable of producing “intensely pleasurable and highly specialized sensations,” as the paper describes.
While this area may feel self-evident to many sexually active males, the researchers’ work formally validates it as a genuine center of sexual sensation — something science had never officially confirmed before.
By mapping this zone, scientists have shed light on a region that had quietly been overlooked in sexual medicine for decades. For years, the prostate had been regarded as the primary driver of male orgasms, yet no one had properly placed the frenular delta on the anatomical map — until now.
To bring this hidden anatomy into focus, the research team analyzed penile tissue samples taken from 30 fetuses, alongside samples from 14 adult males who had donated their bodies to science after death. They studied cross sections of the tissue under a microscope to map exactly where the nerve endings clustered.
By examining these slices from multiple angles, they assembled the most thorough picture yet of where these receptors actually sit.
They discovered that this region contained more nerve bundles and sensitive receptor clusters than any other area — with as many as 17 packed into a small area in certain cases.
Among the structures found here are Krause corpuscles, which are thought to pick up the subtle vibrations that travel through the genitals during skin-to-skin contact, sending signals through the body.
This made the frenular delta far more nerve-rich than the penis head — or glans — which had long been considered the top stimulation zone.
“It is one of the most pleasurable spots for male sexual stimulation,” said Eric Chung of the University of Queensland in Australia, who was not part of the study, speaking to New Scientist about the frenular delta.
The research carries real weight, given that the concept of a male “G-spot” has remained one of the biggest blind spots in sexual medicine and urology — largely unexamined and poorly understood.
Far more scientific focus has historically gone toward the female equivalent, which has been studied extensively by both researchers and partners seeking to understand female pleasure.
Despite various studies affirming its existence, the broader expert consensus is that the female G-spot is actually made up of five distinct erotic regions within the vagina.
“We suggest the current term ‘G-spot’ is misleading and therefore inappropriate,” wrote Dr. Irwin Goldstein, editor-in-chief of the Sexual Medicine Review journal, along with his colleagues, in a 2022 editorial.
