In a new study published in the professional journal Andrology, researchers from Spain report that they have precisely determined the location of the so-called male G-spot. This G-spot is associated with the frenular delta, a triangular area on the underside of the penis where the glans connects to the shaft of the penis.
According to New Scientist, this is an anatomically poorly described area that has long been omitted from textbooks on sexual health. According to the authors, the frenular delta produces extremely pleasant sensations.
To map this "erogenous map" in detail, the researchers analyzed tissue samples from the penises of 30 fetuses, as well as samples from 14 adult men who donated their bodies to science after death. They examined tissue sections under a microscope from different angles to precisely determine the arrangement of nerve endings.
Based on this, they were able to create the most detailed depiction to date of the location of pleasure receptors. They found that the male G-spot contains more nerve bundles and sensitive receptor clusters than any other part of the penis, with up to 17 bundles concentrated in a very small area in some cases.
Among the structures contributing to these sensations are Krause's corpuscles, which are believed to register subtle vibrations caused by skin friction, thereby transmitting sexual sensations. Due to such a dense nerve network, the frenular delta has proven to be significantly more sensitive than the glans of the penis, which was previously considered the main area for stimulation.
