After years of investigation, researchers in Spain have identified what could be described as a male equivalent of the “G-spot,” revealing that this highly sensitive area is located somewhere quite unexpected. Their findings were published in the scientific journal Andrology. The region in question is known as the frenular delta—a small, triangular area on the underside of the penis where the glans meets the shaft.

Despite its apparent importance, this zone has historically received little attention in medical literature. According to researchers from the University of Santiago de Compostela, the frenular delta contains a dense network of nerve fibers, including overlapping branches linked to both perineal and dorsal nerve systems. This concentration of nerve endings appears to make it especially responsive to stimulation.

In simpler terms, the study suggests that this area is capable of producing particularly intense and distinct sensations. While many individuals may already recognize its sensitivity through personal experience, the researchers emphasize that their work formally establishes the frenular delta as a key center of sexual responsiveness.

For decades, scientific focus on male sexual pleasure has largely centered on the prostate, often overlooking external anatomical regions. This study shifts that perspective by mapping out a previously underappreciated area of the penis. To do so, the research team analyzed tissue samples from both fetal and adult donors, examining them under a microscope to identify the distribution of nerve endings.

Their analysis revealed that the frenular delta contains a notably high density of sensory structures—sometimes up to 17 nerve bundles clustered within a small space. Among these are Krause corpuscles, specialized receptors believed to detect subtle vibrations generated during physical contact, contributing to sexual sensation.

Interestingly, the findings indicate that this region may be even more densely innervated than the glans itself, which has long been considered the most sensitive part of the penis. Experts not involved in the study, including Eric Chung from the University of Queensland, have described the frenular delta as one of the most responsive areas for male stimulation.

Overall, the research addresses what scientists have described as a longstanding gap in sexual medicine and urology, offering a clearer understanding of male anatomy and sensory function.
