Each man’s chest hair pattern is indeed unique, influenced by genetics, hormonal levels, and ethnicity. The distribution and density of chest hair can vary significantly, with some men exhibiting dense coverage across the chest, while others have more localized growth around areas like the sternum or nipples. In the 1960s, researcher L.R. Setty studied chest hair patterns in white males, identifying 15 unique distributions based on hair presence in four main areas:
The sternal region (center and lower part of the breastbone), infraclavicular area (just below the inner part of the collarbone), pectoral region (chest area, including around the nipples), and circumareolar area (directly surrounding the nipples). The most common pattern, observed in 57% of subjects, was the Pecto-Sterno-Infraclavicular (PSI) pattern, where hair covers the chest, breastbone, and area below the collarbone. In contrast, the Circumareolo-Pectoro-Sterno-Infraclavicular (CPSI) pattern, featuring hair in all four areas, was rare, seen in only 0.1% of cases. These findings highlight the diverse and individualized nature of male chest hair patterns.
Hairy chested men are a joy to behold. I wish I was, but alas, I’m genetically indisposed. In fact I’m an abnormality, having a patch of hair on one pec, and about 10 hairs around the other nipple. Looks ridiculous. But I’m ok with it. I’m well developed in other areas.
I only have one thing to say:
A man with hairy chest is a sight to behold…
