Grok answer:
The phenomenon often referred to as "old man smell" isn't exclusive to men. It's a body odor change that can occur with aging in both men and women, driven by similar biological processes. As people age, hormonal shifts, particularly a decline in estrogen and testosterone, alter skin gland activity, leading to changes in sebum and sweat composition. A key factor is the increased production of 2-nonenal, a volatile compound formed when omega-7 fatty acids in skin oils oxidize. This compound, described as having a greasy or musty odor, was identified in studies like one from the Journal of Investigative Dermatology (2001), which found 2-nonenal levels rise significantly in people over 40, regardless of gender.
Lifestyle, diet, hygiene, and environmental factors also play roles. For example, older adults may use different soaps or have reduced skin cell turnover, which can trap odor-causing bacteria. Women, like men, can experience these changes, though cultural factors—such as women being more likely to use scented products—might mask or alter perceptions of the smell. There's no evidence suggesting women are immune to these aging-related odor shifts; the stereotype of "old man smell" likely stems from social biases rather than biology.
So, yes, older women can have a similar aging-related body odor, though individual variations mean not everyone does, and it’s not always noticeable. If you’re curious about specific cases or mitigation (like diet or hygiene tweaks), let me know!
