What Could Cause the Absence of Armpit Hair Despite Having Pubic Hair, and Is It Related to Testosterone Levels?

After puberty, hormones like testosterone help grow body hair. However, not all hair follicles are the same. The follicles in the pubic area often need a lower amount of hormones to start growing hair, while the armpit follicles might need a bit more sensitivity to these hormones. This means that even if testosterone levels are normal, some men may grow pubic hair but have little or no armpit hair because the hair in the armpit does not respond as strongly. Genetics also play a role, as your body might simply be more or less sensitive in certain areas. Other factors like the way your cells use and react to hormones (known as androgen receptor sensitivity) can influence this too. In most cases, this difference doesn’t mean that there is a problem with your testosterone levels. Instead, it is just a natural variation in how your body develops hair. If there are concerns about hormonal balance or other related issues, speaking with a doctor can help clarify the underlying reasons.
