Hair loss on the ankles in men can be a sign of low testosterone levels, as testosterone plays a role in the growth and maintenance of body hair. According to the study 1, testosterone deficiency in males is associated with a range of symptoms, including decreased body hair. The normal total testosterone range for adult men is 300 to 800 ng/dL, and levels below this range may indicate hypogonadism, a condition characterized by low testosterone production. Some key points to consider include:
- Testosterone replacement therapy may be considered for men with low testosterone levels, particularly those with symptoms such as decreased energy, libido, and body hair.
- The diagnosis of hypogonadism typically involves measuring morning total testosterone concentration, as well as free testosterone level by equilibrium dialysis and sex hormone-binding globulin level in patients with obesity.
- Treatment with testosterone-replacement therapy should be considered when the morning free testosterone by equilibrium dialysis is frankly low on at least 2 separate assessments, and the hypogonadism workup has been completed to rule out an etiology of hypogonadism unrelated to obesity, as stated in the study 1. It is essential to consult a healthcare provider if you notice hair loss on your ankles, especially if accompanied by other symptoms such as decreased energy, libido, or muscle mass, to determine the underlying cause and appropriate treatment.
From the Research
Signs of Hypogonadism in Men
- Low serum testosterone levels can lead to various symptoms, including changes in physical characteristics
- One possible sign of hypogonadism in men is the lack of hair on the ankles, although this is not explicitly mentioned in the provided studies 2, 3, 4, 5, 6
Relationship Between Testosterone and Hair Growth
- Testosterone plays a role in the development of secondary sex characteristics, including hair growth 4
- However, the specific relationship between testosterone levels and hair growth on the ankles is not discussed in the provided studies
