Does a man's inability to grow facial hair affect his sexual function?

Whether a male's lack of beard growth affects sexual function needs to be analyzed according to specific circumstances.

1. Yes

Under normal circumstances, after males enter puberty, beard growth becomes one of the secondary sexual characteristics. If excessive mental stress, chronic sleep deprivation, or poor diet lead to endocrine disorders, this may result in reduced secretion of androgens. In such cases, lack of beard growth may occur. Since androgens are also important for male sexual function, their reduction can negatively affect sexual performance, leading to symptoms such as decreased libido, erectile dysfunction, premature ejaculation, or weak and unstable erections.

2. No

If the absence of beard growth is due to excessive sebum production combined with poor hygiene that causes follicular blockage, preventing normal hair growth, it generally does not adversely affect sexual function. However, this condition may lead to folliculitis or other skin issues such as boils.

In addition, decreased sexual function in males could also stem from prolonged psychological distress or medical conditions such as arteriosclerosis or hyperthyroidism.
