Regarding body hair, many of the symptoms of low T – loss of libido, inability to focus and others are pretty non-specific — some with some of your symptoms – achne, watery semen. Those can have lots of causes and it’s hard to tell if they come from use of T or not. However, changes in hair growth is good evidence about what is going on with testosterone. Women who have elevated testosterone levels will begin to grow facial hair. Men that have reduced testosterone will generally find facial hair growing more slowly and have to shave less often.
