One of the primary reasons for male HRT is low testosterone levels, also known as hypogonadism. This can lead to symptoms such as fatigue, low libido, decreased muscle mass, and mood swings.

Similar to menopause in women, men may experience a decline in testosterone levels with age, leading to symptoms like fatigue, irritability, and diminished sexual function.

Testosterone plays a crucial role in maintaining sexual function, and low levels may contribute to erectile dysfunction. HRT can help improve libido and sexual performance.

Low testosterone levels can contribute to feelings of fatigue and low energy. HRT aims to restore hormonal balance, potentially improving overall energy levels.

Hormonal imbalances, including low testosterone, may be associated with mood disorders. HRT can be considered to alleviate symptoms of depression and mood swings.

Some studies suggest a link between testosterone levels and cognitive function. HRT may have cognitive benefits, including improved concentration and memory.
