As far as physical aspect is concerned it is scientifically established that men lose testosterone at 10% a decade after the age of 30 and by the time you are 40 you start feeling the effects of low testosterone.
Testosterone is the principle male hormone and is responsible for giving you your masculine traits and characteristics. It production peaks during adolescence when major body changes take place. It is responsible for your sexual strength, sex drive, muscle and strength gain, bone density, mental alertness and energy levels.
It is also behind the deepening of your voice, growth of beard and torso hair. As such a dip in testosterone leaves little untouched in your male body.
Physically, there are numerous parts of the body that are affected by a decrease in testosterone. Bone density is a big factor. Over 10% of men have osteoporosis, resulting from a lack in bone density. This increases the chance of hip, wrist, and spine fractures, as just a few examples of areas of your body that are affected.
Sexual function is also affected, resulting in difficulty maintaining erection, and weak erections. Muscles lose their strength, and the immune system is weakened.
It's more than just physical, though. If you suffer from Andropause you may have felt your moods change, either dramatically or gradually. Depression is often a common symptom of low testosterone. Along with physical sexual functions that we discussed above, your desire for sex may have decreased as well.
How To Increase Male Sex Drive and Libido
The key to increasing your sex drive and libido is to increase testosterone levels that get depleted with age. Testosterone enhancement is possible through natural means which include
A good diet that is rich in proteins and limited in carbohydrates and moderate in essential fats. (Carbohydrates specially those that consist of simple sugars such as potatoes increase insulin and cortisol levels in your blood which affects testosterone production negatively.)
Regular exercise - You must understand that both lack of physical activity and over training can lead to low testosterone levels. The ideal period to workout is 45-60 minutes in a single routine. Any more than that and your body starts producing Cortisol which inhibits and diminishes testosterone production in your body.
Reduced Stress - Stress is one of the major psychological factor affecting your sex drive and testosterone levels besides negative feelings like guilt, anxiety and depression. A relaxed state of mind is highly important for elevating your sex drive.
Good Sleep - A good sleep is going to help you raise your sex drive substantially.
