Testosterone is the male sex hormone. It also defines the bone density, quality blood circulation, controls insulin levels, and metabolism. Oft-times, a lower level of testosterone can be experienced when men reach approximately at the age of 50s. This happens due to a decrease in the level of testosterone naturally with time.

But, men of younger age also experience a lack of testosterone. There might be numerous reasons for it to take place in the body, like medical issues (chemotherapy, metabolic disorders), history of harmful synthetic substance overdose, excessive estrogen, and other lifestyle and medical choices.

How to diagnose lower testosterone levels?

Lack of sex drive -- Testosterone is a prime factor for sexual desires. Low sex drive (libido) eventually occurs with age, but early lethargic sexual behaviour is an indication of the lower level of testosterone.

Erectile Dysfunction (ED) – Testosterone helps in proper blood flow in the penile tissues, which helps in erection. Erectile dysfunction is a condition where a man finds it hard to have a correct and more prolonged erection. The lower level of testosterone leads to the deficient functioning of the penis.

Reduction in quality and volume of semen – Substandard levels of testosterone reduces the quality and quantity of the sperm. It happens due to an imbalanced hormonal reach in the testicles.

A decrease in Muscle Mass and Increased Body Fat – the Reduced level of testosterone decrease the amount of muscle mass as well. The capacity to create new muscle fibers and tissues are lowered in a person with low testosterone as compared to someone with the proper hormonal flow.

Decrease in Bone Density -- Decrease in the level of testosterone leads to thinning of bones as it doesn’t supply an adequate amount of nutrition that our bones require to grow. Testosterone levels are the deciding factor in making or breaking the volume of our skeletal system, and the lack of it makes our bones vulnerable to fractures.

Reduced Productivity Levels – Lack of testosterone causes a man’s body to be less productive due to lack of energy. The desire to work hard moderately depreciates as the days pass by.

Symptoms of depression, Irritability, and Mood Swings – Testosterone also helps in stabilizing and mind, and a reduced level of testosterone always increases our anxiety levels. This switches our negative mode on, and most often, we are sluggish and curse our state of life, thus leading to depression and mood swings.
