Androgens are sex hormones Hormones can be thought of as chemical messengers. Testosterone The major sex hormone in men is testosterone.

Ideally, a fasting blood test should be taken in the morning to detect the body's peak release of testosterone. Testosterone levels should be measured on two separate mornings. The pituitary hormone levels should also be measured other tests — may be required to determine if testosterone deficiency is due to another underlying medical condition.

Semen analysis will help to determine the potential fertility of men with androgen deficiency.
