Testosterone is one of the hormones needed for sexual development
and is present in both males and females. Testosterone is considered an
androgen, which is a male sex hormone, because it is made in much higher
amounts in men than in women.
Testosterone helps strengthen bones and muscles in both men and
women. In young men, testosterone signals the body to lower the voice, grow
facial hair, and develop sexual characteristics. This hormone is also needed
for sperm production.
