What is the difference between estrogen and testosterone?

Answer 1

Chemically estriadol and testosterone are remarkably similar, differing only in a methyl group and a carbonyl group. In function however they are responsible for every difference seen between males and females.

Testosterone is involved in:

Greater bone density

Larger organ size

Higher muscle mass

Thicker hair growth

Wider shoulder bones and rib cage

Larger voice box (thus deeper voice)

Development of male sexual organs

Aggression and dominance

Estrogen is involved in:

Breast development

Nurturing/maternal behavior

Development of female sexual organs

Increase in fat tissue, particularly around the thighs, hips and breasts

Decelerated height growth

Reduced muscle mass

Wider pelvic bone

Growth of the uterine lining

In pregnancy, suppressed ovulation

Water retentions

Answer 2

Testosterone is a hormone in men (although women do have some). Causes puberty in males i.e growth, genital development, muscle development, change in voice. Also in charge of arousal.

Estrogen is a hormone in women (although men do have some). Causes puberty in women i.e. development of breasts, pubic hair etc. Causes development of ovaries etc
