Testosterone is a steroid hormone from the androgen group and is found in humans and other vertebrates. In humans and other mammals, testosterone is secreted primarily by the testicles of males and, to a lesser extent, the ovaries of females. Small amounts are also secreted by the adrenal glands. It is the principal male sex hormone and an anabolic steroid.
In men, testosterone plays a key role in the development of male reproductive tissues such as the testis and prostate as well as promoting secondary sexual characteristics such as increased muscle, bone mass, and the growth of body hair. In addition, testosterone is essential for health and well-being as well as the prevention of osteoporosis.
Actually, the pelvis is composed of several bones: the sacrum and coccyx and the three proper pelvic bones the Ischium, ileum and pubis. The ileum sichium and pubis are separated during childhood but fuse during puberty. A surge of estrogen during puberty closes the epiphysial plates of all bone in the female.
The shape of the human pelvis is sexually dimorphic, the female is wider by bone configuration rather than by "growth." The so-called "widening" of the female pelvis during late puberty is mostly due to an increase in subcutaneous fat.
The growth of pubic hair is common in both males and females during puberty.
