Hirsutism or central. It can be caused by increased levels of androgen hormones. The amount and location of the hair is measured by a Ferriman-Gallwey score. It is different than hypertrichosis, which is excessive hair growth anywhere on the body. Treatments may include birth control pills that contain estrogen and progestin, antiandrogens, or insulin sensitizers. Hirsutism affects between 5–15% of all women across all ethnic backgrounds.

Hirsutism affects members of either sex, since rising androgen levels can cause excessive
Muscular evolution in humans defender and hunter. An increase in running as a hunting and survival activity was perhaps fundamental to this development While there is no proof that modern humans have become physically weaker than past generations of humans, inferences from such things as bone robusticity and long bone cortical thickness can be made as a representation of physical strength. Taking such factors into account, there has been a rapid decrease in overall robusticity in those populations that take to sedentism. For instance, bone shaft thickness since the 17th and 18th centuries have decreased in the United States, indicating a less physically stressful
