Female form

Female body shape or female figure is the cumulative product of a woman's skeletal structure and the quantity and distribution of muscle and fat on the body.

As with most physical traits, there is a wide range of normality of female body shapes.

Attention has been focused on the female body as a source of aesthetic pleasure, sexual attraction, fertility, and reproduction in most human societies. There are, and have been, wide differences in what should be considered an ideal or preferred body shape, both for attractiveness and for health reasons.

Women's bodies occur in a range of shapes. Female figures are typically narrower at the waist than at the bust and hips. The bust, waist, and hips are called inflection points, and the ratios of their circumferences are used to define basic body shapes.

Estrogens have a significant impact on a female's body shape. They are produced in both men and women, but their levels are significantly higher in women, especially in those of reproductive age. Besides other functions, estrogens promote the development of female secondary sexual characteristics, such as breasts and hips. As a result of estrogens, during puberty, girls develop breasts and their hips widen. Working against estrogen, the presence of testosterone in a pubescent female inhibits breast development and promotes muscle development.

Estrogen levels also rise significantly during pregnancy. A number of other changes typically occur during pregnancy, including enlargement and increased firmness of the breasts, mainly due to hypertrophy of the mammary gland in response to the hormone prolactin. The size of the nipples may increase noticeably. These changes may continue during breastfeeding. Breasts generally revert to approximately their previous size after pregnancy, although there may be some increased sagging.
