![]() Mammary glands do not contain muscle tissue. Breasts įemales have enlarged breasts due to functional mammary glands, which develop from puberty onward due to the effects of estrogen. Prominent muscles of the body include the latissimus dorsi, trapezius, pectoral muscles (muscles critical for a strong erect posture) as well as biceps and triceps in the arms and quadriceps and hamstrings in the thighs. On average, men have around 10 times more testosterone than women. Testosterone helps build and maintain muscles through exercise. Males generally deposit fat around waists and abdomens (producing an "apple shape"). Males have less subcutaneous fat in their faces due to the effects of testosterone testosterone also reduces fat by aiding fast metabolism. Body fat percentage guidelines are higher for females, as this may serve as an energy reserve for pregnancy. around the belly instead of buttocks and thighs.Įstrogen increases fat storage in the body, which results in more fat stored in the female body. Hormonal and genetic factors may produce male-like distribution of fat in women i.e. Thus females generally have relatively narrow waists and large buttocks, and this along with wide hips make for a wider hip section and a lower waist–hip ratio compared to men. Later fat is stored in the belly, similar to men. When females reach menopause and the estrogen produced by ovaries declines, fat migrates from their buttocks, hips and thighs to their waists.

Both male and female hormones are present in the human body, and though only one of them is predominant in an adult, the other hormone has effects on body shape to some extent. However, not all females adhere to this stereotypical pattern of secondary sex characteristics. After puberty, hips are generally wider than shoulders. The upper limb in females have an outward angulation (carrying angle) at elbow level to accommodate the wider pelvis. This sometimes affects their walking style, resulting in hip sway. The sacrum in females is shorter and wider, and also directed more toward the rear (see image). ![]() Because the female pelvis is flatter, more rounded and proportionally larger, the head of the fetus may pass during childbirth. Hence females generally have wider hips, permitting childbirth. ![]() Widening of the hip bones occurs as part of the female pubertal process, and estrogens (the predominant sex hormones in females) cause a widening of the pelvis as a part of sexual differentiation. ![]()
