Note however that a 2021 study found that slight changes in measurement placement definition can recategorise up to 40% of women into different body shapes, meaning cross-research comparisons may be flawed unless the exact measurement definitions are used. [32] [33] Several similar classifications of women's body shape exist. These include: [34]
It has been proposed by scientists that the evolutionary reason for the female body shape is due in part to this sexual selection.Sex-typical body shapes (a man's muscular physique and a woman's hourglass figure) are an outcome of evolutionary adaptation for reproductive fitness because they convey information about gene quality, health and fertility, which are important elements for mate ...

In human body measurement, these three sizes are the circumferences of the bust, waist and hips; usually rendered as xx–yy–zz in inches, or centimeters. The three sizes are used mostly in fashion , and almost exclusively in reference to women, [ 1 ] who, compared to men, are more likely to have a narrow waist relative to their hips.
The study — published Aug. 14 in the journal Nature Aging — analyzed over 135,000 types of molecules affected by aging in 108 adults aged 25 to 75. These molecules were tracked for age-related ...
The human female cervix has been documented anatomically since at least the time of Hippocrates, over 2,000 years ago. The cervix is approximately 4 cm long with a diameter of approximately 3 cm and tends to be described as a cylindrical shape, although the front and back walls of the cervix are contiguous. [1]
