As of 2015, a systematic review of 20 studies, of up to 15,521 men, who were measured by health professionals rather than themselves, concluded that the average length of an erect human penis is 13.12 cm (5.17 in), while the average circumference of an erect human penis is 11.66 cm (4.59 in). [2] A 1996 study of flaccid length found a mean of 8 ...

For medical use, see body shape. Bust/waist/hip measurements (informally called 'body measurements' or ′vital statistics′) are a common method of specifying clothing sizes. They match the three inflection points of the female body shape. In human body measurement, these three sizes are the circumferences of the bust, waist and hips; usually ...
Cytoplasmic male sterility (CMS) is mostly found in angiosperms and has been identified in more than 140 angiosperm species. [2] CMS has also been identified in one animal species so far, Physa acuta, a fresh water snail. [3] There is strong evidence for gynodioecy and CMS to be a transitionary step between hermaphrodites and separated sexes. [4]
