High Quality Content by WIKIPEDIA articles! The human vaginal region has a higher concentration of bacteria than any other part of the body other than the colon. The bacteria of the vaginal flora were discovered by the German gynecologist Albert Döderlein in 1892. Primarily, these bacteria consist of lactobacilli [1], and are collectively referred to as the vaginal flora. The amount and type of bacteria present have significant implications for a woman's overall health. These bacteria and the lactic acid they produce, in combination with fluids secreted during sexual arousal, are greatly responsible for the characteristic scent associated with the vaginal area.
