Dimensions of female therian genital variation. (A) Scheme showing the naming of parts used in the present paper. (B) The variation in the number and nature of orifices can be classified by the relative position of the urethra joining the reproductive tract. (C) The variation in the relation of clitoral apparatus to the urethral and vaginal openings. The two patterns on the left show clitoris associated with UGS; either being traversed by the UGS, or separate. The two patterns on the right show cases in which urethra opens in separate orifice from the vaginal segment, and the clitoris is either ventral to, or traversed by the urethra.
