description: "The genital tubercle of female (GT) (syn: clitoris anlage) is a medial swelling seen at the level of the hind limb buds, adjacent to the cloaca and posterior/caudal to the urogenital sinus (UGS). The genital tubercle is separated into male and female, therefore you must know the sex of the embryo. At TS:20, the genital tubercle of female is comprised of genital tubercle mesenchyme of female, urethral plate epithelium of female, skin of genital tubercle of female, the urogenital membrane of female, and developing vasculature of female genital tubercle. The urethral plate epithelium and skin together, where they are in direct contact, are known as the urogenital membrane. After TS:20, the genital tubercle becomes further subdivided. At TS:21 the genital tubercle of female is subdivided into distal genital tubercle of female (TS:21-TS:22) (syn: early glans of female), proximal genital tubercle of female (TS:21-TS:22) and preputial swelling of female. Also contains phallic urethra of female and nerve of female genital tubercle (from TS:22). From TS:23, it is subdivided into glans of female genital tubercle (located distally) and preputial swelling of female (located proximally and becoming prepuce of female at TS:24). Will become the clitoris at TS:25."
