part_of starts_at ends_at genital tubercle of female urethral fold urethral fold of female anatomical_structure EMAPA:30927 The urethral fold of female (TS:20-TS:27) is the mesenchyme adjacent to the epithelium of phallic urethra that is thought to fuse during internalization of the urethra in males, however whether or not this mesenchyme fuses is unclear. Present in both males and females from E12.5 (Suzuki et al., 2002). Part of the genital tubercle of male/female, part of the urethra of male/female and part of the phallic urethra of male/female. As the genital tubercle becomes the penis/clitoris, the urethral folds become part of the penile/clitoral urethra. Absent after internalisation of the urethra in postnatal males. Absent from postnatal females. TS20 TS27
