The sinovaginal bulb is a transitional structure in the development of female genitalia, and is one of a pair of endodermal outgrowths of the urogenital sinus, which later fuse to form the lower part of the vagina. [1] [2] The lower third of the vagina is derived from the urogenital sinus. [3]
The hymen is formed from the same tissue as the sinovaginal bulb. [1]
