In a healthy woman who has experienced complete coitus, the hymenis torn or often only stretched. It admits two fingers without pain. In. Fig. 3, tog. 4. Hymen of virgin with vertical slit. (Vi) Hymen with oval opening. (Vj) Fi£-S-Crescentic hymen, (/i) a woman who has borne full-time children, the vaginal orifice is alwaystorn though the fourchette and all behind it may be intact. The remainsof the hymen are known as the carunculae myrtiformes. In addition, thepassage of the childs head may cause tears of the posterior vaginal wall,perineal body, or even anterior wall of rectum. (2.)
