Shape of nulliparous cervical canal is:

B i.e. Transverse - Under section 375 IPC, sexual intercourse by a man (of any age) is rape, if it is done with his wife who is <15 years of age and with anyother girl who is < 16 years of age even with her consent (statutory rape). - Stautory rape is establishing sexual relation with a person who is under age for providing consent for the actg. Edmund Locard's principle (theory) of exchange states that when any two objects come in contact there is always transfer of material from each object on to the otherQ. Therefore, presence of thick smegma under prepuce & corona glandes in penis (in accused) and absence of smegma, semen & blood in genitalia/cloth with absence of signs of trauma (like abrasion) in body & genitalia (in victim) suggest innocence. Glaister Keene rods may be used to determine degree of rupture of hymen & whether the rupture is recent or oldQ. Section 228A, IPC prohibits disclosure of identity of the rape victimQ. Most impoant sign of defloration is ruptured hymen, which occurs posterolateral (4/8 or 5/7' Oclock) > posterior (6' Oclock) in virginsQ. However hymen can rupture by sanitary tampons, masturbation, horse riding etcQ. - In nulliparous, cervical opening is circular and cervical canal is flattened transverselyQ.
