Surest sign of virginity is: 
Select and explain. 
A. Intact hymen, B. Convex uterine wall, C. Non pendulous breast, D. None of the above
D: None of the above
Answer: D: None of the above 
Explanation: Ans: d (None of these) Ref: Reddy, 21st ed, p. 330No single sign can be considered as the surest sign of virginity.The principal signs of virginity are:1. An intact hymen2. Normal condition of the fourchette and posterior commissure3. Narrow vagina with rugose wallsThese signs taken together may be regarded as evidence of virginity but taken singly they cannot be so regarded. Most of us would have gone for option A (intact hymen), but any doubt remaining can be settled with this line from Reddy:"Cases have been recorded of women having sexual relations, prostitutes and even pregnant women in whom the hymen was intact."
