Let me clear some points which may be ask in Exam :-
1) Presence and absence of Hymen is not a "indicative of Virginity or sexual experience"
2) At least 60% of total sperm must have normal shape and size
And 40% of them i.e 40% of 60% i.e 24% of total total sperm must have vigorous motility for normal fertility .

3) Absence of menstrual cycle " may be" indicative of pregnancy not always .
