I heard that the spermatozoid containing the Y chromosome is much weaker than the one carrying the X chromosome and as a consequence the acidity can kill most of the Y spermatozoid. On the other hand, the Y spermatozoid is much faster than the X and if the vagina is alkaline the Y spermatozoid has more chance.
