[QUOTE="Beefy, post: 43599, member: 57"] My basic answer is "i dont know!" Are you suggesting that some females have selective neutrophils that attack most of the spermatazoa of one sex? they are supposed to be nondiscriminating. As far as pH goes , in general, it should be neutral in young females and then be more acidic after maturity. if it were either extreme i would think it would kill off all the spermatazoa, so anything in the range of 4-10, at least in my theory, would still give you a 50:50 chance. To get more statistical on you, if you have a 50:50 chance to begin with, and then indiscriminate neutrophils attack invading cells at random, its basically a crapshoot as to which lucky spermatozoa makes it to the egg first. i have definitely noticed some cows and mares tend to have more of one sex than others but i think its just happenstance. It would be interesting to hear Dun's and Vicki the Vet's thoughts on this subject. [/QUOTE]
