[QUOTE="Katie, post: 530465, member: 8131"] I'm not sure if this will help or not, but this info is true in humans not sure if the same applies in cows. The ph in the females reproductive tract has an affect on sex of offspring. For example sperm for a boy favers a alkaline environment so female sperm would not survive and female sperm favor a more acid environment so male sperm would die. Also timing of sex helps male sperm die sooner but move faster so close to ovulation you would be more likely to have a boy farther a girl because the girl sperm live longer but move slower. [/QUOTE]
