i'm guessing here!!!
but if he has low sperm count, you may want to try hormones when TTC...also, i would "imagine" with a low sperm count, you'd end up with a boy.....the males are stronger swimmers, and when there's not as much sperm, i'd imagine that you'd end up with a baby boy.....now, you can always try gender selection and do IVF.....where the pull certain x's and y's out of him, or only 1 or the other....
i'm a google freak, and thought i'd look it up.....it has nothing to do with gender, bt it does say that having intercourse everyday can build up count and motility!!!
Sex every day is prescription for improving sperm quality
http://www.timesonline.co.uk/tol/life_and_style/health/article2665788.ece (a UK paper)
Men who suffer fertility problems because of low sperm quality may be able to improve their chances of fatherhood by having sex every day, research has suggested.
While those trying for a baby are often told to refrain from ejaculating too often to protect their sperm count, Australian scientists have shown that this can be counterproductive and may lower male fertility.
................the link is above to cut and paste, it's actually a really interesting story!!!
Yep... our RE told us to have sex everyday during our ovulation window to increase our chances of conceiving. It worked because now we are 10 weeks! Good luck... as far as I know, your husbands motility has nothing to do with gender. It is 50/50 that you will have a boy or girl :)
