so, from what i understand, girl sperm last longer but are slower. boy sperm are quicker but die off faster.

i concieved after late ovulation and a week after i ovulated. would that mean its more likely im,having a girl?? i know its not a sure thing or anything, just wondering! has anyone,found this,to be true??
