OK, so there hasn't been a boy born on my husband's direct family line for 5 generations or something. Hubby is one of 3 boys and his brothers have 2 boys each. We are expecting our first and surprise, surprise - it's a boy!
I had no preference so am happy but I am curious.
Is it possible that some men simply have fewer or no sperm with an 'X' chromosome?
Not sure how this would actually be tested and I have no idea of genetics, but just wondering........
