If my female cousin goes to a sperm bank to get pregrant and years ago i had given sperm to that sperm bank.......and she just happens to pick my sperm.......or could that NOT happen??? i know the odds are way out there....but anything can happen. even if it was not me and my cousin and just any guy that gave to a sperm bank and then some relative goes to one and picks his sperm is that wrong or just happens???
