If your husband does not have sperms in the semen ,you can't be pregnant.There are two reasons -either sperms are not being made in testes or if made the sperms are not coming out in semen.
If sperms are not being made , sperm bank is of immense help.Just like you withdraw money from bank you can take sperms from sperm bank.Sperms so recieved , are put inside your uterus directly so that the chances of pregnancy increases.
