Hello, thanks for your query Failure to ejaculate- anejaculation maybe associated with or without orgasm. Sometimes it may also be associated with dry ejaculation or retrograde ejaculation(ejaculating semen into the bladder). You can consult your local urologist who will need to examine your husband,see his medication and then decide on medication required by him. If pregnancy and ejaculation are related issues, then some form of assisted reproduction maybe possible I hope i have answered your query. I will be happy to answer any further queries that you may have thanks Dr.vineet malhotra
