Hello. I am 45 and OH is 54, we have decided to NTNP before I hit menopause and it's too late. (think I would always regret if i didn't and have been so broody recently) AF is regular and we are both quite healthy. Does anyone know if the age of the father affects how long the sperm can survive? We BD on Monday night and I ovulated later I think on Thursday night so 3 days after. I know that sperm can live upto 5 days but does this still apply for older mens?
