How does the age of the sperm father affect a pregnancy?

Sperm quality tends to decrease with age. In particular, the shape (morphology) and movement (motility) of your sperm are both likely to deteriorate as you get older, making it more difficult for them to fertilise an egg(Harris et al 2011, Harris 2019). You may also produce less sperm as you age. (Harris 2019)
