I have, in my entire life, made up only one joke worthy of standup comedy. It is perhaps similar to Stephen Wright’s “I live on a one-way, dead end street”.
It goes “Is infertility hereditary?”

Sons born with fertility treatment ‘inherit problems’
Boys born to fathers who needed help conceiving grow up to have poorer sperm quality than peers conceived without help, a study has found.
