In a society that is still heavily patriarchal, women face constant pressure to have a family. If they plan to have children, society badgers them to get pregnant by the age of 35. Otherwise, they face the risk of miscarriage and/or infertility.

Turns out that is a misconception. The focus on a woman’s biological clocks lets the blame fall on her if she experiences any difficulties while trying to conceive. It has allowed men’s biological clocks to go unnoticed. Yes, men have them too. Contrary to popular belief, men don’t have power sperm that are good to go at any age. According to research at UC-Berkeley, their sperm becomes abnormal or unhealthy at age 22.

Guys, especially the douchebags, have nothing to worry about when it comes to their sperm though. According to research at UC-Santa Barbara, the narcissistic, complacent and rambunctious types have more prolific sex lives. Who knew? It makes sense when you think about it since they are more likely than nice guys to cheat and have one-night stands. Let's just hope they don't get anyone pregnant.

Speaking of nice guys, as long as they have children by the age of 40, they have nothing to worry about either.
