Love how this is the first post and nobody has challenged this statement's veracity. Just as women start having increased chances of miscarriage and birth defects when getting pregnant at 35 or older, men's sperm quality starts to degrade around the age of 40, which can cause a host of similar health issues both for the mother and the baby due to genetic mutation. While men may be fertile for life, there definitely is an optimal range for reproductive health, and it is only 5 years more than women get. If you're over 40, please get your guys checked out before you knock someone up.
Just one article, using a search engine will turn up a ton more.

To stay slightly on topic, partner and I are pretty similar in height, but glad I didn't have to use online services to find them. My only experiences with that are secondhand and they've been a huge bust. Reading the messages sent by males to females and reading bot messages is depressing, and I've been out of the game for nearly 20 years.
