It turns out that sperm morphology is a big deal when it comes to fertility. If a guy's sperm are all weirdly shaped, it can make it harder for them to swim to the egg and fertilize it. It's like trying to win a swimming competition with a broken tail!
But here's the cool thing - sperm morphology can be affected by all sorts of things, like lifestyle choices and environmental factors. For example, smoking and excessive heat can both make sperm go a little haywire. Who knew that smoking could make your sperm go crazy?
