Can sperm quality cause miscarriage

Amiee 🇬🇧👧🏼👼🏻

Hey

Someone told me once that low sperm count/quality etc can result is miscarriage? Like making the fertilisation not strong enough for the foetus to grow?

surely that can’t be true because of the sperm is strong enough to fertilise an egg it’s then down to egg/womb etc

I’m confused :/ hahaah
