Infertility and dog fur?

Hi everyone! I read online that infertility can be caused by animal hairs such as dogs. My cousin also had a hard time getting pregnant and when seen by her doctor, they told her it could’ve been caused by dog fur. Does anyone have any knowledge on this? I’m trying to get the facts straight and since I’m TTC, I want to be sure because I have two dogs that shed and want to know if I should be cleaning more often than normal.

Thanks!! 🙂
