Ok I may sound stupid but I have no idea

Karina • Trying to conceive baby number one 🍼🤞🏼💖 over 3 years trying with unexplained fertility 🥺😞

Basically when a guy has to go get his sperm checked out does he have to do it in the clinic or can we do this at home and take it there? My man is getting all funny about it 🤦🏻‍♀️ sorry if this is a stupid question!
