Dumb Question - Semen Analysis

Alright, this question feels dumb, but I’m just not sure. If my husband and I wanted to get him a semen analysis done, would he have to get that set up with his primary doctor, or are there certain doctors he should be looking for to make an appointment with? Is there an equivalent to an OB for a man? 🤣 (kind of joking, kind of serious) I don’t want to waste time or money trying to make appointments with the wrong people. Thanks in advance!
