Semen analysis

Will your RE take a semen analysis from places like quest diagnostic or lab corp? (I live in NY but am going to an RE in CT) i know at places like this u can have ur SO bring the sample in from home & i think thats really the only way he will do it unfortunatly as hes really embaressed about it . But will they accept it from labs or does it have to be done in office of that dr? Also can u make ur own appointment for it at quest or lab corp without a referral from his dr & pay out of pocket? Or does he have to have one? Any ans will help ! Thank u !!
