You know what they say: 'Doctor Knows Best'! In this sixth installment of his popular medical Czech Up series, William Higgins introduces us to five more young men who are in for a surprise when they visit the doctor's surgery. No matter what the problem is, our doctors and male nurses know what these guys really need and the doctor is going to make sure they get it in the end -- and that's exactly where the patients get it in these Czech Ups!!
