I m 42, in good shape, muscular, and take low dose testosterone. in the last 6 months, I ve noticed a decrease in sex drive, some ED which has resulted in me taking viagra, and a very noticeable decrease in my ejaculate. I haven t changed anything when it comes to the number of times I ejaculate a week, and am concerned. I don t have any other symptoms....Should I see a urologist? I eat pretty healthy and consume veggies, zinc, and plenty of nuts and vitamins.
