You are answering from a medical point of view...... Is this correct?
Long time user and a long time since i have frequented a board. My 2 cents is eveyone is disposed to diferent sides. Not having kids is rarely an issue, yes over time you will lower your sperm count drastically but this will return to normal with time after you stop using. Other health issues should be of more concern. I saw an eamil recommending getting your blood checked, good idea especially when using orals, and really a good habit to have done once a year.
Tests:
Liver panel
LDL/HDL panel (Cholesterol Panel)
make sure the do a complete blood panel (red blood cell count, thickness)
Good Luck
