What does this have to do with the Celiac Sprue?
I believe they were explaining the reason for the mentioned "mild osteopenia" in the pt presentation.
No, I think this person got confused with another question about celiac sprue, PTH, Calcitriol, and Vit D (it was an arrow type question).
explanation for decreased bone density .
My best guesss: Sperm/semen need to be at a lower temperature than body temp (why testicles hang away from body). Varicoceles contain warm blood that would more likely cause infertility.
