The paper from Floresta et al.1 presents data from two cohorts of men (mean age 35) attending for infertility assessment.A distinction is made between the classical hypogonadism (total testosterone [TT]12 nmol 1-1 or less) and “subclinical” hypogonadism with a normal TT but marginally raised luteinizing hormone (LH).They also stress that too much emphasis should not be placed on the need for the presence of sexual symptoms and stress the importance of obesity,insulin resistance,and type 2 diabetes.They rightly point out the relationship between low testosterone (T),low-vitamin D,and increased mortality along with increased risk of type 2 diabetes.2-4 These are vitally important issues that should concern us all and yet we must ask ourselves why these accepted views in the fields of andrology and sexual medicine are not widely held by our colleagues in diabetes and endocrinology.
