Dear Ketan:
From what I understand the whole "low T" thing is a scam. Lots of men are being treated just because they have a slightly low testosterone level. Big Pharma has been pushing this--we've all seen the ads.
Low testosterone levels are a normal function of aging, obesity, and other factors. A lab test alone does not clinch a diagnosis of androgen deficiency. The Endocrine Society issued some excellent guidelines on this issue in 2010:
