well it could be. or it might not be. low testosterone (or "low t") is the flavor-of-the-month in men's health. it's blamed for everything from lack of energy to low libido. and while low testosterone certainly might contribute to those things it's probably not the sole underlying cause. many things can cause slow weight loss and erectile dysfunction (ed). your best bet is to see your primary care provider for a range of blood tests. these basic tests can help pinpoint the cause(s) of your current health conditions and get you on the path to wellness. by the way good job on the diet and exercise! even though things are slow going keep up the good work. wishing you well!
if a man is dieting exercising at least 3 to 4 times a week having ed having a hard time losing weight. low t?
