Lathargy , low T, now lost libido.

I am medical professional myself. I was fine untill 1.5 yrs back. And I started noticing low energy levels, lathargy forgetfullness sad moodand sudden drop in libido. Started exercising regularly.and got checked. My vit b12 d3 and s. Test were quite low. Initial s.T 273 ish. Taking supplements regularly. Now better b12 n d3. Took ayurvedic supplement n high protein and heavy gym. T raised to 500s.. but still my libido and drive was all kinda gone. Been struggling since past 1.5 yrs. Current test 470s .. the Gym feels as if I need to rest 2 days with every heavy day despite protein. Libido still low. All my amazing and crazy drive is all gone. Married now. Weak erection less drive and some PE. (Used to masturbate 12-15 times a month atleast to now 2-3 times. This too in a matter of 1 year. ) As if this wasn't enough.. I felt my testicles have shrunk. And got a USG done. It's 10.4-11 cc each and data says it should be 15-18 cc for someone in youth. Help!! Should start clomid?
