I'm a 19 year old Indian male. I recently had a testosterone test done after reading RoK and other material and the report says my serum test. level is 235. My vitamin D level is 17.4. Also, I have a hair fall problem and pretty low facial hair for my age. Should I be worried?

Edit: I visited my family doctor. He asked me questions about my sexual health, checked my testicles and then checked my chest for lumps, etc. He concluded that it was just a normal fluctuation amplified by my vitamin D insufficiency (I even had slightly low hemoglobin). He prescribed me a Vitamin D supplement and a protein powder with all kinds of vitamin B. He told me to wait for one year and do another test and then visit him.
