Can Dietary Supplements Cause Sudden Low Testosterone And Erectile Dysfunction 20 Days After Unprotected Sex?

Hello, I am 44 years and I have not had problems with Erectile dysfunction before until I had unprotected sex 20 days ago, I went to my doctor and the test showed my testosterone is very low, I no longer have the urge for sex, I cannot sustain an erection, in the morning my penis is completely down, I am suspecting my general use of dietary supplements can be the cause, please assist. Thank you in advance. Steve
