Married for the last 10 years with no child

I am 37 years old male, weigh 80 kg and I am married for the last 10 years with no child. My wife is 30 years old and weighs 65 kg. I suffer from low sperm count/sperm morphology, weak erection/premature ejaculations/erectile dysfunction, thin, small and week penis. No drugs or alcohol.

We are trying to have a baby for the last 10 years. My wife has never been pregnant. We have been to many doctors, gynecologists etc. We have done many tests. I have done Semen Analysis test, Sperm DNA Fragmentation test and Scrotal Ultrasound.

My wife also went through Pap test, Sonohysterogram test, Sonosalpingogram test. Her fallopian tubes are open as well. She has used medicines like Clomid, Letrozole etc.
