Hcg injections having pain in that regio

Hello Doctors, I am Raj, Around 2015 i was down with a fever and i was having an infection on my right testis. I wasn't aware of it. After a few years i started having pain in that region. I ignored it In 2018 i went for an ultrasound of testis and i got to know I'm having testicular atrophy. And i consulted various doctors in homeo, allopathy, Ayurvedic etc. Had very slight changes but I'm back to square one. -No hair on face and body - Atrophy - started smoking due to stress. So i again consulted again this year, the doctor suggested I go for HCG injections but as per my knowledge on this ( Google research) -How effective is the HCG? -Why does it stop working after stopping HCG injections? -Is there any permanent cure for this? -HCG are for life time?
