Had my infected testicle removed at 14. im curious as to what exactly happened in the surgery, as it was removed from lower abdomen. Is there a video?

Unlikely to have. Video taped best way is request the copy of hospital chart. Most likely surgery you had is due to testicle torsion. One is enough for all purposes including for fertility, you can have silicone testicle inserted to to the scrotum to match other if you are uncomfortable.
