Unlikely: Testicles are glands that produce testosterone. When glands appear in pairs in the body and one gland gives up, the other gland will compensate for that - unless that gland is sick, too. A blood test will reveal if the remaining gland is functional.
Dr. John Berryman

Gynecomastia: Loss of one testicle is compensated by forcing the remaining testicle to produce more. Increase in breast tissue in males is usually a genetic condition (runs in families). Low testosterone alone will not produce gynecomastia, but should be investigated by an endocrinologist. Being overweight can in some individuals cause this condition.
