My DS is 15 months and since birth was thought to have a hydrocele but a scan today showed things were more complex as they initially struggled to find his right testicle and then when they did find it they realised it was much smaller and under developed.
The radiologists were a bit cagey about it all and naturally Google has worried me senseless 
Does anyone know much about atrophic testicles or have experience of it. I feel worried and upset
