you will need to have him checked but not all testes on children (or men for that matter) are the same. some due "hang low and loose" so perhaps this is just a normal variation. i would not immediately feel that this would be an indication of something wrong. hi you say change of climate is this low hanging when its warm to hot if that's the case then your find all men and boys we do that its how they cool down and when its cold or been in swimming then they go up tight unless he's are still hanging down in cold conditions then yes there could be a problem and be looked at. so if its hot there down if its cold there up like this he's just normal. do hope this helps. good luck
testis of 6yr old is loose and hanging low. my nephew is 6year old. he is lean but very active. we have seen him prone to illness with sudden climate changes and often term it as low immunity. but this one is very concerning as it is sensitive. my nephew's testis (balls) are very loose and hangs low. his mother is worried if that is a negative indication. but we have not consulted a doctor for a physical checkup. please advice.
