Final answer:
The best response for a newborn with an enlarged and swollen scrotum on one side is that it could be a collection of fluid known as a hydrocele, which often resolves on its own without intervention. However, a proper evaluation by a pediatrician or pediatric urologist is essential to rule out other conditions and ensure correct treatment.
Step-by-step explanation:
The concern regarding a newborn's enlarged scrotum on one side could potentially be due to a common condition in newborns. Based on medical knowledge, if there is no evidence of pain, discoloration, or associated symptoms, this could likely represent a hydrocele. A hydrocele is a collection of fluid within the scrotum that typically resolves spontaneously within the first year of life. It is imperative for the newborn to be evaluated by a pediatrician or a pediatric urologist to ensure correct diagnosis and appropriate management. If it is indeed a hydrocele, usually no immediate intervention is necessary as the condition often corrects itself. However, if the swelling is due to a hematoma or another cause such as epididymitis or testicular torsion, medical intervention may be required. It is not common for one gonad to be significantly larger than the other in the absence of any underlying condition, and the swelling is also not typically due to birth trauma.
