Scrotal Swelling and Short Penis Concerns in Infants - Urology

Penile issues


Hello Dr.
Tsai: My son has just turned one year old.
When he was born, he had scrotal swelling, which made his scrotum appear quite large—large enough that we suspected a hernia at one point.
However, it has decreased significantly, although there is still some scrotal swelling present.
I would like to ask you: how large can scrotal swelling be observed before deciding whether surgery is necessary? Additionally, my son's penis appears to be very short; at times, it seems like we can only see a tiny bit of the surface.
The doctor mentioned that he has more fatty tissue above his genitalia, which is between the genitalia and the navel, causing the penis to be retracted.
Moreover, when I try to extend his penis, it tends to point upwards, which makes me quite worried about whether this will affect his future happiness.
You might find my concerns a bit silly or amusing, but I would appreciate your guidance.
I have heard of a condition called "hidden penis," which generally refers to a lack of elasticity in the muscle tissue within the penis structure, and it seems that surgery might be required for that.
Is it possible that my son has this issue?

Hello, you are truly a caring and attentive mother.
Scrotal swelling, or hydrocele, typically occurs around the age of one and may resolve on its own; however, the chances of spontaneous resolution decrease after the age of one.
Hydrocele itself does not affect fertility, but it can cause cosmetic concerns.
If surgery is delayed until the child is older, it may impact the child's psychological development.
Conversely, performing surgery at a very young age carries higher anesthetic risks.
Therefore, determining the appropriate timing for intervention is a multifaceted consideration.
Generally, it is recommended to wait until after 18 months for surgery, but it is not advisable to delay beyond the start of school.
This is because, after starting school, children may compare themselves to peers, which can affect their self-esteem.
Of course, if the symptoms are very mild or show signs of improvement, it is best to wait and not rush into surgery.
Additionally, scrotal swelling in infants is often associated with hernias, which are typically addressed during the same surgical procedure.
Regarding penile development in infants around the age of one, it can be challenging to assess, especially since many children today are chubby, which can lead to what is humorously referred to as "McDonald's syndrome." In these overweight children, excess fat at the base of the penis can cause it to appear buried, clinically referred to as buried penis.
In simple terms, the penis itself is normal; it is the surrounding adipose tissue that is abnormal.
As for your concerns about abnormal penile development, I personally have not encountered many cases in clinical practice.
However, does your child experience morning erections? If there are instances of erections, the issue is likely not serious.
If you are still concerned, it would be advisable to consult a urologist or pediatrician for a thorough evaluation, which should provide you with peace of mind.

Sincerely,
Director of Urology, Dr.

Scrotal swelling and concerns regarding the size of the penis in infants can understandably be a source of anxiety for parents. It’s important to approach these issues with a clear understanding of the normal developmental variations in infants and the potential medical concerns that may arise.

Scrotal Swelling (Hydrocele)
In infants, scrotal swelling is often due to a condition known as a hydrocele, which is the accumulation of fluid in the scrotal sac surrounding the testicles. Hydroceles are quite common in newborns and usually resolve on their own within the first year of life. In many cases, if the hydrocele is not causing any discomfort and is not associated with other symptoms, it can be observed without immediate intervention.
Typically, a hydrocele can be monitored until the child is around 1 to 2 years old. If the swelling persists beyond this age or if it increases in size, becomes painful, or is associated with other symptoms such as redness or fever, surgical intervention may be considered. The surgery, if needed, is usually straightforward and involves removing the excess fluid and closing the sac.

Concerns About Penis Size
Regarding your concerns about your son’s penis size, it’s important to note that there is a wide range of normal when it comes to genital size in infants and young children. The appearance of a short penis can sometimes be attributed to the presence of excess fatty tissue in the pubic area, which can make the penis appear smaller than it actually is. This condition is often referred to as "hidden penis" or "buried penis."
In most cases, this is a normal anatomical variation and does not require treatment. However, if the penis is truly buried and cannot be easily exposed, or if there are concerns about urinary function or hygiene, it may warrant further evaluation by a pediatric urologist.
Peyronie's Disease and Other Concerns
You mentioned concerns about a condition related to the elasticity of the penile tissue. In older children and adults, conditions like Peyronie's disease can affect penile curvature and size, but this is not typically a concern in infants. The anatomical structures of an infant's penis are still developing, and many of these concerns may resolve as the child grows.

Conclusion
It’s completely understandable to worry about your child’s health and development. However, it’s essential to remember that many of these conditions are common and often resolve on their own without intervention. Regular check-ups with your pediatrician can help monitor your child’s development and address any concerns you may have. If you feel uncertain or anxious about your child’s condition, don’t hesitate to seek a second opinion or consult a pediatric specialist. They can provide reassurance and guidance tailored to your child's specific situation.
In summary, while scrotal swelling and concerns about penis size can be concerning, they are often benign and part of normal development. Monitoring and regular pediatric evaluations will help ensure that any potential issues are addressed appropriately.
