Understanding testicle descent concerns

Parents often search for answers when a boy’s testicle does not seem to be in the scrotum, when only one testicle appears descended, or when descent seems delayed. In many boys, testicles descend before birth, but some children have an undescended testicle or a testicle that moves in and out of the scrotum. During puberty, body changes can make parents and teens notice these differences more clearly. This page is designed to help you understand common patterns, what to look for, and what questions to ask next.

Common situations parents notice

One testicle not descended

If one testicle does not seem to be in the scrotum, parents may notice one side looks fuller than the other. This can happen with an undescended testicle or a retractile testicle that moves upward.

Both testicles not in the scrotum

If both testicles do not seem to be in the scrotum, it is understandable to want prompt guidance. A clinician can help determine whether the testicles are undescended, difficult to feel, or temporarily pulled upward.

Late descent in puberty

Some families become concerned when a testicle seems to have descended late in puberty or when normal development is unclear. Puberty can make these concerns more noticeable, especially if body changes are happening at different times.

How to tell if testicles have descended

Look for position in the scrotum

A descended testicle is usually felt in the scrotum. If the scrotum seems empty on one side or both sides, that is a common reason parents seek guidance.

Notice whether it moves

Some boys have a testicle that seems to move up and down. This may happen with a retractile testicle, which can sometimes be brought into the scrotum and may not stay there consistently.

Consider age and development

Questions about testicle descent age in boys are common. If you are unsure whether what you are seeing fits your child’s age or stage of puberty, personalized guidance can help you decide what to do next.

When parents usually want more guidance

A child’s testicle is not in the scrotum

If a child’s testicle does not seem to be in the scrotum, parents often want help understanding whether this could be an undescended testicle or a normal variation that still needs monitoring.

There is a new concern during puberty

Testicle descent concerns in puberty can come up when a teen notices body changes, asymmetry, or a testicle that seems to have descended later than expected.

You are not sure what is normal

Many parents simply want a clearer sense of what to watch for, what terms like undescended or retractile mean, and when it makes sense to speak with a pediatrician or specialist.

Frequently Asked Questions

When do testicles descend in boys?

In many boys, the testicles descend before birth. If a parent notices that a testicle is not in the scrotum during infancy, childhood, or later, it is reasonable to ask a clinician for guidance on whether this may be an undescended or retractile testicle.

What does it mean if one testicle is not descended?

If one testicle is not descended, the scrotum may look or feel different on one side. Sometimes the testicle is undescended, and sometimes it moves up and down. A medical exam is usually the best way to tell the difference.

Can a testicle descend late in puberty?

Parents and teens sometimes worry that a testicle descended late in puberty. Because puberty timing varies, it can be hard to know what is normal from appearance alone. If descent seems delayed or unclear, a clinician can help assess what is happening.

How can I tell if my child has an undescended testicle?

A common sign is that one or both testicles do not seem to be in the scrotum. Some testicles are easy to feel, while others seem to move upward. If you are unsure how to tell if the testicles have descended, it is a good idea to get individualized guidance.

What if a testicle seems to move up and down?

A testicle that moves up and down may be retractile, meaning it can shift between the groin area and the scrotum. This is different from a testicle that stays outside the scrotum. Because the difference can be hard to judge at home, a clinician can help clarify it.
