When a testicle "goes into your body," it typically refers to a retractile testicle, a common and generally harmless condition where the testicle temporarily moves out of the scrotum into the groin.
A retractile testicle is one that can move back and forth between the scrotum and the groin. This happens due to the cremasteric reflex, a muscle reflex that pulls the testicle up towards the body, often triggered by cold, excitement, physical activity, or even touch.
The good news is, it may seem alarming, but it's not a health risk. This condition is distinct from an undescended testicle (cryptorchidism), where the testicle never properly descends into the scrotum in the first place and is a more significant medical concern.
What Happens When it Retracts?
When a testicle retracts, it pulls up from its usual position in the scrotum. Key aspects include:
- Temporary Movement: The testicle does not stay in the groin permanently.
- No Pain: This movement is typically painless.
- Visibility: You might notice the scrotum appears empty on one side.
What to Do If a Testicle Retracts
The primary action regarding a retractile testicle is often minimal, as the body typically resolves it on its own.
- Self-Correction: The testicle often moves back down into the scrotum on its own, especially when the cremasteric reflex relaxes (e.g., in a warm bath, or when relaxed).
- Painless Manual Move: It may require a painless move by hand. This involves gently guiding the testicle down into the scrotum. If it stays in the scrotum for a while after being moved, it's considered retractile.
Who is Affected and Long-Term Outlook
Retractile testicles are most common in children. The excellent news for parents and individuals experiencing this condition is that most children grow out of a retractile testicle. As they grow older, the cremasteric reflex tends to weaken, and the testicles settle permanently in the scrotum.
Key Characteristics of a Retractile Testicle
To summarize, here are the defining characteristics:
| Feature | Description |
|---|---|
| Movement | The testicle moves freely and can be easily guided back into the scrotum. It often descends spontaneously. |
| Health Impact | It's not a health risk. Unlike an undescended testicle, a retractile testicle typically has normal function and does not pose the same long-term risks (e.g., fertility issues, increased cancer risk). |
| Age Group | Primarily observed in children, particularly between ages 2 and 7. The condition often resolves on its own by puberty. |
| Intervention | While often self-correcting, a gentle, painless manual push can help return it to the scrotum. Regular monitoring is usually sufficient. |
| Symptoms | Typically asymptomatic, meaning there's no pain or discomfort associated with the movement. The main "symptom" is the visible absence of the testicle from the scrotum. |
