What is retractile testicle?
A retractile testicle is a testicle that may move back and forth between the scrotum and the groin. When the retractile testicle is residing in the groin, it might be easily guided by hand into its proper position in the scrotum — the bag of skin hanging behind the penis — during a physical exam.
For most boys, the problem of a retractile testicle goes away sometime before or during puberty. The testicle moves to its correct location in the scrotum and stays there permanently.
In fewer than 5 percent of cases, the retractile testicle remains in the groin and is no longer movable. When this happens, the condition is called an ascending testicle or an acquired undescended testicle.
How common is retractile testicle?
Retractile testicles usually do not occur at birth or in infants younger than age 3 months. The cremasteric reflex is strongest between ages 2 and 7 years, and retractile testicles are most common in boys who are about 5 or 6 years old. Both testicles usually retract at the same time. Please discuss with your doctor for further information.
What are the symptoms of retractile testicle?
Testicles form in the abdomen during fetal development. During the final months of development, the testicles gradually descend into the scrotum. If this descent isn’t completed at birth, the testicle usually descends within a few months. If your son has a retractile testicle, the testicle originally descended as it should, but doesn’t remain in place.
Signs and symptoms of a retractile testicle include:
- The testicle may be moved by hand from the groin into the scrotum and won’t immediately retreat to the groin.
- The testicle might spontaneously appear in the scrotum and remain there for a time.
- The testicle might spontaneously disappear again for a time.
The movement of a retractile testicle almost always occurs without pain or discomfort. As a result, it’s noticed only when the testicle is no longer seen or felt in the scrotum.
The position of one testicle is usually independent of the position of the other one. For example, a boy might have one normal testicle and one retractile testicle.
Retractile testicle is different from undescended testicle (cryptorchidism). An undescended testicle is one that never entered the scrotum.
There may be some symptoms not listed above. If you have any concerns about a symptom, please consult your doctor.
When should I see my doctor?
During regular well-baby checkups and annual childhood checkups, your son’s doctor will examine your son’s testicles to determine if they’re descended and appropriately developed. If you believe that your son has a retractile or ascending testicle — or have other concerns about the development of his testicles — see his doctor. He or she will tell you how often to schedule checkups to monitor changes in the condition.
If your son experiences pain in the groin or testicles, see your son’s doctor immediately.
What causes retractile testicle?
An overactive muscle causes a testicle to become a retractile testicle. The cremaster muscle is a thin pouch-like muscle in which a testicle rests. When the cremaster muscle contracts, it pulls the testicle up toward the body.
The main purpose of the cremaster muscle is to control the temperature of the testicle. In order for a testicle to develop and function properly, it needs to be slightly cooler than normal body temperature. When the environment is warm, the cremaster muscle is relaxed; when the environment is cold, the muscle contracts and draws the testicle toward the warmth of the body. The cremaster reflex can also be stimulated by rubbing the genitofemoral nerve on the inner thigh and by extreme emotion, such as anxiety.
If the cremaster reflex is strong enough, it can result in a retractile testicle, pulling the testicle out of the scrotum and up into the groin.
Causes of an ascending testicle
Some retractile testicles can become ascending testicles. This means the once-movable testicle becomes stuck in the “up position.” Contributing factors can include:
- Short spermatic cord. Each testicle is attached to the end of the spermatic cord, which extends down from the groin and into the scrotum. The cord houses blood vessels, nerves and the tube that carries semen from the testicle to the penis. If growth of the spermatic cord doesn’t keep pace with other body growth, the relatively short cord might pull the testicle up.
- Remnants of fetal tissues. Abnormal remnants of fetal tissues that created the path for normal testicular descent might affect the growth or elasticity of the spermatic cord.
- Scar tissue from hernia surgery. An inguinal hernia is caused by a small gap in the abdominal lining through which a portion of the intestines can protrude into the groin. Scar tissue following surgery to repair the hernia might limit the growth or elasticity of the spermatic cord.

Diagnosis & treatment
The information provided is not a substitute for any medical advice. ALWAYS consult with your doctor for more information.
How is retractile testicle diagnosed?
Retractile testicle is diagnosed with a physical exam. During the exam it is important for your son to be as relaxed as possible. Certain positions can decrease the cremasteric reflex, such as sitting crossed-legged and squatting in a catcher position.
As long as the testicle can be easily guided into the scrotum and remain there independently, without tension, the testicles are considered retractile.
How is retractile testicle treated?
A retractile testicle is likely to descend on its own before or during puberty. If your son has a retractile testicle, your son’s doctor will monitor any changes in the testicle’s position in annual evaluations to determine if it stays in the scrotum, remains retractile or becomes an ascending testicle.
If the testicle has ascended — no longer movable by hand —your son’s doctor will likely recommend surgery to move the testicle permanently into the scrotum. Also, if the testicle is still retractile during puberty, surgery will likely be recommended in the early teen years to ensure proper maturation of the testicle.
During this surgical procedure (orchiopexy), the surgeon frees the testicle and cord from any attached tissues, positions the testicle in the scrotum and stitches it into place.
After surgery, bicycle riding must be avoided and other sports activity limited for a couple of weeks. Follow-up exams to assess wound healing and the position of the testicle will be needed two weeks after surgery and again after six months.
Adolescent boys and men who have had treatments to correct an ascending or retractile testicle should regularly monitor the position of the testicle to ensure it doesn’t ascend at a later time.
Although hormone treatments have been used to treat ascending testicles or retractile testicles in adolescents, the American Urology Association’s 2014 guidelines no longer include this intervention because of a lack of evidence for successful response or long-term effectiveness.
Lifestyle changes & home remedies
What are some lifestyle changes or home remedies that can help me manage retractile testicle?
The following lifestyles and home remedies might help you cope with retractile testicle:
- Check the position of the testicles regularly during diaper changing or at bath time. Keep a record of any changes.
- Give your son the vocabulary to talk about the scrotum and testicles. Explain that there are usually two testicles in the scrotum.
- When he’s about to reach puberty — usually around sixth grade — and you’re talking about what physical changes to expect, explain how he can check his testicles.
- Explain in simple terms what a retractile testicle is.
- Remind him that there’s nothing wrong with him.
- Explain that the position of the testicle is something you, your son and his doctor will pay attention to and fix, if necessary.
- Help him practice a response if he’s teased or asked about the condition.
- Buy loosefitting boxer shorts and swim trunks that might make the condition less noticeable when changing clothes and playing sports at school.
- Be aware of signs of anxiety, such as not participating in sports that he would normally enjoy.
If you have any questions, please consult with your doctor to better understand the best solution for you.
