What Condition Results From Failure of the Testis to Descend Into the Scrotum?
An undescended testicle (or "testis") is when it fails to drop into the normal place in the scrotum. Your child's wellness care provider tin find this during a routine exam. This issue is found in nigh 3 or iv out of 100 newborns (and up to 21 out of 100 premature newborns). Luckily, about half of these testicles will drop on their own during the starting time 3 months of life. But testicles won't driblet on their own later 3 months of historic period. Thus, about i or two out of 100 boys with undescended testicles volition need treatment.
It'due south important non to misfile undescended testicles with "retractile" testicles. After 6 months of age, a male person kid has a reflex that temporarily pulls the testicles up to protect them when he's common cold or frightened. These testicles are in the scrotum at other times and don't demand treatment. Only testicles that are truly undescended need treatment. A pediatric urologist can tell the difference with a physical exam.
The testicles demand to be 2 to 3 degrees libation than normal torso temperature to make sperm. The scrotum is many degrees cooler than trunk temperature, and and then is the ideal place for the testicle. Testicles that don't drib into the scrotum won't piece of work normally. The longer the testicles are also warm, the lower chances are that the sperm in that testicle will mature ordinarily. This tin can be a cause of infertility, especially when both testicles are affected.
Undescended testicles are as well linked to a higher risk of:
- Testicular cancer in adulthood (though the gamble is still less than 1 in 100)
- Testicular torsion (twisting of the chord that brings claret to the scrotum)
- Developing a hernia near the groin

What Happens nether Normal Conditions?
The testicles (or "testes") are two organs that hang in a pouch-similar skin sac (the scrotum) below the penis. The testicles are where sperm and testosterone (the male sex hormone) are made. The scrotum keeps the testicles in a cooler setting than the body. This is because sperm can't grow at torso temperature. During childhood, sperm in the testicles go through a process that results in mature sperm at puberty.
Normal testicles form early in a baby boy'south growth. They grade in the lower belly (abdomen), but descend, or "drop," into the scrotum toward the end of pregnancy. Normal testicles attach themselves with stretchable tissue in the bottom of the scrotum. This is controlled past the baby's normal hormones.
In about children with this wellness issue, it'south non known why the testicles neglect to drop. It may be because the testicles aren't normal to start with. In other cases, there'south a mechanical trouble. The testicles drop but miss the scrotum, ending upwardly next to the scrotum instead. These are called "ectopic testicles." Or it may be that the infant'south hormones tin can't stimulate the testicles normally. No studies have shown that the trouble is caused by something the mother did or ate during pregnancy.
Sometimes the testicles drib but don't attach in the scrotum. So, when the boy grows, it becomes clear that the testicles aren't fastened. About 1 of every 5 cases of undescended testicles are establish once the boy is no longer a baby. For this reason, all boys should have the location of their testicles checked during each almanac concrete exam.
A testicle that can't be felt in a physical examination is called "nonpalpable." Nonpalpable testicles may be in the abdomen (undescended), absent, or very small ("atrophic"). It'due south of import to detect out whether there is a testicle that hasn't dropped. An undescended testicle left inside the abdomen could form a tumor later in life. Such a tumor might non be noticed until it becomes quite big or causes symptoms. Unfortunately, there's no exam, such as an ultrasound, that tin can definitively bear witness whether a testicle is there. Surgery is the only way to find out for sure.
Pediatric urologists are experts in both open up and laparoscopic surgery. Laparoscopy is surgery done through thin tubes put into your kid'southward body through a modest cutting. The surgeon uses a special camera to see inside your child's body. The surgeon volition find one of iii situations:
- Blind-ending testicular blood vessels – proving there's no testicle
- Vessels leaving the abdomen – proving in that location'southward no testicle in the abdomen
- A testicle in the belly. If a testicle is establish, it's brought down into the scrotum or removed, based on its condition.
The testicle won't drop after iii months of age, so the only handling choice is surgery. Surgery is recommended after 6 months of age. The timing takes into account when the child is able to handle anesthesia and the surgery. Drugs or hormone treatment aren't useful.
This surgery is chosen an orchiopexy. The child is put under (general anesthesia) for this surgery. Nigh always the child can become home the same solar day and is back to normal within i to two days. A cut about 1 inch long is made in the groin area (near often it can hardly exist seen later). The testicles is freed from all nearby tissues so that it moves easily into the scrotum. Then information technology is stitched into identify. If there's a hernia, it's stock-still at the same time. In some cases, the testicle is too loftier for this simple surgery. If this is the instance, more than complex methods (and sometimes even 2 surgeries) are needed. Overall, the success rate with surgery is 98 out of 100.
After treatment, the testicle frequently grows to normal size in the scrotum. In some cases, the testicle wasn't normal to kickoff with, and never grows the correct way. In other cases, sperm never grow, even though the testicle size is normal. In most cases, later treatment for 1 undescended testicle, fertility becomes normal and the chances of fathering a kid in the future are high. When the child becomes a teen, he should have routine physical exams and do monthly testicular self-exams. Routine physicals will look for signs of testicular cancer, which remains a slight risk.
Is an undescended testicle always found in babies?
No. Nearly i of every 5 cases of undescended testicles are found afterward the male child is no longer a baby. The testicles of these boys appeared to take dropped normally every bit babies. If an undescended testicle appears subsequently information technology is called an "ascending testicle." This happens because the testicle doesn't "fix" itself in the scrotum, and is noticed as the kid grows. Frequently these boys are known to have a retractile testicle before they are diagnosed with an ascending testicle. These testicles demand surgery to movement them into the scrotum. Sperm won't mature if the testicle stays undescended. For these reasons, boys should have their genitals checked during their yearly physical exam.
