Undescended testicles can lead to fertility issues and increased cancer risk if untreated, but timely medical care offers effective solutions.
The Biological Journey of Testicular Descent
Testicular descent is a crucial process in male development, typically occurring before birth or shortly after. During fetal growth, the testicles form inside the abdomen near the kidneys. As the fetus matures, these glands gradually move down through the inguinal canal into the scrotum—a pouch of skin outside the body designed to maintain optimal temperature for sperm production.
This descent happens in two main phases. The first phase, called the transabdominal phase, involves movement from the abdomen toward the internal inguinal ring. The second phase, known as the inguinoscrotal phase, guides the testicles through the inguinal canal into their final position in the scrotum. Hormones like testosterone and a peptide called insulin-like 3 (INSL3) play vital roles in regulating this complex journey.
If this natural migration is disrupted or incomplete, one or both testicles remain undescended—a condition medically termed cryptorchidism.
Understanding Cryptorchidism: When Testicles Don’t Drop
Cryptorchidism affects about 3% of full-term male infants and up to 30% of premature boys. The condition can be unilateral (one testicle undescended) or bilateral (both undescended). Sometimes, an undescended testicle may be located anywhere along its typical path—from inside the abdomen down to just above the scrotum—or it may be ectopic, meaning it’s found outside this path.
The exact reasons why some testicles fail to descend aren’t fully understood. Genetic factors, hormonal imbalances, maternal health conditions during pregnancy (like diabetes or smoking), and environmental influences have all been implicated. Certain syndromes and anatomical abnormalities can also interfere with normal descent.
Signs and Detection
In newborns and infants, doctors routinely check for descended testicles during physical exams. If one or both are not palpable in the scrotum by six months of age, further evaluation is warranted. Ultrasound imaging or laparoscopy may be used to locate non-palpable testicles.
Left untreated beyond infancy, undescended testicles rarely descend spontaneously after six months old. This delay raises concerns about long-term health risks.
Health Risks Linked to Undescended Testicles
The consequences of leaving an undescended testicle untreated extend beyond cosmetic concerns. Several significant health risks arise:
- Infertility: The scrotum provides a cooler environment essential for sperm development. An undescended testicle exposed to higher body temperatures often produces fewer viable sperm cells.
- Testicular Cancer: Males with cryptorchidism have a 3-8 times higher risk of developing testicular cancer compared to those with normally descended testes.
- Testicular Torsion: An undescended testicle is more prone to twisting around its blood supply, causing severe pain and possible loss of function if not treated promptly.
- Hernias: Since descent involves passage through the inguinal canal, incomplete closure can result in inguinal hernias.
- Psycho-social Impact: In older children and adults, undescended testes may cause self-esteem issues related to appearance or sexual function.
The Infertility Factor Explained
Spermatogenesis—the production of sperm—requires temperatures approximately 2-4°C below core body temperature. When testes remain inside the abdomen or high in the groin where temperatures are warmer than ideal, sperm cells develop abnormally or fail altogether.
Studies show that men with untreated bilateral cryptorchidism often face severe infertility issues later in life due to impaired sperm count and motility. Unilateral cases carry lesser but still significant risks.
Treatment Pathways: Correcting Undescended Testicles
Medical intervention is key once it’s clear that spontaneous descent won’t occur by six months of age. Early treatment improves fertility outcomes and reduces cancer risk.
Surgical Approach: Orchiopexy
Orchiopexy is a surgical procedure performed under general anesthesia that relocates an undescended testicle into the scrotum and secures it there permanently.
Typically done between 6 months and 18 months old, this surgery involves making a small incision in the groin area or lower abdomen to locate and mobilize the testicle before placing it into a created pouch within the scrotal sac.
Success rates are high—over 95%—with minimal complications when performed by experienced pediatric urologists or surgeons.
Hormonal Therapy
In some cases, hormonal treatments like human chorionic gonadotropin (hCG) injections aim to stimulate natural descent by increasing testosterone levels temporarily. However, this method has variable success rates and is less commonly used now compared to surgery.
Hormonal therapy might be considered as an adjunct treatment or when surgery isn’t immediately feasible.
The Importance of Early Diagnosis and Follow-Up
Delaying treatment beyond infancy can have lasting consequences on reproductive health and increases cancer risk substantially.
Regular follow-ups after orchiopexy are essential because:
- The repositioned testicle needs monitoring for proper growth and function.
- There remains a small but real chance of developing malignancy even after surgery.
- Some boys may require additional interventions if initial surgery fails or complications arise.
Pediatricians recommend routine self-examinations starting at puberty for early detection of abnormalities.
A Closer Look: Data on Cryptorchidism Outcomes
| Condition Status | Fertility Impact | Cancer Risk Increase |
|---|---|---|
| Treated before 1 year old | Minimal impact; near-normal fertility expected | Slightly elevated but significantly reduced compared to no treatment |
| Treated after 1 year old | Moderate reduction in fertility potential | Moderate increase in cancer risk persists |
| No treatment (untreated) | Severe infertility common especially if bilateral | Cancer risk elevated up to 8 times normal levels |
| Bilateral cryptorchidism untreated | Mild-to-severe azoospermia (no sperm production) | Cancer risk highest among all groups |
| Unilateral cryptorchidism untreated | Mild reduction; contralateral testis may compensate partially | Cancer risk increased but less than bilateral cases |
Lifelong Monitoring: Why It Matters Even After Correction?
Even after successful orchiopexy during infancy or childhood, vigilance remains important throughout life:
- Cancer Screening: Men with a history of cryptorchidism should perform regular self-exams starting at puberty.
- Semen Analysis: Fertility evaluations might be necessary if conception difficulties arise later on.
- Testicular Health: Any new lumps, swelling, pain should prompt immediate medical evaluation regardless of past surgeries.
This ongoing care helps catch problems early when they’re easier to manage effectively.

Frequently Asked Questions
What Happens If Your Testicles Don’t Drop Naturally?
If your testicles don’t drop naturally by six months of age, they are unlikely to descend on their own later. This condition, called cryptorchidism, requires medical evaluation to prevent potential complications such as fertility issues and increased cancer risk.
What Are the Health Risks If Your Testicles Don’t Drop?
Undescended testicles can lead to fertility problems due to impaired sperm production. There is also a higher risk of testicular cancer and testicular torsion if left untreated. Early diagnosis and treatment reduce these risks significantly.
How Is Cryptorchidism Diagnosed When Testicles Don’t Drop?
Doctors examine newborns and infants to check if testicles have descended. If they haven’t dropped by six months, imaging techniques like ultrasound or laparoscopy may be used to locate the undescended testicle for proper diagnosis.
What Treatments Are Available If Your Testicles Don’t Drop?
Treatment often involves surgery called orchiopexy, which moves the testicle into the scrotum. Hormonal therapy may also be considered in some cases. Early intervention improves outcomes related to fertility and cancer prevention.
Can Undescended Testicles Affect Fertility If They Don’t Drop?
Yes, undescended testicles can impair sperm production due to higher internal body temperatures. Timely treatment helps preserve fertility potential by relocating the testicle to the cooler environment of the scrotum.
The Answer – What Happens If Your Testicles Don’t Drop?
Ignoring an undescended testicle can lead to serious problems such as infertility due to impaired sperm production and a significantly increased risk of developing testicular cancer over time. Early diagnosis followed by appropriate surgical correction greatly improves outcomes by placing the testes into their proper position where they can function optimally while reducing future health risks.
Parents noticing absent testes at birth should seek prompt medical evaluation rather than wait for spontaneous descent past six months—after which chances diminish sharply.
In summary:
- An undescended testicle disrupts normal reproductive function because it fails to reach its ideal temperature environment.
- Treatment options exist that restore anatomy and reduce long-term complications.
- Lifelong awareness remains vital even post-treatment due to residual cancer risks.
