cryptorchidism

Cryptorchidism, also known as undescended testes or hidden testis, refers to a condition where one or both testicles fail to descend into the scrotum during fetal development or early childhood.

Causes and Features

• Cryptorchidism can occur due to various reasons, including hormonal imbalances, genetic factors, or environmental influences [1].
• Common features of cryptorchidism include undescended testes, which may be located in the abdomen or groin area [2].
• Some individuals with cryptorchidism may also experience other symptoms such as speech impairment, clinodactyly (a curved fifth finger), and visual disturbances [3].

Definition and Diagnosis

• Cryptorchidism is defined as the failure of one or both testes to descend into the scrotum [4].
• The condition can be diagnosed through a physical examination when one or both testes are not present within the dependent portion of the scrotal sac [5].

Prevalence and Risks

• Cryptorchidism affects approximately 3-4% of full-term male infants, with higher rates in premature babies [6].
• Individuals with cryptorchidism may have an increased risk for developing testicular cancer [7].

Cryptorchidism, also known as undescended testicles, is a condition where one or both testicles do not descend into the scrotum during fetal development. The signs and symptoms of cryptorchidism can vary in severity and may include:

• Empty scrotal sac: One or both testicles are missing from the scrotum, making it appear empty.
• Swelling in the groin: Swelling or inflammation in the inguinal area, which is the region where the testicles normally descend.
• Acute abdomen: Severe abdominal pain that can be a sign of an underlying condition such as hernia or testicular cancer.
• Heavy bleeding at the surgical site: This can occur if surgery is performed to correct the undescended testicle.
• Signs of infection: Skin discoloration, fever, chills, or fatigue can indicate an infection in the affected area.

It's worth noting that some babies with cryptorchidism may not show any noticeable symptoms other than an empty scrotum. However, if left untreated, undescended testicles are linked to a range of health problems and conditions, including hernia, testicular cancer, and infertility [1][2].

In addition to these physical symptoms, cryptorchidism can also be associated with other conditions such as:

• Testicular asymmetry: A condition where the testicles are not symmetrical in size or shape.
• Scrotal hypoplasia or asymmetry: A condition where the scrotum is underdeveloped or asymmetric.
• Retractile testis: A condition where the testicle can be felt in the inguinal canal but not in the scrotum.
• Ascending cryptorchidism: A condition where the undescended testicle is located above the inguinal canal.

Early detection and treatment of cryptorchidism are essential to prevent long-term complications [3][4].

Diagnostic Tests for Cryptorchidism

Cryptorchidism, also known as undescended testicles, can be diagnosed through a combination of physical examination and laboratory tests.

• Physical Examination: The diagnosis of cryptorchidism is typically made by a careful genital physical examination. A warm environment, warm examiner's hands, and a relaxed patient are important to avoid stimulating the child unnecessarily [6]. In most cases, the condition can be diagnosed during a routine checkup with a primary care provider [9].
• Ultrasound: Ultrasound is an appropriate screening evaluation for children with ambiguous genitalia or hypospadias and cryptorchidism [2]. This test can help identify any abnormalities in the reproductive system.
• Laboratory Studies: Laboratory tests may be ordered to rule out other conditions that may be causing the undescended testicle. These tests include:
  • LH (Luteinizing Hormone) testing
  • FSH (Follicle-Stimulating Hormone) testing
  • Testosterone testing before and after stimulation with human chorionic gonadotropin (hCG) [5]

It's worth noting that surgery may be needed to find the problem and treat it, especially if the condition is not diagnosed early on [1]. However, in many cases, a physical examination alone can provide enough information for a diagnosis.

Treatment Options for Cryptorchidism

Cryptorchidism, also known as undescended testes, can be treated with either surgical or hormonal therapy. The choice of treatment depends on the age and health status of the child.

• Hormonal Therapy: Human chorionic gonadotropin (hCG) is a hormone that stimulates the testicles to descend. It has been used for many years in the treatment of cryptorchidism, with varying degrees of success [1]. However, its use has declined in recent years due to concerns about potential side effects and the availability of more effective surgical treatments.
• Surgical Therapy: Orchiopexy, also known as orchidopexy, is a surgical procedure that involves repositioning the undescended testicle into the scrotum. This surgery has a high success rate, with most children experiencing complete descent of the testicles [2]. The current standard of therapy in the United States is orchiopexy, and it is considered the most effective treatment for cryptorchidism [3].

Medications Used to Treat Cryptorchidism

Several medications have been used to treat cryptorchidism, including:

• hCG: This hormone has been used to stimulate testicular descent in children with cryptorchidism [4].
• Pregnyl: This is a brand name for hCG and has been used to treat prepubertal cryptorchidism [5].

When Surgery or Hormone Therapy May Be Necessary

If the testicles do not descend on their own within six months, surgery or hormone therapy may be necessary. In some cases, multiple treatments may be required before a successful outcome is achieved.

Differential Diagnosis of Cryptorchidism

Cryptorchidism, also known as undescended testicle, can be confused with other conditions that may present similar symptoms. The differential diagnosis for cryptorchidism includes:

• Exaggerated cremasteric reflex: This is a condition where the cremaster muscle contracts excessively in response to stimulation, causing the testis to retract into the abdomen. This can simulate cryptorchidism and requires careful examination to distinguish between the two conditions [8].
• Other causes of testicular absence or non-descent: These may include congenital anomalies such as testicular aplasia (absence) or ectopia (abnormal location), which can also present with undescended testes.
• Hormonal imbalances: Certain hormonal disorders, such as hypogonadism or hypergonadotropic hypogonadism, can affect the development and descent of the testes.

Key Points to Consider

• A thorough physical examination is essential in diagnosing cryptorchidism and ruling out other conditions that may present similar symptoms.
• The cremasteric reflex should be carefully evaluated to distinguish between an exaggerated response and true cryptorchidism.
• Other causes of testicular absence or non-descent, as well as hormonal imbalances, should also be considered in the differential diagnosis.
