Understanding Unilateral Intraabdominal Testis

Unilateral intraabdominal testis is a medical condition that affects the testicles, causing one of them to remain in the abdomen instead of descending into the scrotum. This condition is also known as cryptorchidism and is common in newborn males.

During fetal development, the testicles form inside the abdomen and then descend into the scrotum before birth. However, in some cases, one or both testicles may not descend, leading to cryptorchidism. This condition affects approximately 3% of full-term male infants and up to 30% of premature male infants.

Symptoms of Unilateral Intraabdominal Testis

The most common symptom of unilateral intraabdominal testis is the absence of one testicle in the scrotum. In some cases, the affected testicle may be palpable in the groin area or the lower abdomen. However, in other cases, the testicle may not be easily detected during a physical exam.

Causes of Unilateral Intraabdominal Testis

The exact cause of unilateral intraabdominal testis is not known. However, several factors may contribute to this condition, including genetic factors, hormonal imbalances, and intrauterine factors such as fetal growth restriction and maternal smoking during pregnancy.

Diagnosis of Unilateral Intraabdominal Testis

Unilateral intraabdominal testis can be diagnosed during a routine physical exam. If the testicle is not palpable in the scrotum, the doctor may perform an ultrasound or MRI to locate the testicle. In some cases, a laparoscopy may be necessary to locate the testicle and determine if it is viable.

Conclusion

Unilateral intraabdominal testis is a common condition that affects newborn males. While it may not cause any symptoms, it is important to diagnose and treat this condition to prevent complications such as infertility and testicular cancer. If you suspect that your child may have unilateral intraabdominal testis, consult your doctor for an evaluation.
