Undescended testes (UDTs) are a relatively common finding in newborn males, especially in those born prematurely. Upon discovering a non-intrascrotal testis, it is important to determine whether the testis is palpable or non-palpable and whether the finding is unilateral or bilateral. Imaging should not be used in this workup, as no current modality has been shown to be adequately sensitive or specific to aid in management decisions. Patients with UDTs diagnosed after 6 months of age should be referred to a specialist for correction so that surgery may be performed within 1 year thereafter. This allows testes to descend spontaneously if they are to do so while facilitating early intervention to decrease the risk of subfertility and testicular malignancy for those patients in whom spontaneous descent does not occur.The surgical approach is often dependent on the location of the testis on physical exam. Most orchiopexies for palpable testes are performed through an inguinal incision, although a scrotal approach can be safely utilized depending on the testis position. Diagnostic laparoscopy is most often used for non-palpable testes, as it not only allows for the identification of an atrophic or absent testicle, but it also provides an opportunity to perform an orchiopexy simultaneously should a viable testis be found. Hormonal therapy is not recommended for treatment of UDTs due to its low success rate, the incidence of secondary re-ascent, and the possible detrimental effects on spermatogenesis. Finally, patients with bilateral non-palpable UDTs require a more extensive preliminary evaluation to rule out congenital adrenal hyperplasia (CAH) and disorders of sexual development (DSD). This involves serum electrolytes, karyotype analysis and hormonal testing including a serum müllerian inhibiting substance (MIS), in order to determine if testicular tissue is present and functional.
