Hypospadias, cryptorchidism and common male genital disorders: Case

Clinical case of a boy with a left palpable undescended testis and a distal hypospadias, covering the clinical assessment, the no-circumcision rule, the disorder-of-sex-development considerations, the germ-cell rationale for the orchidopexy window, and the long-term fertility and cancer surveillance.

Prompt
A 7-month-old boy is reviewed in the paediatric outpatient clinic. He was born at term by normal vaginal delivery, and the newborn examination had noted a left undescended testis that was expected to descend on its own. The mother now reports that the left testis has never been seen in the scrotum. On examination in the warm room the urethral meatus opens on the glans in a slightly ventral position with a hooded prepuce, the right testis is normally located in the scrotum, and the left testis is palpable in the inguinal canal but cannot be brought into the scrotum. The growth and development are normal, and there is no family history of note.

This boy has two findings that together change the management. The left testis, still palpable in the inguinal canal and not in the scrotum at seven months, is a true undescended testis that will not now descend spontaneously and needs orchidopexy within the 6 to 18 month window. The ventral glanular meatus with the hooded prepuce is a distal hypospadias, and its coexistence with the undescended testis raises the question of a disorder of sex development and absolutely forbids circumcision. [9] [1]

Clinical findings

The key findings are the palpable undescended left testis that cannot be milked into the scrotum, which distinguishes it from a retractile testis that would stay down once brought to the bottom of the scrotum, and the distal hypospadias with the hooded prepuce and the slightly ventral meatus. [1] The examination was correctly performed in the warm room in the frog-leg position, which relaxes the cremaster and is the essential precondition for an accurate assessment of testicular position in the infant. [9]

The coexistence of the two findings is the clinically important point. A hypospadiac meatus together with an undescended testis raises the probability of an underlying chromosomal or endocrine abnormality, and although this boy has a unilateral and palpable testis rather than the more worrying bilateral non-palpable presentation, the combination still warrants consideration of a disorder of sex development and discussion with the urology and endocrinology teams. [9]
