Q

What male genital problem causes an increased risk of testicular cancer?

A

Cryptorchidism (40 times as likely to develop testicular CA)

(Most common genital problem encountered in pediatrics)

Q

How do you test for functioning testicular tissue?

A

Hormonal challenge: HCG will confirm the presence of functioning testicular tissue (hcg is virtually identical to Pituitary LH)

If the FSH is 3X normall and no increase in testosterone in response to hCG, functional tests are not present
