Pathogenesis and treatment of varicoceles

A mix-up over the references at proof stage of this editorial by Jay Sandlow (24 April, pp 967-8) led to some referencing errors. Firstly, in the reference list, reference 12 should be: Dohle GR, Pierik F, Weber RF. Does varicocele repair result in more spontaneous pregnancies? A randomised prospective trial [abstract]. J Urol 2003;169: 408. (This reference supports the penultimate sentence of the fifth paragraph.) Secondly, the reference list should contain a reference 13 (Schlesinger MH, Wilets IF, Nagler HM. Treatment outcome after varicocelectomy. A critical analysis. Urol Clin North Am 1994;21: 517-29), and the reference cited at the end of the first sentence of the sixth paragraph should be 13 (not 12).
