The Second-to-Fourth Digit Ratio in Cryptorchidism: A Case-Control Study.

Purpose: The homeobox (Hox) genes a and d controlling limb and genital development influence the digit ratio and the fetal production of testicular androgen, which may result in testicular descent in boys. To assess whether the digit ratio reflects disease status, we investigated the second and fourth finger lengths in children with cryptorchidism, in children with hydrocele as a disease control, and in healthy controls (boys and girls).

Materials And Methods: One hundred ninety-six children (46 with cryptorchidism, 50 with hydrocele, 50 healthy boys, and 50 healthy girls) who were 6 to 23 months of age were prospectively enrolled.

Effect of patient-optimized doses of tamsulosin on erectile function in men with erectile dysfunction and lower urinary tract symptoms.

Purpose: To investigate the relationship of improvement in erectile function (EF) with improvement in lower urinary tract symptoms (LUTS) and to assess the contribution of tamsulosin dose to the improvement of EF apart from the indirect influence of LUTS improvement in men with LUTS and erectile dysfunction (ED).

Materials And Methods: Fifty patients received tamsulosin 0.2 mg/d for the first 4 weeks and were subsequently divided into two groups by patient-reported outcomes.
