The investigator will collect data on penile and glans size by age, weight and ethnicity in both patients undergoing routine urological surgery and hypospadias surgery.

After obtaining informed consent , the investigator will measure stretched penile length and glans size in 3 dimensions (length, width, height) in the office on patients with hypospadias, as well as at the time of operation, after the induction of anesthesia. Patients undergoing hypospadias surgery will be considered study subjects. If the patient was given pre-operative testosterone as part of the current standard of care, this will be noted and the measurements taken at each pre-operative office visit will be recorded. The investigator will also record corrected age, weight in kilograms and ethnicity as identified by the family.

Control patients will be those male patients undergoing non-hypospadias urological surgery (hernia repair, orchiopexy, circumcision, re-circumcision) with a normal penis, the investigator will perform a single intra-operative measurement of the same glans and penile variables after induction of anesthesia and prior to the start of their genital surgery. Again, age, weight and ethnicity will be recorded.

Inclusion Criteria:

• Patients undergoing surgery for hypospadias
• Patients undergoing any urologic surgery other than hypospadias

Exclusion Criteria:

• other penile abnormalities (Hidden penis, penoscrotal wedding/transposition, chordee without hypospadias, penile torsion, etc.)
• Undergoing other penile procedures (penoplasty, chordee repair, penile detorsion, etc.)

The source of subjects will be patients examined in the Pediatric Urology clinic and operating room. In contemporary practice, most hypospadias surgery is conducted at less than two years of age. Total of patients enrolled will be 90, with 45 in each the control and study group. The study population are patients undergoing surgery for hypospadias and the control population are patients undergoing any urologic surgery other than hypospadias.
