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.

Difference in glans size between hypospadias patients and those without hypospadias
The investigator will prospectively collect data on glans size by age, weight and ethnicity in both patients undergoing routine urological surgery and hypospadias surgery
Time frame: 6 months
Difference in penile length between hypospadias patients and those without hypospadias
The investigator will prospectively collect data on penis length by age, weight and ethnicity in both patients undergoing routine urological surgery and hypospadias surgery
Time frame: 6 months
Track penile and glans growth curves in both cohorts
The investigator will prospectively track penile and glans growth over time to develop longitudinal growth curves in both cohorts
Time frame: 24 months
Determine the effect of testosterone on penile and glans growth in hypospadias
The investigator will measure the glans size and penile length of patients who receive testosterone for small glans size before and after administration in order to determine the effect of testosterone administration.
Time frame: 24 months
