Protocol - Male Reproductive Tract Birth Defects
The male participant answers whether he was ever diagnosed with Cryptorchidism, Hypospadias and/or other related conditions.
The questions were originally asked of partners of pregnant women but the WG recommends asking them of adult males.
Note: Cryptorchidism is failure of one or both of the testes to descend into the scrotum. Hypospadias is a developmental anomaly in which the male urethra opens on the underside of the penis or on the perineum.

Mode of Administration
The presence of these physical conditions is often associated with abnormalities of androgen production such as Kallmann’s Syndrome and 5 alpha reductase deficiency, and may be associated with certain chemical exposures in utero. The Study for Future Families’ protocol was selected because it specifically addresses physical exam findings.

Process and Review
The Expert Review Panel #5 (ERP 5) reviewed the measures in the Reproductive Health domain.
Guidance from ERP 5 includes:
· Revised descriptions of the measure
- Spelling of hypospadias corrected throughout measure

Male Reproductive Tract Birth Defects
February 26, 2010
Questions to determine whether a male participant has ever had certain conditions that could have developed in utero. Cryptorchidism is failure of one or both of the testes to descend into the scrotum. Hypospadias is a developmental anomaly in which the male urethra opens on the underside of the penis or on the perineum.
The purpose of these questions is to determine whether the participant had ever had the following abnormalities that developed in utero: Cryptorchidism, Hypospadias, and/or other related conditions. These conditions are suspected of being hereditary and/or influenced by environmental factors, may reflect abnormalities of androgen production, and may be passed to offspring.
