ABSTRACT
Objective To establish a rabbit model of hypospadias finasteride to further stadying molecular mechanisma of hypospadias etiology. Methods forty pregnant new zealand rabbits were randomly divided into five groups. Finasteride was fed with 0days(group A), 4 days (group B), 5 days (group C), 6 days (group D), 7 days (group E) which began at GD(gestation days) 19, 10 mg?kg-1?d-1. The appearance of penis and the position of urethras orifice were exmamined to observe hypospadias on postnatal day 35; the second observation was performed to observe retained testicle and the Severity of hypospadias on postnatal day 70, all of the male rabbits were anatomized to observe the development of didymus. Results Hypospadias was seen in group A(0)、group B(22.2%)、group C(95.5%)、group D(85.2%)、group E(100%),and Severity of hypospadias can be divided into 3 degrees. Retained testicle was seen in group A(0)、group B(0)、group C(36.4%)、group D(40.7%)、group E(73.3%). Conclusions The experimental model of hypospadias induced by finasteride is stable.
