The scrotum forms by fusion of the fetal labioscrotal folds
under the influence of dihydrotestosterone between 8-16 weeks of gestation.
The labioscrotal folds
were separated, phallus length was 1.
As a result, there is no fusion of the genital folds to form scrotum and penis and no posterior migration of the labioscrotal folds
Although hypospadias may be suspected during the early second trimester or even the first half of pregnancy, a diagnosis at this time may be erroneous because the fusion of the labioscrotal folds
in a male fetus may be delayed.
Key feature in physical examination is the presence of gonads in labioscrotal folds
or inguinal canal.
