3. Hypospadias:
is a birth defect of the male urethra that results in
the urethral meatus (opening) being positioned in
an abnormal location on the ventral aspect of
the penis.
4. Incidence:
Hypospadias occurs in 1 in every 300 male children
.
There is an increased incidence of undescended
testicles in children with hypospadias.
8. Risk factors:

2-Fertility treatments:
3-certain hormons
Mothers who were age 35 years or older and who were
considered obese had a higher risk of having a baby with

necessitates voiding in the sitting position
caused by deficient or absent ventral
foreskin
14. Investigations:
1-Karyotyping and buccal
smear
children with penoscrotal and perineal hypospadias often have
a bifid scrotum and ambiguous genitalia
2-Urethroscopy and cystoscopy
to determine whether internal male sexual
organs are normally developed
3-Excretory urography
to detect additional congenital anomalies of the kidneys and ureter
15. Treatment:
depends on the type of defect the boy has. Most cases of
hypospadias will need surgery to correct the defect.
between the ages of 3โ18 months old.
