If severe may cause voiding problems.
Treatment
Term
Hypospadius
Definition
Urethral orifice is on the ventral surface of the penis
On the glans, minimal defect
13% unrethral opening on the penis shaft or penoscrotal area
chordee (penile bowing) is often present
Treatment
Surgery (multi-stage)
May use foreskin in repair so circumcision is contraindicated
Term
Undescended Testicles (Cryptorchidism)
Definition
Failure of testicles to descend into scrotum
May be absent (anorchia)
Must be distinguished from hyperactive cremasteric reflex (when it goes up back into the top of the scrotum)
May remain in inguinal canal or abdomen.
3% of newborn and 20%of premature males born with cryptorchidism
By age 1, 80% have descended into scrotum
Of those not is scrotum, 1/3 are retractile
Degeneration of sperm forming cells may occur if not corrected
Term
a female fetus is virilized (may be congenital adrenal hyperplasia- this can result in sudden death due to hypovolemic shock because they lose salt) or
a male fetus is incompletely masculinized.
Definition
two basic causes of intersex
Term

Definition
(XY)
