A baby boy turned out to be a girl one month after being born to a couple in South Africa.
The baby appeared to have male genitals at birth and even doctors confirmed he was a boy.
Four week after the birth, mum Madeleshia and hubby Kenneth sensed that something was wrong and took their baby to hospital where after some tests it was confirmed that the baby was a female.
Toddler, Kenny Hiscock, had enlarged organs because of a rare enzyme deficiency, which causes abnormal hormone production.
The couple has now renamed Kenny as McKenzi and are considering surgery.
"The doctor told us McKenzi is not really male or female, but somewhere between," the Sun quoted the mother as saying.
"But we have a beautiful daughter, and we're both incredibly proud," she said.
