newborn screening programme


While in the womb, male babies' testicles develop in their abdomen. Towards the end of pregnancy, the testicles travel down into the scrotum. Both testicles should be in the scrotum by the time the child is one year old. If this is not the case, the testicles are described as being ‘undescended’. This is also known as cryptorchidism.
