The CDC and National Birth Defect Project studied the incidence of birth defects in the US. Key findings include: [citation needed] Down syndrome was the most common condition with an estimated prevalence of 14.47 per 10,000 live births, implying about 6,000 diagnoses each year. About 7,000 babies are born with a cleft palate, cleft lip or both.
Spina bifida (SB; / ˈ s p aɪ n ə ˈ b ɪ f ɪ d ə /; [9] Latin for 'split spine') [10] is a birth defect in which there is incomplete closing of the spine and the membranes around the spinal cord during early development in pregnancy.

It is the most common birth defect of the male genital tract. [1] About 3% of full-term and 30% of premature infant boys are born with at least one undescended testis. [2] However, about 80% of cryptorchid testes descend by the first year of life (the majority within three months), making the true incidence of cryptorchidism around 1% overall.
