title: Low testosterone levels in pre-term newborns born small for gestational age.
abstract: Previous studies showed that small for gestational age (SGA) newborns have an increased prevalence of hypospadias and other congenital defects of external genitalia. We observed that in the first days of life, SGA male pre-term newborns have reduced testosterone levels compared with adequate for gestational age pre-term newborns, independently from the presence of abnormalities of the external genitalia.
