Abstract
ObjectiveThe incidence of disorders of sexual development (DSD) is unknown in sub-Saharan Africa. We describe the characteristics and incidence of DSD in a cohort of infants born in Ghana.DesignTrained research assistants performed systematic genital examination at birth. All infants with suspected abnormal genitalia were further examined by a paediatric endocrinologist.SettingKomfo Anokye Teaching Hospital, Kumasi, Ghana.PatientsConsecutive infants born in a single centre over a 1-year period (May 2014 to April 2015).Main outcome measuresIncidence of DSD. Micropenis was defined as a stretched length <2.1 cm and clitoromegaly as a clitoral length >8.6 mm.ResultsWe examined 9255 infants (93% of all live births) within 72 hours of birth. Twenty-six neonates had a DSD. Nineteen infants had DSD without genital ambiguity: isolated micropenis (n=2), hypospadias (n=7), cryptorchidism (n=4) and clitoromegaly (n=6). Seven infants had DSD with ambiguity: clitoromegaly with a uterus on ultrasound and elevated 17-hydoxyprogesterone, suggesting XX DSD due to congenital adrenal hyperplasia (CAH)(n=4) and micropenis, hypospadias and gonads in a bifid scrotum or in the inguinal region, consistent with XY DSD (n=3).ConclusionThe incidence of atypical genitalia was 28/10,000 (95% CI 17/10 000 to 39/10 000) live births. The incidence of CAH was 4.3/10 000 (95% CI 1.2/10 000 to 11.1/10 000) and was strongly associated with consanguinity.
