title: A Rare Case of Ovarian Hyperstimulation Syndrome in a Preterm Infant.
abstract: Ovarian hyperstimulation syndrome is a rare disease among preterm infants. This syndrome was first described in 1985 in four infants with a gestational age of <30 weeks. Several explanations for this syndrome have been suggested namely the immaturity of Hypothalamic-Pituitary-Gonadal (HPG) axis, lack of negative feedback, increased sensitivity of Follicle Stimulating Hormone (FSH) receptors due to mutation and high level of estradiol. In this report, a case of hyperstimulation syndrome in a newborn with gestational age of 30 weeks is presented and the probable mechanisms in the literature are discussed.
