Ovarian hyperstimulation syndrome treated by medroxyprogesterone acetate.

The activation of the hypothalamic-pituitary-gonadal axis observed during the first month of life is thought to be a significant phase in the maturation of gonads and potentially be important for the development of reproductive functions. The preterm ovarian hyperstimulation syndrome (POHS) was first detected at postconception 36-39 weeks in a preterm female newborn with edema developing in the vulva, the hypogastric site, and the upper leg. The pathophysiology of this postnatal hormonal change is obscure. In this paper we would like to present a case developing POHS and to discuss possible pathophyslogical mechanisms.
