Ovarian hyperstimulation syndrome in preterm infants

Area of Science:

• Reproductive Endocrinology
• Neonatal Medicine
• Pediatric Gynecology

Background:

• Estradiol-producing ovarian cysts are rare in neonates.
• Preterm infants may experience unique endocrine challenges.
• Understanding neonatal ovarian function is crucial for long-term health.

Observation:

• Four very preterm female infants presented with estradiol-producing ovarian cysts before their expected delivery date.
• Elevated serum estradiol concentrations were observed in affected infants.
• One infant underwent surgical cyst removal, while another was treated with medroxyprogesterone acetate.

Findings:

• Medroxyprogesterone acetate treatment led to decreased estradiol levels and cyst resolution.
• Two infants experienced spontaneous cyst disappearance and normalization of estradiol.
• Hormonal analysis revealed a transient postpubertal response to gonadotropin-releasing hormone in affected infants, normalizing to a prepubertal pattern later.

Implications:

• These findings suggest a potential role for hormonal interventions in managing neonatal ovarian cysts.
• Early identification and monitoring of estradiol-producing ovarian cysts are important in very preterm infants.
• The study highlights the dynamic nature of hormonal regulation in preterm neonates.
