In neonatal gynecomastia, some infants may also present with which finding?

• A. Jaundice
• B. Poor feeding
• C. Galactorrhea
• D. Fever

Answer: (C)

Neonatal gynecomastia is often the result of maternal estrogens crossing the placenta and briefly stimulating the infant’s breast tissue after birth. In some babies this hormonal milieu can also trigger galactorrhea—the milky discharge from the nipples—because estrogen and prolactin signaling promotes milk production even in newborns. This is typically temporary, resolving as maternal hormones clear and the infant’s own hormone levels normalize over days to weeks. Jaundice, poor feeding, and fever aren’t characteristic findings specifically linked to neonatal gynecomastia, though they may occur for other reasons in newborns.
