Newborn vaginal leakage is caused by maternal hormones. Which hormone is most commonly associated with this phenomenon?

Explanation:
Maternal estrogen exposure after birth can produce transient vaginal discharge in newborns. Estrogen crosses the placenta and remains in the baby’s circulation for a short time, stimulating the vaginal mucosa and sometimes the breast tissue, which leads to a small vaginal discharge days to weeks after birth. This is a normal, self-limited finding as the maternal hormones are cleared. The other hormones listed aren’t typically linked to this phenomenon: progesterone, testosterone, and growth hormone don’t normally cause newborn vaginal leakage.
