Question

Why is placenta previa more common in females?

Answer 1

Placenta previa is a condition of the uterus which is found only in the female of the species.

Explanation:

Placenta previa is a condition during pregnancy in which the placenta lies low in the uterus, partially or fully covering the cervical opening. It can result in bleeding if the placenta tears, complicate delivery, and, if major, necessitate a caesarean section.
