9 Months That Made You is an American documentary/TV series created and produced by PBS. It showcases the conception of birth and fetal development, along with some mutations that is caused by certain circumstances during development.
With the help of CGI and personal stories, this three-part series documents the minute-by-minute process of human gestation, from conception to birth. Each episode looks inside the womb to re-create the growth process of a fetus, illustrating how a fertilized egg acquires traits that ultimately lead to the creation of a unique individual. The series also explains how certain unexpected mutations can occur during the growth process. One story focuses on a family whose multigenerational genetic mutation causes half of the members to grow six digits on each hand.
