Street Corner (1948)

"A forthright, true as life story of delinquent parents; a daughter who got into trouble and desperately sought the way out."

Naive small-town girl gets pregnant on her prom night, and winds up in the clutches of the local abortionist. Depending on the release presentation, the movie includes an animation of conception, filmed vaginal and caesarian section births, and a filmed presentation on how syphilis and gonorrhea present themselves.
