Einsam in Manhattan (1999)

At age 19, a young woman is jilted at the altar. This leads to a declaration that she will swear off men forever. Now 10 years later, she suddenly decides she would like to have a child. She advertises in the newspaper for potential mates, whether by traditional methods or by sperm donors, but gets nothing but losers. However, two neighborhood men vie for her attention - her gynecologist and a professional clown.
