A Yale University student’s controversial art project that she says includes images of her inducing her own abortions is not part of an exhibit of undergraduate work that opened today on the campus, a spokesman for the institution said.

The project by Aliza Shvarts, a senior, was to have been part of a show of senior art projects that is scheduled to run in a campus gallery through May 1. The project has drawn fierce criticism and a few defenders in the days since word of the artwork was disclosed in a student newspaper.

Peter Salovey, dean of Yale College, issued a statement on Monday saying that before Ms. Shvarts’s work could be part of the exhibit, she would have to acknowledge that the abortions were “fiction.” He said she would have to submit a “clear and unambiguous written statement” saying that “she did not try to inseminate herself and induce miscarriages, and that no human blood will be physically displayed in her installation.”

Ms. Shvarts has repeatedly told the student paper, the Yale Daily News, that the abortions were real, while apparently telling Yale administrators that they never happened and that her work is “performance art.” Ms. Shvarts told the student newspaper that her project would include a large cube hanging from the ceiling that would be wrapped in sheets containing blood from the abortions she said she had induced in her bathroom. She also said she would project video images of the abortions onto the cube.

Tom Conroy, the Yale spokesman, said today that the question of whether Ms. Shvarts would agree to Mr. Salovey’s conditions had not yet been resolved. —Robin Wilson
