Ideal vs. real: revisiting contraceptive guidelines.

This commentary focuses upon an article about the ethical use of contraception in research involving human participants. It states that it agrees with the central points of the paper but takes issue with the characterization of the proposed policy and with the implications of some of the terminology employed. This piece seeks to clarify the position and motivation of the authors and describe several experiences that have resulted from the implementation of the policy at the University of Nebraska Medical Center.
