Abstract
The cover illustration of What Is Sex? features what is in this culture an instantly recognizable image. 1 Moonlike, an ovum hangs in the center against a black background. Off to the lower left a single sperm, its curved tail suggesting movement, points its head toward the egg. This image depicts a moment of anticipation, just before the merger of egg and sperm. As part of the cover illustration this image seems to function as the answer to the question posed by the title. The juxtaposition of the title and this image implies a definition of "sex" that is necessarily linked to reproduction and a fixed dual-gender system. This image of egg and sperm, which stands in for human females and males, suggests that when it comes to answering the question "what is sex?" human beings are central to the discussion.
