No

Cutting edge research on human reproductive biology in the hothouse atmosphere of Silicon Valley is the focus of this last installment in Carl Djerassi's pioneering "science-in-fiction" tetralogy. Renu Krishnan is an Indian-born, American-educated scientist who discovers how "No" (nitric oxide) can help men with erectile dysfunction, which describes the research behind Viagra. At the same time, her husband, Israeli scientist Jephtah Cohn, develops a new approach to ovulation prediction, which again is based on current medical research. Djerassi brings back many characters from his three earlier novels for a satisfying conclusion in the high-stakes world of biotechnology.

Carl Djerassi is an internationally renowned scientist whose books include the novel Marx, Deceased; his autobiography The Pill, Pygmy Chimps, and Degas' Horse; essay, poetry, and short-story collections and two plays. A professor of chemistry at Stanford University, he is a member of the National Academy of Sciences and is one of the few American scientists to have been awarded both the National Medal of Science and the National Medal of Technology.
