Dr. Ethan Urquhart, Chief of Biology at the Sevarin District Reproduction Centre on Athos, is upset to find that his long-awaited shipment of ovarian tissue cultures from off-planet consists of an unusable mixture of dead and animal tissues. An exclusively male-populated planetary colony, continuing reproduction on Athos relies on uterine replicator technology, but the centuries-old cultures introduced by the original colonists have recently begun deteriorating into senescence. With their entire shipment purchased from the planet Jackson's Whole inexplicably consisting of genetic trash, the Population Council of Athos sends a reluctant Ethan offworld in search of a fresh batch of tissue cultures and (if possible) a refund from the original supplier, House Bharaputra. This is a very daring assignment as it means contact with women, who Athosians are taught are demonic and terrifying.
