The two devised a computer program to simulate the effects of mutation accumulation and parasitism, which bears out the strength of their model. That this stigma comes hand in hand with difficulties in obtaining research funds is a reason that many are reluctant to classify themselves as sex researchers, say scientists like Howard Ruppell, executive director of the Society for the Scientific Study of Sex, headquartered in Mount Vernon, Iowa, and an adjunct professor of social work at the University of Iowa, and James Weinrich of the department of psychiatry at the University of California, San Diego. But obtaining grants for conducting such studies is often difficult, he says, citing the example of a study by Richard Udry of the University of North Carolina, Chapel Hill, aiming to survey adolescent sexual behavior patterns. This study had received funding from the National Institute of Child Health and Human Disease in May 1991, but was almost immediately canceled by Louis Sullivan, then the Secretary of Health and Human Services, on the grounds that it would undermine the administration's message to teenagers to not engage in sex. Allerand at Columbia University's Center for Reproductive Sciences in New York, while working on aspects of the reproductive system, do not see themselves as sex researchers.
Sex research has more to do with behavioral studies and surveys.
