Patterns of reproductive failure described in humans and other mammals suggest that reproductive failure may in many instances
be the result of adaptations evolved to suppress reproduction under temporarily harsh conditions. By suppressing reproduction
under such conditions, females are able to conserve their time and energy for reproductive opportunities in which reproduction
is most likely to succeed. Such adaptations have been particularly important for female mammals, given (a) the amount of time and energy that reproduction requires, and (b) the degree to which reproductive conditions can vary.
The existence of conscious and unconscious mechanisms to suppress reproduction under poor conditions has several implications
for obstetric/gynecologic practices. Two implications are discussed with reference to biotechnological advancements in our
ability to facilitate conceptions and manage problem pregnancies: (a) potential dangers of sophisticated technologies overriding natural fertility controls; and (b) the need for greater appreciation of the association between psychosocial stress and reproductive failure in the treatment
of reproductive problems. Implications for elective abortion practices are discussed as well.
The ideas for this paper were developed while the author was a recipient of a Career Development Award from the Harry Frank
Guggenheim Foundation.
Dr. Wasser received a B.S. degree of Zoology from Michigan State University in 1975, a Masters of Science in Zoology from
the University of Wisconsin-Milwaukee in 1976, and a Ph.D. in Psychology from the University of Washington in 1981. He is
co-director of the Animal Behavior Research Unit, a long-term study on the behavioral ecology and reproduction of free-ranging
yellow baboons at Mikumi National Park, Tanzania. Dr. Wasser’s primary research focus is on the evolution of reproductive
strategies in female mammals. His work includes research on human infertility and abortion. He is also working on the breeding
of endangered species in captivity under a Research Development Award from the National Zoological Park of the Smithsonian
Institution. 相似文献

Numerous environmental and host factors, some of which are known and some unknown, contribute to cancer development. While data and studies abound, our current understanding of the relation between cancer and the environment is still very limited. Understanding environmental carcinogenesis is critical to its effective management. Biotechnology has revolutionalized the study of biological and biomedical sciences. This minireview provides an overview of environmental carcinogenesis with emphasis on the contributions and prospects of biotechnology in advancing an understanding of environmental carcinogenesis for its prevention and intervention. 相似文献
