Campbell Lab Focus
The focus on defining the physiological factors giving rise to
interpopulation variations in realized fertility in humans and the
development of tools for assessments of these factors.
This work has helped found the
discipline of human reproductive ecology which also includes
examination of factors that link diet and disease status to such
pertinent phenomena as birth seasonality, male endocrine function, and
female conceptive loss. Exploration of the reproductive biology of a captive
prosimian and the effects of diet on steroid catabolism in other
species has expanded applications of our methods beyond humans.
In vitro studies of the measurement and metabolism of several hormones
including steroids, gonadotropins and inhibin and molecular genetic
of disease vectors, immune status, female reproductive status and
patterning both in human and nonhuman species have expanded the
available for study. Development of methods for simultaneously
and noninvasively measuring ovarian, insemination and urogenital
microbial ecology status in serial female urine sediments has expanded
the abilities of demographers, epidemiologists and clinicians
conducting fertility enhancements.
Ultimately our work should help define which physiological and ecological parameters are most appropriate for modulation in programs meant to empower couples to regulate the size and spacing of children as well as those most vulnerable to insult and therefore in need of protection with environmental, animal management, public health, nutrition, or care delivery programs.
