Prenatal exposure to PCBs impacts reproductive function in offspring

Prenatal exposure to the environmental contaminants polychlorinated biphenyls, or PCBs, causes long-term changes to the developing brain that have adverse effects on reproductive function later in life, a new study finds. Results will be presented Saturday at The Endocrine Society's 94th Annual Meeting in Houston.

IOF review outlines pathophysiology, diagnosis and management of osteoporosis in young adults

Much of the research defining osteoporosis and fracture risk has focused on older adults, i.e. postmenopausal women and men over the age of 50. While older adults are at highest risk of osteoporosis and related fractures, the disease can also affect younger adults between 20 and 50 years of age. However, the diagnosis and management of osteoporosis in young adults is complicated by special challenges, including a complex pathophysiology and the related fact that there is no clear definition of osteoporosis, or of intervention thresholds, in this age group.

Research with infant twins shows that environmental conditions determine testosterone levels

By comparing the testosterone levels of five-month old pairs of twins, both identical and non-identical, University of Montreal researchers were able to establish that testosterone levels in infancy are not inherited genetically but rather determined by environmental factors. "Testosterone is a key hormone for the development of male reproductive organs, and it is also associated with behavioural traits, such as sexual behaviour and aggression," said lead author Dr. Richard E. Tremblay of the university's Research Unit on Children's Psychosocial Maladjustment.
