A new study based on a 20-year follow-up of one of the world's largest study cohorts, suggests that exposure to several factors in utero and in early life may lead to reduced semen parameters in adulthood and potentially to a decline in male fertility.

A study performed in Belgium has shown that low-cost IVF for developing and poor resource countries is feasible and effective, with delivery rates not much different from those achieved in conventional IVF programs. This proof-of-principle study, say the investigators, suggests that infertility care may now be "universally...

A new analysis has found that among patients with chronic lymphocytic leukemia, African Americans more commonly present with advanced disease, and they tend to have shorter survival times than Caucasians despite receiving the same care. Published early online in CANCER, a peer-reviewed journal of...

They're young. They've been injured in an assault - so badly they went to the emergency room. And nearly one in four of them has a gun, probably an illegal one. What happens next? A new study provides data that could be important to breaking the cycle of gun violence that kills more teens and young...

Researchers from Boston College and the Naval Research Lab report the potential for boron arsenide to challenge the extraordinarily high thermal conductivity of diamond, which could pave the way for a more plentiful and affordable alternative to cooling high tech devices. Fuente :...
