According to recent research from the United States, "prolonged spaceflight results in bone loss in astronauts, but there is considerable individual variation. The goal of this rat study was to determine whether gender influences bone loss during simulated weightlessness. Six-month-old Fisher 344 rats were hindlimb unweighted for 2 weeks (wk), after which the proximal tibiae were evaluated by histomorphometry."
"There were gender differences in tibia length, bone area, cancellous bone architecture, and bone formation. Compared with ...
