But in men trying for a baby, peaks in testosterone coincided far more often with periods of intense sexual activity, New Scientist magazine said.
London (Reuters): Wannabe rock stars thrashing away on their electric guitars often drive their neighbours to distraction but they could be doing themselves an injury, say British researchers. A study undertaken at the University of Surrey found that young and inexperienced electric guitar players could develop musculoskeletal problems because of their poor posture and excessive grip on the strings.
