Professor Alison Murdoch, who prospects the Newcastle group, says the HFEA’s decision was ‘a step forward for stem cell analysis and medication generally’ but she also says ‘it is of paramount importance to ensure that all donors aren’t recruited to take part in this study against their best interest by coercion or extreme financial inducement.’ Professor Murdoch says there have been many scientific problems to be overcome before the research led to stem cell treatments and admits it really is ‘unusual’ for the HFEA to begin with a consultation after issuing a licence. Some professionals are surprised by the move and state even though there is a dependence on eggs for analysis the licence is usually inconsistent with the theory of not spending money on eggs for research.For the new analysis, Li and colleagues studied 164 factory workers in China who had been exposed to high degrees of BPA face to face. They were in comparison to 386 other guys in the same town who either proved helpful at various other factories or were wedded to factory workers. The scientists measured BPA exposure through atmosphere sampling, and interviewed the workers about their sexual functioning. When compared to other workers, guys with high BPA exposure were about four situations as more likely to report trouble achieving erections, about seven occasions as more likely to say they had problems ejaculating, and about four times as likely to record low sex drive or low fulfillment with their sex lives. The effects are dramatic and clearly linked to the exposure ‘fairly,’ said Linda Birnbaum, director of the National Institute of Environmental Health Sciences, who was simply not mixed up in research.
