Chemicals found in everyday products and food have subtle but potentially damaging effects on sperm fertility

Professor Lynn Fraser told the 21st annual conference of the European Society of Human Reproduction and Embryology today (Wednesday), that her previous research had shown that certain chemicals known to mimic the female sex hormone, oestrogen, could individually affect the correct functioning of mouse sperm, but now her new research showed that when the chemicals were combined they had an even stronger effect.

Early embryos with abnormal chromosomes are capable of returning to normal when grown in culture in the laboratory

While such embryos are not capable of developing into normal foetuses if implanted in a woman's womb, the discovery has important implications for stem cell production, especially in countries where the creation of embryos for stem cell research is discouraged or even banned.
