"Research has found the reproductive system of male foetuses could be damaged by chemicals as early as eight weeks' gestation by chemicals including those found in cosmetics.
Such damage could lead to infertility or testicular cancer, according to the research carried out on rats by Professor Richard Sharpe, principal investigator at the Medical Research Council's Human Sciences Unit.
The scientist said he had discovered a "time window" of eight to 12 weeks' gestation, when certain hormones in the foetus are activated and the male reproductive system comes into being.
Prof Sharpe said future problems of male fertility, including undescended testicles, low sperm count and the risk of testicular cancer could be determined at this time if these hormones, such as testosterone, do no work properly."
