Scientists report that the use of scented creams and perfumes could increase the risk of unborn boys developing infertility later in life.
The team of researchers at Edinburg University determined that building blocks for future reproduction were developed within a 12 week period during the pregnancy. It is during this time they say developing infants may be more influenced by chemicals found in cosmetics.
The research team led by Professor Richard Sharpe of the Medical Research Council’s Human Reproductive Sciences Unit, based in Edinburgh admitted that these preliminary results still require more conclusive proof.
Researchers conducted tests on laboratory rats. They blocked the action of androgens, which include male sex hormones such as testosterone.
The experiments confirmed that if the hormones are blocked, the animals suffered fertility problems.
Many of these hormone-blocking chemicals can be found in such items as cosmetics, household fabrics and plastics.
Prof Sharpe said the chemicals may also increase the risk of baby boys developing other reproductive conditions in later life, including testicular cancer.
“There are lots of compounds in perfumes that we know in higher concentrations have the potential to have biological effects, so it is just being ultra safe to say that by avoiding using them your baby isn’t at risk.
“If you are planning to become pregnant you should change your lifestyle. Those lifestyle things don’t necessarily mean that you are going to cause terrible harm to your baby, but by avoiding them you are going to have a positive effect.
“We would recommend you avoid exposure to chemicals that are present in cosmetics, anything that you put on your body that might then get through your body into your developing baby.
“It is not because we have evidence that these chemicals categorically cause harm to babies, it is only based on experimental studies on animals that suggest it is a possibility.”
Prof Sharpe is due to unveil his findings next week at the Simpson Symposium in Edinburgh, a gathering of fertility experts organized by Edinburgh University.
