Lord Winston, a leading UK fertility expert from
Imperial College in London, has caused great controversy in
his field by questioning the association of chlamydia with
infertility. In an interview reported this week, he said that
the growing incidence of subfertility is, in most cases, the
result of women delaying childbirth until after they are 35
years old, rather than a consequence of infection with the
sexually transmitted disease.

"I'm going to be very awkward about this. I think the evidence
that chlamydia affects fertility is very dubious," said Lord
Winston. "I haven't seen any figures that demonstrate that
it is causing infertility. Most infertility is not due to chlamydia."
He
claimed that the purported link between chlamydia and fallopian
tube damage is based on data from two Swedish studies conducted
in the 1960s, and that it has not been demonstrated since.
However, other fertility specialists have dismissed his claims. "It's
nonsense. There's no question the commonest cause of tubal
infertility is chlamydia," commented Sarah Gill from St. Mary's
Hospital in Paddington, London. "It's the commonest reason
for IVF."
