Chlamydia linked to ectopic pregnancies

Ladies may want to ensure their partners use condoms after scientists have suggested there is a link between ectopic pregnancy and chlamydia

Researchers at the University of Edinburgh discovered that women who have previously had the sexually transmitted infection (STI) are more likely to produce a certain type of protein in their fallopian tubes.

This increase in PROKR2 can make a fertilised egg more likely to implant in the tube and thus cause the baby to grow outside of the womb.

Dr Andrew Horne, of the University of Edinburgh's Centre for Reproductive Biology, said: "We know that chlamydia is a major risk factor for ectopic pregnancy but until now we were unsure how the infection led to implantation of a pregnancy in the fallopian tube."

The Ectopic Pregnancy Trust welcomed the findings and director Helen Wilkinson noted that the research would help to raise awareness of the importance of practicing safe sex.
