"As well as potentially helping women who are finding it difficult to get pregnant, a better understanding of the way fallopian tubes work will help doctors treat pelvic inflammation and sexually transmitted disease more successfully," said Ward. "It could also increase our understanding of what causes ectopic pregnancy, an extremely painful and potentially life-threatening situation in which embryos get stuck and start developing inside a woman's fallopian tube."
