'Lie still' for pregnancy boost
Women undergoing fertility treatment with artificial insemination may boost their chances of pregnancy if they lie still afterwards, a study shows.
Researchers found 27% of women who lay down for 15 minutes after the procedure went on to have a baby compared with 17% who got up and moved around.
Writing in the British Medical Journal, the researchers said lying down may prevent "leakage" of sperm.
Study leader Dr Inge Custers from the Academic Medical Center in Amsterdam said the results had prompted clinics in the Netherlands to rearrange their clinics to allow women to remain laid down for quarter of an hour after their treatment.
