A hypothesis on the increasing rates of ectopic pregnancy

Paediatric and Perinatal Epidemiology, 1989

There is evidence that women with ectopic pregnancies have low oestrogen levels and that tubal contractions are under oestrogenic control. Low diets and vigorous exercise both lower women's oestrogen levels.
