Does weight effect conception rates? What about body fat distribution?
There was a study published in the British Medical Journal that found that very lean women and very obese women (BMI >38) had lower conception rates. However, body fat distribution was found to have a greater impact. Women with a high waist-hip ratio had greater trouble conceiving — so being shaped like an apple is not as good for conception as being shaped like a pear. PCO women may be more likely to have the apple shape.
