162. Issa, Y., , Sallman,M., Nijem,K., Bjertness,E., Kristensen ,P. Fecundability in newly married couples in agricultural villages in the occupied Palestinian territory: a prospective study. 2010

Estimates of fecundability have varied from 015 to 030 in prospective studies undertaken in high-income countries. The validity of these studies has been questioned, and the complexity of societal and cultural factors in high-income settings makes dissection of biological effects difficult. Prospective study of newly married couples in the Palestinian population provided a good opportunity to obtain an unbiased estimate of fecundability. a prospective study of time to pregnancy was undertook  in all newly married couples in two Palestinian agricultural villages between May, 2005, and August, 2007.
