The influence of consanguinity on fertility and infant mortality in Sanabria (Zamora, Spain).
"The effects of consanguinity on fertility and infant mortality are studied in the population of the Sanabria Valley (Zamora province, Spain).  The sample is made up of 965 complete families, 100 couples being first cousins (FC), 172 second cousins (SC) and 693 non-related (NR).  There appears little difference in the fertility of consanguineous and unrelated couples but infant mortality rates (endogenous and exogenous) are higher among the offspring of consanguineous couples."
