Summary

The fertility of the Sudanese population (North) is close to natural. The high observed fertility rate in Sudan is found to be a function of the high proportion married and ineffective family planning procedures. The main inhibitor is prolonged lactational amenorrhoea. The high level of fertility exists in spite of a low level of fecundability. The duration of separation between spouses, due to temporary or seasonal migration of husbands, and the pathological causes of high primary sterility, which contribute to the low fecundability, need further investigation.
