| Annotation | Female life expectancy in developed countries has increased by 30 years in the twentieth century. The authors analysed age-specific fertility data from birth statistics for the USA, Canada, Japan, France, Sweden, the UK and Australia. Since 1940, birth rates for women aged 35 and over have declined. Among women aged 50 and over, there has been no increase in births. Fertility rates in 1990 were 0.0 to 0.044 per 1000 women, with total numbers ranging from 0 to 60 births per 1000. The fertile years have not been prolonged in the cohort of women whose life expectancy has increased so dramatically in the 20th century. This suggests that reproductive senescence is tightly controlled and not extended by factors that enhance female longevity. Other physiological mechanisms may also be fixed within narrow age limits.
