The genetic basis of fertility, family and longevity Led by researchers from the University of Oxford’s Leverhulme Centre for Demographic Science and the University of Iceland, the review explores how genetic variations can explain differences in reproductive health and longevity. The study provides the most comprehensive review of male and female genetic discoveries of reproductive traits to date, and provides new insights into how our DNA affects when we have children, the timing of menopause, and even how that is connected to how long we live. Genes at the heart of reproduction Using the GWAS Catalog , an online database of Genome Wide Association Studies (GWAS), the researchers identified 159 genetic studies and 37 key genes that are linked to reproductive traits such as age at first childbirth, menopause timing, and hormones such as follicle-stimulating hormone (FSH) and testosterone. These findings suggest that genetic factors play a significant role in broader health outcomes a...
