PURPOSE: Natural dizygotic twinning (DZT) results from hyper-ovulation and is an indicator of female fertility. However, some traits linked to DZ twinning are also associated with infertility. We examined the relationship between DZT and fe…

Natural dizygotic twinning (DZT) results from hyper-ovulation and is considered an indicator of female fertility. DZT has low polygenicity, with only 0.20% of SNPs estimated to have a nonzero effect. A polygenic score (PGS) for DZT explains…

Identifying genetic determinants of reproductive success may highlight mechanisms underlying fertility and identify alleles under present-day selection. Using data in 785,604 individuals of European ancestry, we identified 43 genomic loci a…

The genetic architecture of human reproductive behavior-age at first birth (AFB) and number of children ever born (NEB)-has a strong relationship with fitness, human development, infertility and risk of neuropsychiatric disorders. However, …
