The demographic and genetic trajectory of the human sex ratio from conception to birth


23 March 2012

Presented by Dr Steven Orzack (Fresh Pond Research Institute, Cambridge, USA). Hosted by Associate Professor Peter Banks.

I describe the demographic and genetic trajectory of the human sex ratio from conception to birth by analyzing data derived from 1) three-day-old embryos, 2) induced abortions, 3) fetuses that have undergone chorionic-villus sampling or amniocentesis and 4) US census records of fetal mortality and live births. This data set is the most comprehensive and largest ever assembled to estimate the sex ratio at conception and the sex ratio trajectory and is the first to include all of these types of data. This analysis provides fundamental new insights into early human development. - Dr Steven Orzack
