The human sexual condition questioned  by a theory! 

An interesting article published in Fertility and Sterility titled Sex and gender: you should know the difference has addressed the differences between sex and gender, a matter we have treated in previous reports (see for example, New findings, new controversy)

It starts by stating that embryos do not have a gender, but rather they have a sex. Gender refers to social and cultural differences between sexes, but not biological ones. A male or female embryo should be defined by its biological sex (by the sex chromosome pair).

According to the Oxford English Dictionary, “sex” is defined as “either of the two main categories (male or female) into which humans and many other living beings are divided on the basis of their reproductive functions”.

The World Health Organization defines “sex” as the “biological and physiological characteristics that define men and women”.  Similarly, it defines “gender” as the “socially constructed roles, behaviors and attributes that a given society considers appropriate for men and women”. Additionally, the American College of Obstetricians and Gynecologists defines “sex” as the “designation of a person at birth as male or female based on anatomy and biology“.

The American Association for Reproductive Medicine Ethics Committee uses the term “sex” when discussing the selection or determination of embryos. This document, published in 2015, replaces others previously published in 2004 and 2008.
