These definitions make it possible to describe a set of pathologies related to genetic or hormonal alterations that will give rise to potential patients of an assisted reproduction unit. We must understand the clinical expression, therapeutic alternatives and sexual alterations with a precise and concrete definition.

We will study the molecular foundations of sex selection and we will delve into technical procedures, advantages and introduction of sexing in bovines and threatened species. We will evaluate the clinical outcomes in humans and the clinical indications. We will learn alternative methods of sex selection and deeply analyze alterations in the sex ratio for biological, environmental or cultural reasons.
