This cour­se fo­cu­ses on the des­crip­tion of the basic con­cepts of mo­le­cu­lar sex, genes in­vol­ved in sex de­ter­mi­na­tion, and hor­mo­nes in­vol­ved in se­xual dif­fe­ren­tia­tion. 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.
