A method for obtaining at least two calves of the same sex in one calving comprises the isolation of spermia and mature oocytes of cows and the fertilization in their own separate isolated limited space. The fertilized eggs are inserted into the horns of uterus as a set of at least two fertilized eggs. Prior to fertilization, spermia are separated into those carrying X or Y chromosome according to their physico-chemical properties. The separated spermia are used for fertilization (spermia with X chromosomes for obtaining female calves and spermia with Y chromosome for obtaining male calves).
