Multiple Mechanisms Controlling Uterine Function: Editorial to Special Issue "Molecular Mechanisms of Uterine Receptivity for Embryo Implantation".

Uterine (endometrial) receptivity is the ability of the endometrium to successfully attach to the embryo, to promote its implantation, to nourish it and keep it alive [...

Mitochondria in Human Fertility and Infertility.

In human spermatozoa and oocytes (and their surrounding granulosa cells), mitochondria carry out important functions relating to human fertility and infertility. Sperm mitochondria are not transmitted to the future embryo, but are closely related to the generation of energy needed for sperm movement, capacitation, and acrosome reactions, as well as for sperm-oocyte fusion. On the other hand, oocyte mitochondria produce energy required for oocyte meiotic division and their abnormalities can thus cause oocyte and embryo aneuploidy.
