The zona pellucida (ZP) is an extracellular matrix universally surrounding mammalian eggs,
which is essential for oogenesis, fertilization, and pre-implantation embryo development …

The zona pellucida (ZP) plays vital roles in reproductive processes including oogenesis,
fertilization, and preimplantation development. Both human and rat ZP consist of four …

Background: Empty follicle syndrome (EFS) is defined as the complete failure to retrieve
oocytes after ovarian stimulation. Although several mutations in ZP1, ZP2, ZP3, and LHCGR …

Empty follicle syndrome (EFS) is a rare condition in female infertility. It is characterized by
the inability to retrieve oocytes from visibly large, normally developing follicles in the ovaries …

The morphology and quality of oocytes is set during oo-and folliculo-genesis, and is
completed during final maturation. Early embryonic development is associated with the …

Defective oocyte maturation is a common cause of female infertility. The loss of the zona
pellucida (ZP) represents a specific condition of impaired oocyte maturation. The …

Zona pellucida (ZP) proteins are important for fertilization and sperm binding and are closely
associated with cumulus cells. Communication between cumulus and oocytes is facilitated …

Recent advances in our understanding of fertilization are summarized, highlighting newly
discovered molecules implicated in sperm interactions with the epithelia of the female …

RNA interference, a recently discovered new mechanism controlling gene expression via
small RNAs, was shown to be involved in characterization and control of basic ovarian cell …
