Sexual reproduction requires the fusion of sperm cell and oocyte during fertilization to
produce the diploid zygote. In mammals complex changes in the plasma membrane of the …

Mammalian fertilization comprises sperm migration through the female reproductive tract,
biochemical and morphological changes to sperm, and sperm-egg interaction in the oviduct …

BACKGROUND The complexity of fertilization failure during assisted reproductive
technologies (ART) is often under-appreciated, as this failure can occur at any number of …

Fertilization is defined as the process of union of two gametes, eggs and sperm. When
mammalian eggs and sperm come into contact in the female oviduct, a series of steps is set …

Background Identification of single nucleotide polymorphisms (SNPs) for specific genes
involved in reproduction might improve reliability of genomic estimates for these low …

Frozen–thawed oocytes have a reduced rate of fertilization (48· 8%) when compared with
unfrozen controls (97%). In this study we have used zona-drilling to bypass the zona …

All vertebrates have an egg shell that surrounds ovulated eggs and plays critical roles in
gamete recognition. This extracellular matrix is known as the zona pellucida in eutherian …

DESPITE its importance, the molecular basis of mammalian gamete recognition has
remained unclear. The enzyme β-1, 4-galactosyltransferase (Gal-transferase) has been …

Successful fertilization heralds the onset of development and requires both gamete
recognition and a definitive block to polyspermy. Sperm initially bind and penetrate the …

Fertilization is the process by which haploid gametes, sperm and egg, unite to produce a
genetically distinct individual. Interest in this area has exploded in recent years. Here are …
