The oviduct or Fallopian tube is the anatomical region where every new life begins in
mammalian species. After a long journey, the spermatozoa meet the oocyte in the specific …

BACKGROUND Reproductive tract infection is an important factor leading to male and
female infertility. Among female infertility factors, microbial and viral infections are the main …

To fuse with oocytes, spermatozoa of eutherian mammals must pass through extracellular
coats, the cumulus cell layer, and the zona pellucida (ZP). It is generally believed that the …

Oocytes of all mammals contain an endogenous lipid reserve. This feature reflects their
shared ancestral origin, the yolk-rich amniote egg. However, the lipid is species-specific in …

Members of the lymphocyte antigen-6 (Ly6)/urokinase-type plasminogen activator receptor
(uPAR) superfamily of proteins are cysteine-rich proteins characterized by a distinct disulfide …

Male fertility problems range from diminished production of sperm, or oligozoospermia, to
nonmeasurable levels of sperm in semen, or azoospermia, which is diagnosed in nearly 2 …

Formation of spermatozoa of normal shape, number, and motility is insufficient for the male
siring of pups. The spermatozoa must be accompanied by sound fertilizing ability. We found …

MicroRNAs (miRNAs) are small endogenous molecules that are involved in a diverse of
cellular process. However, little is known about their abundance in bovine oocytes and their …

Seminal plasma is a promising biological fluid to use for noninvasive clinical diagnostics of
male reproductive system disorders. To verify a list of prospective male infertility biomarkers …

Infertility affects a significant proportion of the reproductive‐aged population, with male‐
associated factors contributing to over half of the cases. However, current diagnostic tools …
