Although BVDV-free offspring have been produced from persistently infected bulls and heifers via advanced reproductive techniques, embryos and semen can potentially transmit the virus. Due to this potential for transmission, appropriate testing is necessary to ensure freedom of semen and embryos from BVDV. In the future, less constraining quality control measures may ensure freedom of embryos and semen from BVDV. These quality control measures require additional research to be validated.

Background: Para-phenylenediamine (PPD) is a crystalline solid that belongs to the aromatic amine group, widely used in the manufacturing of various dyes. PPD exhibits toxic effects on female hormone stability, ovarian function, and embryo development. Although studies have shown that PPD exposure can damage oocyte quality in female mice, research on its effects on male reproductive capability, particularly on human sperm quality and function, is limited.

Background: The vast majority of men with CF (mwCF) are infertile. Improvements in assisted reproductive technology (ART) have made it possible for these patients to become biological fathers.
Methods: Data were examined for all male CF patients attending a large adult CF center over a 23-year period.

Sperm vitrification is an alternative freezing method, which includes high cooling rates and non-permeable cryoprotectants agents. The first attempt in equids was using the spheres technique by directly dropping small volumes of the sperm into liquid nitrogen. Later, vitrification was developed using 0.

Pig production through crossbreeding methods is a pillar of the swine industry; however, research on the fertilization ability of male pigs in crossbreeds is lacking. Therefore, this study investigated the effects of Duroc sperm (DS) and Landrace sperm (LS) on fertility in Yorkshire × Landrace × Duroc (YLD) oocytes. Sperm were collected from the Duroc and Landrace species, and sperm characteristics, viability, and acrosome reactions were analyzed using flow cytometry.
