Abstract

Effect of storage for 24 h at 18°C on sperm quality and a comparison of two assays for sperm membrane lipid peroxidation

Boars having normal (71.1 ± 1.2%; n = 10) or low (35.12 ± 3.9%; n = 10) sperm motility 24 h after collection were used, and semen was evaluated following storage in Beltsville Thawing Solution (BTS) for 24 h at 18°C. Sperm lipids were extracted and lipid peroxidation quantified.

Abstract

Hyaluronic acid in the female reproductive tract of the pig

Early embryo development requires a dynamic and active uterine environment tailored to the requirements of each embryonic stage. The development of asynchrony between the embryo and uterine environment during embryo transfer has been directly linked with both embryonic loss and abnormal development. Hyaluronic Acid (HA), has been implicated as an important factor in porcine embryo development in vitro, but little data exists on the concentrations of this glycoaminoglycan in the porcine female reproductive tract and its potential application in embryo transfer procedures.
