Article Synopsis
- This study investigated the effects of curcumin and zinc compounds on the quality of ram sperm after thawing following cryopreservation.
- Various concentrations of curcumin, zinc chloride, zinc oxide nanoparticles, and Curc-loaded zinc oxide nanoparticles were tested using a Tris-base extender on ram semen samples.
- Results indicated that 1 µg/mL of Curc-co-ZnO-NPs significantly improved sperm viability, motility, and integrity, while reducing malondialdehyde levels and abnormalities after thawing.
Background: In reproductive biotechnology, sperm cryopreservation has a vital role to play. Cryopreservation of sperm produces reactive oxygen species (ROS), which disrupt sperm function and structural competence. Numerous protective chemicals, including fructans, have been used during sperm cryopreservation.

Objective: To determine the protective effects of different concentrations of laminarin on ram sperm motility, viability, abnormalities, membrane, and DNA integrity, superoxide dismutase enzyme (SOD) activity, and malondialdehyde (MDA) production after freeze-thawing.
Materials And Methods: The ejaculates of four rams were collected and stored at 35 degree C.
During the cryopreservation of sperm, the production of highly reactive oxygen species (ROS) can reduce their viability and fertility. However, the addition of antioxidants can help reduce the harmful effects of ROS. One such antioxidant is selenium, which is a co-factor of the glutathione peroxidase enzyme that is effective in scavenging ROS.

Objective: This study aimed to evaluate the effects of cryopreservation on ram semen after adding magnetic nanoparticles (MNPs) to separate X and Y chromosome-bearing spermatozoa.
Methods: The experimental ram sperms in this research included treated spermatozoa (50 μg/ml MNPs) and non-treated spermatozoa.
