The term “cryopreservation” refers to the process of cooling cells and tissues and storing
them at subzero temperatures in order to stop all biological activity and preserve their …

Objective Amino acids can protect sperm structure in cryopreservation due to their
antioxidant properties. Therefore, the present study aimed to investigate the protective effect …

Cryopreserved gametes and embryos are a major feature of human-assisted reproduction
and patient care services, accounting for an increasing number of births worldwide. Since …

Assuming the adverse effects of reactive oxygen species (ROS) on sperm function, this study
was conducted to assess the effects of cysteine and glutamine as effective antioxidants on …

The present study evaluated the effect of the addition of antioxidants anethole (AN) and
robinin (RO) in the vitrification solution, and the in vitro incubation (IVI) medium of ovine …
