  Although cryopreservation of ovarian tissue has advanced greatly, it remains a challenge, and protocols should be optimized to handle the heterogeneous nature of ovarian samples. In an effort to address this factor, the present study evaluated the effects of corpus luteum (CL) and side of ovaries (right ...  Read More

Comparison of sperm characteristics and antioxidant and oxidant levels in bull semen frozen with four widely used extenders

Kimia Maleki; Esmail Ayen; Amir Khaki; Ali Soleimanzadeh

Volume 14, Issue 7 , July 2023, , Pages 373-379

  Sperm survives for a very short time in fresh semen, and slow cooling to 5.00 ˚C kills a large number of sperms. This study was aimed to compare the semen quality parameters and anti-oxidant levels in four extenders (manual, Triladyl, Steridyl and AndroMed). Semen samples were obtained from a total ...  Read More

Cuauhtémoc Cruz-Valencia; José Antonio Herrera-Barragán; Fernando Gual-Sill; Juán José Pérez-Rivero; Zulma América Soto-Guerrero; Fernanda Rodriguez-Hernández; Juán Gabriel Rivera-Martínez

Volume 12, Issue 2 , June 2021, , Pages 137-141

  Harris hawks (Parabuteo unicinctus) are the raptors with more anthropogenic use, which makes it necessary to improve their reproduction either natural or assisted for sustainable use even though they are not endangered. The aim of this study was to determine fresh and thawed P. unicinctus sperm capacitation ...  Read More

Effects of curcumin on canine semen parameters and expression of NOX5 gene in cryopreserved spermatozoa

Parisa Aparnak; Adel Saberivand

Volume 10, Issue 3 , September 2019, , Pages 221-226

  Canine seminal plasma contains antioxidant enzymes to protect sperm against internally generated ROS. These enzymes are removed from seminal plasma during the process of cryopreservation. The freezing/thawing process can cause some morphological and functional changes via ice crystallization and osmolality ...  Read More

Effects of new synthetic cryoprotectant agents on histological characteristics of various classes of vitrified bovine pre-antral follicles

Mohammad Hamed Shahsavari; Gholamali Moghaddam; Hossein Daghigh Kia; Ana Paula Ribeiro Rodrigues

Volume 10, Issue 1 , March 2019, , Pages 9-16

  Previous studies have reported many discrepancies about the best type and concentration of cryoprotective agents (CPAs) and biological variability among various pre-antral follicle classes after cryopreservation of ovarian tissue. The aim of this study was to investigate the impacts of some synthetic ...  Read More

Influence of Added Vitamin C and Vitamin E on Frozen-Thawed Bovine Sperm Cryopreserved in Citrate and Tris-Based Extenders

Reza Asadpour; Razi Jafari; Hossein Tayefi - Nasrabad

Volume 2, Issue 1 , March 2011, , Pages 37-44

  The objective of this study was to evaluate quality of frozen-thawed bull semen processed with extenders containing vitamin C and E as antioxidants. Pooled semen's were collected from 5 bulls and diluted to a concentration of 30 × 106 sperm/mL with citrate –egg yolk (CEY) or Tris – ...  Read More
