This study was undertaken to compare the efficiency of fresh and frozen-thawed buck semen on in vitro fertilization (IVF) of goat oocytes. Cumulus oocytes complexes (COCs) were collected by aspiration of 2-6 mm diameter follicles, which were obtained from slaughterhouse. Upon grading, only normal quality COCs were maturated in TCM-199 for 48 hours. The percentage of COCs reached to the M-II sta...

The integrity of sperm progesterone (P4) receptor(s) and its response to steroid stimulation might be crucial for the maintenance of sperm fertilizing ability after cryopreservation. The aim of the current investigation was to study the effect of cryo-procedures on canine sperm P4 receptor(s). In addition, alteration of P4 receptor(s) at the molecular level and their functional integrity follow...

OBJECTIVE To identify the relative abundance of proteins in pooled reactive oxygen species (ROS)-positive (ROS+) and ROS-negative (ROS-) semen samples with the use of two-dimensional differential in-gel electrophoresis (2D-DIGE). DESIGN Spermatozoa suspensions from ROS+ and ROS- groups by 2D-DIGE analysis. SETTING Tertiary hospital. PATIENT(S) 20 donors and 32 infertile men. INTERVENTIO...

Introduction: Cryopreservation of semen is routinely used in a variety of circumstances including before assisted reproduction treatments, pre- radiation or chemotherapy treatment and etc. The aim of this study was to compare the effect of Butylated hydroxytoluene (BHT) and Glutathione supplemented cryopreservation medium on sperm parameters and amount of DNA fragmentation during the freeze-tha...
