Effect of Fresh and Frozen Semen on in vitro Fertilization and Subsequent Development of Goat Embryos
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...
متن کاملImpact of in vitro fertilization by fresh and frozen semen on developmental competence and cryotolerance of buffalo embryos
Production of high quality embryos in vitro needs an efficient in vitro fertilization (IVF). Seminal origin is one of the important factors that affects the success of in vitro embryo production. So our goal was to determine the effect of using fresh and frozen semen in fertilization on developmental competence and cryo-survival of buffalo embryos. Buffalo oocytes wer...
متن کاملPCR Assay for Detection of Neospora Caninum in Fresh and Frozen Semen Specimens of Iranian Bulls
Neosporosis is caused by the protozoan parasite, Neospora caninum which is major cause of fatal disease and abortion in cattle in Iran and in many countries. The economic impacts of neosporosis are lost milk, meat and abortions in cattle. The purpose of the present study was to evaluate the presence of N. caninum DNA in fresh and frozen semen samples of Iranian bulls that were used for artifici...
متن کاملIn vitro sperm penetration through the zona pellucida of immature and in vitro matured oocytes using fresh, chilled and frozen canine semen.
The aim of this study was to evaluate the effect of sperm cryopreservation and the maturation state of the oocyte on the time course of canine gamete interaction during co-culture for periods of 1-10 h. Semen samples were obtained by digital stimulation and ejaculates processed as fresh, chilled and frozen samples. Sperm were co-cultured with immature or in vitro mature bitch oocytes for up to ...
