To evaluate the effectiveness of using single step or sequential media for embryo culture. A prospective randomized study was conducted from 1st January 2019 to 31st 2021. 200 donor oocyte cycles were by computer generated list and divided into 2 groups. Group (n=100), in which used culture while group B All mature injected with morphologically normal motile sperm Intracytoplasmic injection (IC...

Recent advances in nonsurgical deep uterine (NsDU) embryo transfer (ET) technology allow the noninvasive transfer of porcine embryos into recipients, overcoming the most important impediment for commercial ET in this species. Although many factors in the porcine ET-field have been recently evaluated, many others remain to be explored. We investigated here the future reproductive performance of ...

The objective of this research was to investigate the capability donor cattle produce embryos by comparing three breeds, namely Bos taurus beef (Limousin), dairy (Friesian Holstein/FH), and indicus (Peranakan Ongole/PO). This observational method with in vivo embryo production a nonsurgical collection (flushing). data collected were then processed using one way ANOVA method. results showed that...

ABSTRACT Global advances in reproductive biotechnology have allowed for the transfer of embryos from donor females with high genetic merit to recipients using cryopreservation technique, which preserves an embryo excellent quality and viability, thereby achieving a feasible pregnancy rate. The objective this study was evaluate viability Holstein that been cryopreserved more than 40 years under ...

Embryo transfer in camels was initiated to respond to demand from the camel industry particularly in the United Arab Emirates since 1990. This paper reviews the research performed in critical areas of reproductive physiology and reproductive function evaluation that constitute a pre-requisite for a successful embryo transfer program. A description of donor and recipient management as well as a ...

Mammalian oocyte maturation and early embryo development processes are Ca(2+)-dependent. In this study, we used confocal microscopy to investigate the distribution pattern of Ca(2+) and its dynamic changes in the processes of bovine oocytes maturation, in vitro fertilization (IVF), parthenogenetic activation (PA) and somatic cell nuclear transfer (SCNT) embryo development. During the germinal v...

An assessment was made of the risk of transmission of foot and mouth disease (FMD), vesicular stomatitis, bluetongue, tuberculosis and brucellosis by llama embryos. The study suggests that embryo transfer is a safe method for the international movement of llama embryos despite the special characteristics of these embryos, such as the absence of a zona pellucida, and despite the lack of data on ...
