16 th International Congress on Animal Reproduction, July 14-17, 2008

INTRODUCTION: In vitro fertilization allows oocytes to be fertilized in l aboratory conditions with valuable sperm, and can resolve fertility problems. The sperm of valuable males can be cryo-banked. The aim of our study was to increase the fertilization ability of frozen rabbit semen.

CONCLUSION: We determined that the frozen-thawed rabbit semen can fertilize, but penetrates the zona pellucida with lower rates. We report for the first time that application of laser zona drilling in rabbits can increase significantly in vitro fertilization with frozen-thawed rabbit semen.

"Recipient eggs were collected and held in vitro in Chinook salmon ovarian fluid until micromanipulation was completed. While keeping the chorion intact, the fluorescence DNA stained metaphase plate of the egg was ablated using a laser XYClone module [Hamilton Thorne Biosciences, Inc.]. The donor nucleus was then transferred through a micropyle, the natural sperm entry site in the chorion."

Utilization of Laser Assisted Hatching to Improve the Pregnancy Rate of In Vitro Fertilized Bovine Embryos (Download Poster)

"These results demonstrate that laser assisted hatching using the XYClone system does not inhibit in vitro embryo viability and development. A significant difference was found in the 60 day pregnancy rate between control and cut embryos. This difference exhibits a large potential for this system to improve 60 day pregnancy rates of in-vitro produced embryos."

SUMMARY (EXCERPT)

Vitrified large equine embryos >800 µm recovered on Day 8 after ovulation have not been successfully transferred yet. In this study, we examined the effects of reduction of the blastocoelic fluid and microinfusion of a cryopreservative prior to vitrification on pregnancy outcome.

To facilitate aspiration and microinfusion, a laser system (XYclone; Hamilton Thorne, Beverly, MA, USA) was applied. Approximately 20% of the total blastocoelic fluid was removed using a standard micromanipulator and microcapillary system (Eppendorf). All embryos were then vitrified as previously described (Eldridge-Panuska et al. 2005 Theriogenology 63, 1308-1319).

None of the control embryos nor the split embryo in the treatment group led to the formation of an embryonic vesicle. However, the blastocyst, which had undergone both aspiration of blastocoelic fluid and microinfusion of VS1 (#5), had formed an embryonic vesicle at Day 15 after ovulation. During a further exam on Day 28, the uterine tone in the recipient was still increased, but ultrasonography revealed resorption of the embryo, which was probably caused by heat stress. Nevertheless, we will test this protocol for the cryopreservation of large equine embryos on a larger scale during the next breeding season.

Laser zona drilling does not induce hsp70i transcription in blastomeres of eight-cell mouse embryos. Cristina Hartshorn, Ph.D., Aleksandra Anshelevich, B.S.,
Lawrence J. Wangh, Ph.D.

To assess whether zona drilling with a 1,480-nm laser induces heat shock in eight-cell embryos, we measured hsp70i RNA levels in sets of single blastomeres isolated after laser treatment of mouse embryos that had or had not been heated at 43°C. Unlike heating, laser zona drilling did not stimulate hsp70i expression, even in the blastomeres closest to the laser beam, corroborating the safety of this procedure for assisted reproduction.
