Embryo Production in Mares by Icsi and Conventional Et After Grade Iii Perineal Rupture: a Case Report
Year: 2024
Type: article
Study design: Case Report
Abstract: This study reports the case of a high genetic merit Quarter Horse mare that suffered a Grade III perineal laceration, which was a dystocia, at her first foaling. Five surgeries were performed over a three-year period to restore anatomy and reproductive function. A follicular aspiration protocol followed by cytoplasmic sperm injection (ICSI) was then performed, resulting in five embryos that were cryopreserved by vitrification. Two embryos were transferred and one of them resulted in pregnancy and the birth of a healthy foal. The animal was then subjected to a conventional embryo collection program in which a viable embryo was collected and transferred. Pregnancy was confirmed by ultrasound and the foal was born in July 2023. It can be concluded that the ability to produce offspring was restored in this mare, using the ICSI and TE biotechniques.
