Embryo transfer technique: Factors affecting the viability of the corpus luteum in llamas

In vitro Embryo Production in Llamas (Lama glama) from In vivo Matured Oocytes with Raw Semen Processed with Androcoll‐E using Defined Embryo Culture Media

“…One day after donor surgery, recipients with a dominant follicle received a single IV dose of 8 μg of buserelin to induce ovulation and 2 days later ovulation was confirmed by transrectal ultrasonography. Transcervical ET was carried out on day 6 after buserelin administration (Trasorras et al. 2010).…”

Early Embryonic Development and Maternal Recognition of Pregnancy in Camelids: A Review

“…In llamas, transfer of embryos to the uterine horn ipsilateral to the ovulation side resulted in higher pregnancy rates for left ovulation (50%) than right ovulation (30%) recipients, while transfer of the embryo to the left uterine horn when the ovulation (mature CL) was on the right ovary resulted in only 20% pregnancy rate (Trasorras et al, 2010). In alpacas, transfer of embryos collected at 7 days and 4 hours into the left horn, regardless of the side of ovulation in the recipient, resulted in higher pregnancy rate (20.3%) when the CL was on the left ovary than when the CL was on the right ovary (12.4%) (Picha et al, 2010).…”

Embryo Transfer

“…Soft latex gloves and generous the left uterine horn, independent of the position of the corpus luteum (left or right). 23 These authors proposed that the most desir able option to improve the pregnancy rate is to select recipi ents with leftside ovulation and to transfer the embryos to the left uterine horn. 22 In, alpacas, Sumar et al (2008) reported a higher preg nancy rate when embryos were placed in the left uterine horn and the corpus luteum was on the left ovary (35.2%) com pared with transfer into the left uterine horn with the corpus luteum on the right ovary (29.3%).…”
