Likelihood of pregnancy after the transfer of embryos derived from follicle aspiration and in vitro embryo production sessions with different relative efficiencies
LF Feres, LGB Siqueira, MP Palhao… - Animal reproduction …, 2018 - Elsevier
The aim of the present study was to evaluate the likelihood of pregnancy of in vitro-produced
(IVP) embryos from batches with distinct relative efficiencies. Data were retrospectively
analyzed from 605 transvaginal ultrasonic-guided follicle aspiration sessions (OPU)
followed by in vitro embryo production (IVEP) and 2456 fresh embryo transfers (ET),
performed between 2008 and 2012 in individuals of the Gir (dairy Bos indicus) breed. The
OPU and IVEP were performed using standard procedures by a single group of technicians …
