Conteúdo: 	Abstract: Non-surgical embryo recovery (NSER) is usually preceded by a cervical relaxation in ovine donors, based on estradiol benzoate (EB), prostaglandin (PGF), and oxytocin (OT). However, it is hypothesized that, due to poorly understood mechanisms, EB can result in embryotoxic actions. To evaluate this, 20 min before NSER superovulated sheep were induced to cervical relaxation with 0.0 (G0.0), 0.5 (G0.5), or 1.0 mg (G1.0) of EB associated with 37.5 μg of PGF 16 h before NSER and 50 IU of OT. In doing so, the efficiency and duration of the NSER procedure showed no compromise (P > 0.05). Additionally, the presence of EB did not affect (P > 0.05) the embryo's morphological quality, the development dynamics, or the abundance of transcripts associated with embryonic quality (OCT4 and NANOG), cellular stress (HSP90 and PRDX1), and apoptosis (BCL2 and BAX). A similar result (P > 0.05) was also observed when comparing embryonic cryosurvival at 24 (52.0, 52.0, and 54.0) and 48 h (60.0, 54.0, and 58.0) of in vitro culture (G0.0, G0.5, and G1.0, respectively). Thus, we can conclude that EB use does not compromise embryonic quality and cryoresistance.
