Summary: collection by transcervical route. Thus, hormonal protocols aiming at the relaxation of the cervix become important for the development of this technique. However, the hormonal environment of embryo donors needs to be compatible with embryo formation, and little is known about the effect of hormones used in the cervix dilatation protocols on progesterone (P4) concentration, as well as on embryo development and quality (EQ). Thus, this study aimed to evaluate the influence of a hormonal protocol of cervical dilatation, on the P4 serum concentration, stages of development and EQ. Thus, we can conclude that cervical dilation hormonal protocol promotes a drop in P4 concentrations after 6 h of administration, although it does not affect the development of ovine embryos.
