Use of Progesterone-releasing Intravaginal Device to Prepare Embryo-Recipient Mares

Synchronization between donor and recipient mares is an essential factor for pregnancy establishment in embryo transfer (ET) protocols. Several protocols using long acting progesterone (P4LA) have been used for the synchronization of recipient mares. However, these protocols do not allow reuse these mares in a short time after P4LA application. In this context, the efficiency of progesterone-releasing intravaginal device (DP4) on increase plasma progesterone (P4) levels and the quickly decrease on P4 levels after DP4 removal, showed an interesting results to use this to prepare equine recipients.
