Introduction

Synchronization of Recipients with the Donor

  • GOAL: To synchronize the donor and recipient to be in the same stage of the oestrous cycle.
  • REASON: To prepare the uterus of the recipient to support preattachment embryogenesis.
  • HOW: Treat recipient with a hormonal regime that induces oestrus to occur at the same time as the donor.

Superovulation of the Donor

  • GOAL: To hyperstimulate ovaries with gonadotrophins.
  • REASON: To provide higher than normal numbers of follicles that reach dominance and ovulate.
  • HOW: Inject donor with gonadotrophins to hyperstimulate follicular development. Generally FSH or one of its analogs is used.
