This manuscript discussed current status of embryo transfer technologies in Japan and the world. The conception rates of embryo transfer both in fresh and frozen embryos were stable last two decades in Japan. Therefore, embryo transfer in Japan is...
متن کاملTimed embryo transfer programs for management of donor and recipient cattle.
Currently, timed ovulation induction and fixed-time artificial insemination (FTAI) in superstimulated donors and synchronization protocols for fixed-time embryo transfer (FTET) in recipients can be performed using GnRH or estradiol plus progesterone/progestin (P4)-releasing devices and prostaglandin F(2α) (PGF2α). The control of follicular wave emergence and ovulation at predetermined times, wi...
