There are many advantages and disadvantages to choosing the right method of embryo production for your cattle as both technologies have their place.

A few highlights of performing OPU on your donors can save both time and money. OPU does not utilise any hormone injections, thus minimising cost, and can be replicated as regularly as every 4 days. Whereas MOET requires bringing donors into the yards twice per day, for 3 or 4 days in a row which can be quite laborious, especially in a centre managing several programs over consecutive days.

Furthermore, OPU-IVF allows for excellent semen economy. The same straw of semen can often be used over hundreds of oocytes from multiple donors. Another advantage is that if there are large numbers of oocytes collected, they can also be split and fertilised by more than one bull in vitro.
