There are 3 types of DE cycles at Cooper.
The cheapest is "shared" where you get matched up with a woman who needs IVF. You pay for her IVF and you get half of her eggs.
The next one is the "split" cycle, were you and another woman needing eggs get matched with 1 donor and you two split her eggs.
Last is a full DE cycle.
Those prices posted do not include the $400 application fee and the monitoring package of $1280 for 16 services of BW/US. They do offer 1/2 packages (8 services) for $640.
So for the full cycle of $18720, you need to add $400, $1280 plus meds of roughly $4000.
