It's probably because I'm in a relationship with a partner who does have great eggs, but my RE doesn't even recommend we try IVF with my eggs because my AMH and AFC are so low. Perhaps the RE was trying to save us $ because there really aren't likely to be enough follicles to even stimulate for me... but it wasn't even one of the options on the table for us.
That said, she did suggest using my partner as an egg donor for me, and doing PGD as our first line IVF because my partner has a strong family hx of invasive breast cancer.... But if you don't have a known genetic condition, I'm not sure I would spend the extra $, time and effort...
