Double Ovidrel! dosage and low BMI

Dear Dr. Sher,

I am 43 years old, and due to the high rate of aneuploidy in the previous two attempts, and following your teachings, I convinced my doctor not to use Decapeptyl in the dual trigger, but only Ovidrel 250. However, I couldn't convince him to use a double dosage of Ovidrel... I weigh 99 lbs and am 5’6” tall (low BMI), and I had about 20 oocytes last time. Do I really need the double dosage? How can I convince him?

Thank you so much for your kindness in responding to all of us.
Anne
