@muff,
Same here I'm my hubby got low morphology issues too. My last cycle I'm using puregon (max dosage) and menopur for my last cycle. Though I retrieved less eggs but the quality is so much better than my first cycle. Managed to transfer one grade 4 & one grade 3 day 2 embies and freezed 2 the last round.
My next cycle more or less will follow the protocol the last round, I'm worried my egg quality will drop even more due to age. So hopefully i can get bfp again this round which is the last cycle I'm trying.
All the best for your BT tomorrow & hope everything turns out fine for you! Jia you!
