Dr. P,
Do you consider a 33% a low ICSI fertilization rate?...My DH is 34, me 33, and we never had problems conceiving before. Is this an egg or sperm issue?...
Thank you in advance for your response.

33% is low. If 10 eggs are injected at our center we expect 8 to fertilize; averages reported over a large number of clinics would predict 7 fertilized. It is not possible to know whether it is a sperm issue, egg issue or lab issue without seeing the stim sheet and lab report.
