Here are some ...: IVF is done in 2 ways: 1. Mix 1-4 timely retrieved eggs with the sperms from partner/donnor in lab so to form a fertilized eggs/embryos, then transport the embryos to uterus; 2. Inject a retrieved sperm (aspirated and selected) into a retrieved egg to form a embryo for IVF. Success rate: 1. method 1 is about 22-25% per cycle & 25-35% for multiple cycles; 2. method 2 is about 65%.
