Several: Age of female most important, ovarian reserve tests (fsh, amh, afc), stimulation factors, excess embryos for freezing, number and quality of embryos, day of transfer, chromosome screening, technique of transfer, and ejaculated vs testicular sperm.

Your info says you are 29 and in the UK? I do not know the UK standard of care but the science is the same. Best wishes! ...Read more
Success rate of IVF with needle aspiration vs tissue extraction of sperm....any difference in outcome?
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%. ...Read more
Many ways: 1. Majority: ejaculation in sterile cup (fresh or frozen-thawed). 2. Per-cutaneous sperm aspiration with a needle 3. Microsurgery of the testes ducts if there is an obstruction 4. Surgery in one or both testes to harvest sperm from the testes. The choice is dependent on initial sperm analysis and male evaluation prior to ivf. ...Read moreSee 1 more doctor answer
Frozen sperm. Fresh eggs. Both proven donors. Nulligravid 42 yo woman. Odds of conception after et with 3?
Very good: The odds are excellent as long as all other aspects of your workup have been negative. Pregnancy rate with 2 embryos can give a 70% chance. Replacing 3 embryos in this situation would not be suggested as long as the egg donor was 21-28. Most donors are not accepted over 30. The risk of triplets is quite high and would cause significant obstetrical issues such as prematurity, decreased fetal size.. ...Read moreSee 2 more doctor answers
