I am 32 and have had 2 successful pregnancies but had my tubes tied.  My new husband and I are undergoing IVF right now his sperm count is great and they did the first two ultra sounds where done to make sure things where looking good.  Do you think chances are high that I will get pregnant on my first IVF try?
Given that your partners' sperm count is good, and you have no other medical issues other than your tubes being tied I think your chances of pregnancy are fairly good. Having said that you should remember human reproduction is quite inefficient .....most of the IVF clinics quote a success rate of 30%. Let me know if you have any other queries. Thanks
