Hearts ivf

My name is Katelyn, my Husband and I have been trying to conceive for almost 3 years now. My dr has put me on fertility meds and when they were not working and when we were not conceiving, we got my husbands sperm tested. We learned he has a low sperm count and the sperm he does have, is not viable. My doctor has told us that ivf or iui is going to be our best option. We have a 2 soon to be 3 year old and we want our family to be complete. We love our daughter but we still want a few more children. Anything helps, thank you
