My husband is older than me and the chances of reversal of his vasectomy, we were told, were not good. Plus, we have no where near the financial funds to go and explore that option anyways. All I want to do is get pregnant. I am 24, healthy weight, healthy BMI, healthy everything. Is the only way for this to happen for me to go out and spend hundreds on a vial of sperm. If so, I have no clue as to what the differences are. Which one do I need to buy. I see a lot about IVF IUI ICI, which one relates to my situation? Is this something that I can do on my own or do I have to have a doctor do it, is this something I can do in the privacy of my own home? Help please. All I want is a family and it seems out of reach.
