What actually hurted me the more was that the wife was so desperate to be pregnant, she half-confessed that she would have leaved her husband if he didn't complied to let her ex inseminate her. What I find really enraging about it was that in the back of my head, I have the thought of the hundreds of thousands of children living either in orphanage or alone in the streets that hoped to have a family of their own. This reminded me that those people could have at least tried adoption instead of doing so many contrived inseminations, artificials or "naturals".
For me, if your partner is willing to ditch you because you are sterile, quit as soon as you can! This person isn't worth it!
