When a couple is ready to have children but there is an infertility issue with the father-to-be that prevents normal conception, in this day and age they have a number of options to consider. Artificial insemination from an anonymous donor is one route to take, as is as adoption. Or here’s another approach–if you’re the mother, how about getting pregnant through in vitro fertilization with a sperm donation from your husband’s father?
For this article, we’ll be taking a slightly more serious tone than usual as we explore that very issue and the current controversy surrounding it. It’s become the topic of intense debate in Japan over the past few days after new details about the practice emerged from a maternity clinic in Nagano Prefecture. Join us as we introduce the facts and examine some of the ethics involved through reader opinions.
