I've got to admit, I was initially shocked when I found out that people could order sperm from the internet to get pregnant, almost as casually as ordering your online groceries, but once I'd thought about it, I could see the benefits. Sometimes women just don't want to have their most intimate parts probed at a clinic, and if you're planning on being a single mother, maybe you don't want to have to explain your choice to the doctor. The screening process for adoption is getting ridiculous. You can't adopt if you're disabled, ill or overweight. I even know one couple who were refused adoption because they both worked and social services wanted one parent to stay at home with the child.
Having a viable and hassle free way of getting pregnant is the answer, and a lot safer than advertising privately. All the donors are screened for infectious diseases and you don't have to risk meeting up with someone who may be dangerous.
What about the child's right to a father? Well, since one in three marriages now end in divorce, with nasty custody battles and kids being pulled apart and witnessing rows, I'd say the sperm donor child has a greater chance of being happy. At least he doesn't become another statistic of divorce.
