Hmm, I think this topic is about as controversial as the topic of abortion. First, I'd like to say very nice post and topic. Next, I'd like to say that according to Islamic laws, I do not think it would be a good idea for Muslim men to donate sperm UNLESS it was to their own wife. Now, donating to a sperm center for mass distribution to whomever, doesn't sit well for me as I do not want another child with my likeness strolling around in another part of the world. I only want MY own child be the ONLY one with MY likeness. Granted, I know the benefits this would give to the mother who is infertile, but I believe that the way we are going technology-wise; we'll be able to help infertile women become fertile in the very near future. I am only saying this on my behalf and according to the Islamic Law; I am sure other guys have a different approach.
