That ad campaign also highlights some ideological reasons I would be against donating sperm, namely I don't think I could specify whom would be able to get access to it once I donate. For couples, no matter the sexuality of those involved I think it would be cool, but I am conflicted in the availability of such highly selective sperm to single women whom are not required to submit to, cooperate with, or care for the man that has it.
I don't think society at large benefits by allowing women to artificially narrow the genetic pool in such an immediately non consequential way, especially concerning the Australian push to get 'healthy, intelligent, and generous' gay men to donate more; it implies an inherent lack of these qualities amongst straight men, it also further downplays the role of a father in a home, reducing us to mere gene donation, and negatively affecting the outcomes of more and more children.
