There are many aspects to sperm donation that hit a raw social/emotional/cultural/instinctual nerve.<p>— There is massive demand for sperm from desirable men but zero demand for undesirable men. There is only a shortage because clients are wholly uninterested in most sperm. This is a reminder of natural behaviors, but made more explicit when society used to soften the blow until now. If in the future, undesirable men have fewer and fewer occasions to reproduce, and are rejected more and more explicitly through increasingly online and impersonal services, this might probably lead to social unrest.<p>— The anxiety of not seeing your genes passed on. Even if you have an existentialist mindset, it can affect you on a fundamental level. I saw a comment on the NY Times section of a person saying their excellent genes might die with them. But isn't the possibility to reproduce the fundamental, inevitable benchmark for the worth of genes, by definition? It does invoke a strange impression that Isaac Newton not reproducing does imply a certain failure on an important criteria compared to a junkie having many children.<p>— From a Darwinian perspective, donating sperm to many different women but not having to expend any energy raising them is probably the ideal. Of course, from a cultural perspective it's frowned upon. Some of these donors are probably more genetically successful than many kings and conquerors of the past.<p>— The complex feelings successful donors experience as a result of all of this<p>— The clash of morality and Darwinian success. Most commenters on the Times noted the number of foster children awaiting care. But to me, that sounded completely tone deaf. The drive to reproduce is something so raw and fundamental that you'll have a hard time convincing people not to do it in exchange for fulfilling some vague moral appeal. Ironically, the ones who listen to this brand of morality and opt to raise another person's child will be rewarded by not passing on their genes. Conversely, adulterous people who employ to cuckoo tactic or parents who abandon their child for adoption are rewarded for it. Their personality and decision style passes on.
