For a plus charity, you could donate sperm. I've heard that the price for sperm is far below the market clearing price. I'm not sure what would cause that. According to Wikipedia, if you freeze your sperm yourself and sell it on the internet, you can make a lot more, which suggests that that's true. There's also places where you're not allowed to make money or the pay is strictly limited.

If the price really is below the market clearing price, then the market is limited by the number of donors, so donating enough sperm to have a child results in one more child being born. You're not just causing one fewer person to donate sperm, or that much more sperm to be wasted, or something like that.
