This drains some of the mystery out of getting pregnant and also introduces a dangerous element of expectation. If sperm is like a toaster, then customers may expect their money back or a trade-in if a baby doesn't live up to billing. Banks have been sued by parents of kids who suffer from debilitating illnesses. Virtually no rules govern sperm banking. The Food and Drug Administration has repeatedly planned and then failed to issue sperm-bank regs.
Individual states regulate but very halfheartedly.
The chaos of sperm banking means it answers largely to the whims of desperate customers and not to high medical or ethical standards. Fewer than a dozen of the several hundred sperm banks in the United States have bothered to meet the accreditation standards of the American Association of Tissue Banks. Some sperm banks keep elaborate records. Some seem to keep none. No sperm bank trade association exists, so no one even knows how many banks there are.
