In the name of preventing the accidental transmission of HIV, the FDA is recommending sperm banks should screen out gay donors. Gay rights groups are challenging the rule as bigoted and not based on science; they point out that HIV is increasingly transmitted via het sex, and that the HIV screening already in place is sufficient to keep the bank "accounts" safe.
Meanwhile, this could be both hard to swallow for the sperm banks, and a major blow for a core group of donors. The FDA defines "gay" as having engaged in homosexual activity in the preceding five years. If that includes either "fraternity initiation rites" or "that time at summer camp," tens of thousands of college students are gonna have to earn beer money somewhere else.
