The law doesn't require people to get tested for STIs every time they bone someone new, because that would be impossible to mandate and also a little creepy; it's pretty much expected that consensual sex-having adults make their bed so they can lie/sleep with partners in it, etc.
But the U.S. Food and Drug administration won't permit "informal" sperm donor transactions — under federal regulations, a donor must undergo expensive tests on his blood and urine in a medical setting within a week of every transfer. This poses a problem for lesbian couples and single women who can't start a family without sperm and therefore must pay hundreds of dollars to have their pregnancy multi-managed by the government.
According to the San Francisco Chronicle, a Bay Area woman is suing the FDA for her right to get pregnant all by herself — well, without paying for a fertility clinic or sperm bank's intervention, that is. The government accountability group Cause of Action, which is arguing her case, said in a lawsuit filed last week that the current rules are "costly and burdensome" and "unconstitutional to the extent that they operate to regulate noncommercial, sexually intimate choices and activity."
"There are many women in same-sex relationships and single women who aren't able to have their own biological child as a result of these policies," Rebekah Orr, a spokeswoman for Equality California, told the Chronicle. "For any parent who has had difficulty conceiving and anyone who dreams of being a parent, that's just heartbreaking."
There are some controversial characters that could also be aided by the legislation, like infamous Sperm Donor King Trent Arsenault, who donates his spunk to women he meets online — over a dozen of his offspring are running around across the country and seven other women are currently impregnated with his seed. The FDA warned him back in December to stop giving away his sperm or face hefty fines and up to a year of prison time. (He hasn't listened.)
