 A male nurse complained about an advert for an all-female obstetrics and gynaecology practice in Columbia, Maryland claiming this was a form of sexual discrimination.Dr David Garfinkel, a New Jersey-based ob-gyn sued his former employer after being fired due to, as he claimed, "because I was male, I wasn't drawing as many patients as they'd expected".So far, all legal challenges by male gynaecologists to remove patient choice have failed due to there being protection in law for 'bona fide occupational qualification' which in previous cases involving wash-room attendants and male nurses have recognized justification for gender-based requirements for certain jobs.
