It has not been documented.

Although this does NOT mean it cannot happen..


1 thing to take into consideration is that most oscars are very hard to sex. some say its impossible without venting, I am incline to agree.

Don't expect your oscar or any other common freshwater aquarium fish to change sexes on you...
