Personally I've always thought orcs just display limited sexual dimorphism. When Morgoth created the first orcs he was attempting to create a warrior race, one that could serve as an expendable army that he could utilize against his foes. Traits that differentiated the sexes would have been largely unnecessary, with only the base necessities for reproduction being retained.

Also to remove females from the active fighting forces would represent a considerable lose of numbers on the field, even if the majority of orcs were male. Instead I propose that female orcs fought alongside their male counter parts all along, but given their limited sexual dimorphism their would be no way to realize this or identify which was which short of examining their genitalia.
