L.E.G.I.O.N. '91 No. 28 page 12

In her fevered state, Stealth recalls her brutal mating with Vril Dox.
Stealth was born on the planet Gryx and was identified as a mutant at birth.
As such she was shunned and kept in seclusion and not taught the ways of her people.
She was also not given a name by her people. Stealth was the name her L.E.G.I.O.N. teammates gave to her.
The Gryxians were a matriarchal society which viewed the only purpose of the male was for procreation. Somewhat like the 'Pon Farr' of Star Trek, an impassioned female Gryxian is ruled by her hormones and will mate with the selected male even without his consent.
Stealth was never taught about this and when she reached that state she left Vril Dox near death after the act. (Vril was revived by cloning and transferring his mind to the clone)
The female Gryxians assume the form of the male but will revert to their natural state during childbirth.
Stealth was also never taught the ways of childbirth but instinctively knew that she had to go to a secluded world to give birth.
