S1E3: a male prisoner attempts to rape a female officer. She bites his ear off. S2E5: female humans are captured by Cylons and forcibly impregnated in a 'baby farm.' S2E10: rape is used in the interrogation of a female Cylon prisoner by a group of human men. Assault is off-screen but the aftermath is on-screen and references are made to the attack. The sexual assault and attempted rape of another female Cylon are also shown on-screen. [This scene was cut out in the TV editing process, but the DVD edition has it restored]. S4E17: a male character is manipulated into sex with someone who appears to be his partner but is not. His partner is tied up and forced to watch this happened as a form of torture. Incest in the series is between Cylons, not humans.
