Democrat Constance Johnson added a paragraph to the bill that states that masturbation and other sex acts should be considered as lethal to an unborn baby as abortion.
The amendment to the bill read: "[A]ny action in which a man ejaculates or otherwise deposits semen anywhere but in a woman's vagina shall be interpreted and construed as an action against an unborn child."
However, Johnson later withdrew the amendment, revealing that the addition was an ironic statement on the law's focus on the woman's role in the reproductive process.
She told The Guardian that her amendment "represents the culmination of my and many other Oklahomans' frustration regarding the ridiculousness of our reproductive policy initiatives in Oklahoma.
"The Personhood bill would potentially allow governmental intrusion into families' personal lives by policing what happens to a woman's eggs without any similar thought to what happens to a man's sperm. My amendment seeks to draw attention to the absurdity, duplicity and lack of balance inherent in the policies of this state in regard to women."
Senator Johnson added: "This amendment seeks to draw humorous attention to the hypocrisy and inconsistency of this proposal - from the Republican perspective of down-sized government and less government intrusion into people's private affairs."
The recently passed 'Personhood' bill in Oklahoma states that human life starts at the moment of conception.
The bill reads: "The unborn child at every stage of development (has) all the rights, privileges, and immunities available to other persons, citizens, and residents of this state."
