The 40-second video opens with a smiling, cooing baby with the lullaby 'Go to sleep' playing in the background.
Text later appears stating: "She deserves to be loved. She deserves to be wanted. She deserves to be a choice."
Viewers are urged at the end of the advert to "stand with Planned Parenthood" before a logo of the Agenda Project Action Fund appears.
Planned Parenthood is a non proft organisation in America who provide health services, including abortions.
Laura Ricketts from the pro-life Christian group 'And Then There Were None' told CBN News the advert has backfired.
She explained: "The pro-abortion lobby needs to reinforce the fact that a baby isn't a baby unless you decided the baby is a baby.
"Abortion can't survive if the general public accepts the fact that humanity begins at conception.
"And so the subtle very insidious message of this advertisement is that 'you don't get the cute and the cuddly unless you want it - it's not there really' and that's a very dangerous message to be spreading.
"On the surface, those of us who are pro-life are appalled, but you see, when you work in the abortion industry, or a woman who receives an abortion, it's very hard to admit to yourself what you already know and what you already know is that is a child."
Comments under the video posted online both questioned the authenticity of the advert and the message it sent.
One user commented: "I can't tell if this is a real ad or one made by pro-life people to stir the pot. If it is real it's by far one of the worst advertisement decisions I've seen in my life."
Another said: "Thank you Planned Parenthood for developing one of the best pro-life ads I've seen in a while. This ad encapsulates the absurdity of the pro-choice position!"
Many Christians also commented.
Another comment read: "If anyone causes one of these little ones--those who believe in me--to stumble, it would be better for them to have a large millstone hung around their neck and to be drowned in the depths of the sea. Matthew 18:6."
It is unclear if the video was in fact created by the Agenda Project Action Fund, which is a non-profit political organisation which has been endorsed by US Senator Bernie Sanders.
