Abortion giant Planned Parenthood reportedly issued a stealth-edit of its fact sheet on fetal development to alter language appearing to support the idea that fetuses indeed have a heartbeat after six weeks in the womb, according to Fox News.

Though it’s difficult to pinpoint exactly when Planned Parenthood edited the language, the organization’s website said that babies have a heartbeat at six weeks as early as July 25 of this year.

“A very basic beating heart and circulatory system develop,” the original fact-sheet said in its “what happens during week 5-6” section.

The edited section now says the following: “A part of the embryo starts to show cardiac activity. It sounds like a heartbeat on an ultrasound, but it’s not a fully-formed heart — it’s the earliest stage of the heart developing.”

Planned Parenthood’s new fact sheet appears to conflict with the National Library of Medicine, which says that five-week-old fetuses have a “brain, spinal cord, and heart” that begins to develop, which then “beats at a regular rhythm” around six weeks. “This can be seen by vaginal ultrasound,” says the National Library of Medicine.

The United Kingdom’s National Health Service also says that “the heart is forming as a simple tube-like structure” around the fifth week and “[the] baby already has some of its own blood vessels and blood begins to circulate.”
