That said, although legal scholars can have how many angels can dance on the head of a pin debates about this, the most reasonable interpretation is probably that they're US citizens/eligible for US citizenship from birth. If push ever came to shove on this question, one would hope the courts would side with the most liberal interpretation.
"The candidate is a natural born citizen by virtue of being born in Canada to his mother who was a U.S. citizen at the time of his birth."
Place of birth does not matter for the House or Senate. Only need to be a US citizen.
For the President it's a "higher standard" you must be a native born Citizen.
Which isn't 100% defined and legal scholars can and do argue the edge cases based on lots of things including very old British common law antecedents. The consensus seems to equal citizen from birth although some disagree.
"No Person except a natural born Citizen ... shall be eligible to the Office of President"
Natural born means "citizen at birth", not "born in the US"> One can also be a citizen at birth (under certain circumstances) by having parent(s) who are U.S. citizens. Ted Cruz unequivocably meets this standard.

For example, regarding Ted Cruz:
> Two November 2015 ballot challenges in New Hampshire alleging that Cruz was not a natural-born citizen were unsuccessful. In December, a similar lawsuit was filed in Vermont, and an unsuccessful lawsuit was filed in Florida. In January 2016, similar lawsuits were unsuccessfully filed in Texas and Utah, and two similar unsuccessful ballot challenges were filed in Illinois. In February, two similar unsuccessful lawsuits were filed in Pennsylvania and one was filed in Arkansas; a similar lawsuit was filed in Alabama; similar unsuccessful ballot challenges were filed in Indiana; and similar ballot challenges and an unsuccessful similar lawsuit were also filed in New York. In March, a similar lawsuit was filed in New York. In April, a similar ballot challenge was unsuccessfully filed in New Jersey.
> No lawsuit or challenge has been successful, and in February 2016, the Illinois Board of Elections ruled in Cruz's favor, stating, "The candidate is a natural born citizen by virtue of being born in Canada to his mother who was a U.S. citizen at the time of his birth."

I have no idea why you're talking about IVF children, they aren't legally different from naturally conceived children.
IVF is irrelevant if the biological parents are known and in a relationship, or if the birth is inside the U.S. In particular you cannot gain citizenship through donated sperm, though.
It should be noted that a common aspect to practically all US presidential candidates is that they all dumb down their communication style when running election campaigns, as that's a key aspect of all winning candidacies.

I was musing the other day that Elon Musk may be planning to run for president. Why? Well, if there's one thing that 2016 showed us, it's that the road to the White House runs through snubbing Wall Street, calling the press a bunch of boring liars, accusing your opponents of pedophilia, making bizarre incoherent tweet storms in the middle of the night, and bragging about the size of your rocket.
