If you step back for a second, you are claiming that billions of people are insane.

Taking a singular, highly-specific (in the context of humanity and for the thousands of years that Catholicism has existed) issue and conflating it to insanity or sanity is, perhaps, insane in of itself.

Single individuals are usually sane. But when they form a superstitious groups they those groups believe and do insane things no single individual would.

In the long run, culture like genes is to a large degree spread by reproductive success. Religions/belief systems that discourage reproduction eventually die out to be replaced by those that encourage it. All liberal/secular cultures currently have below-replacement birthrates, and hence will eventually be replaced by less liberal ones. So by the raw logic of evolution, it's very sane for religions to discourage lifestyles that lead to less childbirth, as to prolong their lifespan they need their adherents to keep having more children than adherents of competing ideologies.

Then why is the Catholic Church opposed to IVF? Let’s not pretend that there’s some sort of grand Darwinist scheme behind its sexual mores. Like most religions, reproduction is encouraged within particular constraints, and these are not such as to maximize the total amount of kids people are having.
