I was thinking about this the other day as well, I wonder how much pet ownership in general also has a direct impact on fertility. Not fertility rates (as in, couples choosing not to have kids get pets instead), but rather toxoplasmosis effects. One counterpoint is that in previous decades, many families in certain western countries had some sort of pet but also had many children, but I wonder if living spaces becoming smaller (esp in cities) has amplified a minor effect. Anecdotally (tiny sample size of course), we know several couples trying without success, but those without pets seem to get pregnant moreso than those with.
