Here's an example of how you might use it in a sentence, emphasizing its outdated and controversial nature:
"The phrenologist claimed that her client's large bump on the top of his head indicated a strong philoprogenitiveness, suggesting he was destined to have a large family."
It's important to note that the term "philoprogenitiveness" carries with it the baggage of a pseudoscientific theory and is generally not considered appropriate for everyday language.
Instead, you could use more modern terms like:
* Parental instinct
* Desire to have children
* Love for children
* Nurturing nature
These phrases are more accurate and avoid the association with the discredited field of phrenology.
