It's a phenomenon that if a woman, A, spends time around a woman, B, who is either pregnant or has a young baby (B is perhaps a sister, friend), sometimes woman A finds herself with "a desire to have a baby or another baby".
(This trope often features in both serious or comedy shows and films, or indeed, in everyday life.)
In English you usually somewhat humorously refer to this as being "clucky" or "broody" (from the words used with female birds).
(If you're not a native speaker and not familiar with this, you can find endless examples by googling the words, eg https://www.stuff.co.nz/life-style/parenting/pregnancy/66023277/you-know-youre-clucky-or-broody-when )
In short ...
are there really any synonyms or alternatives at all for this phenomenon, other than the two slang-ish ones?
(I've checked all the usual thesauri - the problem is they tend not to include jokey terms like "clucky", and for "broody" you get the unrelated senses.)
Essentially, they are both jokey/informal - so how do you say it in a non-jokey way?
In particular, there has surely been any amount of scientific, psychological / sociological study of this, scholarly articles, so perhaps there's actually a scientific term in use in such papers - which is indeed the ideal thing I'm after.
(I have the usual access to such things, but I know little/nothing about the medical field so I really have "failed to google it" after hours.)
If we just happen to have someone like Dr. McKay on this list, we should get an answer!
Surely there's some more formal way to describe this?
