Last century geriatric pregnancy was one term used for over 35s. It is no longer used, and 25 seems like it is social media bullshit. Apparently the term was created ~1960 for international usage because medical complications after that age were far more risky in the 50s.

Now ~20% of all pregnancies in the US are 35+.

Soviet doctors definitely used the term "старая первородящая" (old firstborn), google at your peril.
