There are always segments in society that are laggards (slowest to adopt) or rejectors of advancements. You may have the formation of Amish-like communities that resist.

Innovations in scientific research work at a snails pace from intial innovation to accessibility of said treatment to the public.

I forgot to add the delaying of menopause or egg regeneration. But what woman wants ciyaal in her 60s. Freedom comes with retirement.
