** More likely it's a consequence of development. Good healthcare improves lifespans but also reduces infant mortality, meaning people don't need to have as many children to guarantee some survive. More developed countries also tend to have less of a primary-industry focus meaning children are a net drain on assets rather than a source of income. State welfare and wealth in general also means parents aren't as reliant on children to support them in their old age.
* Because human oocytes (eggs) are produced by a woman's ovaries before she, herself, is born, an immortal woman's capacity for natural reproduction would inevitably expire when her supply runs out, even if she never goes through menopause (assuming the science at some point won't be able to reboot the ova production mechanism, of course). She could, however, give birth to a baby conceived ''in vitro'' from a donor egg.
* An [https://getpocket.com/explore/item/a-zombie-gene-protects-elephants-from-cancer?utm_source=pocket-newtab article by Viviane Callier about cancer in elephants] describes a 2009 study suggesting a tradeoff between cancer suppression and fertility. Larger and longer-lived animals need to dial up the measures against mutations (DNA copying mistakes) that lead to cancer, and these measures interfere with pathways involved in reproduction.
