Summary • They did not differ in physical or mental functioning compared to the younger women. • They did not suffer from greater parenting stress. Conclusions • Older parents adapt to parenting in a similar fashion as their younger counterparts. • The paternal contribution to childrearing among these couples should be further explored. • The physical and mental capacity of these women should not be considered an early impediment to childrearing. • Postmenopausal reproduction should not be restricted based on concerns of parenting stress. Long-term follow-up Arceli Keh • World’s oldest mom at 63 in 1997 • Lied about her age • Treated in US • Alive and well Carmela Bousada • Oldest mom at 67 in 2007 • Lied about her age • Treated in US • Died in 2009 of cancer Omkari Panwar World’s oldest mom at 70 Wanted male child Twins (boy-girl) at 32 weeks by emergency C-section Severe pre-eclampsia Rewinding the biological clock • Parallels societal changes – Perception of aging – Expectation of aging – Individual rights and autonomy – Reproductive choice Oocyte donation • Most successful of ARTs • Overcomes agerelated decline in fertility • Pregnancy possible in virtually any woman with a uterus Aging in perspective Do not go gentle into that good night, Old age should burn and rave at close of day; Rage, rage against the dying of the light.
