Plummeting fertility rates and ageing societies will see nurseries replaced by nursing homes
Media Release, 18 May 2026
The world is entering an epoch in which baby nurseries will be progressively replaced by nursing homes creating an enormous burden on young workers to generate taxable income to support swelling ranks of the elderly.
This grim forecast has been presented at a global conference on assisted reproduction as countries around the world face alarming falls in total fertility rates.
Speaking at the 2026 Congress of the Asia Pacific Initiative on Reproduction (ASPIRE) in Beijing, Bangladeshi fertility specialist Professor Nusrat Mahmud said population fertility health was in crisis on multiple fronts primarily from negative effects of climate change, pollutants and endocrine disrupting chemicals (EDCs).
She said there was growing awareness that global warming could negatively influence reproductive health in men and women with links to sperm abnormalities and abnormal ovulation.
Professor Mahmud, a senior consultant in the Division of Reproductive Medicine and Infertility at Birdem General Hospital in Dhaka, said the World Health Organisation projected 250,000 additional deaths from climate sensitive diseases between 2030 and 2050.
She told the ASPIRE Congress the true impacts on human reproductive health through global warming and exposure to environmental and occupational pollutants and EDCs were not fully understood.
But Professor Mahmud particularly highlighted a likely nexus between the “warming world” and pollutants with a sharp decline in male sperm counts along with increasing levels of sperm fragmentation associated with poor embryo development and recurrent miscarriages.
“Evidence suggests sperm counts have fallen by over 50 per cent in the past forty years,” she said. “The average male today may face different fertility challenges to the average male of two generations ago.
“The big question is no longer whether this so called spermageddon is really happening, but why and what can we do about it?
“Ignoring the potential decline in semen quality and its causes can lead to irreversible damage to human and planetary health with trans-generational impacts.”
Total fertility rates across the world are plummeting, particularly in the Asia Pacific region where the number of births has fallen below population replacement levels.
This poses serious social and economic challenges as population age dependency increases and there are fewer young people to support aged care economic demands.
Professor Mahmud has specialised in research on climate change on infertility in the South Asian region.
Bangladesh is one of the most vulnerable countries to climate change. It is ranked second in global exposure to elevated temperatures with Dhaka especially singled out for urban heat.
The Birdem Hospital in Dhaka has collaborated with the Emory University in the United States in a study on a decline in semen parameters, including sperm concentration and motility among Bangladeshi men and similar observations in the global community.
“Azoospermia, or total absence of sperm in a man’s ejaculate, has been consistently increasing among Bangladeshi men for the past two decades,” Professor Mahmud said.
“We have done another study with data collected from Pakistan and India and there were higher trends of azoospermia in Bangladeshi men than among their neighbours.
“Male infertility is a complex biological and social phenomenon, and the world must act on the impacts of global warming, environmental pollutants and EDCs.”
Over 3,000 fertility specialists from across the globe attended the ASPIRE Congress in Beijing.
