London, England, Nov 22, 2025 / 06:00 am (CNA).
Many women in England and Wales who have abortions in their 20s may end up childless in their 40s, according to key research by a pro-life activist and former employee of Marie Stopes International.
A report issued by Catholic independent public health consultant Kevin Duffy titled “Abortion and Childlessness” shows that many women who have abortions in their 20s may be faced with the real risk of remaining childless at 45. However, Duffy states that this risk is rarely, if ever, highlighted by abortion providers to those considering abortion.
Duffy’s projections in the report suggest that, by 2045, as many as 1 in 4 women may reach the age of 45 having not given birth to any children, with abortion given as a major factor in about half of these cases.
While Duffy does not suggest abortion causes infertility, his data shows that if an abortion leaves a woman childless at 30, she may find herself in a situation where timing pressures and a natural decline in fertility become major factors, leading to a 50/50 chance she will still be childless at 45.
One troubling statistic from the Office for National Statistics (ONS) showed that in 2022, women aged up to 25 had a total of 190,970 conceptions, of which 90,753 — 48% — ended in abortion. These figures highlight how Gen Z (people born between 1997 and 2012) approaches procreation and family planning, with abortion playing a significant role in this approach.
The report pinpoints concerns over declining fertility rates. Duffy states: “In 2022, it is very likely that more than 5,000 childless women aged 29, presenting for an abortion, were not warned of the 50% chance that they would remain childless at 45.”
The Office for National Statistics (ONS) showed in August 2025 that the total fertility rate (TFR) in 2023 in England and Wales was 1.41, which was described as “the lowest value on record for the third year in a row.” Duffy highlights the fact that, since 1973, the TFR total has remained below the replacement level of 2.1 and has dipped dramatically since 2012. He shows that abortion plays a role in about half of all childlessness.
“Abortion is a significant factor in the falling birth rate,” Duffy told CNA. “Women are still having broadly the same number of children. The average hasn’t really changed [since the 1970s]. It’s still around about 2.3, even though the fertility rate has been plummeting. And that plummeting is because childlessness has been increasing.”
During his research, Duffy found that, of women up to the age of 30 who had remained childless, about half have had abortions. Regarding this risk, he said: “They need to be told. Abortion providers should be letting them know that there is a risk. That abortion may be ending the only chance you have of becoming a mother.”
Noting that a continued plummeting fertility rate will have grave consequences for society, Duffy — who previously helped Marie Stopes International promote abortion in Africa and Asia — believes action is necessary.
“From workforce shortages to an unsustainable age structure, the consequences will be far-reaching. If we are to address this issue responsibly, we must confront all contributing factors — including the role of abortion — with honesty and urgency.”
Focusing on abortion, Duffy — who is now firmly pro-life — said “a risk this high demands to be fully investigated and women need to be told.”
Duffy’s report comes at a critical time for the pro-life movement in the U.K.
A highly controversial abortion up to birth amendment was inserted into the U.K. government’s Crime and Policing Bill earlier this year. If this amendment becomes law, it would mean women would be legally allowed to perform their own abortions for any reason at any point of pregnancy. This would raise the alarming risk of women performing their own late term- abortions in their homes.
Isabel Vaughan-Spruce, a Catholic pro-life activist who has been repeatedly arrested for praying silently near an abortion facility in Birmingham, England, underlined the Catholic teaching that life begins at conception.
Vaughan-Spruce told CNA: “When discussing ‘childlessness,’ we frequently overlook a crucial fact: Many women counted as childless have conceived a child but have then had an abortion. The truth is that life begins at conception, meaning motherhood and fatherhood begin then as well. No act, not even abortion, can erase that reality.”
“Doctors are careful to emphasize the permanence of sterilization but rarely acknowledge the lifelong impact of abortion. Each conception brings into existence an irreplaceable human being whose loss leaves a real absence in both family and society.”
Commenting on Duffy’s findings, Andrea Williams, chief executive of Christian Concern’s Christian Legal Centre, said: “Abortion providers fail to give women the full picture of what the choice to abort will mean for them in the long term. How many women would make different decisions if they knew of the 50/50 chance that they would never have children?”
Duffy called on the Church to support pregnant women so that “they don’t feel so much pressure” to have an abortion. Duffy said: “What can we do, as a Church, to give that moral, emotional, and spiritual support to young parents? How can we support our young people to become parents and to have more children?”
The Catholic Bishops’ Conference of England and Wales in a Nov. 14 statement confirmed its opposition to decriminalize abortion, describing it as “an assault on the value of human life” and calling for laws that “protect life, preserve human dignity, and promote the common good.”
