Surprise Pregnancies After 40: Swiss Study Reveals Widespread Misconceptions
LAUSANNE, Switzerland – October 5, 2025 – A startling new report from Switzerland reveals a persistent and dangerous misconception: that women are no longer fertile after age 40. Contrary to popular belief, and even the advice some receive from medical professionals, unplanned pregnancies in women over 40 are not only common but remain stable – and even above average – compared to other age groups. This breaking news challenges long-held assumptions and highlights a critical gap in public and medical understanding of female reproductive health.
The Myth of Infertility After 40
For decades, the narrative has been that fertility sharply declines with age, and while that’s true to an extent, it doesn’t equate to infertility. Dr. Hélène Legardeur, head of the polyclinic for gynecology and obstetrics at the University Hospital Lausanne, explains, “Many people believe that from 42 or 43 years of age you can no longer get pregnant. I keep finding that a large part of the women believes that they are naturally protected from pregnancy at this age.” This belief leads to a significant number of women foregoing contraception, assuming they are no longer at risk.
Switzerland’s Unexpected Trend
While teenage pregnancies in Switzerland are decreasing, the number of unplanned pregnancies among women over 40 remains stubbornly consistent, accounting for roughly 6-7% of all pregnancies – a figure that includes those achieved through assisted reproductive technologies like IVF and egg donation. This suggests a widespread underestimation of natural fertility even as assisted reproduction becomes more prevalent. International data mirrors this trend, indicating this isn’t a localized issue.
Why the Confusion? A Breakdown of the Biology
The core of the misunderstanding lies in the definition of menopause. It’s not simply reaching a certain age; menopause is officially diagnosed after 12 consecutive months without menstruation, accompanied by characteristic symptoms like hot flashes. As long as a woman is still experiencing regular cycles, there’s a chance of ovulation and, therefore, pregnancy. “As long as the patient is not really in the menopause, there can still be an egg cell in the ovary somewhere that can hit a sperm after ovulation,” Dr. Legardeur emphasizes.
The Psychological Factor & Post-Fertility Treatment Surprise
The report also highlights a fascinating psychological dimension. Women who have struggled with infertility and finally conceive, often through lengthy and expensive treatments like IVF, sometimes assume their fertility journey is over and discontinue contraception. Dr. Legardeur notes that spontaneous pregnancies can – and do – occur even after years of assisted reproduction, with the likelihood of natural conception at 42 sometimes *higher* than through assisted methods (excluding donations). The sheer relief of finally achieving pregnancy can lead to a lapse in preventative measures.
A Call for Better Education & Medical Awareness
The study points to a need for improved sex education in Switzerland, not just for the general public but also for medical professionals. Dr. Legardeur recounts instances of patients being told by their doctors that the chance of pregnancy at their age is low, leading to a false sense of security. “If a tube ligature, i.e. a sterilization, has been carried out, it cannot happen that you get pregnant – otherwise I do not see why a woman who is not yet in menopause should not be pregnant,” she states, underscoring the basic biological reality.
Pregnancy After 40: Risks and Realities
While spontaneous pregnancy after 40 is often a sign of overall health, it’s crucial to acknowledge the slightly increased risks associated with advanced maternal age. However, these risks are often overstated. Spontaneous pregnancies generally carry a lower risk profile than those achieved through assisted reproduction. With proper prenatal care, most women over 40 experience healthy pregnancies and deliver healthy babies.
This report serves as a vital wake-up call, urging a more informed and nuanced understanding of female fertility. It’s a reminder that reproductive health is a lifelong journey, and that misconceptions can have significant consequences.
