Scotland university set to study new contraceptive method after bagging US$4.4m grant
The new contraceptive method that slows down sperm will first be trialled on women, say researchers
A team of Scottish researchers have received a US$4.4m grant from the Bill & Melinda Gates Foundation to help discover a new contraceptive that would slow down sperm in the female reproductive system.
The team from the University of Dundee have discovered chemical combinations that stall sperm so that they will never be able to swim far enough to fertilise an egg.
The researchers have screened “drug libraries” to detect combinations that can disable sperm without being toxic and have so far spotted two potential candidates.
“These compounds stop the sperm swimming fast,” explained Professor Chris Barratt of the School of Medicine.
“The sperm will move, it will still twitch, but it will not make any headway. It is a car that is moving in the slow lane. It will never get anywhere, it is almost too slow to see — but it is not dead so [the compound] is not toxic to the cell.”
But although the compounds would affect the sperm, the Bill & Melinda Gates Foundation grant is intended to help turn the chemicals into treatments that could be given to women in the form of a pill, patch or gel.
“My understanding is the Gates foundation wants this contraceptive approach to be taken by the female not the male,” Barratt told the Times.
“Obviously if we find something interesting that affects the sperm you can see if that can be taken by the male but our focus is on the female tract.”
He added: “Our ultimate aim is to produce a non-hormonal contraceptive for women, improving contraceptive choice, particularly for those in low and middle income countries.
“If we find products that affect sperm cells, it may be they could be developed for the man.”
Data suggest that between 2015-19, there were 121 million unintended pregnancies, with women living in the world’s poorest regions nearly three times as likely to fall pregnant unintentionally, in comparison to those in the wealthiest regions.
However, the need to develop further forms of contraception have previously been hampered by the relatively poor understanding of human sperm biology and the absence of an efficient system to screen the effects of potential drug compounds on sperm activity.
Jason Swedlow, Professor of Molecular Cell and Developmental Biology, said: “We really know very little about how sperm cells work.
“It is technically very challenging to develop potential new drugs which affect sperm. To do this we have had to develop new ways to measure the effects of compounds on sperm.”
The University of Dundee aims to study this matter by bringing together experts in reproductive medicine, drug discovery, mechanism of action and cell biology.
Ian Gilbert, head of the drug discovery unit, said: “A project of this complexity can’t be undertaken without the extensive, collaborative capability that exists here at Dundee.
“We all contribute our unique skillsets, and all of the key decisions are decided between us. This is hugely complex work, and to have such a broad range of input is hugely advantageous.”

Women with osteoporosis may be more likely to carry a gene linked to Alzheimer’s, according to new research.
Scientists found that APOE4, the most common genetic risk factor for Alzheimer’s, can weaken bone quality in women, even when standard scans appear normal.
The study, carried out by researchers at the Buck Institute for Research on Ageing in California, US, and UC San Francisco, suggests the gene may damage bone at a microscopic level long before any visible signs.
These changes can emerge as early as midlife and remain invisible to routine imaging tests used to assess bone strength.
The findings suggest a link between Alzheimer’s risk and skeletal health and could help pave the way for earlier detection of both conditions.
Professor Birgit Schilling, a senior author of the study, said: “What makes this finding so striking is that bone quality is being compromised at a molecular level that a standard bone scan simply will not catch.
“APOE4 is quietly disrupting the very cells responsible for keeping bone strong – and it is doing this specifically in females, which mirrors what we see with Alzheimer’s disease risk.”
Doctors have long observed that people with Alzheimer’s suffer higher rates of bone fractures, while osteoporosis in women is known to be one of the earliest predictors of the disease.
Now scientists believe they may have uncovered why.
Researchers led by Dr Charles Schurman carried out a detailed analysis of proteins in aged mouse bone and found that tissue was unusually rich in molecules linked to neurological disease, including those associated with Alzheimer’s.
In particular, long-lived bone cells known as osteocytes showed elevated levels of APOE, with levels twice as high in older female mice compared with younger or male animals.
Further experiments using genetically modified mice revealed that APOE4 had a strong and sex-specific impact on both bone and brain tissue.
The disruption at the protein level was even greater in bone than in the brain.
However, the bone structure itself appeared completely normal under scans.
Instead, the gene interfered with a key maintenance process inside bone cells, preventing them from repairing microscopic channels that keep bones strong and resilient.
When this process breaks down, bones become more fragile even if they look healthy on standard imaging.
These results suggest bone cells could potentially act as early biological warning signs of cognitive decline in women carrying APOE4.
Professor Lisa Ellerby, another senior author, said: “We think targeting these cells may open a new front in preserving bone quality in this population.”
Experts say the findings highlight the need to view the body as an interconnected system rather than treating diseases in isolation.
Dementia, of which Alzheimer’s is the most common form, remains one of the UK’s biggest health challenges.
Around 900,000 people are currently living with the condition, a figure expected to rise to 1.6 million by 2040.
It is already the leading cause of death, responsible for more than 74,000 deaths each year.
Health secretary Wes Streeting has relaunched England’s women’s health strategy, vowing to stop women being “gaslit” by doctors.
Speaking before publication of the renewed strategy, the health secretary said the NHS was “failing women” and set out measures to help them access the healthcare they need.
The government said the strategy would include a new standard of care to ensure women were offered pain relief for invasive procedures, such as fitting a contraceptive coil and hysteroscopies.
Feedback would be directly linked to provider funding through a new trial, giving women more power to affect change if they have a poor experience.
Action would also be taken to ensure women no longer face long waits for diagnoses for conditions such as endometriosis, which can take a decade to diagnose.
Streeting said: “[Women] have for so long been let down by a healthcare system that too often gaslights women, treating their pain as an inconvenience and their symptoms as an overreaction.
“Whether it’s being passed from one appointment to another for conditions like endometriosis and fibroids, or a lack of proper pain relief during invasive procedures, through to having to navigate symptoms for years before receiving a diagnosis, it’s clear the system is failing women.
“Women’s voices must be central to delivering effective, respectful and empathetic care. We need to hit medical misogyny where it hurts – the wallet.
“Today’s renewed strategy will tackle the issues women face every day and ensure no woman is left fighting to be heard.”
A report last month by the women and equalities committee found that gynaecological and menstrual health had not been “sufficiently prioritised” by the government.
MPs said parts of the 10-year women’s health strategy, launched in 2022 by the Conservatives, were at risk of being scaled back or discontinued under wider changes to the NHS.
These included initiatives that had reduced waiting lists and improved women’s access to healthcare, such as women’s health hubs.
Sarah Owen, chair of the committee and a Labour MP, said: “This would be a disaster for girls’ and women’s menstrual healthcare, when it is in dire need of more support.
“It is a national scandal that nearly half a million women are on hospital gynaecology waiting lists when there are effective treatments that could be administered in primary and community care, if only they could access them.”
The report said women faced “medical misogyny” and were left to “suck it up” and suffer in pain for years because of a lack of awareness of women’s health conditions.
A redesign of clinical pathways for some women’s health issues will aim to speed up diagnosis and treatment, and there will be a review of support for families who experience repeated baby loss.
The government also promised a “single referral point” to ensure women were directed to the right place the first time they sought help.
Dr Sue Mann, NHS England’s women’s health director, said too many women were dismissed for “serious symptoms” that affected every part of their lives.
“The renewed women’s health strategy will build significantly on the work the NHS has been doing to ensure women are heard and get the specialist care they need,” she said.
Women’s health groups cautiously welcomed the renewed strategy. Emma Cox, chief executive of Endometriosis UK, said decisive action would be vital to improve women’s healthcare in England.
