Researchers develop new period product that solidifies blood
The biomaterial could improve the performance of current period products, including pads and menstrual cups

A team of US researchers has developed a biomaterial designed to improve the performance of current period products by making the blood harder to spill out.
Researchers at the Virginia Polytechnic Institute and State University developed the blood absorbent biomaterial with the aim of improving the performance of menstrual products by minimising blood leakage and spilling.
The innovation, the team says, should help prevent infection, while also being environmentally friendly.
Lab leader Bryan Hsu, assistant professor of biological sciences, wanted his next project to focus on an area of research that had long been neglected and that’s when he landed on menstruation.
“It’s something that people don’t feel comfortable talking about, and that’s maybe an indication of why it hasn’t gotten enough attention,” he explained.
Menstrual products have evolved little during the last century. The primary products available today were developed nearly 100 years ago: the disposable menstrual pad in 1888, the tampon in 1933, and the menstrual cup in 1937.
Postdoctoral associate Harsimran Kaur, who led the project, said: “There is very little awareness about the importance of good menstrual care, and poor practices can negatively affect women’s health. This is an area that impacts women but isn’t often given attention.”

Hsu and the team used an alginate-glycerol powder formula that, when added to a traditional menstrual pad, allows the accumulated blood to turn into a gel. The pad can then absorb more blood and leak less than a traditional pad.
“A pad with the powder formula absorbs the blood, and if you squeeze it, it doesn’t come back out. But in a normal menstrual pad, if you do the same experiment, it comes right back out,” he explained.
When the powder formula is added to a cotton coil and inserted into a menstrual cup or disc, the blood collected there also turns into a gel, eliminating the mess when removing or changing the cup or disc.
Carrie Champine, board-certified obstetrician and gynaecologist who collaborated with the team, said: “Leakage is a fear for all users of menstrual hygiene products. All of us have experienced it, leading to embarrassment and missed school days and workdays.
“Users of menstrual products are always looking for products that are comfortable and tailored to their body and flow patterns, with minimal risk of leakage or menstrual product failure.”
Findings have shown the powder formulation, which is derived from natural sources, seaweed, and sugar alcohol, is biodegradable and safe to use.
“It’s found everywhere in foods and it’s approved by the Food and Drug Administration (FDA), so it’s considered safe,” said Hsu. “It is in the boba tea or the cheap sushi you get in restaurants.”
Unlike most used period products, which take over 500 years to biodegrade, this method is also environmentally friendly, the researcher noted.
Women’s health progress
According Hsu, as of 2020, 46 per cent of women in Virginia are of menstrual age, which is 26 per cent of all Virginians, and roughly a fourth of the state’s total population. While menstruation is not a disease, it does impact absenteeism in the workplace and in school.
“A woman will have a period for approximately five days every 30 days throughout her lifetime, which is roughly 2,200 days, or 6.2 years of her life,” he explained. “For comparison, the average American spends 8.3 years watching television and 4.5 years eating.
“Women are half the population and go through menstruation every month. It’s a natural process that dramatically affects quality of life. For some, it can be debilitating,” he added.
Hsu sees this as just the beginning of his venture into promoting women’s health issues.
“I think women’s health is becoming more and more something people want to research. This is kind of my first step in a series of things to take care of women.”
His colleague, postdoctoral associate Rogerio Bataglioli, who led the project, is hopeful for new opportunities in the design of menstrual products.
“Using biomaterials can expand the potential functionality of these menstrual products,” Bataglioli said.
“Women face an array of challenges related to menstrual health, and we think using advanced functional materials can help us come up with innovative solutions.”

Spain football federation partnership to offer players egg-freezing and fertility treatment

Spain’s football federation will offer national team players egg-freezing and fertility treatment through a clinic partnership running until 2029.
The agreement with the Tambre clinic in Madrid will give Spain’s World Cup winners more options to pursue motherhood when they feel the time is right.
The Royal Spanish Football Federation (RFEF) said the agreement covers all national team players, including the futsal team, as well as Primera Division referees and assistants and all other federation employees.
It is the latest policy introduced by the RFEF as it seeks to lead the way in work-life balance and maternity protection.
The federation has also introduced measures allowing players to travel with their children during major tournaments. The scheme was extended to the men’s team during their successful World Cup campaign in North America this past summer.
RFEF president Rafael Louzán said: “If Spain and its national teams are the best in the world on the pitch, they must also be the best in matters such as work-life balance.
“This is a new, comprehensive and pioneering benefit that extends to all federation employees. Today is a great day for the entire Spanish football family.”
The agreement followed a direct request from players after discussions with national team captains, including London City Lionesses midfielder Alexia Putellas.
Putellas told Spanish outlet El País: “As a group of captains, we had a concern — because experiencing a World Cup is vital for a player — regarding the difficulty of reconciling that with the desire to become a mother.”
“It’s a desire I didn’t originally have but developed some time ago.
“Thanks to the incredible work done by the federation, an agreement has been reached with a clinic allowing us to freeze our eggs while we are still active players, for as long as we wish.
“For me, this is a huge step forward; the federation understands that you are serving your country in a way that runs counter to your biological clock — that you can’t simply pause your career to become a mother because you need your body to do your job.”
The announcement follows Chelsea becoming the first Women’s Super League club to offer similar fertility treatment options to its players.
The move has also drawn criticism.
Spanish triple jumper Ana Peleteiro-Compaoré Brión said on Instagram: “The problem obviously isn’t freezing eggs.
“The problem is: why does the institution these women work for have an interest in financing them to delay their motherhood?
“And here there’s a problem that for me changes absolutely everything.
“Is this measure intended to make it easier for women to be mothers or is it intended to make it easier for them not to be while they’re playing?”
Spain are the current world champions in both the women’s and men’s games.
The women will attempt to defend their title at the 2027 World Cup in Brazil next summer.
Menopause
High street bakery chain Gail’s reveals menopause plan

Gail’s has unveiled a menopause action plan offering new workplace support to thousands of staff ahead of legal reforms due in 2027.
The high street bakery chain will offer new benefits including 24/7 digital GP access and a new employee assistance programme, according to The Times.
It will also explore new online training for staff, including specific training for management.
Gail’s people director Miranda Burgum told The Times: “All we’re trying to do is talk freely and for it not to be a forbidden subject. It’s helping our managers and teams understand that this isn’t a taboo.”
“We’re going to develop the education with our managers, so it will be threaded through all our policies
“It will look at induction training, it will look at the types of people we need to make sure that we make reasonable adjustments for.
“And if somebody needs some sort of risk assessment, we’re going to be looking at [that].”
The move comes ahead of reforms due to be introduced in spring 2027 under the Employment Rights Act.
UK employers with 250 or more employees will be legally required to publish and update official menopause action plans.
The plans are intended to support employers to take effective action to improve workplace gender equality and support employees experiencing menopause.

Paracetamol use may impact future fertility, studies suggest

Paracetamol use in pregnancy was not linked to autism or ADHD, while separate research found reproductive differences in girls exposed before birth.
One study analysed health records from more than 120,000 children and found no increased risk of autism following prenatal paracetamol exposure.
A separate analysis of nearly 100,000 children also found no increased risk of ADHD among those born to mothers who used the painkiller during pregnancy.
Researchers from the Hong Kong Hospital Authority examined electronic health records covering pregnancies between January 2001 and December 2023.
The autism analysis included 124,333 children, who were nine years old on average and split almost evenly between males and females. There were 3,445 autism diagnoses, representing 2.8 per cent of the group.
The ADHD analysis involved 97,285 children, who were seven years old on average and also split evenly between males and females. There were 5,168 ADHD diagnoses, representing 5.3 per cent.
Women prescribed paracetamol during pregnancy were more likely to be older and have pre-existing conditions including psychiatric disorders, as well as reasons for taking the drug such as infection, fever or chronic pain.
No association was found between prenatal paracetamol exposure and either autism or ADHD.
The findings did not differ according to the trimester in which paracetamol was taken or whether use was intermittent or daily. Advanced maternal age, defined as pregnancy in women over 35, did not alter the findings.
The researchers wrote: “Paracetamol remains a safe and essential analgesic [pain reliever] and antipyretic [fever reducer] during pregnancy, whereas alternatives, such as NSAIDs and opioids carry well-documented risks.
“Unwarranted reluctance to use paracetamol could lead to undertreatment of pain and fever, or the use of more harmful alternatives, both posing risks to the pregnancy and developing fetus.”
The authors said women should assess paracetamol use with guidance from their doctor.
A separate study involving 685 pregnant women without pre-existing conditions and 302 infant daughters found associations between prenatal paracetamol exposure and differences in reproductive organs and hormone levels.
Researchers from Copenhagen University Hospital enrolled the women during their first trimester and assessed them during the first trimester, third trimester and again when their babies were three months old.
At around three months, infants experience a temporary rise in reproductive hormones sometimes called mini-puberty.
Pregnant participants completed questionnaires every two weeks about their use of pain medicines including paracetamol. Infant girls underwent ultrasound scans of their reproductive organs and blood tests to measure hormone levels.
Researchers also examined a separate group of 1,210 girls followed from infancy to adolescence whose mothers reported paracetamol use during the third trimester.
Three-month-old girls exposed to paracetamol before birth had an average 40 per cent smaller ovarian volume, 13 per cent smaller uterine volume and 23 per cent fewer ovarian follicles.
Girls exposed during the first trimester also had lower levels of Anti-Müllerian hormone, a marker of ovarian function.
Among the older girls, those exposed before birth were more likely to have smaller uteruses at puberty and smaller ovaries during their teenage years.
Dr Margit Bistrup Fischer, lead study author and postdoctoral researcher in the Department of Growth and Reproduction at Rigshospitalet hospital in Denmark, said: “Animal studies have demonstrated that impaired formation of ovarian follicles can lead to reduced fertility and earlier reproductive aging.
“Whether the differences observed in our study have implications for fertility and age at menopause in humans remains unknown and will require long-term follow-up of the girls in our cohort.”
She cautioned that women who had used paracetamol during pregnancy “should not be alarmed by our findings”, as the study found associations rather than direct causation and outcomes for individual women and children are unclear.
“Importantly, our study does not evaluate whether [acetaminophen] causes reproductive problems, nor does it provide evidence that prenatal exposure affects future fertility or age at menopause,” she said.
“Although we observed similar associations in an independent cohort, long-term follow-up is needed to determine whether these early-life differences have any clinical significance later in life.”
