Bryan Hsu is tackling an space of analysis that has lengthy been uncared for—menstrual merchandise.
“It is one thing that individuals do not feel comfy speaking about, and that is perhaps a sign of why it hasn’t gotten sufficient consideration,” mentioned Hsu, assistant professor of organic sciences.
Matter, Hsu and his workforce, which incorporates postdoctoral associates Rogerio Bataglioli and Harsimran Kaur that led the mission, have created an eco-friendly, blood absorbent biomaterial that improves the efficiency of menstrual merchandise by minimizing blood leakage and spilling, whereas additionally serving to forestall an infection. Their work was published within the journal Matter.
Menstrual merchandise have advanced little over the last century. The first merchandise out there as we speak have been developed almost 100 years in the past: the disposable menstrual pad in 1888, the tampon in 1933, and the menstrual cup in 1937.
“Creating new merchandise serves a number of functions, together with addressing girls’s totally different wants and preferences, selling sustainability, and addressing leakage and price points with present merchandise,” mentioned Carrie Champine, board-certified obstetrician and gynecologist who collaborated with the workforce.
An enchancment in girls’s sanitary merchandise is helpful to girls’s well being normally.
“There may be little or no consciousness in regards to the significance of fine menstrual care, and poor practices can negatively have an effect on girls’s well being. That is an space that impacts girls however is not usually given consideration,” Kaur mentioned.

Improved effectiveness
Hsu and the workforce used an alginate-glycerol powder formulation that, when added to a conventional menstrual pad, permits the amassed blood to show right into a gel. The pad can then take up extra blood and leak lower than a conventional pad.
“A pad with the powder formulation absorbs the blood, and for those who squeeze it, it would not come again out. However in a standard menstrual pad, for those who do the identical experiment, it comes proper again out,” mentioned Hsu, who can be an affiliate of the Fralin Life Sciences Institute. “Leakage happens 1.2 occasions per cycle.”
When the powder formulation is added to a cotton coil and inserted right into a menstrual cup or disk, the blood collected there additionally turns right into a gel, eliminating the mess when eradicating or altering the cup or disk.
“Leakage is a concern for all customers of menstrual hygiene merchandise. All of us have skilled it, resulting in embarrassment and missed college days and workdays,” mentioned Champine, who can be an affiliate dean within the Edward Through Faculty of Osteopathic Drugs. “Customers of menstrual merchandise are at all times in search of merchandise which might be comfy and tailor-made to their physique and circulate patterns, with minimal danger of leakage or menstrual product failure.”
Safety measure
When interval merchandise should not out there or sanitary interval merchandise unaffordable, girls could improvise with managing menstruation. These substitutions could trigger extra hurt than good by growing vaginal infections.
Included within the powder formulation is an antimicrobial polymer to impair the expansion of Staphylococcus aureus, a bacterium related to poisonous shock syndrome. This can be a uncommon however doubtlessly deadly sickness attributable to a bacterial an infection associated to using interval merchandise.
Check outcomes point out the inclusion of the polymer was efficient in inhibiting micro organism, whereas additionally not reducing the blood absorption functionality of the powder formulation.
Biodegradable possibility
Derived from pure sources, seaweed, and sugar alcohol, the alginate-glycerol powder formulation is biodegradable and secure to make use of.
“It is discovered all over the place in meals and it is authorized by the Meals and Drug Administration, so it is thought of secure,” mentioned Hsu, an affiliated school member of the Heart for Rising, Zoonotic, and Arthropod-borne Pathogens. “It’s within the boba tea or a budget sushi you get in eating places.”
Most used interval merchandise take over 500 years to biodegrade, and every girl could use as much as 15,000 interval merchandise in a lifetime, in response to Hsu, who additionally mentioned girls’s menstrual product waste is without doubt one of the most regularly collected trash.
“In speaking to sufferers, it has turn out to be evident that they’re in search of extra sustainable, eco-friendly and reusable choices,” Champine mentioned.
Girls’s well being progress
“Girls are half the inhabitants and undergo menstruation each month,” Hsu mentioned. “It is a pure course of that dramatically impacts high quality of life. For some, it may be debilitating.”
In response to Hsu, 46% of ladies in Virginia are of menstrual age, which is 26% of all Virginians, as of 2020 and roughly a fourth of the state’s whole inhabitants. Whereas menstruation will not be a illness, it does impression absenteeism within the office and at school.
“A lady can have a interval for about 5 days each 30 days all through her lifetime, which is roughly 2,200 days, or 6.2 years of her life,” Hsu mentioned. “For comparability, the common American spends 8.3 years watching tv and 4.5 years consuming.”
Hsu sees this as just the start of his enterprise into selling girls’s well being points. Bataglioli is hopeful for brand spanking new alternatives within the design of menstrual merchandise. “Utilizing biomaterials can develop the potential performance of those menstrual merchandise. Girls face an array of challenges associated to menstrual well being, and we expect utilizing superior useful supplies can assist us give you progressive options.”
“I feel girls’s well being is changing into increasingly more one thing folks need to analysis. That is sort of my first step in a sequence of issues to deal with girls,” Hsu mentioned.
Along with Hsu, Bataglioli, and Kaur, organic sciences undergraduate Elizabeth Geddes and John Muller, postdoctoral affiliate within the Division of Entomology have been concerned within the mission.
