Microplastics in Condoms & Period Products: What Women Need to Know
Written by Megan Marshall. Reviewed by the JulieMay product and garment-tech team.
Quick answer: Independent testing has found PFAS forever chemicals in roughly 14% of condoms and lubricants tested (most were PFAS-free), and many tampons and pads contain synthetic plastics, with one study estimating up to 17 billion nanoplastics released per tampon. Because genital tissue is highly absorbent, reducing exposure matters. The easiest swaps are organic cotton tampons and pads, menstrual cups, PFAS-free leakproof underwear, fragrance-free lubricants and condoms that test low for PFAS.
Recent testing on everyday products, like those used during sex or menstruation, has sparked a wave of questions about what we're putting on and in our bodies. At the centre of that discussion are PFAS (per- and polyfluoroalkyl substances) and microplastics: tiny synthetic particles and chemicals sometimes found in consumer goods, including condoms and period products.
PFAS are often called forever chemicals because they don't break down easily, and microplastics are minuscule pieces of plastic that can move through the body. This matters because genital and vaginal tissues are highly vascular, meaning they absorb substances more efficiently than ordinary skin.
So what are researchers actually finding, and what does it mean for our menstrual and sexual health?
Research on microplastics in condoms and lubricants
Consumer advocacy groups like Mamavation (partnered with Environmental Health News) sent popular condoms and lubricants to an EPA-certified lab to test for organic fluorine, a marker of PFAS, or forever chemicals. The results weren't universal, but they were certainly eye-opening: about 14% of the products contained detectable PFAS indicators, while roughly 86% showed none at all. In other words, most brands tested PFAS-free, but not all.
The issue gained even more attention when a lawsuit alleged that certain Trojan Ultra Thin condoms contained PFAS, claiming they were unsafe for intended use based on independent testing.
These findings matter because PFAS can enter the body through several routes:
- Direct skin absorption
- Increased transfer from heat or friction during sex
- Oral exposure for those who engage in oral contact with lubricated condoms
Researchers are still studying the full health picture, but PFAS are already linked to endocrine disruption, immune changes, and reproductive effects like reduced fertility and altered hormone function in both men and women.
And condoms aren't the only intimate products under scrutiny. Similar testing has raised questions about the period products many of us use every single month.
Research on microplastics in feminine hygiene products
Standard pads, tampons and period underwear often rely on synthetic polymers, absorbent plastics and chemical treatments to boost performance related to absorbency and leak prevention. But these innovations come with trade-offs.
In one study, researchers found that tampons can release microfibres and nanoplastics directly into fluid environments. Under simulated vaginal conditions, that release reached an estimated 17 billion nanoplastics per tampon.
The vagina and vulva also aren't like ordinary skin. They're lined with mucosal tissue, which is both highly permeable and richly vascularised (meaning substances can enter the bloodstream more easily). Add in PFAS and other synthetic additives found in some pads and period underwear, and you begin to see why this category is getting more scrutiny.
There's also an ecological angle here. Disposable pads are roughly 90% plastic and can take centuries to break down, contributing to landfill waste and microplastic pollution in waterways and soil. What begins as personal exposure becomes ecosystem exposure, and eventually circles back into our bodies through food and water.
All of this raises a bigger question: what does it mean for people who are trying to conceive or navigating hormone-sensitive life stages?
How microplastics may influence fertility and conception
Scientists have now detected microplastics and nanoplastics in semen, follicular fluid, placenta, breast milk and other reproductive tissues, suggesting these particles can cross sensitive biological barriers and accumulate where hormones and early development are most active.
Additionally, PFAS forever chemicals have been linked to endocrine disruption, reduced sperm quality, altered hormone signalling and lower fertilisation rates, and researchers note that PFAS exposure has been associated with pregnancy and birth outcomes in human data.
None of this means a single tampon or condom will derail fertility, but it does mean that chronic low-level exposure matters over time, especially when reproductive tissues are involved.
What's relevant for couples trying to conceive is the stacking of everyday exposures: condoms, lubricants, menstrual pads, period underwear and even synthetic underwear can all come into direct contact with genital tissue during the fertile window each month.
Emerging research has raised concerns about endocrine-disrupting chemicals and heat retention in synthetic fabrics, with animal models showing significant reductions in sperm count when males were exposed to synthetic underwear over time.
While risk levels in humans are still being studied and much remains unknown, awareness matters. Fertility isn't just a female issue, and understanding modifiable factors (especially for men) can support healthier conception outcomes.
What women in perimenopause and menopause should know
While fertility concerns are getting a lot of visibility, women in perimenopause and menopause deserve attention, too. During these life stages, shifting oestrogen levels can change how sex and daily comfort feel.
Many women in perimenopause and beyond experience vaginal dryness, thinning vaginal tissue (atrophy), burning and irritation, all of which can make certain products suddenly feel harsh or triggering. Even without regular monthly periods, many women use liners or leakproof underwear for bladder leaks, discharge or sweat. These products often contain fragrances, adhesives and synthetic fibres that can irritate already delicate, oestrogen-sensitive tissue.
And for women who are newly dating or sexually active after menopause, barrier protection still matters. STI rates are rising among older adults, and condoms remain the only method that can protect against both pregnancy and infections.
These realities set up an important question: if our bodies change with age, should our intimate products change with us?
Lower-plastic period and condom alternatives
If you're using condoms, look for brands made with fair-trade natural latex and without PFAS. Mamavation's testing identified several options that performed well for low PFAS levels:
Condoms
- Kimono Micro Thin Barely There Condoms
- P.S. Good Times Exceptionally Thin Latex Condoms
- Sustain Natural Ultra Thin Lubricated Latex Condoms
- Glyde Ultra Standard Fit Ultra Thin Condoms
- Durex Real Feel Non-Latex Regular Fit Polyisoprene Condoms
Lubricant
- Astroglide Water-Based Long Lasting Personal Lubricant
- KY Me & You Condoms Extra Lubricated
- Good Clean Love Almost Naked Personal Lubricant
- Aloe Cadabra Natural Aloe Personal Lubricant
- Honey Pot Organic Moisturising Lubricant
- Foria Awaken Arousal Oil with Organic Botanicals
When shopping for lubricants, choosing fragrance-free and paraben-free formulas in glass or non-leaching packaging can also reduce exposure to unnecessary chemicals and avoid plastics that can shed into products.
Feminine hygiene products
For period care, organic cotton pads and tampons keep things simple. They tend to contain fewer synthetic polymers, no mystery fragrances and less exposure to additives that can irritate sensitive vaginal tissue.
Reusable options are also worth considering. Try menstrual cups and PFAS-free leakproof underwear. Just be sure to follow cleaning instructions, replace as recommended, and skip anything that consistently causes irritation. For those thinking about sustainability, these reusable options can also help reduce microplastic waste over time.
Minimise microplastic exposure and protect your health
PFAS and microplastics aren't topics many of us expected to worry about when shopping for pads, condoms or lubricants. Yet, here we are.
Thankfully, awareness is a powerful form of self-protection. By choosing products that minimise the chemical burden on highly vascular genital tissue, you're supporting your hormone health, fertility and long-term wellbeing.
But you don't need to clean out your cabinets or overhaul your life overnight. Small shifts, like opting for organic cotton, PFAS-free condoms or fragrance-free lubricants, can meaningfully reduce your exposure to microplastics over time. And those small shifts matter, because your body deserves products that support it.
With a few intentional swaps, safer intimate care is absolutely within reach.

Frequently asked questions
Do all condoms and period products contain PFAS or microplastics?
No. Independent testing found detectable PFAS indicators in roughly 14% of condoms and lubricants tested, meaning most were PFAS-free. Many tampons and pads do, however, contain synthetic plastics; organic cotton and reusable options reduce this.
Can microplastics really affect fertility?
Researchers have detected micro- and nanoplastics in reproductive tissues, and PFAS are linked to hormone disruption and reduced fertility in both men and women. A single product won't derail fertility, but reducing chronic, everyday exposure is a sensible precaution.
What are the easiest lower-plastic swaps?
Organic cotton tampons and pads, menstrual cups, PFAS-free leakproof underwear, fragrance-free lubricants, and condoms from brands that test low for PFAS. Small, gradual swaps add up.
Does this matter after menopause?
Yes. Falling oestrogen can leave vaginal tissue thinner and more reactive, so synthetic, fragranced products may irritate more easily, and barrier protection still matters for STI prevention if you're sexually active.
