Menstrual sponges are soft internal period products that absorb menstrual flow rather than collecting it. They fall into two main categories: reusable natural sea sponges, which are washed and reused, and single-use synthetic sponges, which are discarded after use.
The best choice depends on your flow, comfort, removal preferences and how much cleaning you are comfortable with. Wear time, sizing and care instructions vary between products, so always follow the directions supplied with the particular sponge you use.
Reusable vs disposable menstrual sponges: what is the difference?
The main difference is what happens after you remove the sponge. A reusable sea sponge must be cleaned, thoroughly rinsed, dried and eventually replaced. A synthetic sponge is used once and placed in the rubbish after removal.
| Feature | Reusable natural sea sponge | Single-use synthetic sponge |
|---|---|---|
| Material | Harvested natural sea sponge | Manufactured polyurethane foam |
| Use | Washed and reused according to the brandโs care instructions | Used once and discarded |
| Shape and size | Naturally variable and may be trimmable | Consistent manufactured shape and dimensions |
| Removal aid | Usually none | Some products have a finger slit or grip feature |
| Cleaning | Must be cleaned, rinsed and completely dried as directed | No cleaning after use |
| Period sex | Do not assume suitability; check the product instructions | Some products are specifically marketed for penetrative period sex |
| Waste | Lower product waste because each sponge can be reused | Each sponge and its packaging are discarded after use |
No menstrual sponge is automatically the best option for everyone. Consider the complete product โ including its material, dimensions, removal design, care requirements and manufacturerโs wear-time instructions โ rather than choosing by size alone.

Product ranges and manufacturer instructions can change. Check the product page and the instructions supplied with your sponge before use.
Compare reusable natural sea sponges
Natural sea sponges vary in shape, texture and exact dimensions because they are not moulded products. They usually have no string or built-in removal feature, so you need to be comfortable reaching into the vaginal canal to remove them.
Natural Intimacy Menstrual Sea Sponges
Natural Intimacy Menstrual Sea Sponges are harvested from the Mediterranean Sea and made in Spain. They are available in bleached and unbleached options:
- Medium: approximately 55โ65 mm, supplied in a three-pack
- Large: approximately 65โ80 mm, supplied in a two-pack
Current product instructions state that the sponge should be removed and cleaned at least every eight hours and more frequently when required for heavier flow. The sponge may be carefully trimmed for comfort. Follow the supplied cleaning instructions and do not boil it, as boiling can make a natural sponge shrink and toughen.
Jade & Pearl Sea Pearls
Jade & Pearl offers two types of reusable menstrual sea sponge:
- Sea Pearls Classic, a denser and more durable natural sea sponge
- Sea Pearls Premium Ultra Soft, a softer Mediterranean sea sponge
Both are available in small, medium and large sizes, as well as a multi-size pack. Approximate dimensions are:
- Small: 38โ51 mm
- Medium: 51โ63 mm
- Large: 63โ76 mm or slightly larger because each sponge is naturally shaped
Current Period Shop instructions advise removal after three to four hours, or more frequently with heavier flow. Sea Pearls may be carefully trimmed around the edges, but should not be cut in half. Manufacturer guidance states that a properly cared-for sponge may be reusable for approximately three to six months, although its condition should determine when it is replaced.
Compare single-use synthetic menstrual sponges
Synthetic menstrual sponges are manufactured from polyurethane foam. Their dimensions and shape are more consistent than natural sponges and some include a finger slit to assist with removal. They are not reusable.
Beppy Menstrual Sponges
Beppy Menstrual Sponges are made in the Netherlands and come in two styles:
- Beppy Wet: approximately 60 ร 45 ร 25 mm, with a water-based gel coating and an integrated finger slit
- Beppy Classic Dry: approximately 52 ร 30 mm, without the gel coating or removal slit
Beppy states a maximum wear time of eight hours. Each sponge is for single use and must be discarded after removal.
Joy Division Soft-Tampons
Joy Division Soft-Tampons are single-use polyurethane foam sponges manufactured in Germany.
- Mini: approximately 45 ร 55 ร 20 mm, with an integrated finger slit
- Normal: approximately 50 ร 55 ร 24 mm, with an integrated finger slit
- Professional: approximately 50 ร 24 mm, with a round design and no removal aid
- Hot Lady: approximately 50 ร 24 mm, with a round design and no removal aid
Joy Division advises changing the sponge more frequently on heavier days and states a maximum wear time of eight hours. Its current instructions also advise against overnight wear.
Which menstrual sponge may suit you?
A reusable sea sponge may suit you if you:
- want a reusable internal period product
- are comfortable washing, thoroughly rinsing and drying it
- like the option of carefully trimming a sponge to adjust its shape
- have somewhere suitable to clean and dry it between uses
- are comfortable removing it without a string or built-in grip feature
The trade-off is that natural sea sponges require more care and vary from one sponge to another. The evidence about their safety is also limited, which is discussed below.
A single-use synthetic sponge may suit you if you:
- want to avoid cleaning and drying a reusable sponge
- prefer a consistent manufactured shape
- want individually packaged products for travel or occasional use
- want an option with a finger slit to assist removal
- want a product specifically designed for use during penetrative period sex
The trade-off is that each sponge is discarded after use and products without a removal aid may require more confidence with internal removal.
What size menstrual sponge should you choose?
There is no universal menstrual sponge sizing or absorbency system. A medium from one brand may not have the same dimensions, density or absorbency as a medium from another.
Consider:
- Your flow: a larger sponge contains more material, but this does not provide a standardised absorbency measurement
- Your comfort: the sponge should not cause pressure, pain or irritation
- Removal: you must be able to reach and securely grasp the sponge
- Product dimensions: compare actual measurements rather than relying only on small, medium or large labels
- Trimming: some natural sea sponges can be trimmed around the edges, but only if the manufacturer permits it
Choose according to your anatomy, flow and preferences rather than your age or whether you have given birth.
How long can you wear a menstrual sponge?
Wear-time instructions vary by brand:
- Jade & Pearl: remove after three to four hours or more frequently with heavier flow
- Natural Intimacy: remove and clean at least every eight hours and sooner when required
- Beppy: maximum eight hours
- Joy Division: change sooner on heavier days and do not exceed eight hours
Remove the sponge sooner if it becomes saturated, starts leaking, feels uncomfortable or you develop irritation. Do not exceed the instructions supplied with your product even if your flow is light.
Which menstrual sponge is easiest to remove?
A removal feature can make a sponge easier to locate and grip, but it does not pull the sponge out like a tampon string.
- Beppy Wet: integrated finger slit
- Beppy Classic Dry: no removal slit
- Joy Division Mini and Normal: integrated finger slit
- Joy Division Professional and Hot Lady: no removal aid
- Natural sea sponges: generally no built-in removal aid
To remove a sponge, wash your hands, relax and bear down gently to help bring it within reach. Grasp or pinch the sponge and bring it slowly towards the vaginal opening. Do not use sharp objects or tweezers. If you cannot remove it, it is painful to reach or removal attempts are causing injury, seek help from a healthcare professional.
Can menstrual sponges be worn during period sex?
Some synthetic sponges, including Beppy and Joy Division products, are marketed for use during sex. Their stringless design sits higher in the vaginal canal than a conventional tampon and usually can't be felt by a partner during penetration.
A menstrual sponge is not contraception and does not protect against sexually transmitted infections. Only use a sponge during sex if its instructions specifically permit this and follow the manufacturerโs directions about removal and replacement afterwards.
Which menstrual sponge is easier to clean?
Single-use synthetic sponges require no cleaning because they must be discarded after use. Never wash and reuse a product labelled as single-use.
Reusable sea sponges require careful cleaning, thorough rinsing and complete drying before storage. Cleaning directions differ between brands. Some manufacturers recommend mild soap or a short soak using a specified solution and advise against boiling, harsh chemicals or soaking for longer than directed.
Follow the instructions for your particular sponge rather than applying a generic menstrual cup or tampon cleaning method. Inspect it regularly and replace it if it develops a persistent odour, begins to break down or cannot be cleaned as directed.
Are menstrual sponges safe?
The evidence base for menstrual sponges is limited, particularly when compared with better-studied menstrual products. Much of the published research and regulatory information relates to natural sea sponges sold several decades ago, so it cannot measure the risk of every current product.
A 1982 study comparing 25 sea sponge users with 58 tampon users found significantly higher menstrual colonisation rates of Staphylococcus aureus, Escherichia coli and other Enterobacteriaceae among the sea sponge users. Historical testing reported by the US Food and Drug Administration also found sand, grit, bacteria, yeast and mould in sampled natural sponges. One sample contained Staphylococcus aureus, and the FDA reported one case of toxic shock syndrome associated with sea sponge use and another possible case.
These historical findings do not establish the level of risk associated with a particular sponge sold today and do not directly evaluate current single-use synthetic sponge products. They do mean that menstrual sponges should not be described as risk-free or inherently safer than other internal period products.
What about toxic shock syndrome?
Toxic shock syndrome (TSS) is very rare but can be life-threatening. Possible symptoms include a sudden high temperature, vomiting, diarrhoea, dizziness, confusion, aching muscles and a red rash that may resemble sunburn.
If you develop symptoms that could indicate TSS while using a menstrual sponge, remove it and seek urgent medical care. In Australia, call 000 or go to the nearest emergency department if you think you may have TSS.
To use a menstrual sponge more safely:
- wash and dry your hands before insertion and removal
- follow the productโs maximum wear time and remove it sooner when necessary
- never reuse a single-use synthetic sponge
- clean, rinse, dry and store a reusable sponge exactly as directed
- do not use a sponge that is damaged, deteriorating or has a persistent unpleasant odour
- stop using it if it causes pain, irritation or unusual symptoms
Speak with a healthcare professional before using an internal menstrual product if you have previously experienced TSS or have been advised to avoid vaginal products. After childbirth, miscarriage or a gynaecological procedure, wait until your healthcare professional says internal products can be used again.
What is the Australian regulatory position on menstrual sponges?
In March 2026, the Therapeutic Goods Administrationโs Womenโs Health Products Working Group discussed concerns about the current access framework and regulation of menstrual sponges. The discussion included opportunities for clearer product standards and improved oversight.
This indicates that menstrual sponge regulation is under consideration in Australia. It was not a finding that every menstrual sponge currently sold in Australia is unsafe, nor was it an endorsement of any individual product.
Frequently asked questions
Are all menstrual sponges reusable?
No. Natural sea sponges may be reusable when the product is specifically sold and labelled for reuse. Synthetic sponges such as Beppy and Joy Division are single-use products and must be discarded after removal.
Can a menstrual sponge get lost?
A sponge cannot travel through the cervix into the uterus, but it can move higher in the vaginal canal and become difficult to reach. Relax, squat or sit on the toilet and bear down gently. Seek medical help if you cannot remove it or removal is painful.
Can you sleep with a menstrual sponge?
Check the instructions for your particular product. Never exceed its stated wear time. Joy Division currently advises against overnight wear, while other products specify maximum wear times that may not cover a full nightโs sleep.
Do menstrual sponges have standard absorbency ratings?
No. Unlike conventional tampons, there is no universal absorbency classification across menstrual sponge brands. Size and density may provide some guidance, but they are not standardised measurements of how much menstrual fluid a sponge will hold.
The bottom line
Reusable sea sponges and single-use synthetic sponges offer different advantages. Natural sea sponges reduce product waste and can be shaped for an individual fit, but require careful cleaning and have a limited evidence base. Synthetic sponges offer consistent shapes, individual packaging and optional removal features, but create more waste and cannot be reused.
Compare actual dimensions, wear time, removal design and care requirements rather than relying on a generic size label. Most importantly, follow the instructions supplied with your sponge and stop using it if it causes pain or unusual symptoms.
