If you're choosing between a menstrual cup, menstrual disc or menstrual sponge, start with how each product works and where it sits in your body. Cups and discs collect menstrual flow, while sponges absorb it. From there, your anatomy, flow, comfort, removal preferences, cleaning routine and whether you want a reusable or single-use option can help narrow down the choice.
There isn't one option that is best for everyone. The aim is to find a product whose design suits your body and the way you want to manage your period.

How do you choose between a menstrual cup, disc or sponge?
Before comparing individual brands or sizes, think about what you actually want from the product.
- Do you want a product that collects or absorbs menstrual flow? Cups and discs collect blood, while sponges absorb it.
- Where and how do you want the product to sit? Cups and sponges sit in the vaginal canal, while discs sit higher beneath the cervix.
- What does your flow require? Capacity can matter on heavier days, but good fit comes first.
- How do you feel about insertion and removal? Cups, discs and sponges each use a different technique.
- Do you want a reusable or single-use option? Cups are reusable, while discs and sponges can include both reusable and single-use products.
- Do you want a product you can wear during penetrative vaginal sex? Some discs and some single-use synthetic sponges are designed for this, while menstrual cups generally are not.
Once you have a sense of which design sounds most appealing, you can start comparing individual products within that category.
Menstrual cups
A menstrual cup is a flexible cup-shaped product that sits in the vaginal canal and collects menstrual flow. It is folded for insertion, then opens inside the vagina and forms a seal against the vaginal walls.
A cup may be worth considering if you want a reusable collecting product, are comfortable learning a folding and insertion technique and like having a wide choice of lengths, shapes and firmness levels.
What should you compare when choosing a cup?
Generic sizes such as “small” and “large” don't tell you enough about how a cup will fit. A better way to compare cups is:
- Cervix height and cup length
- Diameter and shape
- Firmness
- Capacity
- Removal design
For example, someone with a lower cervix may find a shorter cup more comfortable, while someone with a high cervix may prefer a longer cup that is easier to reach. Firmness can affect how easily a cup opens and how noticeable it feels, while shape and diameter can influence the seal and overall fit.
If you're not sure about your cervix height, our guide to measuring your cervical position is a useful starting point. You can then compare individual models in the Menstrual Cup Comparison Chart.
How long can you wear a menstrual cup?
Menstrual cups supplied in Australia must include instructions setting a maximum duration of use that does not exceed 12 hours. Your flow may mean you need to empty the cup much sooner, so think of the stated wear time as a maximum rather than a target.

Menstrual discs
A menstrual disc is a shallow, flexible collecting product that sits higher in the vagina than a cup. The back of the rim sits in the vaginal fornix, while the front is tucked behind the pubic bone.
A disc may appeal if you prefer a flatter collecting product, don't want a cup-style seal or want to consider a product that can be worn during penetrative vaginal sex.
What should you compare when choosing a disc?
Disc fit is mainly about how the product fits within the space available in your anatomy and whether the front rim can remain comfortably tucked behind the pubic bone.
Useful features to compare include:
- diameter
- shape
- rim firmness
- reservoir design and practical capacity
- removal features such as a notch, tab or loop
Cervix height can still be useful information, but a high or low cervix does not by itself tell you which disc diameter you need.
The Menstrual Disc Comparison Chart lets you compare individual products side by side.
Can you have sex with a menstrual disc?
Some menstrual discs are specifically designed to be worn during penetrative vaginal sex. Check the instructions for the individual disc rather than assuming every design is suitable.
A menstrual disc is not contraception and does not protect against sexually transmitted infections.
Menstrual sponges
Menstrual sponges are soft products that sit in the vaginal canal and absorb menstrual flow rather than collecting it.
The category includes different types of products. Some natural sea sponge products are sold for reuse, while some synthetic menstrual sponges are designed for single use. Their materials, intended use and care requirements can be quite different, so it is important to look at the individual product rather than treating all menstrual sponges as interchangeable.
A sponge may appeal if you prefer a soft absorbent internal product or want an alternative to a cup or disc.
What should you compare when choosing a sponge?
Look at:
- the material and construction
- whether it is reusable or single-use
- its intended use
- wear-time instructions
- how it should be cleaned, if reusable
- how often it should be replaced
The evidence and regulatory framework for menstrual sponges are less developed than they are for menstrual cups. Menstrual cups in Australia have a specific product standard, TGO 99, while menstrual sponge regulation has been the subject of ongoing discussion by the TGA's Women's Health Products Working Group, including opportunities for clearer product standards and improved oversight.
That does not mean every menstrual sponge should be treated the same way. It does mean that product-specific material, care and use information is particularly important when comparing them.
A product being described as “natural” does not by itself tell you whether it is safer or better suited to your body. Look at what the product is made from, how it is intended to be used and the care instructions supplied with it.

Which option may suit different priorities?
If you're still deciding between categories, this is a useful shortcut:
If you want a reusable collecting product
Look at a menstrual cup or reusable disc. The main difference is where they sit and how they stay in place, so compare fit and removal as well as capacity.
If you prefer a flatter product that sits higher
A menstrual disc may be worth exploring. Some people prefer the way a disc sits behind the pubic bone rather than in the vaginal canal like a cup.
If you want an absorbent internal product
A menstrual sponge is the absorbent option in this comparison. Check whether the particular sponge is reusable or single-use and follow its care and replacement instructions.
If you want an option for penetrative period sex
Some menstrual discs and some single-use synthetic menstrual sponges are designed to be worn during penetrative vaginal sex. Check the exact product instructions before using one this way.
If you're still not sure

Consider your flow, but don't choose by capacity alone
Capacity is a consideration, particularly if you have a heavier flow, but a higher-capacity product cannot make up for poor fit.
A cup or disc that fits well may be more useful than a larger product that causes pressure, leaks because it isn't positioned correctly or is difficult to remove.
Advertised capacity also isn't always the amount you can use in practice. Flexible discs, for example, can compress once they are inside the body, so their practical capacity may differ from the figure measured outside the body.
If your bleeding is unusually heavy, has changed noticeably or is interfering with everyday life, speak with a healthcare professional rather than relying only on a higher-capacity period product.
Think about comfort and pressure
Internal period products should feel comfortable once they are positioned correctly.
A firmer cup or disc rim may be easier for some people to position, while another person may find the same firmness too noticeable. Shape, diameter and positioning can also affect bladder or pelvic pressure.
A sponge feels very different again because it is soft and absorbent rather than structured.
If a product causes persistent pain or significant discomfort, don't assume you simply need to get used to it. Check the fit and positioning and consider whether another size, shape or product type may suit you better.
Don't forget about removal
People often spend a lot of time thinking about insertion and very little time thinking about how they will get the product back out. Removal design can make a real difference, particularly if you have a high cervix, reduced dexterity or simply prefer something easier to grip.
With a cup, you generally need to reach the base, release the seal and guide the cup out. The stem can help you locate the cup but should not usually be used to pull a sealed cup straight out.
With a disc, removal varies considerably between designs. Some use a plain rim, while others have a finger notch, tab or loop to make the product easier to reach.
With a sponge, you reach into the vaginal canal and remove the absorbent material directly.
Think about which technique feels most manageable before choosing purely on capacity or appearance.
Compare cleaning and care
Reusable cups, discs and sea sponge products all need appropriate care, but their cleaning methods are not necessarily the same.
Follow the instructions supplied with your product for:
- cleaning between uses
- sanitising or boiling, where applicable
- drying
- storage
- maximum wear time
- replacement
Single-use products should be discarded according to their instructions rather than washed and reused.
Frequently asked questions
Is a menstrual cup or disc easier to use?
Neither is easier for everyone. Cups involve folding, insertion, opening and releasing the seal for removal, while discs are pinched for insertion, positioned behind the pubic bone and removed using the rim or a removal feature. Some people find cup positioning more intuitive, while others prefer the narrow folded profile and flatter fit of a disc.
Which is better for a low cervix, a menstrual cup or disc?
A low cervix does not automatically mean you need a disc. Shorter menstrual cups can work well for some people with a low cervix, while disc fit depends on whether the disc's diameter and shape suit the space in your anatomy and remain securely tucked behind the pubic bone. Compare the dimensions and fit of individual products rather than choosing by category alone.
Which holds more, a menstrual cup or disc?
It depends on the individual products. Some cups and discs have relatively high stated capacities, but advertised capacity is not the only consideration and may not equal practical capacity once the product is inside the body. Fit should come before choosing whichever product has the largest number on the packaging.
Can you have sex with a cup, disc or sponge in?
Menstrual cups are generally not designed to be worn during penetrative vaginal sex. Some menstrual discs and some single-use synthetic menstrual sponges are specifically designed for this purpose, but suitability depends on the individual product. None of these products should be treated as contraception or protection against sexually transmitted infections unless the product is specifically approved for those purposes.
Are menstrual sponges reusable?
Some are and some are not. Natural sea sponge menstrual products may be sold as reusable products with specific cleaning and replacement instructions, while some synthetic menstrual sponges are designed for single use. Check the instructions for the exact product rather than assuming all menstrual sponges should be used in the same way.
So, which should you choose?
Choose by how the product fits your body and how you want to use it, rather than trying to find a single “best” period product.
A menstrual cup may appeal if you want a reusable collector that sits in the vaginal canal and offers plenty of choice in length, shape and firmness. A disc may suit you if you prefer a flatter collector that sits higher or want to consider a product designed for penetrative period sex. A sponge may appeal if you prefer a soft absorbent internal product.
Whichever category you're considering, look beyond broad labels and compare the individual product's dimensions, material, fit, removal method, care requirements and intended use.
