Easy Guide to Menstrual Cups: How to Use, Choose, and Their Benefits

Menstrual cups are gaining attention as an economical and reassuring option for long-term use. However, many people worry about things like, "Is it hard to insert?", "What about size and sterilization?" This article provides a neutral and easy-to-understand summary of what menstrual cups are, their pros and cons, correct usage and selection, and how to deal with common problems. We also offer tips for those who find their periods particularly difficult.

What is a Menstrual Cup? Differences from Pads and Tampons

A menstrual cup is a soft, small cup made of medical-grade silicone or similar material that is inserted into the vagina to "collect and hold" menstrual blood rather than "absorb" it. A major feature is that it can be washed and reused, with many lasting several years if properly cared for.

While pads and tampons are disposable and absorb menstrual blood, menstrual cups involve emptying the collected blood, washing the cup, and then reusing it. Let's first summarize the differences from other menstrual products in a table.

No single product is superior; it's best to choose based on your lifestyle, menstrual flow, and skin compatibility.

Pros and Cons of Menstrual Cups

Many people want to know the benefits of menstrual cups, but understanding the disadvantages and precautions is also important for confident use.

Main Benefits

• Long-lasting: With a larger capacity, they offer relative peace of mind during the day or sleep when frequent changes are difficult (still change every 8-12 hours at most).
• Economical: Being reusable, they can help reduce the ongoing cost of disposable products.
• Environmentally Friendly: They produce less waste, contributing to reduced environmental impact.
• Less Stuffiness/Rash: Menstrual blood is less likely to come into contact with the skin, making them suitable for those prone to rashes from pads.

Main Disadvantages/Precautions

• Requires practice to learn insertion and removal, which can be initially confusing.
• Requires washing and sterilization, and can be inconvenient in public restrooms.
• May leak if not inserted correctly.
• Rare risk of Toxic Shock Syndrome (TSS), requiring strict hygiene.

Disadvantages of Menstrual Cups, and Who They Are For/Who Should Consider Carefully

While menstrual cups offer many benefits, they also have disadvantages and may not be suitable for everyone. Here, we neutrally organize points to consider before purchasing. Understanding the disadvantages can help you calmly decide if they are right for you.

Disadvantages to Re-emphasize

• Takes time to get used to: It may take several menstrual cycles to master the technique of insertion and removal.
Inconvenience when out: In restrooms without a sink inside the stall, you'll need to figure out how to clean the cup after emptying. Carrying wet wipes or a bottle of water can be helpful.
• Initial cost: The price per cup is higher than disposable products, but because it's reusable, it tends to be more cost-effective in the long run.
• May be difficult to use depending on body type/condition: May not be suitable depending on the condition of the vagina or pelvic floor, or overall health.

Who They Are Often Suitable For / Who Should Consider Carefully or Consult a Professional

Even if you fall into the "should consider carefully" category, it doesn't mean you can't use it. If you're unsure whether it's right for you, consulting a medical institution, such as a gynecologist, can help you make a decision with peace of mind.

Correct Menstrual Cup Usage (Insertion, Removal, Sterilization)

The basics of menstrual cup use are "cleanliness" and "not rushing." Let's review the steps.

Insertion

1. Wash your hands thoroughly with soap.
2. Fold the rim of the cup (C-fold or punch-down fold are common).
3. In a relaxed position, slowly insert the folded cup into the vagina.
4. Inside, gently rotate it or press the base with your finger to ensure it has opened and sealed.

Removal

1. Wash your hands and bear down to grasp the base of the cup with your fingers.
2. Gently squeeze the base of the cup to release the suction, then slowly pull it out.
3. Empty the menstrual blood, wash the cup with water or lukewarm water, and reinsert.

Sterilization/Boiling

During use, rinsing with water is sufficient, but sterilization is important at the beginning and end of each period. For most products, it is recommended to boil the cup for several minutes (follow product instructions) in a pot of plenty of water. Be careful not to burn it by ensuring sufficient water, and using a dedicated sterilizing container can be convenient. Store in a clean, breathable pouch provided with the cup. Always check the instruction manual for your specific product.

How to Choose a Menstrual Cup (Size and Firmness Guide)

When choosing a menstrual cup, use the following points as a guide. However, these are general tendencies, and individual body conditions vary.

• Size: Many products use age and childbirth experience as a guide; generally, "smaller for younger individuals or those who haven't given birth," and "larger for those with childbirth experience or heavier flow" are common guidelines.
• Firmness (including stem): Softer cups cause less irritation upon insertion, while firmer ones tend to open more easily inside and are less prone to leaks.
• Capacity: If you are concerned about heavy flow days, a larger capacity type will provide more peace of mind.

For first-time users, it is often easier to start with a small to medium firmness. The appropriate size may also vary depending on the position of your pelvic floor (vaginal length), so if you feel it's not a good fit, consider a different size.

Can Menstrual Cups Be Used in Hot Springs and Pools? Etiquette and Precautions to Know

Many people consider using menstrual cups when their period coincides with a trip to a hot spring or when they want to swim. Menstrual cups are generally considered suitable for use in water because they collect menstrual blood inside the body, preventing leakage. However, there are a few points to be aware of when using them.

Considerations when using hot springs/public baths

• Pre-bath consideration: While menstrual cups collect menstrual blood inside the vagina, basic considerations remain the same: wash your body before entering the bath, and follow the rules and etiquette of each facility regarding bathing during menstruation. Facilities may have different policies, so check posted signs or guidance.
• Changing before and after bathing: It is most hygienic to insert a freshly cleaned cup before bathing and remove and wash it immediately after. If you are concerned about privacy in a public bath, it's safer to insert the cup at home or in a private changing area beforehand.
• Caution on heavy flow days: On days with heavy flow, it's important to consider refraining from bathing if it feels too risky.

Precautions when using in pools/the ocean

• Insert beforehand: Since it can be difficult to ensure clean hands in changing rooms, it's easier to insert the cup at home before heading out if possible.
• Water quality and hygiene: While the advantage is that menstrual blood is less likely to leak in water, remove and clean the cup as soon as possible after getting out. Follow product instructions for sterilization timing and methods.
• Avoid prolonged continuous use: Even during leisure activities, avoid continuous use for more than 8-12 hours and change the cup frequently.

Note that the fit and feel of menstrual cups in water vary from person to person. If you're using a menstrual cup in a hot spring or pool for the first time, try inserting it at home beforehand to get a feel for it and check for leaks, which will help you feel more confident on the day.

Common Problems and Solutions

• Leaks: Often caused by the cup not fully opening, being misplaced, or overflowing. After insertion, check the base to ensure it's open, and change more frequently on heavy flow days.
• Difficulty removing: Rushing can cause vaginal muscles to clench, making removal difficult. Take a deep breath and relax, then bear down and gently press the base to release the suction. Do not pull forcibly.
• Discomfort/Pain: Could be due to the cup being too high or too low, or the wrong size. Discontinue use if pain persists.

Hints for When It Hurts or Leaks: Causes and Solutions

Common concerns among new menstrual cup users are "pain" and "leaks." In most cases, these issues can be resolved by adjusting the size or insertion method. Here, we'll explain the causes and adjustment points for each problem. This is general information; if symptoms persist, do not self-diagnose and consult a medical professional.

When a Menstrual Cup Causes "Pain"

If you experience persistent pain or strong discomfort while wearing the cup, or if pain remains after removal, discontinue use. If pain recurs or lasts, there might be underlying factors beyond body type or size issues, so consult a gynecologist or other medical professional.

When a Menstrual Cup "Leaks"

Most leaks are caused by the cup not fully opening inside the vagina. A folded cup should open, either naturally or with the help of a finger, and seal tightly against the vaginal wall to collect menstrual blood. Check the following steps:

• Check for opening: After insertion, run your finger around the base of the cup to check for any dents or folds.
• Check for seal: Gently pinch the base of the cup and pull slightly; if there's resistance (a sucking sensation), it's sealed.
• Adjust position: If it's too high, it might not seal well. Recheck if it's positioned to cup the cervix.
• Overflow: On heavy flow days, the cup might fill up and leak. Shorten the time between changes or consider a larger capacity type.

If leaks persist despite correct insertion, or if you feel your menstrual flow is unusually heavy, consider consulting a medical professional (gynecologist) to assess your overall menstrual health.

TSS and When to Seek Medical Attention

Though rare, it's important to be aware of Toxic Shock Syndrome (TSS), a serious illness, when using menstrual cups or tampons. To prevent it, avoid prolonged use, handle with clean hands, and follow sterilization guidelines.

As a guideline for seeking medical attention, if you experience any of the following symptoms, stop using the cup and seek medical attention promptly:

• Persistent severe lower abdominal pain that is unusual for you
• Heavy bleeding that overflows your pad
• Sudden high fever, rash, vomiting, diarrhea, dizziness, or other symptoms suggestive of TSS

Especially with a high fever or a sunburn-like rash accompanied by feeling unwell, it's crucial to seek medical attention without hesitation.

The Background of "Menstrual Cup Death" Searches and TSS (Toxic Shock Syndrome)

The phrase "menstrual cup death" appearing in searches stems from concerns about Toxic Shock Syndrome (TSS), which can occur with the use of menstrual products. TSS is an acute systemic illness caused by toxins produced by bacteria; though rare, it can be life-threatening if severe. However, this is not unique to menstrual cups; it's a general precaution for all menstrual products used internally, like tampons. If used with proper knowledge, there's no need for excessive fear.

What's important is not to be "overly scared," but to "understand the potential risks and prevent them correctly." Below are basic principles to ease anxiety and ensure safe use:

Basics for Preventing TSS

• Do not leave it in for too long: If menstrual blood remains in the cup for an extended period, it creates an environment conducive to bacterial growth. Follow product instructions for continuous use; as a guideline, remove and wash the cup within 8-12 hours at most.
• Handle with clean hands: Always wash your hands thoroughly with soap before inserting or removing the cup. Keep your fingernails trimmed short to avoid scratching the cup or your vagina.
Follow product instructions for sterilization: The methods and duration for washing and boiling vary by product. Do not rely on self-made methods; always follow the instructions provided with your specific product.
• Avoid use when feeling unwell: If you have a fever or are generally feeling unwell, it's an option to switch to pads or other methods rather than forcing yourself to use the cup.

TSS is a very rare illness, but if you suddenly develop a high fever, a rash (like a sunburn), vomiting or diarrhea, dizziness, or severe malaise all at once, immediately remove the cup, discontinue use, and seek medical attention promptly. You don't need to determine "if it's TSS" yourself. If you have any concerning symptoms, it's important to consult a gynecologist or other medical professional near you.
