Introduction

Approximately 113,000 tonnes of menstrual waste accumulate every year in landfills in India. This menstrual waste comprises plastic, which takes many years to decompose, and harmful chemicals (bleach and dioxin) that are detrimental to the environment. Although menstrual cups have been around since the 1930s, they have found a big consumer market only since the 2000s. In India, only 1% of women use menstrual cups, primarily because of a lack of information, social taboos and certain myths.

Menstrual cups are a sustainable, healthy and safe alternative to tampons and sanitary pads. This article aims to provide an accurate account of menstrual cups underscoring their advantages and safety concerns to reduce the apprehension of women and ease the transition from tampons and pads to menstrual cups.

What is a menstrual cup?

A menstrual cup is a small bell-shaped feminine hygiene product made of medical-grade rubber, latex or silicone. Unlike a tampon or a pad that absorbs your period flow, a menstrual cup is inserted into the vagina to collect the menstrual flow.

How to use a menstrual cup?

If you are using it for the first time, start with a small size. Remove the cup from the packaging, wash it with soap and water and dry it before use. Before inserting the cup, wash your hands with soap and water. Wet the cup rim or apply a water-based lubricant to insert it easily into the vagina. Fold the menstrual cup tightly with the rim on top using one of the following methods:

  • The C fold: Flatten the cup and fold it into half; the rim will look like a C. This method places the cup very easily into the vagina.
  • Punch-down fold: Use the index finger to hold down one side of the cup to create a small entry point This method keeps the fold in place as the cup is inserted into the vagina.
  • The 7 fold: The rim is bent to form the shape of the number seven to create a small entry point.

According to gynaecologists, insert the cup into the vagina in a squatting position, sitting on the commode or lifting one leg. The folded cup is inserted towards the tailbone at an angle of 45°C. Once the cup is inserted, it opens up and rests against the vaginal wall and seals it to prevent any leakage. The period flow is collected in the cup. If you feel uncomfortable or the cup has not opened properly, try to rotate the cup. When a menstrual cup is used correctly, you do not even feel it is there.

Removing the menstrual cup

Wash your hands with soap and water. While in a sitting or squatting position, insert your thumb and index finger into the vagina to feel the stem of the cup. Do not pull the stem. A little further you will feel the cup base. Just pinch it to break the seal and remove it. If it does not come out using this method, use the pelvic floor muscles to push the cup down and remove it with the technique described above. Keep the cup upright to avoid spills and empty the contents into the toilet. Wash it with soap and water before reusing it.

Cleaning and storage of menstrual cups

Every time you empty the cup, rinse it with soap and water before reuse. Some companies provide special cleaning solutions. You must read the instructions to ensure you are cleaning the cup properly. After your period ends, you must wash the cup and sterilise it in boiling water. Usually, cups come with a reusable cloth bag or pouch for storage; otherwise, you may use a container to keep it clean and dry before the next cycle.

Types of menstrual cups

Menstrual cups can be stemmed or unstemmed. Stemmed cups have a stem that protrudes into the vagina. It is easy to remove these cups. Some women prefer unstemmed cups as the stems can make them uncomfortable and the stem may require trimming.

Size

Menstrual cups come in two sizes:

  • Small: Women who have not had a baby, are <30 years old and experience light to moderate flow
  • Large: Women who have had a baby, are >30 years old and experience heavy flow.

Teenagers should use the smallest size available.

Material

Menstrual cups are usually made of medical-grade silicone, latex or rubber. If you are allergic to latex, use silicone or rubber cups.

Shape

  • V shape: This is the most common design, with the length being more than the width. The cup gradually tapers from the rim.
  • Bell shape: The length is more than the width. It is rounder than the V-shaped cup as it flares out from the rim.
  • Round: The width is more than the length, and its widest point is below the rim.
  • Asymmetrical: The edge of the cup is slanted, and it has to be placed at a particular angle. The length is more than its width.

Benefits of menstrual cups

  • Menstrual cups are eco-friendly as they can be used for many years (2-10 years), reducing the waste in landfills.
  • Their one-time cost is more, but they are cost-effective in the long run. Menstrual cups cost between 500-2000 Indian rupees but when maintained properly, they can be re-used for many years. Sanitary pads incur a minimum cost of 150-200 Indian rupees per month.
  • Pads and tampons must be changed every 4-8 hours; menstrual cups can be used for 12 hours at a stretch and are good for overnight protection. Unlike menstrual cups, which cannot be felt if inserted correctly, pads can cause rashes, leave a moist sensation and feel bulky.
  • You can insert the cup around the time you expect your period, preventing leaks.
  • It can hold up to 10-40 mL of fluid, twice more than a super-absorbent pad/tampon. It is useful on the days the flow is heavy.
  • As cups form an airtight seal, you do not experience menstrual blood odour as the blood does not come in contact with air.
  • They do not cause vaginal dryness, unlike tampons.
  • The risk of toxic shock syndrome (TSS) is lower compared to tampons when used properly

Disadvantages of menstrual cups

  • Finding the right fit can be a challenge, particularly, if you have a low cervix or tilted uterus. Trial and error are required to find the right size, and you may experience leaks during this time.
  • Cup removal can be messy, particularly if you have to do it in a public restroom. Adequate clean water is required to clean the cup. You could carry a bottle of water to rinse the cup and wipe it with toilet paper before you insert it back.
  • Menstrual cups are not recommended if you have an intrauterine device (IUD, a birth control method) placed as the IUD could get dislodged.
  • If women are allergic to the cup material (silicone, rubber or latex), they should avoid using it or use cups made of another material.
  • If you have recently given birth or had any vaginal surgery, you should not use menstrual cups for at least 6 weeks and consult your gynaecologist before resuming their use.
  • Women who have vaginismus, a condition of involuntary vagina tensing, can cause pain while inserting the cup. Women should avoid using it if it causes discomfort.
  • There could be a slight risk of infection if the cups are not properly cleaned before use. Clean water is needed for washing the cups, which could be a problem if you are camping or hiking.
  • Unclean cups or cups inserted without a lubricant can irritate the vagina.
  • New users may find it challenging to insert, remove and adjust the cup.

Importance of educating women on menstrual cups

Many women in India are unaware of menstrual cups or how to use them. This lack of knowledge coupled with fear of inserting the cup into the vagina, lack of access and availability in pharmacies and local markets and scarcity of hygienic places for cleaning the cups are potential hurdles in adopting menstrual cups.

Women also fear being judged by peers for using menstrual cups, which further discourages them. There is a myth that once the cup is inserted into the vagina, it will get lost, which is incorrect. Women also believe that using menstrual cups will loosen and widen the vagina, which is untrue because the vagina is elastic and retains its natural shape after the cup is removed.

Even gynaecologists lack sufficient knowledge of menstrual cups. This deters women from using it as they have no one to guide them. Women need emotional support during initial menstrual cup usage.

Accurate information on the different types of cups, their available sizes and shapes and the guidance on sterilisation and storage must be made available so that women can choose the right fit for themselves.

Women should be educated that using menstrual cups involves a learning curve, where there is a possibility of feeling discomfort in the beginning. Providing realistic information and proper advertisement prepares women to make informed choices about the product. Accurate information also helps governments and NGOs who undertake initiatives to provide menstrual cups free or at reduced prices to make them affordable.
