Menstrual cups have become increasingly popular as an alternative to traditional menstrual products like pads and tampons. These bell-shaped devices, typically made from medical-grade silicone, rubber, or elastomer, are inserted into the vagina to collect menstrual fluid. While they offer several benefits, such as being environmentally friendly and cost-effective, concerns have been raised about their safety, particularly regarding their potential impact on fertility. This article explores whether menstrual cups can cause infertility, examining scientific evidence and expert opinions on the subject.
Understanding Menstrual Cups
What are Menstrual Cups?
Menstrual cups are reusable devices designed to collect menstrual blood. They come in various sizes and shapes to accommodate different anatomical needs and menstrual flow rates. Users typically insert the cup into the vagina, where it forms a seal against the vaginal walls. The cup can be worn for up to 12 hours before it needs to be removed, emptied, cleaned, and reinserted.
Benefits of Menstrual Cups
Cost-Effective: Menstrual cups can be used for several years, making them a cost-effective option compared to disposable pads and tampons.
Environmentally Friendly: Since they are reusable, menstrual cups significantly reduce the amount of menstrual product waste.
Convenience: With a longer wear time, menstrual cups offer more convenience, especially for women with busy lifestyles.
Health Benefits: Menstrual cups do not contain the chemicals often found in tampons and pads, which can be beneficial for women with sensitive skin or allergies.
Concerns About Menstrual Cups and Infertility
What is Infertility?
Infertility is defined as the inability to conceive after one year of regular, unprotected intercourse. It can result from various factors affecting either the male or female reproductive systems. In women, infertility can be due to issues with ovulation, fallopian tubes, or the uterus. Concerns about menstrual cups typically focus on their potential to cause infections or trauma that could lead to infertility.
Potential Risks Associated with Menstrual Cups
Infections: One of the primary concerns is that menstrual cups could introduce or exacerbate infections, such as bacterial vaginosis or yeast infections, which, if untreated, could affect fertility.
Toxic Shock Syndrome (TSS): Although rare, there have been reports of TSS associated with menstrual cup use. TSS is a serious condition caused by bacterial toxins.
Physical Trauma: Incorrect use of a menstrual cup could potentially cause trauma to the vaginal walls or cervix, which might impact fertility.
Scientific Evidence on Menstrual Cups and Infertility
Infection Risk
Several studies have investigated the safety of menstrual cups. A systematic review published in The Lancet Public Health in 2019 analyzed 43 studies involving over 3,300 women and girls. The review found that menstrual cups were as safe as other menstrual products and did not increase the risk of infections. Another study published in the Journal of Women’s Health in 2020 confirmed these findings, noting that the risk of bacterial vaginosis and other infections was not higher in menstrual cup users compared to those using tampons or pads.
Toxic Shock Syndrome
The association between menstrual cups and TSS is not well-documented. The risk of TSS with menstrual cup use appears to be lower than with tampon use, likely due to differences in how the products interact with the vaginal environment. The cases of TSS related to menstrual cups are exceedingly rare, and proper hygiene practices, such as regular cleaning of the cup, can further minimize this risk.
Physical Trauma
There is limited evidence to suggest that menstrual cups cause physical trauma leading to infertility. Most reported cases of trauma are related to improper use or failure to follow instructions. Ensuring that users are educated about proper insertion, removal, and maintenance can mitigate these risks.
Expert Opinions on Menstrual Cups and Infertility
Gynecological Perspectives
Many gynecologists support the use of menstrual cups and do not consider them a significant risk factor for infertility. Dr. Jen Gunter, a prominent gynecologist and author, has stated that there is no credible evidence linking menstrual cup use to infertility. She emphasizes the importance of proper use and hygiene but reassures patients that menstrual cups are generally safe.
Public Health Organizations
Public health organizations, including the World Health Organization (WHO) and various national health bodies, have reviewed the safety of menstrual cups. They generally endorse their use, highlighting that they are a safe and effective option for menstrual management. These organizations advocate for better education and access to menstrual cups to promote menstrual health and hygiene.
Proper Use and Maintenance of Menstrual Cups
Hygiene Practices
Maintaining proper hygiene is crucial for preventing infections and ensuring the safe use of menstrual cups. Users should wash their hands before inserting or removing the cup. The cup should be emptied and washed with mild soap and water at least twice a day. It is also important to sterilize the cup between menstrual cycles by boiling it for a few minutes.
Insertion and Removal Techniques
To avoid trauma, users should follow the manufacturer’s instructions for insertion and removal. This typically involves folding the cup in a specific way, inserting it at an angle, and ensuring it opens fully to form a seal. Removing the cup should be done gently by pinching the base to release the seal and pulling it out slowly.
Monitoring for Issues
Users should monitor for any signs of infection or discomfort. Symptoms such as unusual discharge, persistent pain, or a foul odor should prompt a visit to a healthcare provider. It is also advisable to replace the menstrual cup if it shows signs of wear or damage.

Comparing Menstrual Cups to Other Menstrual Products
Tampons and Pads
Tampons and pads are the most common menstrual products. Tampons are inserted into the vagina to absorb menstrual blood, while pads are worn externally. Both products have been associated with risks, such as TSS (more common with tampons) and skin irritation (common with pads).
Menstrual Discs
Menstrual discs are similar to menstrual cups but sit higher in the vaginal canal, near the cervix. They offer similar benefits and risks as menstrual cups but may be more comfortable for some users.
Period Panties and Reusable Pads
Period panties and reusable pads are external options that absorb menstrual blood. They are generally considered safe and may be suitable for individuals who prefer not to use internal products.
Addressing Misconceptions About Menstrual Cups
Misconception 1: Menstrual Cups Are Unhygienic
Some believe menstrual cups are unhygienic, but with proper cleaning and maintenance, they are as hygienic as other menstrual products. The key is to follow recommended hygiene practices diligently.
Misconception 2: Menstrual Cups Cause Pain and Discomfort
While some users may experience initial discomfort, this is often due to incorrect insertion or removal. Most users find menstrual cups comfortable once they become accustomed to using them correctly.
Misconception 3: Menstrual Cups Are Only for Certain Women
Menstrual cups come in various sizes and styles, making them suitable for most women, including those who have not given birth, those who have given birth, and those with different vaginal and cervical anatomies.
Conclusion
The current scientific evidence does not support the claim that menstrual cups cause infertility. When used correctly and maintained properly, menstrual cups are a safe and effective option for menstrual management. They do not increase the risk of infections or other conditions that could impact fertility. However, it is essential for users to practice good hygiene, follow instructions for use, and monitor for any signs of complications.
Healthcare providers should continue to educate patients about the proper use of menstrual cups and reassure them about their safety. By addressing concerns and providing accurate information, we can help more women make informed choices about their menstrual health.
