A Topic Our Community Keeps Bringing Up
Our community ask questions, shares experiences and sometimes tells us about unconventional uses for menstrual products.
One topic that keeps coming up is the use of a menstrual disc (or cup) after intercourse when trying to conceive. The idea is that inserting a disc shortly after sex may help retain semen closer to the cervix. This may potentially give sperm a better chance of reaching the egg.
We want to be clear from the outset: we are not medical professionals, and we are not recommending this practice. There is currently no large-scale clinical evidence proving that menstrual discs improve conception rates. However, we also know that many people in the trying-to-conceive (TTC) community are already exploring this. We believe it is better to have an honest, informed conversation than to stay silent.
Where Does the Idea of Menstrual Disc Conception Come From?
The concept is not new. People trying to conceive have long explored ways to maximise sperm's proximity to the cervix after sex. These methods range from lying down with hips elevated to using disposable menstrual discs (a.k.a. soft cups) or diaphragms.
The basic reasoning is anatomical. During ejaculation, semen gathers near the posterior vaginal fornix, leaving the external cervical opening partially submerged. Sperm then begin swimming almost immediately. A menstrual disc, which sits in the vaginal fornix just below the cervix, may help hold that fluid. This keeps it in close proximity to the cervical opening, essentially creating a small reservoir near the cervix.
Some people also combine this with lying still for 15–30 minutes after intercourse. Interestingly, one study on intrauterine insemination (IUI), which is not natural intercourse, found a higher pregnancy rate with 15 minutes of rest afterwards. This finding has not yet been replicated in further research.
It is important to note that sperm begin moving rapidly after ejaculation. They can survive in the female reproductive tract for up to five days. Whether a disc meaningfully changes outcomes beyond what the body already facilitates is simply unknown.
What the Research Actually Says
To our knowledge, there are no large, high-quality clinical trials showing that menstrual discs or cups raise pregnancy rates. Most published research in this area focuses on cervical caps used with donor sperm for intracervical insemination, a different and more controlled context. Those results were mixed, with some studies showing modest benefit and others showing none.
Menstrual discs are not the same as cervical caps. A cervical cap is designed and sized to seal directly over the cervix. A menstrual disc sits in the vaginal fornix and is not designed to form a seal over the cervical opening. Assuming a menstrual disc works like a cervical cap is a leap that the evidence doesn't currently support.
What we do have is many anecdotal accounts from the TTC community. Thousands of people say this helped them. Anecdotal evidence is not the same as clinical evidence, but it is also not nothing. It reflects real lived experience, even if we cannot yet draw firm conclusions from it.
How People Are Doing It
Based on what our community and online TTC forums describe, here is the general approach people take. Please discuss this with your doctor before trying it yourself.
- Have intercourse as normal. No changes before or during intercourse are needed.
- Insert the disc shortly afterwards — ideally within a few minutes. Many people do this while still lying down or with hips slightly elevated, before getting up. The goal is to position the disc to hold semen near the cervix before gravity takes effect. Ensure your hands are thoroughly washed before insertion.
- Rest lying down for 15–30 minutes. Some people use a thin pillow under the lower back or hips.
- Remove the disc carefully. Hook a finger under the front rim of the disc, angle it downward, and pull down and out slowly to avoid spilling the contents. Do this over a toilet or in the shower.
- Clean the disc properly. If using a reusable disc, wash it thoroughly with warm water and a mild, fragrance-free soap. If using a disposable disc, discard it.
Important Things to Be Aware Of
- This is not a medically endorsed method. No regulatory body or fertility organisation currently recommends menstrual discs as a conception aid.
- A menstrual disc is not a contraceptive. Menstrual discs do not block sperm, do not contain hormones and do not prevent pregnancy. They should never be relied upon to prevent conception.
- Hygiene matters. Inserting anything vaginally post-intercourse carries a small risk of introducing bacteria if hands or the disc are not clean. Always wash your hands and ensure the disc has been properly cleaned before use.
- Discs do not protect against STIs. Menstrual discs do not protect against sexually transmitted infections or diseases.
- If you are undergoing fertility treatment, speak to your specialist first. Do not add supplementary techniques to a clinical fertility plan without medical guidance.
- Stop use if you experience any adverse symptoms. If you notice fever, unusual discharge, pelvic pain or any other concerning symptoms, remove the disc and see your GP promptly.
Choosing a Disc
If you decide to explore this method, first ensure you are comfortable inserting and removing a menstrual disc. Fumbling with an unfamiliar product immediately after intercourse is not ideal.
Both reusable silicone discs and disposable discs can work for this purpose. Reusable medical-grade silicone discs are easy to clean and can be used many times. Disposable discs are convenient if you prefer a single-use option. The priority is fit and your comfort with the product.

Our Thoughts
We started Period Shop because we believe Australians deserve honest, open conversations about their bodies. We know the journey to conceive can be long, emotional and expensive. We also understand why people explore every avenue they can.
We are not going to tell you this method works, because the evidence is not there yet. We are also not going to dismiss what thousands of people in the TTC community report. They are trying it, talking about it and believe it has contributed to their success in conceiving. Our aim is to ensure that if people choose to try something, they have the clearest possible information. We also encourage them to talk to their doctor first.
We are cheering you on.
