Can a Menstrual Disc Help You Conceive? What the Evidence and TTC Community Say

Menstrual disc shown as a period-care product for people considering its use while trying to conceive

People in the trying-to-conceive (TTC) community sometimes describe inserting a menstrual disc after sex to keep semen close to the cervix. This is sometimes called the “Softcup method” online, after the Softcup brand of menstrual disc. However, people now describe using various disposable and reusable menstrual discs in a similar way. The idea has circulated through fertility forums, social media groups and personal success stories for years.

Some people report becoming pregnant during a cycle when they tried it and believe the disc helped. Others use a disc because it reduces post-sex leakage or gives them a greater sense of control during a process that can feel uncertain.

The honest answer is that there is no good clinical research showing that using a menstrual disc after sex increases the chance of pregnancy. That means the method is unproven. It does not mean researchers have demonstrated that it cannot work.

This article looks at what people in the TTC community report, what the research can and cannot tell us and what to consider if you decide to try the method.

Please note: This article provides general information and is not a substitute for personalised medical advice. A menstrual disc is not a fertility treatment. If you are using donor sperm, undergoing fertility treatment or have concerns about your fertility, speak with your GP, fertility specialist or another qualified healthcare professional.

At a Glance

  • Some people in TTC communities insert a menstrual disc after sex, a practice sometimes called the Softcup or menstrual disc method.
  • People report pregnancy success stories, less semen leakage and a greater sense of agency, but these experiences cannot show whether the disc caused a pregnancy.
  • No good-quality clinical trials have tested whether using a menstrual disc after intercourse improves conception rates.
  • Sperm begin moving through the cervix quickly and semen leaking out after sex is normal.
  • If you choose to try it, use a clean, comfortable disc, follow the product’s normal instructions and do not let it delay fertility advice when you need it.

What Is the Softcup or Menstrual Disc Method?

The Softcup method is an informal term used online for inserting a menstrual disc after vaginal sex when trying to conceive. The name comes from the Softcup brand of disposable menstrual disc, but people now use it more broadly when discussing similar practices involving disposable or reusable menstrual discs.

A menstrual disc sits high in the vaginal fornix, with the back rim positioned behind the cervix and the front rim tucked above or behind the pubic bone. Because it sits beneath the cervix, some people believe it may hold semen in that area for longer or reduce the amount that flows out of the vagina.

This is a community-developed practice rather than a recognised medical fertility technique. There is no standard protocol, proven insertion time or evidence-based wear period for conception.

If you have not used a disc before, our guide to using a menstrual disc explains its normal positioning, insertion and removal. Our guide to reproductive anatomy can also help you understand where the cervix sits.

What Are People in the TTC Community Reporting?

Customer conversations and online TTC forums contain recurring accounts of people trying a menstrual disc after sex. These experiences tend to fall into three groups.

Pregnancy success stories

Some people say they conceived during the first cycle they used a disc. Others say they tried it after several unsuccessful cycles and later became pregnant. These stories can feel compelling, especially when the person had been trying for some time.

However, becoming pregnant during the same cycle as using a disc does not establish that the disc caused it. Without a comparison group, we cannot separate any possible effect of the disc from fertile-window timing, ordinary cycle-to-cycle chance or other changes made that month.

Online reports are also affected by selection and reporting bias. People with a memorable success may be more likely to post than people for whom nothing changed.

Less leakage after sex

Many people describe using a disc because it contains some of the fluid that would otherwise leak out after intercourse. This can be a genuine practical benefit, even if it does not improve conception. Less leakage may make it easier to get up, sleep or continue with the day.

It is also important to know that leakage is normal. Fluid coming out does not mean that all the sperm have been lost or that you have reduced your chance of pregnancy.

A greater sense of agency

Trying to conceive can involve a lot of waiting and uncertainty. Some people say that using a disc helps them feel they have done something active after intercourse.

That emotional benefit is valid, provided the practice does not become another source of pressure or create the belief that pregnancy depends on doing it perfectly.

You may also see people discuss placing semen directly into a disc before inserting it. That is a form of home insemination and is different from inserting a menstrual disc after intercourse. It raises separate questions about semen collection, donor screening, storage, timing and infection risk.

This article does not provide a home insemination protocol. If you are considering donor sperm or assisted conception, seek advice from a fertility professional or appropriately regulated clinic.

What Does the Research Actually Say?

There is very little clinical research on menstrual discs or menstrual cups as conception aids. We could not identify a good-quality trial comparing pregnancy rates among people who inserted a menstrual disc after intercourse with people who did not.

That leaves us with an important middle ground:

  • Research has not shown that menstrual discs improve the chance of conception.
  • Research has also not directly tested this exact practice and proved that it makes no difference.
  • Pregnancy stories are anecdotal evidence. They can identify a practice worth discussing, but they cannot measure how effective it is.

Some older studies investigated cervical caps or reservoirs used for donor insemination. A 1996 randomised trial found no advantage from one cervical-cap method over standard intracervical insemination, while a 1997 trial reported a higher pregnancy rate with a different cap technique.

These studies are not evidence for the menstrual disc method. A cervical insemination cap is a purpose-designed device used with a semen sample at or over the cervix. A menstrual disc is a period-care product that sits in the vaginal fornix.

The devices, procedures and circumstances are different, so results from cervical-cap insemination cannot be applied directly to a disc inserted after sex.

Does Semen Need to Be Kept Inside to Conceive?

When you are trying to conceive, semen leaking from the vagina can feel unsettling, but this is a normal part of intercourse. The amount of fluid retained is not a reliable indicator of whether sperm have reached the cervix.

The American Society for Reproductive Medicine (ASRM) states that sperm can be found in the cervical canal within seconds after ejaculation and in the fallopian tubes within minutes. Its guidance also says sexual position and post-sex routines have no known effect on fertility. You can read the full ASRM guidance on optimising natural fertility.

A disc may retain some fluid and reduce leakage, but we do not know whether this leaves more viable sperm available for fertilisation or increases the chance of pregnancy. You do not need to keep every drop of semen inside for conception to be possible.

How Do People Use a Menstrual Disc After Sex?

There is no medically established menstrual disc method. The following describes common community practice, but it is not a proven fertility protocol.

1. Time sex for the fertile window

People generally use the disc after vaginal sex during the days leading up to ovulation or around the time an ovulation predictor test turns positive. Timing sex for the fertile window is supported by evidence. Adding a disc is not.

2. Insert the disc after ejaculation

Community accounts commonly describe inserting the disc shortly after sex. There is no research showing that it must be inserted within a particular number of minutes.

Wash and dry your hands first. Pinch the disc into a narrow shape, insert it into the vaginal canal, aim it back and down towards the tailbone and tuck the front rim above or behind the pubic bone. A correctly positioned disc should feel comfortable. Do not force it into position.

3. Some people lie down, but it is optional

Some community routines include lying down for 10–30 minutes or elevating the hips. Research has not shown that either step improves conception after intercourse. You can get up, use the bathroom or continue with your day if you want to.

4. Leave the disc in for a variable amount of time

Community accounts range from around 30 minutes to several hours or overnight. No duration has been shown to work better for conception.

Follow the instructions for your specific product. Depending on the disc, the normal maximum wear time may be eight or 12 hours. Never exceed the recommended wear time or leave a menstrual disc in for longer than 12 hours.

5. Remove and dispose of or clean the disc

Hook the rim with a clean finger, keep the disc level as you remove it and empty the contents into the toilet or shower.

Dispose of a single-use disc as directed or wash a reusable disc according to the manufacturer’s instructions.

What Should You Consider Before Trying It?

Learn to use the disc before your fertile window

If a disc is new to you, practise insertion and removal when there is no pressure to get it right. Our menstrual disc dry-run guide can help.

Use a clean, undamaged product

Wash and dry your hands before insertion and removal. Follow the manufacturer’s cleaning and storage instructions for reusable discs.

Do not use a disc that is torn, cracked, sticky or otherwise damaged and do not share a reusable disc with another person.

Stay within normal wear guidance

There is no reason to exceed a product’s maximum wear time in the hope of improving the chance of pregnancy. Longer is not known to be better. Follow the instructions for your product and never exceed 12 hours, even if an online account describes doing so.

Choose for comfort, not conception claims

No disc size, firmness, shape or brand has been shown to improve fertility. The best option is one that fits comfortably, stays tucked and is easy for you to remove.

Our menstrual disc comparison chart and menstrual cups versus discs guide can help you compare normal product features.

Understand the limitations of menstrual discs

A menstrual disc does not provide contraception and does not protect against sexually transmitted infections. Menstrual discs have not been medically proven to increase the chance of conception when inserted after intercourse.

Stop if it causes discomfort

Remove the disc if you experience pain, persistent pressure, irritation or difficulty emptying your bladder.

Seek medical advice if symptoms continue after removal or if you experience unusual discharge, fever or other signs of infection.

Check with your fertility team

If you are having fertility testing or treatment, follow your clinic’s instructions. Ask before introducing a menstrual disc, particularly after procedures, while using vaginal medication or when you have been told to avoid inserting anything into the vagina.

What Matters More When Trying to Conceive?

Timing intercourse during the fertile window is better supported by evidence than trying to prevent semen from leaking out afterwards.

The fertile window is usually defined as the six days ending on the day of ovulation. Sperm can survive in the reproductive tract for up to five days, while an egg is generally available for fertilisation for about 12–24 hours after ovulation.

Healthdirect Australia recommends having vaginal sex every two to three days in the week before and around ovulation.

The American Society for Reproductive Medicine (ASRM) reports that having sex every one to two days during the fertile window produces the highest pregnancy rates, although two to three times a week is nearly as effective. Choose a frequency that feels manageable rather than turning sex into an exhausting schedule.

Cycle tracking, cervical mucus changes and ovulation predictor kits may help estimate fertile days, although no method predicts ovulation perfectly.

Our menstrual cycle guide, ovulatory phase guide and downloadable period tracker offer more background.

A preconception appointment can also help you review folic acid, medications, vaccinations, existing health conditions and lifestyle factors with a healthcare professional.

When Should You Seek Fertility Advice?

Using a menstrual disc should not delay a fertility assessment.

Healthdirect recommends speaking with a doctor if you have been trying to conceive for:

  • 12 months if you are 35 years old or younger
  • 6 months if you are 36 years old or older

Consider seeking advice sooner if you have irregular or absent periods, endometriosis, polycystic ovary syndrome (PCOS), a history of pelvic infection or surgery, a known sperm-related concern or another condition that may affect fertility.

Your GP can assess both partners where relevant and arrange testing or referral. See Healthdirect’s information about infertility for more guidance.

Frequently Asked Questions

Can a menstrual disc help you get pregnant?

We do not know. Some people report conceiving during a cycle when they used a disc after sex, but no good clinical trials have shown that the practice increases pregnancy rates. It is currently an unproven community method, not an established fertility treatment.

What is the Softcup or menstrual disc method for conception?

The Softcup method is a community term for inserting a menstrual disc after vaginal sex while trying to conceive. The name comes from the Softcup brand of disposable disc, although people now sometimes use the term when discussing reusable discs too. The aim is usually to keep semen near the cervix or reduce leakage, but it is not a standard or clinically proven protocol.

How soon after sex should you insert a menstrual disc?

Community accounts often describe inserting it shortly after sex, but there is no evidence-based time limit and no proof that inserting it immediately improves the chance of pregnancy.

How long should you leave a menstrual disc in after sex?

There is no proven wear time for conception. People report anything from 30 minutes to overnight. If you choose to try it, follow the instructions for your disc and never exceed its maximum wear time or 12 hours.

Do you need to lie down after sex?

No. You may lie down if it feels comfortable, but research has not shown that lying still, elevating the hips or using a particular sexual position improves fertility.

Is a reusable or disposable disc better for conception?

Neither has been shown to improve conception and there is no evidence that one type works better than the other. Choose based on fit, comfort, ease of removal, cost and your preference for reusable or single-use products.

Can you use a menstrual cup instead?

You may see similar accounts involving menstrual cups, but cups and discs sit differently and neither has been shown to improve pregnancy rates. A cup sits lower in the vaginal canal and forms a seal, while a disc sits in the vaginal fornix beneath the cervix.

Our Perspective

We do not claim that this method works because the research is not there. However, we also acknowledge the experiences of people who say they tried the method and later conceived.

If using a disc reduces leakage, makes the experience feel less stressful or gives you a greater sense of agency, you may decide it is worth trying. Use a clean, comfortable disc, stay within its normal wear instructions and keep your expectations realistic.

Conception does not depend on keeping every drop of semen inside or following a strict post-sex routine. Trying to conceive can already feel stressful, and incorporating any practice should not add anxiety or leave you feeling that you have reduced your chances by doing something “wrong”.
