Exploring and Validating Biomarkers in Menstrual Blood

This study wants to find out if menstrual blood, collected using a simple cup, can give us the same important health clues as traditional blood tests from your arm. Researchers think menstrual blood might hold valuable information about women's health and fertility, which hasn't been studied enough. They'll compare these samples to see if menstrual blood could become a useful and less uncomfortable way to gather health information. While it won't help participants directly, it could lead to better research into women's health and fertility in the future. Women aged 18 and over who have periods might be invited to join.

What is this study about?

This study is a really important step towards understanding more about women's health, particularly when it comes to fertility. For a long time, research into menstrual and reproductive health hasn't received as much attention as other areas. We know that menstrual blood is a natural part of a woman's cycle and could potentially contain lots of useful information about her body, similar to what we learn from a standard blood test taken from an arm, or even more involved procedures like uterine biopsies or vaginal swabs.

The main goal is to see if we can get the same kind of helpful biological information from menstrual blood as we do from these other methods. This could mean that in the future, it might be possible to use a simpler, less invasive way to gather information for research into women’s and reproductive health. This could make it easier and more comfortable for people to take part in studies.

Researchers will also look at how easy it is to collect these samples in a clinic and whether laboratories can reliably process them. Ultimately, if successful, this research could open doors to new ways of studying and understanding fertility and other aspects of women's health.

Key takeaways

  • This study explores using menstrual blood for health research.
  • It aims to find a simpler way to gather information about women's health.
  • Participation involves one clinic visit during your period and two simple samples.
  • You won't receive personal health results, but your contribution is valuable for future research.
  • The study is considered low risk and has no direct medical benefit.
  • You can withdraw from the study at any time.

Who may be eligible?

You might be able to join this study if you are a woman aged 18 or older and currently have periods (you haven't gone through menopause). It's important that you are willing and able to use a menstrual cup to collect a sample and also give a small blood sample from your arm. You should also be able to understand what the study involves and agree to take part by giving your written consent.

There are a few reasons why you might not be able to join. For example, if you are pregnant, under 18, or have gone through menopause, this study isn't for you. Also, if you have a current infection in your vagina or pelvis, or any other health condition that would make using a menstrual cup unsafe or simply unsuitable for the study, you wouldn't be able to participate. This includes having an allergy to the material of the menstrual cup.

Could this study suit you?

Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.

  1. Are you female and aged 18 or older?
  2. Do you currently have periods (you haven't gone through menopause)?
  3. Are you comfortable using or willing to use a menstrual cup?
  4. Are you able to provide a small blood sample from your arm?
  5. Do you understand what the study involves and are happy to give your consent?
  6. Are you pregnant or do you have an active infection that might prevent you from joining?
Answer every question to see your result.

What does participation involve?

If you decide to take part, you'll first be given detailed information about the study to read carefully, and you'll have time to think about it and ask any questions. If you agree, you'll sign a consent form.

You would need to attend one study visit while you are having your period. During this visit, a trained member of staff will take a small blood sample from a vein in your arm. This is a common procedure, often part of routine care. You will also provide a menstrual blood sample, which you will collect using a menstrual cup. The samples will then be sent to a lab for analysis. There are no medications involved in this study, and no further follow-up visits are needed after this one.

Potential risks and benefits

This study is considered to be of low risk. Potential risks might include minor discomfort or bruising from the arm blood sample. There is no direct medical benefit expected for you by taking part, meaning you won't get individual health results. However, your contribution is valuable as it could help researchers understand if menstrual blood can be used more widely in future women's health and fertility research, which could benefit many others. You have the right to withdraw from the study at any time without giving a reason, and it will not affect your care.

Common questions

Will I get results about my own health?

No, the tests are for research only and won't give you individual health information. They are not designed to tell you about your specific health condition.

What is a menstrual cup?

A menstrual cup is a small, flexible cup that you insert into your vagina during your period to collect menstrual fluid.

How long will my visit to the clinic be?

The study visit will involve collecting blood from your arm and your menstrual blood sample, but the exact duration isn't specified. It should be a single visit during your period.

Is this study safe?

Yes, this study is considered low risk. Staff are trained, and precautions are taken to ensure your safety and comfort.

Can I still withdraw from the study after I've agreed?

Yes, you can withdraw from the study at any time without having to give a reason, and it will not affect any care you receive.
