We're launching a study to better understand how the microbiome may impact IVF treatment.

Going through IVF? Your participation could contribute to science to better understand how the vaginal and gut microbiome may impact IVF treatment. In partnership with Matthew Foley, Ph.D., we intend to publish our findings when the study concludes.

Recruitment starts June 2024

For Adults between 18-38 years old (see criteria)

19-26% of women face challenges related to reproductive and fertility outcomes.

12% of women experiencing infertility turn to assisted reproductive treatments, predominantly in vitro fertilization (IVF). This results in an astounding 400,000 IVF cycles per year nationwide[1].

Research has shown an association between the gut and vaginal microbiomes and a variety of pregnancy complications such as gestational diabetes, pre-term labor, and preeclampsia[2]. An imbalance in the delicate vaginal ecosystem can also impact fertility outcomes and IVF success[3], various studies have found that a vaginal microbiome dominated by Lactobacillus species to be significantly associated with successful conception and healthy pregnancies[4],[5],[6].

The goal of this study is to assess how the vaginal and gut microbiome may impact IVF outcomes. Adult participants, who are undergoing IVF treatment and purchase a Tiny Health vaginal or vaginal + gut test, may consent to have their data used in this study. Each participant will agree to fill out a survey on pregnancy outcomes after implantation results are known.

About Tiny Health

Tiny Health was created for mom and baby

Tiny Health offers at-home gut tests for the whole family. We focus on a baby’s first 1,000 days to address imbalances that may cause chronic conditions such as allergies. Processed in a CLIA-certified lab and using comprehensive shotgun metagenomics sequencing, Tiny Health gives parents personalized insights and evidence-based recommendations to improve a baby’s lifelong health.

Tiny Health’s mission is to improve health outcomes of future generations through evidence-based insights.

About the study's principal investigator

Our research partner develops virome therapeutics

It's not only about the bacteria...

At least half of the microbiome is made up of viruses, which can infect and kill beneficial bacteria, contributing to dysbiosis and disease. The "virome" is the term coined for the collection of all viruses within your microbiome.

Our research partner, Dr. Foley, represents a virome therapeutics company that seeks to investigate which viral profiles shape the bacterial community and impact IVF outcomes.

Purchase the kits, sample, and complete surveys

This study is open to people who have purchased a Tiny Health Vaginal Test or Gut Health Test.

Complete the qualification survey via the button on this page to see if you qualify.

If you qualify for the study, you will receive a link to purchase a Research Edition Tiny Health Vaginal Health test or a combination Tiny Health Vaginal Health and Tiny Health Gut Health test at a discount.

To investigate the important connection between IVF success and gut health, participants must also agree to complete a short survey approximately 4-8 weeks after embryo transfer to share pregnancy results.

Both vaginal and gut samples can be taken at home by using our swab method. Samples will be mailed in using a prepaid envelope provided with the kit.

You will fill out health history and sample surveys upon sampling.

Processed in a CLIA-certified lab and using proprietary technology, Tiny Health’s vaginal health test and gut health test provides strain-level precision and a complete list of all microbes in the vaginal and gut microbiome including bacteria, fungi, virus, parasites, and archaea. Results will take 4-5 weeks to arrive.

Every report includes key insights and metrics that are reviewed by a team of microbiome experts.

  • Tiny Health also provides actionable and evidence-based recommendations to people trying to conceive, are currently pregnant, or postpartum.
  • The microbiome result report and action plan are a part of the regular Tiny Health Vaginal and Gut Health Test product and not associated with the research study.

To study important connections between the microbiome and IVF success, it is critical that participants complete a follow up survey after embryo transfer on pregnancy results.

Participants who have consented to the study will receive a link to this follow up survey via email.

Frequently Asked Questions

Data exposure: Tiny Health will collect personal identification information such as names, emails, addresses, and health information via online surveys. The risk of personal information or microbiome data being exposed is a possibility. To prevent this risk, all personal information is stored in encrypted databases with access limited to dual authentication select employees. Stool and vaginal samples are de-identified using a kit id before being sent to partners for DNA extraction and sequencing.

While microbiome testing does not diagnose fertility factors, we can show associations between your vaginal microbiome and vaginal health.

How do we do this? We use the relative abundance of key bacteria as indicators of vaginal health. These evaluations are developed through research. The Tiny Health Bioinformatics Pipeline uses a custom built database of over 120K complete microbial genomes. We sift through the research surrounding the microbiome and use this information to develop a list of bacteria that we feel are important to vaginal health.

Beyond the vaginal and gut microbiome, there are a lot of factors that can contribute to fertility status.

It's important to the study that vaginal and gut samples are taken within 3 months BEFORE embryo transfer.  However, this study will continue until June 2025, so please return when qualified to be eligible for this research edition discounted kit.
