Part of Infections, Women’s health & pregnancy clinical trials.

This study looks at whether differences in the gut (microbiome) are linked to how long it takes to get pregnant and pregnancy outcomes. It may help researchers understand who might benefit from future microbiome-focused approaches.

How Gut Bacteria Affect IVF Success in Couples

This study examines how the bacteria in your gut and your partner's gut may affect the success of IVF (in vitro fertilization) treatment. Researchers will collect samples and health information from couples before IVF to see if certain bacterial patterns predict better pregnancy outcomes.

Study of gut microbiome in weight-related pregnancy outcomes

This study looks at differences in the gut’s living microbes (microbiome) in people who are trying to conceive or are early in pregnancy, and how that may relate to pregnancy outcomes. It may help researchers understand whether microbiome changes are linked to healthier—or more complicated—pregnancies.

Restoring gut bacteria after C-section birth

This trial tests whether giving a small dose of the mother's vaginal bacteria to babies born by C-section can help restore their gut microbiome. It may reduce the risk of allergies and other immune-related conditions later in life.

Using mother's gut bacteria to help preterm babies

This study is testing whether giving a special transplant of healthy bacteria from the mother's gut can help improve the gut health of babies born early (preterm). It is for pregnant women at high risk of preterm labor between 29 and 34 weeks of pregnancy.

Study of how healthy babies’ gut microbes develop from birth

This study follows pregnant people from about 20 weeks until delivery, to understand how gut microbes (tiny organisms in the intestines) develop in healthy babies. It may help researchers learn how early-life gut development affects health later on.

Restore gut bacteria in newborns using special microbiome samples

This study looks at whether restoring a newborn’s gut bacteria (microbiome) can improve early health. Babies are treated based on the birth conditions, especially whether delivery was vaginal or by C-section.
