The impact of puberty on Girl's Microbiota
What happens to a girl’s microbiota as she grows up? From early childhood to puberty, the microbiota gut, skin, and vaginal evolves constantly. Diet, environment, hygiene habits, and hormones all play a role.
But what’s normal? How do puberty and periods change things? Why do some girls get more infections or skin issues than others? Backed by science, this section explores how these microbial shifts can affect immunity, mood, and overall health and how girls can support their microbiota every step of the way.

Microbiota development in children
Before talking about puberty, let's discuss microbiota development in children. From the gut to the skin, a child’s microbiota plays a key role in their health, shaped by early-life stages, allergies, and environmental factors. Explore how microbes impact immunity and disease risk in children's life.
What about the gut microbiota
What do we really know about how a child’s gut, skin, or vaginal microbiota develops? From colic to antibiotics, and immunity to early life stages, explore the latest research answering parents’ top questions about the microbiota's role in child health.
What about allergies?
Childhood allergies, including food, respiratory, and skin allergies, are increasingly linked to microbiota development. Explore how early microbial influences shape allergy risks from pregnancy to early childhood.
Impact of environment on a child’s microbiota
How does the environment shape a child’s microbiota?
From exposure to nature to daily interactions with pets and family, explore the latest research on how environmental factors influence gut, skin, and other microbiomes in childhood development.

Intimate hygiene & girl's microbiota
What does your hygiene have to do with your microbiota? A lot, actually! From your period to daily habits, the way you care for your body can shape your vaginal and gut microbiotas and protect you from infections like UTIs or thrush. Want to know what’s normal, what’s not, and how to stay balanced? Let’s clear things up.
How is microbiota formed?
How is a girl’s microbiota formed, and why does it matter for her health? From birth to adolescence, learn how her gut and intimate microbiota shape hygiene, immunity, and well-being, with tips for girls to maintain balance as they grow.
How to take care of your intimate microbiota
How does a girl’s microbiota affect her health? From vaginal hygiene to menstruation, early habits shape the balance of gut and vaginal microbiotas. Discover why understanding and protecting these ecosystems from a young age is key to preventing infections, bacterial vaginosis, or toxic shock syndrome.
Vaginal infections & microbiota
Vaginal and intimate infections in girls are linked to microbiota imbalances. But what causes these imbalances? Discover how hygiene, lifestyle, and diet affect the vaginal microbiota, and learn about these infections and how to prevent them.

Puberty, hormones & microbiota
Puberty triggers hormonal changes that have a profound effect on the microbiota across the gut, skin, and intimate regions. Delve into how these shifts influence key aspects of teen health, from mood and skin conditions like acne to overall well-being.
Fluctuating hormones & intimate microbiota
Puberty brings hormonal fluctuations that can significantly affect the intimate microbiota. Explore how these hormonal changes impact the vaginal microbiome, and dive into the latest findings on how hormones and contraceptives shape microbiota health.
First periods & intimate microbiota
The onset of periods marks a major change, but how does it affect the intimate microbiota? Discover why you may experience painful periods and how the menstrual cycle, contraceptives, and the vaginal microbiome are all connected.
Caring for the intimate microbiota
Caring for the intimate microbiota is key to health, especially during puberty. Discover how to maintain a balanced vaginal microbiome and prevent infections like bacterial vaginosis with the latest insights on hygiene and hormones.
Other impact of puberty on teenagers
Puberty brings significant hormonal changes that deeply influence the microbiota. Discover how these shifts affect the gut, skin, and intimate microbiomes, playing a key role in mood, acne, and overall well-being during the teenage years.





What women know (and don't know)
about their vaginal microbiota
What is the link between microbiota and women’s health? The International Microbiota Observatory, based on a survey of 7,500 people across 11 countries, explores women’s knowledge, perceptions and behaviours of their gut, vaginal, and urinary microbiota. The 2024 edition reveals a global lack of awareness, growing interest in the role of microbiota in hormonal, digestive, and intimate health, and a strong demand for better prevention, education, and support. Dive into the full report to discover key insights, data highlights, and what women worldwide really know about their microbiota.
