Sex, puberty, and the gut microbiome

Area of Science:

• Microbiology
• Human Health
• Sex Differences

Background:

• The gut microbiome plays a crucial role in sex-specific physiological processes and diseases.
• Understanding sex differentiation of the gut microbiome is vital for host health and disease management.

Purpose of the Study:

• To review evidence of microbial sex differences in puberty and adulthood.
• To explore potential mechanisms driving sex-specific gut microbiome development.
• To identify research gaps and future study directions.

Main Methods:

• Literature review of existing studies on sex differences in the gut microbiome.
• Analysis of evidence for microbial maturation during and after puberty.
• Examination of potential mechanisms including sex steroids, bile acids, and the immune system.

Main Results:

• Evidence suggests the gut microbiome continues to mature in a sex-dependent manner during and after puberty.
• Sparse literature exists on mechanisms driving sex-specific gut microbiome differentiation.
• The existence of a sex-specific gut microbiome is strongly supported by current data.

Conclusions:

• The gut microbiome exhibits significant sex-specific differences that emerge during adolescence.
• More research is required to elucidate the host-microbe interactions responsible for these sex-specific microbial communities.
• Future studies should focus on understanding the maturation processes and health implications of sex-specific gut microbiota.
