Uterine microbiome-low biomass and high expectations†

Area of Science:

• Reproductive biology
• Microbiome research
• Female reproductive tract health

Background:

• The traditional view of a sterile fetal environment is challenged by the presence of diverse bacterial communities in the female reproductive tract.
• A clear understanding of the physiological microbiota in the upper reproductive tract of most women (outside of infection or pregnancy) is lacking.
• The role of bacteria in the upper reproductive tract concerning uterine diseases and pregnancy outcomes remains poorly established.

Purpose of the Study:

• To investigate the uterine microbiome and enhance understanding of the female reproductive tract.
• To highlight the importance of microbiological assessment in infertile patients for personalized reproductive therapies.
• To address the lack of standardization in uterine microbiome studies.

Main Methods:

• Review of existing literature on uterine microbiome sequencing.
• Identification of areas needing improvement and standardization in study design, sampling, DNA extraction, sequencing, and data analysis.
• Emphasis on the need for further microbiological investigations.

Main Results:

• Current studies on the uterine microbiome have limitations due to non-standardized methodologies.
• There is a lack of consensus on the composition and function of the physiological uterine microbiota.
• The clinical significance of the uterine microbiome in reproductive health is not fully elucidated.

Conclusions:

• Standardization of methodologies is essential for advancing uterine microbiome research.
• Further investigation is required to elucidate the role of the uterine microbiome in reproductive health and disease.
• Microbiological assessment holds potential for personalized reproductive medicine, particularly in cases of infertility.
