Endometrial Microbiome and Its Correlation to Female Infertility

The human body hosts a vast number of natural microorganisms, collectively known as the microbiome, which includes bacteria, viruses, and fungi. Humans have co-evolved with these trillions of microorganisms, adapting to physiological changes over time.
The balance of the microbiome varies across different organs in the body. Previously, it was believed that the uterus was sterile. However, advancements in medical technology and bacterial gene sequencing have revealed that the uterus has its unique microbiome, which can be categorized into two main types:
Lactobacillus-dominant, accounting for over 90% of the endometrial microbiome
Lactobacillus non-dominant, accounting for less than 90% of the endometrial microbiome, with other bacterial species being more dominant
An imbalance in the microbiome, particularly a reduction in Lactobacillus dominance, can lead to a condition known as dysbiosis. Studies analyzing endometrial fluid or tissue samples have identified a significant correlation between the endometrial microbiome and female infertility. Research indicates that a Lactobacillus-dominant microbiome enhances endometrial receptivity, thereby increasing the chances of pregnancy compared to women whose microbiomes are dominated by other bacterial species.
It has been shown that the administration of carefully selected probiotics, often following antibiotic treatment, can help restore a symbiotic microbiota. This restoration can potentially increase the success rates of pregnancy and improve outcomes in assisted reproductive technology (ART) treatments.
However, these studies lack consistency in clinical settings, particularly regarding the administration routes of Lactobacillus probiotics, which may be either oral or vaginal, as well as the dosage and duration of treatment.

PPOS: Innovative Approach to Ovarian Stimulation
PPOS (Progestin-primed Ovarian Stimulation) is a novel approach to stimulating ovulation in women undergoing procedures such as egg freezing or in-vitro fertilization (IVF).

PICSI – Another Way, Another Hope
Modern infertility treatments are increasingly enhanced by advanced technologies that significantly boost the chances of pregnancy. One widely used method is ICSI (Intracytoplasmic Sperm Injection), which allows for the selection of a single sperm to inject directly into the egg. [1,7] Since sperm quality plays a crucial role in fertilization and embryo development, ICSI has become an important tool in assisted reproduction. However, ICSI primarily selects sperm based on their morphology and motility, without insight into the sperm’s internal quality. This limitation has led to the development of an advanced technique known as PICSI, which helps further refine sperm selection, offering a promising solution for couples facing infertility caused by poor sperm quality.

Tooth Cavity: What Should You Do? Recognize the Signs of Tooth Decay Before It Becomes Too Severe to Treat
A tooth cavity develops when acids produced by bacteria dissolve the enamel and dentin, creating a permanent hole that the body cannot repair on its own. Early cavities often cause no pain and may appear as small black spots or tiny holes. Treatment typically involves removing the decayed tooth structure and filling the cavity. If the decay reaches the dental pulp, root canal treatment or tooth extraction may be necessary.
