Administration of oral probiotic (comprising of Lactobacillus rhamnosus BPL205, Lactobacillus crispatus BPL209 and Lactobacillus plantarum BPL207) can restore vaginal health and create a more conducive environment for fertility.
A prospective pilot study recently published in the prestigious 'Human Reproduction' journal by E González et al. has unveiled a potential game-changer for women seeking to improve vaginal flora and enhance fertility using an oral probiotic regimen consisting of Lactobacillus rhamnosus BPL205, Lactobacillus crispatus BPL209, and Lactobacillus plantarum BPL207.
The research, which involved 21 women attending a fertility clinic with indications of vaginal microbiota restoration and a low number of vaginal Lactobacillus bacteria, showcased remarkable outcomes. The objective of the research was to evaluate how a 10-week usage of an oral probiotic along with vitamin D supplementation, impacts the restoration of vaginal health.
At the study's commencement, all participants exhibited a vaginal pH level exceeding 4.5, indicating an imbalance in the vaginal environment. However, after just 5 weeks of consistent use of the oral probiotic supplement, 66.7% of the participants achieved a vaginal pH below 4.5. The results became even more impressive after 10 weeks of probiotic supplementation, as all participants achieved the desired vaginal pH level. The cytology results at the study's outset displayed an unhealthy vaginal flora profile, except for a single participant.
However, after only 5 weeks of oral probiotic use, 73.7% of the participants experienced a transformation to a healthy vaginal flora, rich in Lactobacillus dominance—a critical factor in controlling the proliferation of harmful pathogens. The positive impact continued to strengthen, with 89.5% of participants achieving a healthy vaginal flora profile after 10 weeks of probiotic supplementation. Furthermore, the study unearthed significant reductions in menstrual pain over time.
Initial menstrual pain, measured at an intensity of 6.1 ± 1.8 (mean ± standard deviation), dropped to 3.8 ± 3.5 after 5 weeks of probiotic use and a remarkable 1.5 ± 3.0 after 10 weeks (p = 0.01 and p < 0.0001, respectively). For patients diagnosed with chronic endometritis at the study's outset (n = 5), the use of the oral probiotic led to a noteworthy decline in TNF-α levels from 8.14 ± 1.8 to 5.59 ± 2.3 after 10 weeks (p = 0.02), indicating an improvement in inflammatory conditions.
The study's primary limitation lies in the relatively small number of recruited patients. However, the research team acknowledges this constraint and plans to expand the study cohort to enhance the study's robustness. Additionally, the ongoing study continues to explore and expand the number of parameters being examined.
Encouraging Outlook for Women's Health and Fertility…
These findings carry profound implications for women's health and fertility. This discovery not only provides a beacon of hope for women striving to conceive but also offers a potential avenue for managing inflammatory conditions.
