Probiotics have gained attention for their potential role in improving fertility, but how exactly do they work? Let’s explore the connection between probiotics, the vaginal microbiota, and female fertility.
What Is the Vaginal Microbiota?
The vaginal microbiota, also known as vaginal flora, is the collection of bacteria that live in the female genital area and perform essential protective functions. Most of these bacteria are of the Lactobacillus genus, which help prevent the growth of harmful microorganisms.
Does Semen Have a Microbiota?
Yes, semen also contains a variety of non-pathogenic bacteria, including Lactobacillus and Streptococcus. This collection of bacteria is referred to as the seminal microbiota.
What Happens If My Vaginal Microbiota Changes, and Can It Affect My Fertility?
The vaginal flora serves a protective function, but if the balance of Lactobacillus decreases and other bacteria increase, a condition called vaginal dysbiosis occurs. The most common type of dysbiosis is bacterial vaginosis, and it can negatively impact fertility. Dysbiosis affects endometrial receptivity, which is the ability of the endometrium to interact with an embryo for implantation. As a result, an imbalance in the vaginal microbiota may be the cause of failed implantation and/or miscarriage.
Does Vaginal Flora Affect In Vitro Fertilisation (IVF) Treatments?
Research has shown a significant link between IVF success and the vaginal microbiota. Studies suggest that women undergoing IVF treatments who have bacterial vaginosis experience lower pregnancy rates. In contrast, a balanced vaginal flora, dominated by Lactobacillus and with a low concentration of other bacteria, is associated with better reproductive outcomes during IVF. Specifically, dysbiosis can affect two crucial phases of IVF: ovarian stimulation and embryo transfer.
Probiotic Treatment: Yes or No?
Yes! Probiotics, which contain various strains of Lactobacillus, are recommended when there is an imbalance in the vaginal flora. These supplements help restore the balance of the vaginal microbiota, improving the chances of successful conception, both naturally and through assisted reproduction treatments like IVF.
