Vagina
The vaginal microbiota in pregnancy varies markedly during the entire time of gestation. The species and diversity of the microorganisms may be related to the various levels of hormones during pregnancy.[1]
Placenta
Uterus
The healthy uterine microbiome has been identified and over 278 genera have been sequenced.[2]
Ovarian Follicle
The ovarian follicle microbiome has been studied using standard culturing techniques.It has been associated with the outcomes of assisted reproductive technologies and birth outcomes. Positive outcomes are related to the presence of Lactobacilli spp while the presence of Propionibacterium and Actinomyces were related to negative outcomes. Also, the microbiome can vary from one ovary to the other. Studies are ongoing in the further identification of those bacteria present.[2]
Male reproductive tract
The microbiome present in seminal fluid has been evaluated. Using traditional culturing techniques the microbiome differs between men who have acute prostatitis and those who have chronic prostatitis. Identification of the seminal fluid microbiome has become one of the diagnostic tools used in treating infertility in men that do not display symptoms of infection or disease. The taxa Pseudomonas, Lactobacillus, and Provotella display a negative effect on the quality of sperm. The presence of Lactobacillus spp in semen samples is associated with a very high normal sperm count.[2]
