Problem: Recent studies show that lower genital tract infection with genital mycoplasma may be associated with the pathology of female infertility. However, this association remains controversial due to the variable prevalence, sample sizes, and different methods used to diagnose genital mycoplasma infection. The aim of the present meta-analysis was to gain better understanding of the specific impact of genital mycoplasma on female infertility.
Method Of Study: A systematic review of literature on the association of genital mycoplasma (Mycoplasma genitalium, Mycoplasma hominis, Ureaplasma parvum, and Ureaplasma urealyticum) infection and female infertility was performed using three electronic databases: PubMed, Scopus, and CINAHL, from January 2000 to January 2020. Pooled odds ratio (OR) and 95% confidence intervals for genital mycoplasma infection and female infertility were derived from a fixed effects model.
Results: This meta-analysis included eight studies conducted in six countries. Based on the results, women with infertility had a statistically higher odds of having any genital mycoplasma infection (p < .0001) compared to the control group. The pooled OR of all the included studies was 3.82 (95% CI: 2.55, 5.72). There was an unremarkable heterogeneity in all the studies included in this meta-analysis (I = 0%, p = .48). A subgroup analysis also showed that M. genitalium, M. hominis, and U. urealyticum infections are significantly associated with female infertility.
Conclusion: Our meta-analysis showed a significant association between M. genitalium, M. hominis, and U. urealyticum infections and female infertility. This evidence supports the development of guidelines for the diagnosis and treatment of genital mycoplasma infections to prevent female infertility.

Objective: Various facultative pathogenic bacteria have been detected in the dog's prepuce. To prevent the transmission of these bacteria, some breeders flush the prepuce of their stud dogs before mating. The purpose of this study is to find out whether preputial flushing is medically useful before mating.

Introduction: (UU) is a common pathogen associated with genital tract infections in infertile males. However, its impact on semen quality, embryo development, and fertilization (IVF) outcomes remains underexplored. This study aims to evaluate the effect of male UU infection on semen parameters, embryo development, pregnancy outcomes, and neonatal health in infertile couples.

Article Synopsis
- Genital Mycoplasmas are linked to negative pregnancy outcomes and infertility, but more research is needed to understand their exact role.
- The study analyzed 228 endocervical samples from pregnant and non-pregnant women using end-point PCR to detect various Mycoplasma species.
- The findings showed that certain Mycoplasma species were associated with bacterial vaginosis, indicating a potential contribution to its development, though no clear link was found to infertility or adverse pregnancy outcomes.

Article Synopsis
- - The study investigated the role of a specific microorganism in canine infertility, analyzing 114 cases of abortion, stillbirth, and neonatal mortality in dogs from Central Italy, but findings were mixed and only a small percentage tested positive.
- - Out of the cases studied, 6.14% showed a positive result for the microorganism's DNA, with some cases also identifying other pathogens known to cause infertility and neonatal issues.
- - The presence of the microorganism in the female reproductive tract suggests it may be a normal part of the genital microflora, rather than a direct cause of abortion or neonatal death in most cases.

Article Synopsis
- The study investigated how cervical load and bacterial DNA prevalence differ in pregnant women with preterm prelabor rupture of membranes (PPROM), particularly focusing on those with and without a history of cervical excisional treatment.
- Women who had cervical excisional treatment showed higher cervical loads of specific bacterial DNA compared to those without such a history.
- Additionally, the length of the excisional cone influenced the bacterial DNA levels, suggesting that longer cone lengths were associated with distinct microbiota changes.*
