Background: is an infrequent, but one of the most successful bacteria that associated with infertility and are able to spermatozoa immobilization and agglutination.
Objective: The aim of present study was to determine the frequency of in semen obtained from infertile male patients in northwest Iran.
Materials And Methods: Seminal fluids of 100 infertile men were evaluated. Standard semen examination was done according to World Health Organization guidelines. After isolation and identification of isolates according to reference methods, determination of susceptibility against important antibiotics and polymerase chain reaction were performed to identify and genes.
Results: Data obtained from the present study shows that 16% of infertile male patients were colonized by . Ten (62.5%) of the individuals had abnormal seminal fluid sperm motility and morphology and three (18.8%) of them had an abnormal seminal fluid density, whereas after washing with albumin-saline declined to 5 (31.3%), 4 (25%) and 1 (6.3%), respectively. The antibiogram results showed that, except penicillin, other antibiotics have high activity on isolates. Regarding polymerase chain reaction results, sequences were detected in 3 (18.7%) strains, whilst the gene encoding TSST-1 was not detected in any of clinical strains.
Conclusion: It would appear that the may be an additional negative factor worsening sperm quality and affecting male fertility. Therefore, it demands that all the patients attending in infertility treatment facilities be investigated thoroughly.

Objectives: Acetylated tubulin is a hallmark of flagellar stability in spermatozoa, and studies have demonstrated the ability of CDYL to function as a tubulin acetyltransferase in spermatozoa. Of note, germline conditional knockout of Cdyl can lead to asthenoteratozoospermia and infertility in male mice. However, the role of CDYL gene in human fertility remains uncharacterized.

The accurate callose deposition plays important roles in pollen wall formation and pollen fertility. As a direct target of miRNA160, ARF17 participate in the formation of the callose wall. However, the impact of ARF17 misexpression in microsporocytes on callose wall formation and pollen fertility remains unknown.

Background Sexual intercourse frequency (SIF) is widely known to be associated with fertility, but little is known about what predicts SIF among infertile couples trying to conceive. In this study, we examine the demographic and lifestyle risk factors associated with less frequent coitus among infertile couples. Methods This cross-sectional study examined infertile couples actively trying to conceive, selecting them from patients seeking fertility treatment.

Introduction: Despite the global prevalence of low fertility rates, male contributions to fertility and reproductive health outcomes have been understudied. This study aims to investigate the male contribution to fertility and explore the underlying biological mechanisms. Specifically, we aim to (1) identify male factors associated with successful pregnancy, (2) develop a fertility index incorporating modifiable factors for both males and females to predict pregnancy rate and (3) explore the relationship of male modifiable factors with semen parameters and molecular characteristics.
