BACKGROUND To study the prevalence of Chlamydia infection in women with primary and secondary unexplained infertility using ELISA technique for antibody detection and real time, fully automated PCR for antigen detection and to explore its association with circulating antisperm antibodies (ASA). METHODS A total of 50 women with unexplained infertility enrolled in this case control study and a ...

BACKGROUND Serotonin is a neurotransmitter that modulates a wide range of neuroendocrine functions. However, excessive circulating serotonin levels may induce harmful effects in the male reproductive system. The objective of this study was to evaluate whether the levels of urinary 5-hydroxyindoleacetic acid (5-HIIA), a major serotonin metabolite, correlate with different classical seminal param...

Infertility is a common yet complex problem affecting approximately 10-15% of couples attempting to conceive a baby. Especially, 40-50% of these factors are known as male-related disorders. Unlike female infertility, the cause of which is often easily identified, diagnosing male factors can be difficult. Male infertility is due to low sperm production, abnormal sperm function or blockages of sp...

BACKGROUND Infertility can be a major concern for couples trying to conceive, and occupational hazards may constitute a main cause of infertility in men. Studies conducted throughout the world indicate that physical and chemical hazards in the workplace can have a negative impact on male fertility. The main objective of this study was to determine the frequency of occupational categories of men...

The expert panel made a tremendous effort to propose guidelines on the emerging trends of sperm DNA fragmentation testing and its clinical utility based on the available latest scientific evidence (1). Panel presented it in a systematic manner by a practical approach with four common clinical case scenarios. In the er...

background and aims: sexually transmitted infections (stis) are of major concern to clinicians and researchers in the field of reproductive medicine. many sti pathogens cause incurable and often fatal diseases, and have been transmitted through insemination procedures. the role of herpes simplex virus in male infertility has been investigated using the sensitive methods. the aim of this study w...

Male factor infertility is a complex disorder, affecting approximately 10-15% of couples worldwide, however many of its aetiologies are unknown [1,2]. With the advent of assisted reproductive technology (ART), men with sub-optimal sperm quality are now able to overcome natural selection mechanisms and produce viable offspring [3]. Since ART is a relatively new phenomenon, the impact of inherita...

Male infertility represents one of the clearest examples of complex phenotype with substantial genetic basis. It is indeed well established that genetic causes account for 10-15% of infertility cases, including chromosomal abnormalities and single-gene mutations. However, a large proportion of infertile males does not receive a clear diagnosis and thus they are reported as idiopathic or unexpla...

BACKGROUND Ubiquitin, a house-keeping protein that marks other proteins for proteasomal degradation, tags defective sperm during epididymal passage. To establish ubiquitin as a biomarker of human infertility, the present study examines the relationships between sperm ubiquitin content and clinical semen parameters among men from an infertility clinic population with varied aetiologies. METHOD...

Men with idiopathic infertility generally present with significantly higher seminal ROS levels and lower antioxidant properties than healthy controls [3]. Therefore, it appears that the presence of OS in infertile normozoospermic men may be the cause behind previously unexplained cases of infertility. Similarly, sperm DNA damage analysis may reveal hidden sperm DNA abnormalities in infertile me...
