Primary infertility is here defined as never having conceived before, secondary infertility as infertility subsequent to having conceived at lea...

BACKGROUND & OBJECTIVES Recently, a significantly higher ratio of nucleotide changes in the mtDNA genes: COII, ATPase 6, ATPase 8, ND2, ND3, ND4, and ND5 was reported in spermatozoa from populations of infertile Indian men, compared suggesting that screening for mtDNA mutations could provide insight into the aetiology of male infertility. In this study, we examined the published data and found ...

Zinc is an essential trace mineral for the normal functioning of the male reproductive system. Current studies have investigated the relationship between seminal plasma zinc and male infertility but have shown inconsistent results. Hence, we systematically searched PubMed, EMBASE, Science Direct/Elsevier, CNKI and the Cochrane Library for studies that examined the relationship between seminal p...

BACKGROUND Genital ureaplasmas (Ureaplasma urealyticum and Ureaplasma parvum) and mycoplasmas (Mycoplasma genitalium and Mycoplasma hominis) are potentially pathogenic species playing an etiologic role in both genital infections and male infertility. Reports are, however, controversial regarding the effects of these microorganisms infections in the sperm seminological variables. This study aime...

Varicocele is often cited as the most common cause of male factor infertility. Arguments in support of this statement include reports of increased prevalence of varicocele in populations of infertile men compared with fertile or otherwise unselected men, association of varicocele with abnormal semen parameters, and improvements in semen parameters and/or pregnancy rates after varicocele repair....

background: mycoplasmas can cause acute and chronic diseases at multiple sites with wide-range complications and have been implicated as cofactors in diseases. the infections influenced form genital mycoplasmas specifically mycoplasma hominis and mycoplasma genitalium potentially affect reproductive disorders, and infertility. objective: isolation and molecular identification of mycoplasma geni...

Chlamydia trachomatis is the most common cause of sexually transmitted diseases that is not of viral origin and there is accumulating evidence of a significant role played by this pathogen in causing male factor infertility. This study thus aimed to determine the prevalence of C. trachomatis among infertile males and to evaluate their association with fertility status and abnormal semen charact...

This study was undertaken to determine the prevalence of Chlamydia trachomatis, Mycoplasmas, and Ureaplasmas in semen samples of the male partners of infertile couples and to investigate whether Chlamydia trachomatis could initiate apoptosis in human spermatozoa. A total of 85 males partners of infertile couples undergoing routine semen analysis according to World Health Organization guidelines...

A recent genetic analysis of infertile globozoospermic patients identified causative mutations in three genes: a protein interacting with C kinase 1 (PICK1), dpy 19-like 2 (DPY19L2), and spermatogenesis associated 16 (SPATA16). Although mouse models have clarified the physiological functions of Pick1 and Dpy19l2 during spermatogenesis, Spata16 remains to be determined. Globozoospermic patients ...
