conclusions our findings indicated that oxidative stress could play an essential role in male infertility caused by varicocele and may impair spermatogenesis leading to infertility. objectives in the current study, we aimed to assess the tac (total antioxidant capacity) and mda (malondialdehyde) as stress oxidative markers in infertile men with varicocele and fertile men, and moreover, their co...

OBJECTIVE To determine differences in use of the Internet related to infertility between infertile women and men, whether they benefit or are negatively affected from information on the Internet, and share this information with health professional. METHODS This cross-sectional study was carried out with 285 infertile women and 158 men between December 2015 and February 2016. Data were collect...

Research shows that men diagnosed with male factor infertility experience more suffering than men with infertility due to other causes, and that it is socially unfavourable to be diagnosed with male factor infertility resulting in secrecy surrounding diagnosis, sometimes to the point that women take the blame for the couples' infertility. We investigated mental and physical health, support, and...

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...

Varicocele is the most common diagnosis in men presenting to fertility clinics, Table 1.1 The incidence of varicocele in the general population has been reported to be 13.4% or greater, whereas 37% or more of infertile men have been noted to have varicoceles.2 The World Health Organization (WHO) investigated the influence of varicocele on fertility in men presenting to infertility clinics and c...

BACKGROUND An increasing number of reports suggest that chemical and physical agents in the environment, introduced and spread by human activity, may affect male fertility in humans. We investigated the relationships between exposure to environmental agents and seminal characteristics, and the concentrations of reproductive hormones in the serum of men seeking infertility treatment. METHODS W...

objective: in about 50% of infertile couples a male factor can be found to be present either alone or in addition to other female factors. a new molecular mechanism recently revealed to be involved in infertility is epigenetic pattern modification like as aberrant methylation. this mechanism can change or even silence gene expression. on the other hand, gstm1 (glutathione s-transferase mu 1) ...

There is accumulating evidence that workplace exposure to toxic substances contributes to male infertility. Men suffering from infertility problems may do well to look at their occupations, where exposure to certain substances may be a contributory factor, if not a direct cause, of infertility. Most of the studies to date are either case reports or epidemiological studies (population-based, cas...
