        Are There Relationships between Seminal Parameters and the Neutrophil-to-Lymphocyte Ratio or the Platelet-to-Lymphocyte Ratio?

        Serdar Aykan,Lütfi Canat,Serkan Gönültaş,Hasan Anıl Atalay,Fatih Altunrende 대한남성과학회 2017 The World Journal of Men's Health Vol.35 No.1

        Purpose: The aim of this study was to evaluate the relationship of seminal parameters with the neutrophil-to-lymphocyte ratio (NLR) and the platelet-to-lymphocyte ratio (PLR), which are inflammatory markers, in men with an abnormal semen analysis and men with normozoospermia.Materials and Methods: Fifty-seven men with abnormal semen analyses and 59 men with normozoospermia were included in this cross-sectional study. A complete blood count was recorded, and the NLR and PLR were calculated from the hematologic parameters.Results: The NLR was 1.84±0.78 in the normozoospermic group and 1.80±0.75 in the abnormal semen analysis group. The PLR was 95.32±35.47 in the normozoospermic group and 93.57±28.09 in the abnormal semen analysis group. No significant differences were found between the normozoospermic and the abnormal semen analysis group in the NLR (p=0.828) or the PLR (p=0.768). In addition, no seminal parameters were correlated with the NLR or the PLR (p>0.05).Conclusions: We do not recommend using the NLR or the PLR as markers to screen for abnormal semen parameters or male infertility.

        Are Platelet Indices such as Platelet Volume, Platelet Distribution Width, and Plateletcrit Associated with Peyronie Disease?

        Cakir Suleyman Sami,Ozbir Sait,Atalay Hasan Anıl,Culha Mehmet Gokhan,Can Osman,Canat Halil Lütfi 대한남성과학회 2020 The World Journal of Men's Health Vol.38 No.3

        Purpose: Peyronie disease (PD) occurs as a result of recurrent microvascular injuries or trauma of the tunica albuginea, although its precise etiology is unknown. Mean platelet volume (MPV), platelet distribution width (PDW), and plateletcrit (PCT), which are parameters indicative of platelet activity, are considered to be functional markers of platelets involved in the pathophysiology of related inflammatory and vascular diseases. In this study, we aimed to examine the relationship between PD and platelet indices. Materials and Methods: We evaluated participants who presented to the andrology department of our institution between December 2015 and May 2018. Ninety-two men with PD and 80 healthy volunteers were included in this study. Participants who had received medical treatment affecting platelets or had any hematologic or systemic diseases were excluded from the study. Results: The mean age of men with PD was 53.8±10.2 years, and the mean age of the control group was 52.2±8.0 years (p=0.465). There were no significant differences in the mean IIEF-5 scores, platelet count, MPV, PDW, or PCT between the patients with and without PD (p<0.05). Conclusions: No correlations were found between PD and platelet indices. Large-scale prospective cross-sectional studies are needed to elucidate the etiopathogenesis of PD.

        Superoxide Anion Production by the Spermatozoa of Men with Varicocele: Relationship with Varicocele Grade and Semen Parameters

        İlter Alkan,Meral Yüksel,Halil Lütfi Canat,Hasan Anıl Atalay,Osman Can,Hakan Özveri,Mehmet Murad Başar 대한남성과학회 2018 The World Journal of Men's Health Vol.36 No.3

        Purpose: To investigate the pathophysiological role of superoxide anion and total reactive oxygen species (ROS) production by the spermatozoa of men with varicocele and its relationship with varicocele grade and semen parameters. Materials and Methods: This prospective study included 34 men with grade II–III varicocele, regardless of their fertility status. The control group consisted of 13 healthy men. Semen characteristics were examined according to the 2010 World Health Organization criteria. The swim-up method was used for sperm preparation. Total ROS and superoxide anion production was assayed by luminol- and lucigenin-dependent chemiluminescence (CL), respectively. Results: The men with varicocele had significantly higher total ROS and superoxide anion levels than the healthy control subjects (2.9±0.4 relative light unit (RLU) vs. 2.4±0.1 RLU, p=0.001 for luminol-dependent CL and 2.8±0.4 RLU vs. 2.3±0.2 RLU, p=0.002 for lucigenin-dependent CL). Cases of grade III varicocele had significantly higher superoxide anion and total ROS levels than grade II cases and control subjects (p<0.001). Superoxide anion and total ROS levels were negatively correlated with all semen parameters. Conclusions: The superoxide anion levels produced by spermatozoa were significantly higher in varicocele patients than in control subjects. ROS production was related to increased varicocele grade, impaired semen concentration, and abnormal morphology in men with varicocele. Our findings suggest that superoxide anion overproduction may be an important step in the cascade of ROS-related damage to spermatozoa, resulting in impaired semen parameters in patients with varicocele.
