SARS-CoV-2 which causes coronavirus disease 2019 (COVID-19) binds to angiotensin-converting enyzme 2 (ACE2) and enters the host cell. ACE2 protein is expressed highly in the testis. The aim of this study was to compare male reproductive hormones such as total testosterone (TT), luteinizing hormone (LH), follicular stimulant hormone (FSH), and prolactin between patients with COVID-19, age-matched cases with non-COVID-19 respiratory tract infection, and age-matched controls. This was a prospective cohort study and included 262 men aged between 20 and 65 years. The study comprised 3 groups including patients with COVID-19 (n = 89), cases with non-COVID-19 respiratory tract infection (n = 30), and age-matched controls (n = 143). All cases were evaluated using TT, LH, FSH, and prolactin. Correlations between TT and clinical parameters of patient groups were investigated using Pearson's correlation test. The primary outcome of the study was detection of the difference of TT, FSH, LH, and prolactin levels between the groups. Secondary outcome was to correlate TT and hospitalization time and oxygen saturation on hospital admission (SpO2) of patients. The mean age of study groups was 49.9 ± 12.5 years, 52.7 ± 9.6 years, and 50 ± 7.8 years, respectively (P = .06). Serum TT levels was median 185.52 ng/dL in patients with COVID-19, median 288.67 ng/dL in patients with non-COVID-19 respiratory tract infection and median 332 ng/dL in control cases, (P < .0001). The proportion of patients with testosterone deficiency in group 1, group 2, and group 3 was 74.2%, 53.3%, and 37.8%, respectively (P < .0001). Serum LH levels (P = 0.0003) and serum prolactin levels (P = .0007) were higher in patients with COVID-19 and patients with non-COVID-19 respiratory tract infection than control cases. Correlation analysis revealed significant negative correlation between serum TT levels and hospitalization time of patients with COVID-19 (r = -0.45, P < .0001). In addition, a significant positive correlation was observed between SpO2 and serum TT levels in patients with COVID-19 ( r = 0.32, P = .0028). Physicians may consider to evaluate male patients with COVID-19 for concomitant androgen deficiency. Strengths include the evidence about the alteration of male reproductive hormones under COVID-19. Limitations include the analysis limited to one general hospital, only a single measurement of TT was available, free and bioavailable testosterone levels were not evaluated. This study demonstrates COVID-19 is associated with decreased level of TT and increased level of LH and prolactin. More serious COVID-19 causes more reduction in TT levels and prolongs hospitalization period. Kadihasanoglu M, Aktas S, Yardimci E, et al.

Previous studies have evidenced that inflammation and endothelial dysfunction have a crucial role in erectile dysfunction (ED). Increased monocyte count or activity and lower high-density lipoprotein cholesterol (HDL-C) levels have been associated with inflammation. The monocyte to HDL-C ratio (MHR) is a recently emerged indicator of inflammation. We aimed to investigate the relationship between MHR and ED. In this retrospective study, a total of 120 patients were enrolled, 60 of them having ED and 60 having a normal erectile function. The presence of ED was evaluated with the International Index of Erectile Function (IIEF-5). Patients with ED were compared with the control group for IIEF-5 and MHR. The mean ages of patients and controls were 55.6±5.53 and 56.42±6.63 years, respectively (p = 0.47). The risk factors for ED were similar between cases and controls. The total testosterone, glucose and creatinine levels did not differ between groups. While the HDL-C, LDL-C and triglyceride levels were similar between groups, the monocyte count (0.55±0.20 vs. 0.73±0.18, p < 0.0001) and MHR was significantly greater in patients with ED than in those without ED (1.31 vs. 1.77, p < 0.0001). MHR was significantly negatively correlated with IIEF-5 (p < 0.0001). To our knowledge, this is the first study that has shown a significant and independent association between elevated MHR and ED.

The aim of this study was to evaluate the quality of life of patients with lifelong and acquired premature ejaculation and to examine its relationship with depression and anxiety. Between February 2017 and January 2018, a total of 175 patients with premature ejaculation and 132 control men who applied to the urology department of the training and research hospital with the complaint of Premature Ejaculation were included. Patients were divided into three groups according to International Society for Sexual Medicine (ISSM) criteria as follows: Group 1, lifelong premature ejaculation; Group 2, acquired premature ejaculation, and Group 3, control group without premature ejaculation. A detailed medical history of patients was obtained and physical examinations were performed. Intravaginal ejaculation latency time (IELT) was recorded and patients were administered International Erectile Function Index-5 (IIEF-5), Premature Ejaculation Diagnostic Tool (PEDT), Sexual Health Inventory for Men (SHIM), Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI)-1 and STAI-2, and Short Form-36 (SF-36). The mean mental component score (MCS) of the SF-36 was 51.65±6.57 in the lifelong premature ejaculation group, 49.33±8.65 in the acquired premature ejaculation group, and 61.12±11.09 in the control group (p<0.0001). The mean physical component score (PCS) was 50.99±7.43 in the lifelong premature ejaculation group, 48.32±11.58 in the acquired premature ejaculation group, and 55.17±8.10 in the control group (p<0.0001). Quality of life of premature ejaculation patients as assessed by SF-36 was lower in the subscales of physical functioning, general health perception, vitality, and role limitations due to emotional functioning, compared to the control group. Lifelong and acquired premature ejaculation patients deteriorate their quality of life: the deterioration in these patients’ quality of life also negatively affects their depression and anxiety states.
