In spite of prompt diagnosis and either orchiectomy or preservation of the affected testis, infertility remains a significant sequel to testicular torsion. The objective of this study was to evaluate the late endocrine profile, seminal parameters, and antisperm antibody levels after testicular torsion. We also analyzed the impact of orchiectomy or detorsion on the organ fate. Of 24 patients evaluated after testicular torsion, 15 were treated with orchiectomy (group 1) and 9 were treated with orchiopexy (group 2). All subjects were assessed by semen analysis, endocrine profile (levels of follicle‐stimulating hormone, luteinizing hormone, and testosterone), and seminal antisperm antibody levels. A group of 20 proven fertile men was used as the control. Median ischemia time in group 1 (48 hours) was significantly higher than in group 2 (7 hours). Both groups demonstrated decreases in sperm count and morphology compared with controls. Group 1 showed a significantly higher motility than group 2 (P = .02). Group 1 also showed a significantly better morphology by World Health Organization and Kruger criteria than group 2 (P = .01). All patients presented endocrine profiles within the normal range, and no significant differences in antisperm antibody levels were detected between the groups. However, a trend for higher levels was found in patients treated for testicular torsion, regardless of the fate of the testis. Moreover, no significant correlation was found between antisperm antibody levels and age at torsion, ischemia time, seminal parameters, or treatment applied. In conclusion, we found that after torsion patients maintain late hormonal levels within the normal range. Testicular fate did not have any correlation with the formation of antisperm antibodies. Although sperm quality was preserved in most of the patients with the exception of sperm morphology, patients treated with orchiectomy presented better motility and morphology compared with the detorsion group. Further studies may clarify whether maintenance of a severely ischemic testicle may impair testicular function.

Although reactive oxygen species (ROSs) are clearly implicated in the pathogenesis of male infertility, few studies have attempted to define the basal levels of ROSs in fertile men. Levels of ROSs are highly influenced by the presence of leukocytes and are associated with decreased seminal parameters. The objective of our study was to determine the normal ROS reference values in neat and washed semen of a fertile population and to correlate the leukocyte concentrations with seminal parameters. We evaluated 114 fertile men seeking vasectomy and 47 subfertile patients as a positive control. All samples were subjected to semen analysis and Endtz testing; chemiluminescence assay was used to determine ROS levels. All seminal parameters were significantly higher in the fertile men than in the subfertile patients. In nonleukocytospermic samples, ROS levels were lower in the fertile men than in the subfertile patients in neat (0.29 [0.18, 0.54] vs 0.94 [0.38, 1.51]) (P = .001) and washed semen (5.73 [1.90, 14.71] vs 23.4 [9.46, 115.55]) (P = .001). Similarly, in samples with leukocytes (Entdz, less than 1 × 10⁶/mL), ROS levels were lower in the fertile men in neat (0.75 [0.27, 1.71] vs 2.0 [0.97, 27.41]) (P = .001) and washed semen (15.85 [4.18, 62.16] vs 239.83 [33.4, 1193.75]) (P < .0001). As expected, samples with leukocytes had significantly higher ROS values in washed and neat semen. In the fertile population, ROSs were positively correlated with leukocytes and negatively correlated with sperm count and motility. In semen samples without leukocytes, the normality cutoff of ROSs was 0.55 × 10⁴ counted photons per minute with 76.4% area under the curve (AUC) in the neat samples and 10.0 × 10⁴ counted photons per minute with 77% AUC in the washed samples. In semen samples with leukocytes, the cutoff for ROSs in neat samples was 1.25 with 72.7% AUC and 51.5 with 81% AUC in the washed samples. We defined the cutoff levels of ROSs in a fertile population. Seminal leukocyte levels below 1 × 10⁶/mL were associated with increased ROSs. ROS levels were positively correlated with leukocytes and negatively correlated with sperm motility and concentration. Patients with normal seminal parameters and lower seminal leukocyte levels may benefit from therapeutic interventions that improve semen quality.

Objective: To assess gonad function in male patients with systemic lupus erythematosus (SLE).Methods: Thirty‐five consecutive male patients with SLE according to the criteria of the American College of Rheumatology were prospectively evaluated for demographic and clinical features as well as previous and current treatment. Patients underwent urologic evaluation and testicular Doppler ultrasound. We obtained a hormone profile and performed a semen analysis including morphology and testing for the presence of antisperm antibodies. Patients were compared with 35 age‐matched healthy controls.Results: Compared with controls, SLE patients had lower median testicular volumes in both testes, a lower median total sperm count, and a lower median total motile sperm count. The mean sperm volume and percentage of normally formed sperm were lower in SLE patients than in controls. Since all SLE patients had semen alterations, they were further subdivided into 2 groups according to the severity of these abnormalities (group 1, with teratozoospermia [n = 18], and group 2, with azoospermia or teratozoospermia in combination with oligozoospermia and/or asthenozoospermia [n = 17]). The frequency of treatment with intravenous cyclophosphamide (IV CYC) after the first ejaculation was higher in group 2 than in group 1. The median testicular volumes measured by ultrasound in both testicles were lower in group 2 than in group 1. Follicle‐stimulating hormone levels were higher in group 2 than in group 1. The overall frequency of antisperm antibodies in SLE patients was 40%. The apparent higher frequency of antisperm antibodies in group 1 than in group 2 did not reach significance.Conclusion: SLE patients have a high frequency of sperm abnormalities associated with reduced testicular volume. Postpubertal IV CYC treatment was the major factor in potential permanent damage to the testes.
