ABSTRACT

【Objective】 To analyze the efficacy of scrotum cold compress combined with antibiotics on necrospermia patients with seminal tract infection. 【Methods】 We made a retrospective analysis of the patients who were confirmed as necrospermia by more than 2 times of semen examination and positive by sperm bacteria culture at the Andrology Department of our center from January 2019 to September 2022. The experiment group patients who were cured by scrotum cold compress combined with sensitive antibiotics and L-carnitine were divided into experiment group A (1 time/day) and experiment group B (2 times/day) according to the daily times of scrotum cold compress. Meanwhile, only sensitive antibiotics and L-carnitine were administered in the control group patients. We recorded the improvement of sperm parameters and the number of negative sperm bacterial cultures in different groups at 4 weeks, 8 weeks, and 12 weeks of treatment. 【Results】 A total of 145 patients were enrolled in the study. According to the principle of randomization, 49 patients in group A, 49 patients in group B, and 47 patients in the control group were enrolled. After 4 weeks of treatment, there was no significant difference between the experiment group and the control group in terms of abstinence time, the number of negative sperm bacterial cultures, semen pH, sperm ratio of forward motility, or the sperm survival rate (all P>0.05). In terms of the sperm survival rate, group B (53.1±14.1) was superior to group A (46.2±16.4) (P<0.05). In the results of the treatment at 8 weeks, the number of negative sperm bacterial cultures was significantly higher in the experiment group (74/98) than in the control group (26/47) (χ2=5.14, P<0.05). Sperm ratio of forward motility was higher in the experiment group (26.5±11.9) than in the control group (22.8±12.6). The experimental group (53.1±14.6) also had a significantly higher sperm survival rate than the control group (47.6±13.4) (P<0.05). However, the number of negative sperm bacterial cultures, sperm ratio of forward motility, and the sperm survival rate were lower in experiment group A (35/49, 25.5±10.3, 51.1±15.0) than in experiment group B (39/49, 27.5±13.2, 55.1±14.2), but there was no statistical difference between the two groups (all P>0.05). After 12 weeks of treatment, the number of negative sperm bacterial cultures in the experimental group (67/98) was significantly higher than that in the control group (21/47) (χ2=6.11, P<0.05). Sperm ratio of forward motility in the experiment group (30.9±11.2) was higher than that in the control group (24.7±13.4) (P<0.05). The experiment group (56.3±13.0) had a significantly higher sperm survival rate than the control group (46.7±12.0, P<0.01). However, in terms of the number of negative sperm bacterial cultures, sperm ratio of forward motility, and the sperm survival rate, there were no statistical differences between group A (31/49, 28.8±10.0, 55.9±12.7) and group B (36/49, 32.8±12.1, 56.7±13.4) (all P>0.05). 【Conclusion】 Scrotum cold compress combined with antibiotics is superior to only antibiotic treatment on necrospermia patients with seminal tract infection, especially in the sperm ratio of forward motility and sperm survival rate, but it has little relationship with the times of cold compressions per day. Therefore, the method deserves application in this type of patients’ diagnosis and treatment.
