The Relationship of Testicular Sonoelastography with Gonadotropin Hormone Levels and Sperm Parameters

Abstract

Background: Elastography is a non-invasive medical imaging technique that helps determine the stiffness of organs and other structures in our body. In this study, we investigated the effectiveness of elastography in the diagnosis of infertility. Aim: In this study, we aimed to examine the relationship between testicular elastography and hormonal parameters and sperm parameters. Patients and Methods: The study included 136 patients, 272 testicles were examined, and the mean age of the study participants was 30.1 years. Testicular tissue stiffness was measured by scrotal ultrasonographic shear wave elastography. Gonadotropin and testosterone hormones were measured from blood samples. Spermiogram parameters were studied manually. Results: The control group included 66 patients, and the varicocele group consisted of 70 patients. Testicular stiffness degrees of the control group were measured as 4.29 kPa for the right testis and 4.23 kPa for the left testis. The varicocele group was divided into grades 1, 2, and 3 according to physical examination. In group 1 (grade 1), the right testis was 4.07 ± 1.24 kPa and the left testis was 3.77 ± 0.98 kPa. In group 2 (grade 2), the right testis was 4.31 ± 1.40 kPa and the left testis was 3.98 ± 0.93 kPa. In group 3 (grade 3), the right testis was 4.73 ± 1.50 kPa and the left testis was 3.99 ± 1.68 kPa. Hormone and sperm parameters were not statistically significant when comparing the control and varicocele groups. There was no statistical significance between the testicular tissue stiffness degrees of the control and varicocele groups. Hormone and spermiogram findings were also similar in groups. Conclusion: It is known that varicocele leads to histological tissue changes in the testes. These changes result in tissue softness and loss while affecting sperm parameters and testosterone levels in a negative way. Before varicocele surgery, there is a need for new imaging methods with more sensitivity that can detect tissue changes in the testes.
