The results of manual dissection of the musculature of the male genitalia in are fully confirmed by the modern methods of Micro-CT. A comparative analysis of and sp. shows that an increase in the flexion in the genitalia of males and the displacement of syntergosternite VII to the ventral side in sp. caused the disappearance of the muscles ITM6-7r and ITM7-8r. In addition, this increase in flexion apparently caused the fusion of the M18 muscles into one bundle. The muscle ISM5-6c goes on to moving the second segment of the forcipate appendages of sternite V.

Libido plays a crucial role in influencing semen quality, yet the underlying regulatory mechanisms remain unclear. As a central axis in male goose reproduction, the hypothalamic-pituitary-testicular-external genitalia (HPTE) axis may contribute to the regulation of this process. In this study, we established a rating scale for goose libido based on average number of massages to erection (ANM) and the erection type, and evaluated semen quality across the entire flock.

Purpose To determine which quantitative 3-T multiparametric MRI (mpMRI) parameters correlate with and help predict the presence of aggressive large cribriform pattern (LCP) and intraductal carcinoma (IDC) prostate cancer (PCa) at whole-mount histopathology (WMHP). Materials and Methods This retrospective study included 130 patients (mean age ± SD, 62.6 years ± 7.

Department of Urology, Holmesglen Private Hospital, Moorabbin 3189, Victoria, Australia.
Background: The penile suspensory ligament (PSL) plays a significant role in penile support and erection and its injury or congenital absence may result in functional impairment of erectile function.
Aim: To describe the diagnosis and surgical repair technique for PSL abnormalities and overall outcomes.
Methods: A comprehensive review of the literature was performed to understand the anatomic relevance of the PSL and historical management of PSL defects.

Background: Tramadol, an opioid analgesic, is known to induce testicular damage and impair reproductive parameters. Vitamin D3, recognized for its antioxidant and protective properties, might offer a potential protective effect against tramadol-induced testicular damage. This study observed the effects of co-administration of vitamin D3 and tramadol on serum kisspeptin levels, testicular histology, semen parameters, testosterone levels, and oxidative stress markers in male rats.

Department of Sports Science, College of Education, Zhejiang University, 310058 Hangzhou, Zhejiang, China.
Background: Testicular torsion-detorsion damage is a common ischemia-reperfusion injury brought on by an excess of reactive oxygen species. Reactive oxygen species may affect cellular differentiation by regulating gene expression. The gene expression in the testis is essential for spermatogenesis.
