Purpose: To investigate the effects of polypropylene mesh, implanted by inguinotomy, in the spermatic funiculus, epididium and testis of dogs. Methods: Eighteen dogs were considered (12-23 Kg), separated in three groups. Group A (n=7): left side (with mesh) versus right side (without mesh); Group B (n=7): left side (without mesh) versus right side (with mesh) and Group C (n=4): without any surg...

BACKGROUND Experimental rat varicocele was usually developed by the conventional technique but with varied success; and microsurgical rat varicocele model was an effective alternative. In this study we further analyzed differential outcome of experimental rat model with and without microsurgery. METHODS One hundred and twenty male Sprague-Dawley rats were randomly assigned to two groups. In G...

BACKGROUND Indirect inguinal hernias are usually congenital, forming a sac in the core of the spermatic cord covered by the internal spermatic, cremasteric, and external spermatic fasciae(1-3). Direct inguinal hernias are acquired; the sac lies beside/behind the cord(1-3). A rare third type is a combination of indirect and direct sacs on both sides of inferior epigastric vessels(1-3). We descri...

The aims of this study were to identify which aspects of castration are painful to piglets, and to determine if less painful methods are available. Previous work has shown that piglets produce more high frequency calls (>1kHz) when castrated than when handled identically but not castrated, or when castrated using a local anesthetic. In Experiment 1, we used 90 piglets to assess the vocal respon...

The role of the human testis in the production of 17beta-estradiol (E(2)) was investigated by determining the concentration of E(2) and testosterone in peripheral and spermatic vein plasma samples. Specimens were obtained from eight normal men, three men with hypogonadism, and two patients with the incomplete form of the feminizing testes syndrome. For comparison, similar studies were performed...
