Abstract

Background: Many azoospermic patients with non obstructive azoospermia (NOA) are candidate for testicular sperm extraction (TESE) and in vitro fertilization. Because sperm might be present in some but not all parts of the testes of such men, multiple sampling of testicular tissue are usually necessary to increase the probability of sperm finding. Sperm finding can be done by two methods: 1) classic histopathology and 2) wet smear.
Objective: Comparative study of pathology and wet smear methods for discovering sperm in testis biopsy of azoospermic men.
Materials and Methods: We prospectively studied 67 consecutive infertile men who referred to Fatemieh Hospital, Hamedan, Iran between April 2002 and September 2004. All patients were either azoospermic or severely oligozoospermic. They underwent intraoperative wet prep cytological examinations of testis biopsy material and then specimens were permanently fixed for pathologic examination too.
Results: Among the 67 testes that underwent wet prep cytological examination, 44 (65.7%) were positive and 23 (34.3%) had no sperm in their wet smear. On the permanent pathologic sections, 19 (28.4%) were positive and 48 (71.6%) cases were with no sperm in their sections. Among all the individuals 18 (26.8%) were negative in both studies, while 14 (20.8%) had minimum 1 sperm in their smears in both examinations. The positive cases in wet prep cytological examination were significantly more than the cases in the permanent histopathologic sections (p-value=0.000).
Conclusion: It seems that wet prep cytological examination is more reliable than permanent histopathologic sections in detecting sperm in testis biopsy of azoospermic men.

Abstract

Background: Diabetes is the most common endocrine disease. It has adverse effects on male reproductive function. Royal Jelly (RJ) has antioxidant and anti-diabetic effects and show protective effects against diabetes.
Objective: This study was conducted to evaluate the effect of RJ on histopathological alterations of the testicular tissue in streptozotocin (STZ)-induced diabetic rats.
Materials and Methods: In this experimental study, 28 adult Wistar rats were randomly divided into control (C), royal jelly (R), diabetic (D) and RJ-treated diabetic (D+R) groups. Diabetes was induced by a single intraperitoneal injection of STZ at 50 mg/kg body weight (BW). The rats from the R and D+R groups received daily RJ (100 mg/kg BW) for 6 wks orally. Hematoxylin-Eosin staining was used to analyze histopathological changes including: tunica albuginea thickness (TAT), seminiferous tubules diameter (STsD), Johnsen’s score, tubular differentiation index (TDI), spermiogenesis index (SPI), Sertoli cell index (SCI), meiotic index (MI), and mononuclear immune cells (MICs) in testes. The antioxidant status was examined by evaluating testicular levels of ferric reducing antioxidant power (FRAP) and catalase (CAT) activity.
Results: Histological results of the testis from diabetic rats showed significant decrease in STsD, Johnsen’s score, TDI, SPI, SCI and MI, and significant increase in TAT and MICs, while administration of RJ significantly reverted these changes (p<0.05). RJ treatment markedly increased activity of CAT and FRAP. There were significant differences in FRAP levels among C (13.0±0.5), RJ (13.4±0.3), D (7.8±0.6) and D+R (12.4±0.7) groups (p<0.05).
Conclusion: RJ improved diabetes-induced impairment in testis, probably through its antioxidant property.

Abstract

Background: Valproic acid (VPA), an anti-epileptic drug, can cause male subfertility. However, the degree to which testicular and epididymal histopathologies and androgen receptor (AR) expression are changed under VPA treatment has never been reported.
Objective: To investigate the histopathological changes and AR protein levels of testis and epididymis in VPA-treated rats for every single day.
Materials and Methods: Sixty-four adult male Wistar rats were divided intocontrol and VPA-treated groups (n=8/ each). Treated rats were injected with 500mg/ kgBW, intraperitoneally, VPA for 10 consecutive days. At the end of everyexperimental day, all reproductive parameters including histology by hematoxylinand eosin staining and protein expression of AR by Immuno-Western blot in testisand epididymis were examined.
Results: VPA-treated rats showed dramatically changes in testicular and epididymal histopathologies compared to control group. The multinucleated giant cells and sloughing of germ cells were observed on day 6. The germ cell disintegration and increased intercellular spaces of seminiferous tubular epithelium appeared in days 7-10 of VPA treatment. Additionally, extensive multinucleated giant cells and complete exfoliation were clearly found from days 8-10. Such exfoliated germ cells were clearly seen in its epididymal lumen at day 10. The increasing rate of sperm concentration was approximately 32.31% of that in control group at day 10 (p=0.03). Moreover, the protein expressions of testicular and epididymal AR (% intensity/ 80 μg protein lysate) was decreased in VPA-treated rats compared with control.
Conclusion: VPA treatment induces histologic changes of germ cell epithelium in seminiferous tubules and decreases the expression of testicular and epididymal

Abstract

Background: Tamsulosin is an inhibitory factor of alpha-adrenergic receptors that is used for relieving of the clinical symptoms and management of acute urinary retention.
Objective: The aim of this study was to evaluate the effects of tamsulosin on the endocrine axis and testicular tissue in adult male rats.
Materials and Methods: In this experimental study, 30 adult male Wistar rats (weighing 250-300 gr) were divided into three groups: 1) control (received distilled water), 2) experimental 1 (received 0.2 mg/kg/day tamsulosin) and 3) experimental 2 (received 0.4 mg/kg/day tamsulosin) through oral gavage for 28 days. Serum hormones level and testicular histopathology were evaluated at the end of the experiment.
Results: In this study, the testicular weight decreased significantly in the experimental groups compared to the control group. A significant decrease was seen in testicular weight (p = 0.004) and the number of Leydig cells in tamsulosin-treated groups (p = 0.012). Tamsulosin improved the hormone profile in experimental groups. Also, higher dose of tamsulosin significantly changed the number of Leydig, spermatogonia cells, the thickness of germinal layer, and the diameter of the seminiferous tubules.
Conclusion: Results showed that using tamsulosin, possibly reduces the testosterone concentration through adrenergic axis system and in turn has destructive effects on proliferative activity of germ cells.
