Effect of chlorpyrifos on sperm characteristics and testicular tissue changes in adult male rats
Chlorpyrifos (CPF) is a broad spectrum organophosphate pesticide used for agricultural health purposes. Its principal mechanism of toxicity is the inhibition of acetylcholinesterase. The purpose of present study was to investigate the effects of CPF on testicular tissue and sperm parameters in male rats. Thirty-two healthy male rats were divided into two groups: a CPF-exposed group and a contro...
متن کاملTesticular sperm extraction: microdissection improves sperm yield with minimal tissue excision.
Testicular sperm extraction (TESE) is often an effective method for sperm retrieval from men with non-obstructive azoospermia. However, TESE has been a blind procedure that does not identify the focal sperm-producing areas of the testicle until after tissue has been excised from the patient. Experience with a new technique of microdissection of testicular tubules is presented here that identifi...
متن کاملAluminium-Induced Oxidative Stress, Apoptosis and Alterations in Testicular Tissue and Sperm Quality in Wistar Rats: Ameliorative Effects of Curcumin
Objective Reproductive toxicity is a major challenge associated with aluminum (Al) exposure. No studies have evaluated the possible effects of curcumin (CUR) on Al-induced reproductive dysfunction. Therefore, this study investigated the effects of CUR treatment on Al-induced reproductive damage. MaterialsAndMethods In this experimental study, 40 male Wistar rats were allocated to five groups (N...
متن کاملبررسی میزان بیان آنزیم دایسر در نواحی in situ carcinoma در مقایسه با مناطق in vasive carcinoma در سرطان پستان
خلاصه : کارسینوم تهاجمی سینه پستان علت مرگ و میر حاصل از سرطان خانم ها در بسیاری از کشورها می باشد. این کارسینوم بدنبال کارسینوم در محل ایجاد می شود. در کارسینوم در محل سلول های توموری هنوز نتوانسته اند که از غشاء پایه عبور کنند. در عبور از مرحله کارسینوم در محل به مرحله تهاجمی، سلولهای سرطانی تغییرات مولکولی بسیاری پیدا میکنند که هنوز علت عده ای از آنها مشخص نشده است. در این مطالعه ما بررسی کر...
15 صفحه اولTissue perfusion-controlled guided biopsies are essential for the outcome of testicular sperm extraction.
OBJECTIVE To determine if there are areas of major and minor perfusion in a single testicle, and if the quality and quantity of sperm are correlated with the level of perfusion, we collected testicular tissue from areas with different levels of perfusion. DESIGN Controlled clinical study. SETTING Consecutive patients with azoospermia. PATIENT(S) Patients with azoospermia undergoing testic...
