BACKGROUND Queen conch (Strombus gigas) reproduction is inhibited in nearshore areas of the Florida Keys, relative to the offshore environment where conchs reproduce successfully. Nearshore reproductive failure is possibly a result of exposure to environmental factors, including heavy metals, which are likely to accumulate close to shore. Metals such as Cu and Zn are detrimental to reproduction...

introduction: cyclophosphamide (cp) is used for the treatment of various cancers. in spite of its therapeutic importance, a wide range of adverse effects such as reproductive toxicity has been observed following the administration of this drug in human and experimental animals. in the current study, we have investigated the adverse effects of cp on morphology and histology of testis rats. metho...

The purpose of this study was to characterize testicular development in D'Man ram lambs, focusing primarily on androgen receptors (ARs) immunolocalization in the adenohypophysis and testis that is not still known in the D'Man ram lamb. Lambs (n = 12) were divided into four groups (three lambs per group). Adenohypophysis and testis were fixed and paraffin embedded; cross-section (3 μm) were stai...

A 40-year-old male presented to our outpatient department with the chief complaint of a painless mass on his right testis with gradual size increase over the past two months. Physical examination and ultrasound revealed a firm and nontender mass both on the right and on the left testis. The only elevated biomarker was b-hcG (24,7 mIU/mL) and computer tomography (CT) did not reveal any pathology...

OBJECTIVE To examine effects of nondescent of normal testis and of various orchidopexy techniques on antisperm antibody (ASA) production and histologic testicular lesions. DESIGN Experimental cohort study. SETTING Laboratories of surgical research and biology of reproduction, academic medical centers. PATIENT(S) Lewis rats, immature and adult. INTERVENTION(S) Eighteen-day-old rats (6 gr...

background: there is a rapidly growing trend in the consumption of herbal remedies in the developing countries. the phoenix dactylifera date palm pollen (dpp) is used in the traditional medicine for male infertility. the aim of this study was to determine the effects of orally administered dpp on the reproductive system of adult male rats.   methods: fifty sprague-dawley rats were maintained ac...

Granulosa cell tumours are extremely rare and very few cases of adult type have been reported till date . can broadly classified into juvenile types. They known to occur more commonly occurs in females (in ovaries) than males testis) We here a case 39 year old man who was diagnosed with testicular granulose tumour no metastasis A High Inguinal radical Orchidectomy performed histology demonstrat...

Unlike other histology analysis, classification of tubule status in testis histology is very challenging due to their high similarity of texture and shape. Traditional deep learning networks have difficulties to capture nuance details among different tubule categories. In this paper, we propose a novel deep learning architecture for feature learning, image classification, and image reconstructi...

background: the predominant phytoestrogen in soy and derived products is the isoflavone genistein. genistein has antioxidant properties. morphine is a main psychoactive chemical in opium that can increase the generation of free radicals and therefore it could adversely affects the spermatogenesis. objective: the main goal was to investigate whether the genistein could protect morphine adverse e...
