Background: Bilateral synchronous testis germ cell tumors with different histopathology are not common. Case Presentation: Here, a case of 27-year-old male who is reported presented with bilateral testicular swellings. There was a high α-fetoprotein level with bilateral lesions on scrotal USG. Bilateral orchiectomy was performed. According to pathology report, there was a right testicular semi...

Spermatogenesis is a costly process that is expected to be under selection to maximise sperm quantity and quality. Testis size is often regarded as a proxy measure of sperm investment, implicitly overlooking the quantitative assessment of spermatogenesis. An enhanced understanding of testicular function, beyond testis size, may reveal further sexual traits involved in sperm quantity and quality...

Abstract Isotomus speciosus is a polyphagous insect that damages coniferous and deciduous trees. There no study on the male reproductive system of I. although it an important pest. For this purpose, anatomy histology were investigated using light scanning electron microscopy. According to results obtained, consists pair testes (each with separate testis lobes), two pairs vasa efferentia, defere...

BACKGROUND Nicotine consumption can decrease fertility drive in males by inducing oxidative stress and DNA damage. Urtica dioica L (U.dioica) is a multipurpose herb in traditional medicine for which some anti-oxidative and anti-inflammatory properties have been identified. OBJECTIVE The main goal is to investigate whether the U.dioica could inhibit nicotine adverse effects on sperm cells viab...

Cadmium (Cd) is one of the most toxic environmental heavy metals to organisms. The prominent toxic effects of Cd on reproductive organs are very well known. Gonad histopathology is a valuable tool for the assessment of endocrine disruption compounds EDCs effects on fish. The aim of this study was to evaluate the reproductive toxicity of cadmium chloride (CdCl2) on histopathology of Zebrafish (D...

Background: Methamphetamine (mAMP) as a recreational drug has devastating effects on the central nervous system (CNS). Several studies have shown that mAMP has inhibitory effects on oogenesis and spermatogenesis, and causes impaired fertility. This study designed to investigate the effect of mAM Padministration on histological changes and spermatogenesis indices in the testis of adult male rats...

It was found that a strain of deermice (Peromyscus maniculatus), which genetically lacks liver alcohol dehydrogenase activity also displays no such activity in the testis and is devoid of the enzyme activity that converts retinol to retinal, both in liver and in the testis; nevertheless, these animals exhibit normal reproduction and testicular histology. Therefore, one must reconsider the theor...

A case of seminoma of the testis complicated by an extensive granulomatous reaction is reported. This reaction was so florid that a benign condition was initially considered until further material for histology was examined and the correct diagnosis made.

Bilateral Testicular tumours are rare. A teratoma followed by a seminoma is one of the most uncommon forms of presentation. A case is described in a 29 year old soldier with a review of the literature and a discussion of the problems associated with diagnosis.
