A preterm (36 week) neonate, presented with his left testicle hanging outside through the inguinal canal. The testicle was pexed in a sub-dartos pouch.

This study considers a unilateral renal agenesia associated with agenesia of the epididymis body and tail and the vas deferens and non-palpable left testicle in a 20-month-year-old patient. During laparoscopic procedure, the testicle was positioned at approximately 5 cm above the inguinal ring. The size was appropriate for the age and the head of the epididymis was situated in its normal positi...

background: given the paucity of data on possible testis changes in opioid dependents, we sought to compare the testis volumes between a group of opium dependents and a group of healthy controls. objective: comparison of testis volume between opium dependents and healthy controls. materials and methods: this case-control study recruited 100 men with opium dependency (cases) and 100 healthy men ...

At the onset of puberty, seminiferous tubules rapidly increase in diameter, thereby occupying a greater proportion of the testis, resulting in a rapid increase in testicular size. The objective of the current studies was to evaluate ultrasonography for assessing testicular diameter, as a basis for ranking boars relative to their extent of pubertal development. In the initial study, prior to cas...

Fibroblast growth factors (FGFs) are classically known as hormonal factors and recent studies have revealed that FGFs have a key role in regulating growth and development of several reproductive organs, including the testis. The testis is mainly consisted of germ cells, Sertoli cells and Leydig cells to develop and maintain the male phenotype and reproduction. This review summarizes the structu...

AIM To identify and characterize a novel gene with potential roles in testis development and spermatogenesis. METHODS A cDNA microarray was constructed from a human testis large insert cDNA library and hybridized with probes of human or mouse adult and fetal testes. Differentially expressed genes were isolated and sequenced. RT-PCR was used to test the tissue distribution of the genes of inte...

This study was designed to investigate whether administration of zinc sulphate could improve theresponse of mouse testis to degenerative effects of short term exposure heating. Fifty-four adult male Balb/Cmice were anaesthetized and the scrotums of 36 of them were immersed for 15 min in a waterbath at 43°C.Immediately after the heating, half of the heated animals (n = 18) were injected with sal...

Background The present study describes the susceptibility of prepubertal testis of mice to prooxidant induced oxidative impairments both under in vitro and in vivo exposure conditions. MaterialsAndMethods Following in vitro exposure to iron (5,10 and 25 M), oxidative response measured in terms of lipid peroxidation and hydroperoxide levels in testis of pre pubertal mice (4 wk) was more robust c...
