BACKGROUND In numerous Caudata, the testis is known to differentiate new lobes at adulthood, leading to a multiple testis. The Iberian ribbed newt Pleurodeles waltl has been studied extensively as a model for sex determination and differentiation. However, the evolution of its testis after metamorphosis is poorly documented. METHODS Testes were obtained from Pleurodeles waltl of different age...

Earlier in our laboratory, sperm immobilization factor (SIF) isolated from Escherichia coli has shown admirable contraceptive efficacy female mice and thus generated interest evaluating the same as a potential candidate for male contraception. Keeping this mind, present study was aimed at exploitation of SIF agent mouse model after intra testis administration. For this, Balb/c were administered...

Controversies and debates still prevail in current literature concerning the role of bacterial infection male infertility. A handful studies have discovered a correlation between bacteria azoospermia condition which discharge is utterly devoid spermatozoa. In line with this, present study was designed to evaluate influence Escherichia coli on spermatogenesis. single dose (108 cfu/20ul) uropatho...

OBJECTIVE To study the outcomes of microdissection testicular sperm extraction (microTESE) among men with pure Sertoli cell-only histology on diagnostic testicular biopsy. DESIGN Retrospective cohort study. SETTING Tertiary referral center. PATIENT(S) Six hundred forty patients with pure Sertoli cell-only histology on testicular biopsy who underwent microTESE by a single surgeon. INTERV...

Quantitative histology of the descended testis of unilateral cryptorchid bucks was compared with testis of normal bucks to evaluate the reproductive potentials of the scrotal testis in unilateral cryptorchids, using light microscopy techniques. The contralateral scrotal testes of the unilateral cryptorchids and the testes of the normal bucks contained profiles of seminiferous epithelium and eac...

PURPOSE We evaluated the clinical and therapeutic characteristics of adult cryptorchidism, which have been difficult to establish, given the small number of patients presenting to outpatient clinics. MATERIALS AND METHODS A retrospective study of 20 adult patients with cryptorchid testis was performed. We analyzed their palpation of testis, location, surgical method, marital status, number of...

Background: Carbon tetrachloride (CCl4), an industrial solvent, is a well-established hepatotoxin. Studies demonstrated that liver is not the only target organ of CCl4 since it causes free radical generation in other tissues such as testis. It has also been reported that exposure to CCl4 induces acute and chronic reproductive toxicity. Diverse medicinal plants have been screened and assessed fo...

Introduction: Our aim was to evaluate effects of hemicastration in immature rabbits on the histology of the contralateral testis after puberty. Materials and Methods: Eighteen immature male rabbits were randomly divided into two groups. The first group underwent right or left hemicastration and the second, sham operation. After their puberty, the rabbits underwent the second operation. In the f...

The histology and histochemistry of the testis guinea pig various postnatal age groups was conducted. A total 24 pigs four different ages with six male animals each were collected from Department Laboratory Animal Medicine, Madhavaram Milk Colony, Chennai as per Ethical committee approval. After collection, euthanized CPCSEA norms dissected out cut into small pieces, fixed processed for paraffi...

A nineteen year old Kenyan male presented with a twelve month history of rapidly progressing painless swelling of both testicles. Pre-operative clinical and laboratory evaluation resulted in clinical suspicion of bilateral testicular tumour confirmed by ultrasonography. Bilateral inguinal orchidectomy was effected and histology confirmed bilateral primary malignant lymphoma of the testis in a n...
