Cellular junctions of the lining epithelium of the efferent ductules of the mouse, guinea pig, and human testes were examined by freeze-fracture. A belt-like gap juncion consists of a large aggregation of particles with a few fragments of the tight junctional strands and circumferentially occupies the adluminal area between the nonciliated cells. This type of gap junction appears to be one of t...

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...

Abstract Background Undescended testis is one of the most common paediatric surgical diagnoses. A lot research has been done to date, standardise management intra-abdominal and extra-abdominal undescended testis. High inguinal a unique clinical encounter which demands additional measures over conventional orchidopexy for better results. Main body abstract Open routine quite straightforward oper...

By M. N. S. CHETTI, i.u. & s., Civil Surgeon, Sagaing. A Burman male aged 47 years was brought to the hospital on 1st April, 1925, with a history of enlargement of the right testicle with swelling about 9 clays ago without any cause. On examination the tumour was found to be somewhat about the shape and size of a mediumsized mango extending above the external ring. The upper one-third was soft ...

History.? The patient noticed enlargement of the left testicle while he was 13 years old ; it was quite pain'ess then. After a year he also noticed slight enlargement of the other testicle, but he cannot state when the thickening of his scrotum commenced. Within these two years his scrotum assumed the size of a child's head, and continued so till the 45ih year of his age. During the last nine y...

The gonadal development of the Macaca fascicularis fetus was studied between 37 and 118 days on serial semi-thin and thin sections. The testis and the ovary began to differentiate at the same age (37 days); the definitive architecture of the testis was acquired at 43 days, while a cortex and a medulla did not form in the ovary until 55 to 60 days. In spite of the time-lag and the divergent deve...

The aim of the present study was to determine how often spermiogenesis occurs in young male European bison up to 3 years old. Research was performed on sections of the testes and epididymes collected from 51 male bison aged 2-3 years. The animals were divided into 2 age groups: young males up to 2 years and young males up to 3 years old, with further separation into specimens with or without sp...

Triorchidism is the commonest variety of polyorchidism, an entity with more than two testis is an extremely rare congenital anomaly of the testis. Although excision of the abnormal testis is a safer alternative proposed, recent literature suggests more conservative approach in normal testes with watchful regular follow up to screen for malignancy. This case presented as a left inguinal swelling...

This study was designed to determine the testicular abnormalities in rams slaughtered Sokoto, Nigeria. The testicles of presented for slaughter were examined, and age, breed, position, sites noted. Out 638 3 had abnormalities, representing a prevalence 0.47%, comprising 2 (0.31%) unilateral cryptorchidism 1 (0.16%) hypoplasia. (0.58% (2/342) 0.34% (1/296) obtained at Sokoto metropolitan abattoi...

L-myo-Inositol-1-phosphate synthase (EC 5.5.1.4) has been purified to homogeneity for the first time and its properties were investigated. By means of ammonium sulfate precipitation from rat testis supernatant, followed by chromatography on DEAE-cellulose, Ultrogel, glucose 6-phosphate-Sepharose, and hydroxylapatite, the synthase was purified 460-fold to a specific activity of 250 milliunits/mg...
