  • Sonography of the Scrotum
    1 Sonography of the Scrotum Chee-Wai Mak and Wen-Sheng Tzeng Department of Medical Imaging, Chi Mei Medical Center, Tainan, Taiwan Central Taiwan University of Science and Technology, Taichung, Taiwan Chung Hwa University of Medical Technology, Tainan, Taiwan Republic of China 1. Introduction Although the development of new imaging modality such as computerized tomography and magnetic resonance imaging have open a new era for medical imaging, high resolution sonography remains as the initial imaging modality of choice for evaluation of scrotal disease. Many of the disease processes, such as testicular torsion, epididymo-orchitis, and intratesticular tumor, produce the common symptom of pain at presentation, and differentiation of these conditions and disorders is important for determining the appropriate treatment. High resolution ultrasound helps in better characterize some of the intrascrotal lesions, and suggest a more specific diagnosis, resulting in more appropriate treatments and avoiding unnecessary operation for some of the diseases. 2. Imaging technique For any scrotal examination, thorough palpation of the scrotal contents and history taking should precede the sonographic examination. Patients are usually examined in the supine position with a towel draped over his thighs to support the scrotum. Warm gel should always be used because cold gel can elicit a cremasteric response resulting in thickening of the scrotal wall; hence a thorough examination is difficult to be performed. A high resolution, near-focused, linear array transducer with a frequency of 7.5 MHz or greater is often used because it provides increased resolutions of the scrotal contents. Images of both scrotum and bilateral inguinal regions are obtained in both transverse and longitudinal planes.

This miracle is a characteristic that all living things have in common and sets them apart from nonliving things. But even though the reproductive system is essential to keeping a species alive, it is not essential to keeping an individual alive. In human reproduction, two kinds of sex cells or gametes are involved. Sperm, the male gamete, and an egg or ovum, the female gamete must meet in the female reproductive system to create a new individual. For reproduction to occur, both the female and male reproductive systems are essential. While both the female and male reproductive systems are involved with producing, nourishing and transporting either the egg or sperm, they are different in shape and structure. The male has reproductive organs, or genitals, that are both inside and outside the pelvis, while the female has reproductive organs entirely within the pelvis. The male reproductive system consists of the testes and a series of ducts and glands. Sperm are produced in the testes and are transported through the reproductive ducts. These ducts include the epididymis, ductus deferens, ejaculatory duct and urethra. The reproductive glands produce secretions that become part of semen, the fluid that is ejaculated from the urethra. These glands include the seminal vesicles, prostate gland, and bulbourethral glands.

    ACTA THERIOLOGICA VOL. 18, 5: 107—118 BIALOWIE2A April, 1973 Alina KOWALSKA-DYRCZ The Structure of Internal Genital Organs in Zapodidae (Rodentia) |With Plates I & II] Investigations were carried out of histological structure of internal genital organs in four species of Zapodidae. The chief differences have been stated in the structure of gl. coagulantes, gl. bulbo-urethrales, colliculus seminalis, bulbus penis and farther part of the pars spongiosa urethrae in Sicistinae (Sicista) and in Zapodinae (Zapus, Napaeozapus). On the other hand, the structure of reproductive system in Zapodidae (especially in Sicista) is similar to that in Muroidea, this resemblance being particularly distinct in the structure and arrangement of the vesi- culae seminales, gl. coagulantes, gl. prostaticae and even in gl. bulbo- -urethrales. The similarities in the reproductive systems of Zapodidae, Dipodidae, Muroidea and Sciuridae have been discussed. I. INTRODUCTION Philogenetical relationships among rodents are not clear and disputable in many points. Therefore many authors are trying to improve the syste- matics of this group basing it on the structure of some internal organs. These should be the so-called conservative organs which are little de- pendent on the environmental selection. The reproductive system is undoubtly such a one. The attempts to base the systematics of rodents on the structure of the male genital organs have, among others, been undertaken by Vinogradov (1925), Mossman et al. (1932), Ara- t a (1964). The present paper discusses the structure of the male repro- ductive organs in some representatives of the family Zapodidae (superfa- mily Dipodoidea). [1071 108 A. Kowalska-Dyrcz II. MATERIAL AND METHODS The material used for the investigations consisted of genital organs taken from: five sexually mature males of Sicista betulina (Pallas, 1778), two males of Zapus hudsonicus (Z immerman n, 1780), two males of Zapus princeps J.

  • The Development of the Intratesticular Excurrent Duct
    Histology, Cytology and Embryology (HCE) Research Article ISSN: 2514-5940 The development of the intratesticular excurrent duct system of donkey (Equus asinus) from birth to maturity Abd-Elhafeez HH*, Moustafa MNK, Zayed AE and Sayed R Department of Anatomy and Histology, Assuit University, Egypt Abstract The testis of the donkey was completely descended into the scrotum around birth. It was covered by a thick tunica albuginea consisting of outer and inner fibrous layers in addition to middle vascular one. Discrete bundles of smooth muscle cells were demonstrated in the outer fibrous layer of the tunica albuginea. These cells give the tunica albuginea a contractile function, which may aid in sperm transport. The present study emphasized an irregular arrangement of the testicular lobules of the donkey during various stages of the postnatal life. Such arrangement does not allow some lobules to have direct contact with the mediastinum testis. The latter was located paraxially, toward the epididymal border and extended about two-thirds of the testicular length; it is thick at the head extremity and gradually faded out caudal wards. The connection between the seminiferous cords and the initial part of the straight tubules exhibited a sharp cut contact in neonates, but it demonstrated exfoliated supporting and germ cells, as well as crowded population of peritubular cells in suckling animals. In premature ones, the connection between the seminiferous tubules and straight testicular tubules was characterized by a peculiar structure appearance that attained more modification and development. This connection included two regions; terminal segment of the seminiferous tubule and a dilated initial part of the straight tubule.

  • Fluid on the Germinal Epithelium in the Rat Lynn M
    Effects of obstruction of the flow of seminiferous tubule fluid on the germinal epithelium in the rat Lynn M. C. Pilsworth, B. T. Hinton and B. P. Setchell Department ofPhysiology, A.R.C. Institute ofAnimal Physiology, Babraham, Cambridge CB2 4AT, UK. Summary. Blocking the lumen of a single seminiferous tubule by introducing a plug of non-toxic latex produced a lesion in that tubule, but not in immediately adjacent tubules. The lesion extended for up to 50 mm from the end of the latex. Nearest to the block the tubule was completely aspermatogenic; further along the tubule, the lesion was less severe, involving disorganization and reduction in germ cell numbers, with the cells showing vacuolation, pycnosis and karyolysis. Binucleate and giant cells were common, and cells were often exfoliated into the lumen. The lesion tended to increase in length with longer times after introduction of the plug, but there appeared to be no preferential involvement of the shorter segment of the tubule between the block and the rete. The transition from damaged to healthy tubule was abrupt. Introduction The blood-testis barrier controls the composition of the seminiferous tubule fluid, which is thought to be important for the nurture of germ cells. Its composition probably reflects the conditions within the adluminal compartment of the germinal epithelium in which meiosis is completed (Setchell, 1970, 1978, 1980; Setchell & Waites, 1975). In addition, a possible involvement of fluid in the entrainment of the spermatogenic wave has been suggested (Perey, Clermont & Leblond, 1961) and flow of fluid may be important in the regulation of spermatogenesis.

Under the auspices of the World Association of Veterinary Anatomists (W.A.V.A.), the International Committee on Veterinary Anatomical Nomenclature (I.C.V.A.N.) appointed in Giessen, 1965, a Subcommittee on Histology and Embryology which started a working relation with the Subcommittee on Histology of the former International Anatomical Nomenclature Committee. In Mexico City, 1971, this Subcommittee presented a document entitled Nomina Histologica Veterinaria: A Working Draft as a basis for the continued work of the newly-appointed Subcommittee on Histological Nomenclature. This resulted in the editing of the Nomina Histologica Veterinaria: A Working Draft II (Toulouse, 1974), followed by preparations for publication of a Nomina Histologica Veterinaria.
