Cryptorchidism in Sheep: A Clinical and Abattoir Survey in the United Kingdom
Sheep Cryptorchid Abattoir Survey
2013/2/19
This paper describes features of a study of different aspects of cryptorchidism in sheep in different parts of England. A total of 83 crytorchid testes (57 unilateral and 13 bilateral) were recognised...
Bilateral Intratesticular Varicocele in a Patient with a History of Bilateral Cryptorchidism
Cryptorchidism Intratesticular varicocele Doppler ultrasound
2009/6/25
Intratesticular varicocele (ITV) is characterized by dilatation of intratesticular veins in and around the mediastinum testis (1-7). Since it is a rare entity, its clinical implications are unknown. I...
Effects of experimental cryptorchidism and subsequent orchidopexy on seminiferous tubule functions in the lamb
experimental cryptorchidism subsequent orchidopexy seminiferous tubule functions lamb
2009/2/23
The reversibility of damage caused by cryptorchidism to the seminiferous tubules of the lamb was investigated at various ages. Lambs were made bilaterally cryptorchid either at birth or at 2 month...
Effect of cryptorchidism and orchidopexy on inhibin secretion by rat Sertoli cells
cryptorchidism orchidopexy inhibin secretion rat Sertoli cells
2009/2/19
The present study explored the effects of experimental bilateral cryptorchidism (of 21-, 28-, and 35-days duration) and orchidopexy (14 and 42 days) in the adult rat on the secretion of inhibin by c...
Effect of cryptorchidism and orchidopexy on inhibin secretion by rat Sertoli cells

2009/2/19
The present study explored the effects of experimental bilateral cryptorchidism (of 21-, 28-, and 35-days duration) and orchidopexy (14 and 42 days) in the adult rat on the secretion of inhibin by c...
Modification of Sertoli Cell Responsiveness to FSH by Cryptorchidism and Hypophysectomy in Immature and Adult Rats
rat cryptorchidy hypophysectomy cAMP Sertoli cell
2009/2/19
Cryptorchid or hypophysectomized rats were used as models to examine the possible relationships between germ cell development and gonadotropins in the agerelated decline in the responsiveness of t...
The Effects of Experimental Cryptorchidism on the Entry of [3H]-Inulin and [3H]-Horseradish Peroxidase into the Lumen of the Rat Seminiferous Tubules
cryptorchidism blood-testis barrier rat testicle seminiferous tubule
2009/2/19
The objective of this research was to determine if experimental cryptorchidism causes significant changes in the rat blood-testis barrier. Micropuncture of the seminiferous tubules of normal, sham...
Experimental cryptorchidism in the adult mouse. III. Qualitative and quantitative electron microscopic morphology of Leydig cells
Experimental cryptorchidism adult mouse Leydig cells
2009/2/7
The morphology of Leydig cells of control and 28-day-old cryptorchid mice was studied by electron microscopy and stereologic techniques. Leydig cell profiles of control mice were larger in section...
Experimental cryptorchidism in the adult mouse：II. A hormonal study
Leydig cells FSH LH testosterone hCG radioimmunoassay
2009/2/6
Serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone levels and secretory capacity of the in vitro stimulated testis were determined in control and bilateral cryptorc...
Experimental cryptorchidism in the adult mouse：I. Qualitative and quantitative light microscopic morphology
Testis Leydig cells stereology hyperplasia,hypotrophy
2009/2/6
Morphologic changes in the testes of adult mice after experimentally induced cryptorchidism were studied by light microscopy and stereology. Increasing duration of cryptorchidism resulted in a gradu...

Male infertility is a common side effect of aggressive cancer chemotherapy. One possible approach to decreasing gonadal injury in this setting is the production of artificial cryptorchidism (elevati...
cAMP response of cultured Sertoli cells from immature and adult hamsters. Effect of hypophysectomy and cryptorchidism
cultured Sertoli cells immature and adult hamsters hypophysectomy cryptorchidism
2009/2/6
The ability of FSH to stimulate cAMP accumulation in Sertoli cells cultured from either hamsters or rats declines with the age of the animal. Hypophysectomy or bilateral cryptorchidism of immature r...
