HCG treatment increases intratesticular pressure in the abdominal testis of unilaterally cryptorchid rats
testis cryptorchidism hCG vascular permeability
2009/2/23
Adult, unilaterally cryptorchid rats were given a single subcutaneous injection of hCG. HCG treatment of 100 I.U. (but not 10 I.U.) resulted in a marked increase in intratesticular pressure (approxi...
Impaired estrogen production by Leydig cells of the naturally retained testis in unilaterally cryptorchid boars and stallions
testis cryptorchid boar stallion estrogens
2009/2/23
Estrogen production in vitro was compared for Leydig cells from cryptorchid and scrotal testes in boars and stallions. Animals with natural and experimental cryptorchidism were used. Purified Leydig...

Seminiferous tubule degeneration human cryptorchid testes
2009/2/20
Two types of degenerating seminiferous tubules were found in cryptorchid testes with Sertoli cell hyperplasia of children and adults: 1) tubules with central degeneration, and 2) tubules with total ...
Spermatids from mice after cryptorchid and reversal operations can initiate normal embryo development
Fertility ICSI cryptorchidism

We investigated fertilization and embryo development following intracytoplasmic injection of round spermatids collected from mice after cryptorchid and reversal operations. The rates of oocyte ac...
Prevention of seminiferous tubular atrophy in a naturally cryptorchid rat model by early surgical intervention
Cryptorchidism orchiopexy testis descent
2009/2/17
In an attempt to determine whether the seminiferous tubular atrophy of the cryptorchid testis is preventable by early surgical correction of the cryptorchid state, aberrantly developed gubernacula d...
Heterogeneity of gonadotropins and levels of uncombined luteinizing hormone subunits in pituitaries of cryptorchid rams
uncombined luteinizing hormone subunits pituitaries cryptorchid rams
2009/2/12
Pituitaries were collected from intact rams and rams that had been rendered bilaterally cryptorchid by surgery to examine the effects of cryptorchidism on gonadotropin heterogeneity, levels of uncom...
