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 …

Seminiferous tubule differentiation was related to the occurrence of germ cell neoplasia in
38 men, aged 17-47, treated surgically in childhood for cryptorchidism. Tissues from 46 …

Seventy‐three testicular biopsies from 54 children (aged 2 months‐14 years) with
undescended testes were examined by light and electron microscopy. The biopsies …

The observation of different types of seminiferous tubules (from tubules with normal
spermatogenesis to sclerosed tubules) in aging human testes points to the progressive …

Testicular biopsy specimens from adult patients affected with cryptorchidism, Klinefelter's
syndrome, and Del Castillo's syndrome were examined by light and electron microscopy …

A hormonal and quantitative light microscopy study of one man with macro-orchidism
associated with mental retardation and fragile X chromosome (case no. 1) and three men …

A quantitative and ultrastructural study was performed on biopsies of human cryptorchid
testes to investigate lesions in the lamina propria and Sertoli cells. Prepubertal cryptorchid …

Ultractructural study of seminiferous tubules in ageing men revealed a varying degree of
spermatogenetic arrest associated with changes in the Sertoli cells. Approximately half of …

The histological pattern, volumetric fractions (VF) of tubular and interstitial tissue and the
germinal cells, and the mean tubular diameter (MTD) were studied in 175 biopsies from 134 …

A spermatocele refers to the cystic accumulation of semen in the male reproductive tract.
Although it is thought to be caused by narrowing of the lumen of the excurrent duct with …
