In many organisms, programmed cell death of germ cells is required for normal
development. This often occurs through highly conserved events including the transfer of …

Apoptosis is an important cellular process by which superfluous or unwanted cells are
deleted from an organism during tissue remodeling and differentiation. Recent studies have …

The prostate gland in adult male rats is highly dependent on androgenic steroids. Castration
initiates the regression of this tissue through a process involving the loss of the vast majority …

Germ cell degeneration is common in mammalian testes during the developmental as well
as the adult period. To investigate the extent and mechanisms of male germ cell death …

Testicular germ cell tumours are hypersentive to chemotherapy and cell lines derived from
these tumours are chemosensitive in vitro. We have previously shown that these cell lines …

Spermatogenesis is a highly synchronized process in which FSH and testosterone are
considered the major regulators. Nevertheless, the mechanism by which these hormones …

BACKGROUND: The aim of the present study was to define the effect of apoptosis on sperm
quality and function. METHODS: The apoptotic features in sperm were assessed in 60 …

The mammalian seminiferous epithelium consists of a highly complex yet well-organized
cell population, with germ cells in mitosis and meiosis and postmeiotic cells undergoing …

Cytoplasmic caudal tags of maturing spermatids condense and are detached from the
spermatidal cells just before the spermatids are released as spermatozoa. The detached …

The major objectives of the present study were to document the temporal and stage-specific
acceleration of germ cell apoptosis in adult rats after selective suppression of pituitary …
