A large part of germ cells die apoptotically during testicular development in rodents. In the
present study, a wave of germ cell apoptosis was observed between days 10 and 30 of …

Germ cell apoptosis was evaluated in 11 men suffering from nonobstructive azoospermia
and enrolled in a spermatid conception programme. In six of these patients, round …

Spontaneous death of certain classes of germ cells has been shown to be a constant feature
of normal spermatogenesis in a variety of mammalian species, including the human. Recent …

Apoptosis appears to have an essential role in the control of germ cell number in testes.
During spermatogenesis germ cell deletion has been estimated to result in the loss of up to …

The physiological apoptosis that occurs in immature testis appears to be necessary for the
maturation of this tissue. Thus, inhibition of the early apoptotic wave associated with the first …

BACKGROUND: Features of both apoptosis and necrosis have been reported in ejaculated
human spermatozoa. This study examines the relative contribution of these two modes of …

Objective: To determine, using an in situ end-labeling technique, whether the frequency of
apoptosis is increased in testis biopsy specimens that demonstrate abnormal …

In this work we apply the Hoechst 33258 DNA staining, the TUNEL procedure and
conventional electron microscopy to study the ejaculate of fertile and infertile men, in order …

Histological studies by Clermont and his colleagues in the 50s and 60s (1, 2) form a basis of
the current understanding of the dynamics of spermatogenesis and its hormonal control …

Cellular apoptosis appears to be a constant feature in the adult testis and during early
development. This is essential because mammalian spermatogenesis is a complex process …
