Protection from procarbazine-induced testicular damage by hormonal pretreatment does not involve arrest of spermatogonial proliferation
-
of special interest. Hormone treatments that suppress sperm production enhance the recovery of spermatogenesis after gonadal exposure to various cytotoxic agents. While it was generally assumed that the mechanism of protection involved an arrest of spermatogonial kinetics, no decrease or inhibition in spermatogonial cell numbers and bromodeoxyuridine incorporation were observed. Thus, changes in spermatogonial numbers or suppression of their proliferation cannot account for protection of spermatogenesis from exposure to cytotoxic agents.

Hormone treatment after irradiation stimulates recovery of rat spermatogenesis from surviving spermatogonia
-
of outstanding interest. In LBNF rats, after irradiation there is a depletion of the seminiferous epithelium followed by recovery from surviving spermatogonial stem cells. Thereafter, surprisingly, spermatogenesis deteriorates and ultimately actively dividing A spermatogonia remain unable to produce more differentiated cells. Suppression of gonadotropin and testosterone levels through GnRH agonist (GnRH-Ag) treatment or continuous treatment with testosterone markedly stimulates the recovery of spermatogenesis. Sperm counts in GnRH-treated rats were 100-fold higher than in untreated rats. Since all of the hormone treatments suppress intratesticular testosterone, it is suggested that high levels of testosterone inhibit differentiation and their suppression may stimulate recovery.

Leuprolide, a gonadotropin-releasing hormone agonist, reestablishes spermatogenesis after 2,5-hexanedione-induced irreversible testicular injury in the rat, resulting in normalized stem cell factor expression
-
of outstanding interest Shows that at the start of spermatogenesis Sertoli cells shift the production of stem cell factor (SCF) from the soluble form to the membrane-bound form. In 2,5-hexanedione-treated rats with deteriorated spermatogenesis the Sertoli cells predominantly produce soluble SCF. Suppression of gonadotropic hormones in these rats causes a recovery of spermatogenesis and in the Sertoli cells an increased production of membrane-bound SCF takes place. Hence, the quality of the spermatogenic process correlates with the production of membrane bound SCF.

Testicular degeneration in Bclw-deficient mice
-
of special interest. Mice deficient for the apoptosis-promoting protein Bclw exhibit sterility associated with progressive testicular degeneration. Germ-cell defects are first observed at 19 days after birth and spermatogenesis is blocked during late spermiogenesis in young adults. Gradual depletion of all stages of germ cells results in a Sertoli-cell-only phenotype by approximately six months of age. Subsequently, almost all Sertoli cells are lost from the seminiferous tubules and in the interstitial tissue, in between the seminiferous tubules, the numbers of testosterone producing Leydig cells is reduced. Expression of the Bclw protein in the testis appears to be restricted to elongating spermatids and Sertoli cells.

The meiotic checkpoint monitoring synapsis eliminates spermatocytes via p53-independent apoptosis
-
of special interest. Double strand breaks in the DNA, induced by irradiation, are known to trigger apoptosis in a number of cell types via a p53-dependent pathway. It is shown that irradiation-induced spermatogonial apoptosis is also p53-dependent. In contrast, the apoptotic elimination of spermatocytes with synaptic errors proved to be p53-independent.

of special interest. It is shown that, at three weeks of age, in mice homozygous for the jsd (juvenile spermatogonial depletion) allele, most seminiferous tubular cross-sections show spermatocytes but fewer cross-sections show spermatids than in wild-type mice. At six weeks of age in jsd/jsd mouse testes, fewer B spermatogonia are formed than in wild-type mice. Already at three weeks of age in jsd/jsd mice tubular cross-sections showing only A spermatogonia are present.
