spermatogenic cycle
duration of the cycle which separates consecutive cell divisions of spermatogonia (pig is 8 days, sheep 10, cattle 14) to produce spermatocytes.
spermatogenic wave
spermatogenesis occurs in sequential waves along the length of the seminiferous tubules so that spermatozoa are produced in waves; the phenomenon which ensures that spermatozoa are produced continuously, except for seasonal pauses when spermatogenesis is initiated and terminated each year.

This deletion almost always results in spermatogenic failure, so it would be extremely rare for it to be transmitted from father to son without medically assisted reproduction," said Page.
In the seminiferous tubules of sexually mature animals, the spermatogenic cells are not randomly arranged, but organized as a well-defined series of cellular associations or stages.
cfsRNA also has potential as a replacement biomarker of spermatogenic activity and malignant diseases and may thereby overcome the drawbacks and misdiagnoses associated with testicular biopsy.
of Wurzburg, Germany) presents 20 papers detailing select recent advances in mouse spermatogenesis research, which has progressed more rapidly than other investigations into the identification, immunolocalization, and biochemical characterization of proteins expressed in mammalian spermatogenic cells due to the feasibility of producing genetically manipulated animals and the information provided by the mouse genome project.
A certain structural change called adducts can occur in the DNA of spermatogenic cells in response to genotoxins.
Although the evolutionary histories of rats and mice diverged 11 million years ago, the spermatogenic process has changed so little that mice testes can support the germ cells of rats and produce fully normal sperm, says Brinster.
At 180 mg/kg/day (which produces exposure levels 22 times higher than those in humans taking 80 mg/day based on surface area, mg/m2), seminiferous tubule degeneration (necrosis and loss of spermatogenic epithelium) was observed.
At 15 [micro]M/kg, spermatogenic cells next to the basement membrane were pyknotic.
The weight of testes is largely dependent on the mass of differentiated spermatogenic cells, but the reduction of their weights, was consistent with elimination of germ cells [39].
7,8) Coupled with the fact that prior anabolic steroid use is common in young men seeking treatment for symptomatic hypogonadism, (9) the potential for decreased spermatogenic capacity and compromised reproductive function in young, hypogonadal men is possible.
Different spermatogenic cells (spermatogonia, primary spermatocytes, early spermatids, late spermatids and spermatozoa) and Sertoli cells were identified according to their distinct morphological characteristics as described by Leme and Papa (2010) and Santos et al.
In each male, the following testicular lesions were scored: (1) hemocytic infiltration of the gonadal acini and phagocytosis of spermatogenic cells, (2) hemocytic infiltration of interacinal connective tissue, (3) aggregations of hemocytes under the mantle epithelium, and (4) occurrence of brown cells.
