Cystic spermatogenesis in three species of the prolixus complex (Hemiptera: Triatominae)
(Taylor &francis Ltd, 2015-04-03)
The reproductive biology of triatomines and, more specifically, the general aspects of spermatogenesis and spermiogenesis are well known. However, reported structural analyses of the testicles are restricted to the genus ...
Observations on the Spermatogenesis of Some Scarabaeoid BeetlesObservations on the Spermatogenesis of Some Scarabaeoid Beetles
(University of Puerto Rico Mayagüez Campus Agricultural Experiment Station, 1966)
Spermatogenesis and karyotypes of three species of water striders (Gerridae, Heteroptera).
(2010-10-27)
Although they are of economic importance, there have been few cytogenetic studies of the Gerridae (Heteroptera) in Brazil. We examined spermatogenesis (meiosis and spermiogenesis) and nucleolar behavior in three species ...
Estrogen-induced inhibition of spermatogenesis in zebrafish is largely reversed by androgen
(Bioscientifica Ltd, 2018-05-01)
The hormonal regulation of spermatogenesis involves both gonadotropins and steroid hormones. Long-term in vivo exposure of adult zebrafish to estrogen impaired spermatogenesis associated with an androgen insufficiency, ...
An overview of functional and stereological evaluation of spermatogenesis and germ cell transplantation in fish
(2009-01-01)
Although there are almost thirty-thousand species of fish living in a great variety of habitats and utilizing vast reproductive strategies, our knowledge of morphofunctional and quantitative aspects of testis structure and ...

Ultrastructural Study of Spermatogenesis in Eisenia foetida (Annelida, Oligochaeta)
(Sociedad Chilena de Anatomía, 2007)
Morphological study of the spermatogenesis in the teleost Piaractus mesopotamicus
(Inst Histol Embriol-conicet, 2003-12-01)
The spermatogenesis of Piaractus mesopotamicus was investigated under light and transmission electron microscopy. The specimens were captured from their natural environment (Rio Miranda and Rio Aquidauana, Pantanal ...
