Androgen deprivation from pre-puberty to peripuberty interferes in proteins expression in pubertal and adult rat epididymis
(2013-07-01)
Few studies have focused on experimental testosterone deprivation in immature animals. Therefore, this study used sexually immature rats aiming to evaluate the testes and epididymis histology and proteins expression in ...
Morphological features of the epididymal epithelium of gerbil, Meriones unguiculatus
(Churchill Livingstone, 2007-02-01)
Principal cells of the ducts epididymis of the Mongolian gerbil showed ultrastructural characteristics of lining epithelium cells close related to processes of protein secretion, and transcytosis occurring between adjacent ...
Sexual behaviour, sperm quantity and quality after short-term streptozotocin-induced hyperglycaemia in rats
(Blackwell Publishing, 2006-08-01)
Studies of diabetes mellitus in the streptozotocin rat model suggest that sexual dysfunctions may result from diabetes-induced alterations of the neuroendocrine-reproductive tract axis. Our investigation was performed to ...
Effects of altered epididymal sperm transit time on sperm quality
(Wiley-Blackwell, 2008-08-01)
The epididymal sperm transit time seems to have an important role in the process of sperm maturation, and it seems that alterations to the transit can harm the process. The aim of the present work was to evaluate the ...
Impairment on sperm quality and fertility of adult rats after antiandrogen exposure during prepuberty
(Pergamon-Elsevier B.V. Ltd, 2012-06-01)
This study evaluated the effects of antiandrogen exposure during the prepubertal period on reproductive development and reproductive competence in adults. Male rats were divided into two groups: flutamide, receiving 25 ...
Sperm motility in ocellate river stingrays: evidence for post-testicular sperm maturation and capacitation in Chondrichthyes
(Wiley-Blackwell, 2019-01-01)
Sperm maturation, as a process through which spermatozoa acquire the ability for motility activation and fertilization, is well-known for many groups of animals. This process takes place in a taxon-specific manner in ...
Can maternal exposure to tamoxifen compromise sperm and behavioural parameters of male rat offspring?
(2022-03-01)
Tamoxifen, a selective non-steroidal estrogen receptor modulator, is the standard adjuvant endocrine treatment for breast cancer. Since information on the risk of using tamoxifen during pregnancy is still scarce, this study ...
Morphology and immunolocalization of aquaporins 1 and 9 in the agouti (Dasyprocta azarae) testis excurrent ducts
(2021-01-01)
This study investigated the morphology and immunoexpression of aquaporins (AQPs) 1 and 9 in the rete testis, efferent ducts, epididymis, and vas deferens in the Azara's agouti (Dasyprocta azarae). For this purpose, ten ...
Some aspects of stallion epididymal sperm maturation
(1997)
It is clear at present that important maturation changes take place in spermatozoa in the epididymis, and that these changes confer on the sperm the ability to fertilize eggs. This process has been scarcely analyzed in the ...
Decrease in sperm number after treatment of rats with Austroplenckia populnea
(Elsevier B.V., 2000-07-01)
The purpose of this study was to evaluate the effects of a hexanic extract (HE) made from leaves of A. populnea collected in Botucatu, State of São Paulo, and Nova Lima, State of Minas Gerais, Brazil, at a range of doses ...
