Maternal supplementation with corn oil associated or not with di-n-butyl phthalate increases circulating estradiol levels of gerbil offspring and impairs sperm reserve
(2018-10-01)
This study evaluated the consequences of gestational exposure to di-n-butyl phthalate (DBP) for testicular steroidogenesis and sperm parameters of the adult gerbil and the interference of corn oil (co), a vehicle widely ...
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 ...
Tritrichomonas fetus extracellular products decrease progressive motility of bull sperm
(Elsevier B.V., 2010-01-01)
Tritrichomonas fetus causes infertility and abortion in cattle; however, there is scarce information regarding the susceptibility of bovine sperm to this parasite. The objective of this study was to analyze in vitro the ...
Relationship between DNA damage and sperm head birefringence
(Elsevier B.V., 2011-06-01)
Birefringence or double refraction is the decomposition of a ray of light into two rays when it passes through an anisotropic material such as quartz. Sperm cells have been demonstrated to be optically anisotropic. The ...
Blood and seminal plasma concentrations of selenium, zinc and testosterone and their relationship to sperm quality and testicular biometry in domestic cats
(Elsevier B.V., 2014-11-10)
The aim of this study was to assess seminal plasma (SP) and serum concentrations of zinc (Zn), selenium (Se) and testosterone (T) in domestic cats and determine whether these are related to sperm quality and testicular ...
Glutamate-induced obesity leads to decreased sperm reserves and acceleration of transit time in the epididymis of adult male rats
(Biomed Central Ltd., 2012-12-05)
Background: Given the established fact that obesity interferes with male reproductive functions, the present study aimed to evaluate sperm production in the testis and storage in the epididymis in a glutamate-induced model ...
Acceleration of Sperm Transit Time and Reduction of Sperm Reserves in the Epididymis of Rats Exposed to Sibutramine
(Amer Soc Andrology, Inc, 2011-11-01)
Sibutramine is a drug globally used for the treatment of obesity. The aim of this study was to investigate male reproductive disorders caused by sibutramine in adult rats. Wistar rats were treated for 28 consecutive days ...
Sexual maturation of the Mongolian gerbil (Meriones unguiculatus): a histological, hormonal and spermatic evaluation
(2014)
This study determined the phases of sexual development of the male Mongolian gerbil (Meriones unguiculatus) based on an integrative analysis of testicular morphology, hormonal data and sperm parameters. Male gerbils were ...
Gonadic Sperm Reserve in Buffaloes Created under Tropical Conditions
(Pagepress Publ, 2007-01-01)
The objective of the present study was quantifying the spermatic production per gram and daily rate of the testicular parenchyma. Testis of 12 crossbred Murrah buffaloes aged 24 to 48 months created under extensive conditions ...
