Age-related changes in the concentration of cytosolic androgen receptors in the epididymis, vas deferens and seminal vesicle of maturing male mice
Age-related changes cytosolic androgen receptors epididymis
2009/2/23
In this study, changes in the number of androgen binding sites that occur in cytosols of epididymis, vas deferens and seminal vesicle of mice from 10 to 90 days of age are described. Specific satura...
Influence of photoperiod, ambient temperature and melatonin on testosterone synthesis and release during reproductive maturation in male deer mice
photoperiod ambient temperature melatonin testosterone synthesis reproductive maturation male deer mice
2009/2/23
Four experiments were designed to investigate the influence of photoperiod and other environmental factors on androgen production and reproductive maturation in deer mice. Male prairie deer mice (Pe...
Further characterization of a secreted epididymal glycoprotein in mice that binds to sperm tails
Further characterization secreted epididymal glycoprotein mice sperm tails
2009/2/23
Sperm maturation antigen 4 (SMA-4) is a surface component of the mouse sperm tail. Previously, immunofluorescence studies indicated that SMA-4 may be secreted by principal cells of the distal caput ...
The nonprogressive motility of sperm populations from mice with a tw32 haplotype
nonprogressive motility sperm populations mice tw32 haplotype
2009/2/19
We have previously reported that epididymal spermatozoa from mice carrying a tw32 haplotype have a lower net velocity than do spermatozoa from congenic +/+ males. Using a test for nonprogressive mot...
Effects of Photoperiod and Subcutaneous Melatonin Implants on the Reproductive Status of Adult White-footed Mice（Peromyscus leucopus）
implant melatonin photoperiod white-footed mouse Peromyscus leucopus testosterone
2009/2/19
The reproductive consequences of photoperiod and melatonin administration were compared in adult white-footed mice (Peromyscus leucopus). Animals were exposed either to a long photoperiod (16 hours ...
Interactive Effects of Ethanol and 9-Tetrahydrocannabinol on Endocrine Functions in Male Mice
ethanol 9-tetrahydrocannabinol testes in vitro testosterone production plasma testosterone
2009/2/19
Exposure during sexual maturation to alcohol (ETOH) plus 9-tetrahydrocannabinol (THC) significantly decreased the weights of adrenals, kidneys, testes, and emptied seminal vesicles ten days after ce...
II. Characterization and development of the regional- and cellular-specific abnormalities in the epididymis of mice with beta-hexosaminidase A deficiency
II. Characterization regional- and cellular-specific abnormalities epididymis mice with beta-hexosaminidase A deficiency
2009/2/18
Beta-hexosaminidase (Hex) is a lysosomal enzyme that exists as two isoenzymes: Hex A (subunit structure alphabeta) and Hex B (betabeta). Its presence in the testis and epididymis suggests importan...
I. Abnormalities in cells of the testis, efferent ducts, and epididymis in juvenile and adult mice with beta-hexosaminidase A and B deficiency
cells testis efferent ducts epididymis adult mice beta-hexosaminidase A and B deficiency
2009/2/18
Beta-hexosaminidase (Hex) is a lysosomal enzyme that exists as two major isoenzymes: Hex A (subunit structure, alphabeta) and Hex B (betabeta). The presence of Hex in the testis and epididymis sug...
Spermatic granulomata are experimentally induced in epididymides of mice receiving high-dose testosterone implants. I. A light-microscopical study
Spermatic granulomata high-dose testosterone
2009/2/18
It is known that a spermatic granuloma is induced by the inflammatory reaction following leakage of spermatozoa outside the germ cell ducts and is the main clinical complication of vasectomy. In t...
Quantification of apoptotic testicular germ cells in normal and methoxyacetic acid-treated mice as determined by flow cytometry
Spermatogenesis TUNEL
2009/2/18
Several studies have reported the occurrence and significance of programmed cell death (apoptosis) of testicular germ cells in mammals. In those studies, apoptotic germ cells were identified by mo...
Androgen regulation of the Pem homeodomain gene in mice and rat Sertoli and epididymal cells
Homeobox testosterone promoter testis
2009/2/17
Although the role of homeodomain transcription factors during embryogenesis is well known, their developmental function in postnatal animals is only beginning to be understood. We examined the regul...
Spontaneous degeneration of testicular germ cells in congenitally athymic nude mice of four strains：a light microscopical observation
Spontaneous degeneration testicular germ cells
2009/2/17
Many hormonal studies have demonstrated that the presence of thymic factors affects testicular function. However, morphological studies on the testis in the absence of thymic factors are very limite...
