Normal gonadal functions fertility prepubertal male female dogs
2009/2/23
The GnRH agonist [D-Trp6, des-Gly-NH2(10)]GnRH ethylamide was administered to prepubertal male and female dogs daily for 23 months by subcutaneous injection. During GnRH agonist treatment, plasma ster...
Histopathology of prepubertal rat testes subjected to various durations of spermatic cord torsion
spermatic cord torsion rat
2009/2/23
Sixty prepubertal rats were subjected to unilateral spermatic cord torsion for a duration of 0, 1, 3, 5, 9 or 12 hours. At the end of this period, the ipsilateral testes either were removed for imme...

Sertoli cells in the seminiferous epithelium provide both structural and nutritional support to germ cells during spermatogenesis. Primary Sertoli cells in culture are an effective tool for the in v...
Isolation of highly purified type A spermatogonia from prepubertal rat testis
Type A spermatogonia cell separation c-kit cell culture

We have developed a new method that allows isolation of highly purified type A spermatogonia from prepubertal rats. The procedure is based on the maximal release of spermatogonia from the seminifero...
Sperm autoantigens recognized by autoantibodies in developing rats following prepubertal obstruction of the vas deferens
Spermatozoa autoantigens development puberty
2009/2/16
Sperm protein autoantigens recognized by serum antisperm autoantibodies during development following vas deferens obstruction were studied using western blot analysis. At age 10 days, rats in an obs...
Endocrine and exocrine effects of testicular torsion in the prepubertal and adult rat
testicular torsion prepubertal adult rat
2009/2/13
Previous studies of experimental torsion have suggested that there may be important differences between the adult testis and the prepubertal testis in their responses to torsion, especially with reg...
Effects of two non-steroidal antiandrogens on testicular function in prepubertal rats
Testis steroidogenesis flutamide casodex
2009/2/13
The effects of two non-steroidal antiandrogens, flutamide and casodex, were evaluated in prepubertal male rats. Animals (23 days old) were subcutaneously administered vehicle or 1, 2, 5, or 10 mg/...
