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...

This study was undertaken to determine the effects of various durations of testicular torsion in prepubertal rats on their subsequent fertility, and to determine whether these effects could be alter...
The effect of exogenous follicle stimulating hormone treatment on anterior pituitary and testicular function in the prepubertal bull
follicle stimulating hormone luteinizing hormone testosterone prepubertal bull
2009/2/20
The effect of exogenous follicle stimulating hormone (FSH) on testicular function was studied in twenty 4-month-old Holstein bulls during two seasons (ten in late winter and ten in summer). Five mg ...
Round spermatids from prepubertal mouse testis can develop into normal offspring
ICSI genomic imprinting centriole

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
2009/2/17
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/...
Testosterone regulation of proto-oncogene c-myc expression in primary Sertoli cell cultures from prepubertal rats
Cyclohexlmlde testis actinomycin-D
