Fetal irradiation increases androgen production by dispersed leydig cells of the rat
seminiferous tubule damage fetal irradiation
2009/2/20
Damage to the seminiferous epithelium of the rat has been shown to decrease the concentration of serum testosterone. In these animals, compared to controls, the structure of the Leydig cells sugge...
The effect of testicular x-irradiation on spermatogenesis in man. A comparison with the mouse
irradiation spermatogenesis testicular
2009/2/20
Existing data concerning the effects of x-irradiation on spermatogenesis in man were analyzed and the results were compared to published data on the mouse. Testicular x-irradiation produced a transi...
Hormone treatment after irradiation stimulates recovery of rat spermatogenesis from surviving spermatogonia
Testis stem cells GnRH-agonist LHRH testosteron
2009/2/17
The possibility of stimulating the recovery of spermatogenesis after irradiation using hormone treatment was tested in LBNF, rats. At 10 weeks after irradiation with 3.5 Gy, the percentage of tubu...
Stage-specific apoptosis in the rat seminiferous epithelium：quantification of irradiation effects
Testis rat apoptosis meiosis irradiation
2009/2/16
The effects of 3 Gy local X-irradiation on the adult rat testis were studied together with exact determination of the radiation dose distribution in the testis. Seminiferous tubule segments were i...

The treatment of seminoma with radiation therapy risks transient infertility. We have prospectively followed eight patients with stage I seminoma of the testicle. All patients underwent radical or...
Comparison of effects of 0.5 and 3.0 Gy X-irradiation on lipid peroxidation and antioxidant enzyme function in rat testis and liver
0.5 and 3.0 Gy X-irradiation lipid peroxidation antioxidant enzyme function rat testis
2009/2/12
The prooxidant effect of X-irradiation on rat testis and liver tissue was studied with doses of 0.5 and 3.0 Gy; the latter dose kills the proliferating spermatogonia and causes a maturation-depletio...
DNA-flow cytometry of defined stages of rat seminiferous epithelium: effects of 3 Gy of high-energy X-irradiation
testis Sertoli germ cell
2009/2/6
Testes of adult Sprague-Dawley rats were irradiated locally by 3 Gy of 4 MeV X-rays produced by a linear accelerator. This type and dose of radiation gives an even distribution through the testis an...
