Pituitary gonadotrophins of the progeny of x-irradiated female mice with altered phenotypic characters.

Effect of vitamin E on preovulatory stage irradiated female mouse expressed as chromosomal abnormalities in generated embryos

Background: The present study has been carried out to investigate the effects of preovulatory stage gamma-irradiation of female mice in the absence or presence of vitamin E on numerical chromosome abnormalities in 8-cell embryos after mating with non-irradiated males. Materials and Methods: The 8-11 weeks adult female NMRI mice were whole body irradiated at preovulatory stage (post PMSG inject...

The Impact of Pituitary Blockage with GnRH Antagonist and Gonadotrophin Stimulation Length on The Outcome of ICSI Cycles in Women Older than 36 Years

Sperm DNA damage in mice irradiated with various doses of X-rays alone or in combination with actinomycin D or bleomycin sulfate: an in vivo study

Background: DNA damage in male germ cells due to exposure to environmental and manmade physico-chemical genotoxic agents is considered as the main cause of male infertility. The aim of this study was to evaluate the effects of combined modalities (radiotherapy and chemotherapy) routinely used for cancer treatment on mouse sperm chromatin in vivo. Materials and Methods: Forty-eight mice were div...

Effects of Cypermethrin on Sexual Behaviour and Plasma Concentrations of Pituitary-Gonadal Hormones

Background Pyrethroids are commonly used as insecticides for both household and agricultural applications, and have recently been linked to endocrine disruption. Cypermethrin is a type П pyrethroid which is used widely throughout the world. The present study was aimed to investigate the effects of cypermethrin on the sexual behaviour and plasma level of pituitary-gonadal hormones of adult male ...

Role of low level laser in ameliorating the damaging effects of gamma irradiation on mice liver

Background: Exposure to ionizing radiation is inevitable. Using of low-level laser therapy (LLLT) stimulates tissue repair and reduces inflammation. The objective of the present study aimed at evaluating the therapeutic efficacy of Helium-Neon (He-Ne) laser in stimulating the reparative processes in the liver of mice after whole body gamma-irradiation (WBγ-I). Materials and Methods: Two hundred...
