Superovulation of immature hypothyroid rdw rats by thyroxine therapy and the development of eggs after in vitro fertilization.
The aim of this study was to examine the effect of thyroxine on ovulation in immature rdw rats and the fertilization and development of the eggs. Serum thyroxine concentrations at 30 days of age were significantly lower in rdw rats than in normal rats (P < 0.001), and greatly increased after thyroxine replacement therapy (P < 0.001). Although few eggs (1-5 +/- 1-2) were obtained from immature r...
متن کاملAn immunological cross reaction between monkey gonadotrophin preparations and antisera to human gonadotrophins.
There is still some confusion about the ability of monkey and human gonadotrophins to cross react in immunological systems. McGarry & Beck (1963), using a haemagglutination inhibition technique, found a cross reaction between antisera to human fsh and monkey fsh. They also found a similar cross reaction with lh. Neill, Peckham & Knobil (1967), Bagshawe, Orr & Godden (1968) and Faiman, Ryan, Gre...
متن کاملUrinary gonadotrophins but not recombinant gonadotrophins reduce expression of VEGF120 and its receptors flt-1 and flk-1 in the mouse uterus during the peri-implantation period.
BACKGROUND Ovarian stimulation in humans might affect the perinatal outcome and be considered as a stress factor in the implantation process. In this study we compared the effects of recombinant and urinary gonadotrophins during the mouse peri-implantation period. METHODS Adult female CD1 mice were treated as follows (a) urinary hFSH and urinary hCG, (b) recombinant hFSH and recombinant hLH a...

متن کاملEffect of Metronidazole on Spermatogenesis, Plasma Gonadotrophins and Testosterone in Male Rats
Metronidazole and it’s derivatives are drugs that have both antiprotozoal and anti bacterial effect.The reproductive toxicity of metronidazole has been shown in some studies. To investigate the effect of metronidazole on spermatogenesis in adult male rats, this study was designed. Eighteen wistar male rats (70-90days old) were randomly divided into three groups. Animals in group I (Control grou...
