Recombinant versus urinary gonadotrophins for triggering ovulation in assisted conception.
BACKGROUND The objective of this systematic review was to assess the safety and efficacy of subcutaneous recombinant (r) HCG and high-dose rLH compared with intramuscular urinary (u) uHCG for inducing final oocyte maturation and triggering ovulation. METHODS We searched the Cochrane Menstrual Disorders and Subfertility Group trials register (August 27, 2003), the Cochrane Central Register of ...
متن کاملTransgenic animals and gonadotrophins.
A variety of transgenic animal models has been developed to elucidate in vivo the functions of gonadotrophin genes. Some of these have focused on regulatory aspects through expression of gonadotrophin subunit promoter-driven reporter genes. Others have been carried out by overexpression or targeted disruption of specific gonadotrophin subunit genes, or by eliminating pituitary gonadotroph cells...
متن کاملBye-bye urinary gonadotrophins? Recombinant FSH: a real progress in ovulation induction and IVF?
Whether recombinant gonadotrophin products do, indeed, represent progress for routine ovulation induction and IVF cycles, in comparison with urinary products, has remained controversial. Here we review published data with regard to respective risks, outcomes and cost for both medication options. Safety considerations favour recombinant products, while overall outcome and cost considerations fav...

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...
