Background One of the common gonadotropin hormones used for infertility treatment is recombinant Follicle stimulating hormone (rFSH). pH is an environmental factor that can affect production of recombinant proteins with no imposing cost. Culture pH is known as a parameter that significantly affects cell growth and protein production. In this study, tried to investigate the effect of different p...
STUDY QUESTION Does the sperm DNA fragmentation index (DFI) improve depending on the FSH receptor (FSHR) genotype as assessed by the nonsynonymous polymorphisms rs6166 (p.N680S) after 3 months of recombinant FSH treatment in men with idiopathic infertility? SUMMARY ANSWER FSH treatment significantly improves sperm DFI only in idiopathic infertile men with the p.N680S homozygous N FSHR. WHAT...
Background Poor and fragmentary data was available regarding the effects of recombinant-LH (r-LH) in in-vitro granulosa and theca cells of human origin. No data was available from in vivo studies regarding the effects of r-LH supplementation on SCF,EGF,ERK-1/2 and AKT-1 pathways in the follicular fluid of older-poor-responder women undergoing IVF cycle. Evidence from in-vitro and animal studies...
Background: Infertility is defined as failure to achieve pregnancy after one year of unprotected sexual intercourse. Infertility can be related to male or female factors. Varicocele is the most common cause of infertility in men that is correctable with surgery. The purpose of this study was to determine the effects of recombinant follicle-stimulating hormone (rFSH) on semen parameters in infer...
Abstract Study question Is the cost per oocyte lower in antagonist ovarian stimulation protocol vs progestin primed donation program? Summary answer The is program What known already 1. use of progesterone during effective blocking LH surge, and it does not affect number oocytes collected or quality embryos obtained. Progestins can be used orally are less expensive than GnRH analogues. These ne...
Previous studies from our laboratory, demonstrating that suppression of serum FSH by RU486 requires a high estrogen (E) background, suggested that E-inducible progesterone receptors play a role in the regulation of FSH secretion. We demonstrated further that the type II antiprogestin RU486 and the type I antiprogestin ZK98299 both suppressed the elevated serum FSH and FSHbeta messenger RNA leve...
