failure to respond adequately to standard protocols and to recruit adequate follicles is called ‘poor response’. this results in decreased oocyte production, cycle cancellation and, overall, is associated with a significantly diminished probability of pregnancy. it has been shown that ovarian reserve tests, such as basal fsh, antimullarian hormone (amh), inhibin b, basal estradiol, antral folli...
background: the ability of the ovary to respond to exogenous gonadotrophin stimulation and development of several follicles is essential in assisted reproductive technology. neither age and regularity of menses nor follicular phase fsh and estradiol concentrations are reliable predictors of ovarian response. day 3 serum inhibin-b level, during induction ovulation, has been proposed as a predict...
background: poor ovarian response to controlled ovarian stimulation is one of the most important interest points in assisted reproduction. mild ovarian stimulation seems to be preferable to high dose of fsh regimens in women with a history of poor ovarian response in previous protocol. clomiphene citrate and letrozole alone or in combination with fsh have been used in mild ovarian stimulation p...
as lactating cows in severe negative energy balance have poor reproductive performance, the effect of dietary fat supplementation (fish oil, soybean oil) on pgfm secretion, ovarian function and blood metabolites is investigated. in this experiment, the effects of dietary polyunsaturated fatty acids on plasma metabolites, ovarian function and prostaglandin secretion of 20 primiparous holstein co...
As lactating cows in severe negative energy balance have poor reproductive performance, the effect of dietary fat supplementation (fish oil, soybean oil) on PGFM secretion, ovarian function and blood metabolites is investigated. In this experiment, the effects of dietary polyunsaturated fatty acids on plasma metabolites, ovarian function and prostaglandin secretion of 20 primiparous Holstein co...
background: poor ovarian response phenomenon has been observed in some of the in vitro fertilization-embryo transfer patients. some investigations found that follicle stimulating hormone receptor (fshr) gene plays a role in the process, but no direct evidence shows the correlation between genotypes of fshr and ovarian response. objective: exploring the molecular mechanism behind the mutation of...
Background To compare a flexible, multi-dose GnRH antagonist protocol with a long GnRH .agonist protocol in poor respo MaterialsAndMethods A randomized clinical trial of 70 poor responder patients (35 patients in GnRH antagonist protocol and 35 patients in long GnRH agonist protocol) was performed at Royan Institute, Tehran, Iran. Both groups were given a fixed dose of human menopausal gonadotr...
The Hippo pathway is dysregulated in multiple types of human cancer, including ovarian cancer. Nuclear expression of yes-associated protein 1 (YAP1), a downstream transcription coactivator of the Hippo pathway, has been demonstrated to promote tumorigenesis in ovarian cancer and may serve as a poor prognostic indicator. However, transcriptional coactivator with PDZ binding motif (TAZ), a downst...
background: mellitus diabetes (dm) is the most important metabolic diseases. the incidence of dm is prone to increase. vasculopathy, retinopathy, central and peripheral neuropathy are the most important reported side effects of dm. cognitive dysfunction following dm reported in both sexes. hippocampus is a major part of brain involving in cognitive function, its cells are able to neurogenesis, ...
