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 pr...

Background Our objective was to evaluate the effectiveness of clomiphene citrate (CC) vs. letrozole (L) plus human menopausal gonadotropin (hMG) in gonadotropin releasing hormone (GnRH) antagonist protocol in poor prognosis women with previous failed ovarian stimulation undergoing intracytoplasmic sperm injection (ICSI). MaterialsAndMethods This retrospective cohort study included cycles with C...

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: evaluation of anti-mullerian hormone (amh) cut-off levels in assisted reproductive technology (art) as predictive factor for individualization of stimulation protocols and to avoid ovarian hyperstimulation syndrome (ohss). materials and methods: in a retrospective study, 177 infertile patients were assessed for amh in serum and follicular fluid (ff) on the day of follicular puncture...

BACKGROUND The identification of polymorphisms associated with a disease can help to elucidate its pathogenesis, and this knowledge can be used to improve prognosis for women with a particular disorder, such as polycystic ovary syndrome (PCOS). Since an altered response to ovarian stimulation is also a characteristic of the disease, further knowledge about its aetiology could help in defining t...

the objective of this study was to examine the correlation between both midfollicular fsh/lh ratio and number(s) of follicles with ovarian hyperstimulation syndrome (ohss) in patients with polycystic ovarian syndrome (pcos). this was carried out in ivf unit at mirza kouchak khan hospital. to induce ovulation, pcos patients were stimulated with gonadotropines. fifty four pcos patients with norma...

Multiple pregnancies and ovarian hyper stimulation syndrome (OHSS) are the most serious complications of ovarian stimulation and IVF. Indeed, they are more or less the only ones. OHSS can effectively be prevented in three stages: Before stimulation, during stimulation and at ET. Before stimulation patients should be assessed as to age, the ovarian follicular count and/or anti mullerian hormone ...

background: polycystic ovary syndrome (pcos) is associated with approximately 75% of women who suffer from infertility due to anovulation. additionally, around 20– 25% of anovulatory women with pcos do not respond at all to clomiphene citrate and are considered to be “clomiphene– resistant”. aromatase inhibitors have been suggested as an alternative treatment to clomiphene as the discrepancy be...

objective(s) sildenafil citrate is a new drug and has special properties that bring about nitric oxide effects on vascular smooth muscle. the aim of this study was to assess the effects of ovarian stimulation and sildenafil citrate injection on pinopode expression in mice. materials and methods thirty adult female mice were randomly divided into three groups: control, hyperstimulated and hypers...

background: release of vascular endothelial growth factor (vegf) by ovaries in response to hcg administration is one of the main mechanisms of ovarian hyper stimulation syndrome. since dopamine/dopamine receptor2 (dp-r2) pathway activity -mediated by vegf/ vascular endothelial growth factor receptor 2 (vegfr-2) signaling-, is associated with angiogenic events, dopamine agonists were used for th...
