BACKGROUND Poor response to ovarian stimulation with exogenous gonadotrophins occurs in 9-24% of women undergoing in vitro fertilisation (IVF) treatment, which represents an estimated 4000-10,000 women per year in the UK. Poor responders often have their treatment cycle cancelled because of expected poor outcome.One treatment strategy that may influence outcome is the choice of pituitary suppre...

OBJECTIVE This study evaluated the use of Corifollitropin alfa in patients with previous poor response to recombinant follicle stimulating hormone in long-term protocols using gonadotropin-releasing hormone. METHODS Twenty-seven poor responders to previous treatment with the long term protocol using the recombinant follicle stimulating hormone (Group 1) were selected and then submitted to a s...

This prospective study examines the benefits of using natural cycles instead of stimulated cycles in poor responders to in-vitro fertilization (IVF) treatment. Eleven patients in whom puncture was cancelled or who failed to conceive because of a poor response were included in the analysis. The data for natural cycles (n = 16) were compared with data obtained during previous stimulated cycles (n...

Long protocol of Gonadotropin-Releasing Hormone-analougue (GnRH-a) can result in the formation of ovarian cyst by the transient initial stimulatory effect which increases the levels of both follicle-stimulating hormone (FSH) and luteinizing hormone (LH). These cysts require surgical drainage or result in poor ovarian response. Ovarian cyst formation can be prevented by taking oral contraceptive...

The objective of the present study was prospectively and randomly to evaluate the role of L-arginine in improving uterine and follicular Doppler flow and in improving ovarian response to gonadotrophin in poor responder women. A total of 34 patients undergoing assisted reproduction was divided in two groups according to different ovarian stimulation protocols: (i) flare-up gonadotrophin-releasin...

BACKGROUND In women, anti-Müllerian hormone (AMH) levels may represent the ovarian follicular pool and could be a useful marker of ovarian reserve. The clinical application of AMH measurement has been proposed in the prediction of quantitative and qualitative aspects in assisted reproductive technologies (ART). In men AMH is secreted in both the serum and seminal fluid. Its measurement may be u...

BACKGROUND Fragile X syndrome is associated with low ovarian reserve and poor ovarian response. The aim of this study was to investigate whether CGG repeats on the fragile X mental retardation 1 (FMR1) gene have predictive value for ovarian response to stimulation with gonadotrophins and for clinical outcome in our oocyte donation program. METHODS Oocyte donor candidates were selected accordi...

The desired objective of controlled ovarian stimulation (COS) is to allow the growth of a cohort of follicles and to facilitate the recovery of a large number of fertilizable oocytes. However, poor responders with low ovarian reserve often fail to respond adequately despite the maximal dose of gonadotropins administered, with the results that the number as well as quality of oocytes harvested m...

To review treatment options for poor-responding patients who are undergoing infertility treatment. Review article and case studies.A comprehensive determination of potential ovarian response for the poor-responding patient is important in the individualization of treatment options for these patients. Treatment options include both the microdose flare leuprolide acetate and GnRH antagonist stimu...
