STUDY QUESTION: In subfertile women with poor ovarian reserve undergoing IVF does a mild ovarian stimulation strategy lead to comparable ongoing pregnancy rates in comparison to a conventional ovarian stimulation strategy? SUMMARY ANSWER: A mild ovarian stimulation strategy in women with poor ovarian reserve undergoing IVF leads to similar ongoing pregnancy rates as a conventional ovarian stimulation strategy. WHAT IS KNOWN ALREADY: Women diagnosed with poor ovarian reserve are treated with a conventional ovarian stimulation strategy consisting of high-dose gonadotropins and pituitary downregulation with a long mid-luteal start GnRH-agonist protocol...

BACKGROUND: Growing studies have demonstrated that dehydroepiandrosterone (DHEA) may improve fertility outcomes in poor ovarian responders (PORs). The aim of this study was to compare clinical outcomes and cumulus cell (CC) expression before and after DHEA treatment in PORs undergoing in vitro fertilization (IVF) cycles. METHODS: Six patients with poor ovarian response were enrolled in the study according to Bologna criteria. DHEA was supplied at least 2 months before patients entered into the next IVF cycle...

Chromosomal aneuploidy is responsible for a significant proportion of pregnancy failures, whether conceived naturally or through in vitro fertilization (IVF). In an effort to improve the success rate of IVF, screening embryos for aneuploidy - or pre-implantation genetic screening (PGS) - has been proposed as a means of ensuring only euploid embryos are selected for transfer. Early PGS approaches were based on fluorescence in situ hybridization testing, and have been shown not to improve live birth rates. Recent developments in genetic testing technologies - such as next-generation sequencing and quantitative polymerase chain reaction, coupled with embryo biopsy at the blastocyst stage - have shown promise in improving IVF outcomes, but they remain to be validated in adequately powered, prospective randomized trials...

BACKGROUND: Age and increased FSH serum level in women are prognosis criteriae associated with decreased fertility. OBJECTIVE: The aim of this study was to investigate whether age-specific FSH concentration can be a predictor of the outcome of ovarian stimulation in women undergoing IVF. METHODS: A total of 676 women undergoing their first IVF cycle over a 3-year period were included in this retrospective cohort study. Patients were grouped according to age (< or ≥  38 years), and within each age range, patients were grouped into bFSH quartiles (< or ≥  9...

One in 10 women reach menopause before they are 45 years of age, and 1 in 100 before 40. In most cases, poor ovarian response to gonadotrophins is a result of poor ovarian reserve. An early menopause is associated with long-term health risks. Identifying women at risk may allow appropriate measures to be instigated early. Women aged <40 years treated in the Aberdeen Fertility Centre between 1998 and 2002 were identified. Those with poor response to an age appropriate dose of gonadotrophins (obtaining ≤3 eggs or had cycle cancelled) after exclusion of hypothalamic insufficiency, or whose cycle was cancelled due to poor response were age matched with good responders (6-15 eggs)...

The aim of this review is to analyze the relationship between preovulatory progesterone (P) rise and in vitro fertilization (IVF) pregnancy outcomes. It also investigates the sources and effects of rises in progesterone levels, including the underlying mechanisms and potential strategies in preventing its elevation during ovarian stimulation. Progesterone is produced in the early follicular phase in the adrenal gland, which shifts toward the ovaries prior to ovulation. Several factors contribute to the etiology of P level increase including the number of multiple follicles, the overdose of gonadotropins and poor ovarian response...

BACKGROUND: Gonadotrophin-releasing hormone (GnRH) antagonists can be used to prevent a luteinizing hormone (LH) surge during controlled ovarian hyperstimulation (COH) without the hypo-oestrogenic side-effects, flare-up, or long down-regulation period associated with agonists. The antagonists directly and rapidly inhibit gonadotrophin release within several hours through competitive binding to pituitary GnRH receptors. This property allows their use at any time during the follicular phase...

Single nucleotide polymorphisms (SNPs) in the growth differentiation factor (GDF)‑9 gene are associated with premature ovarian failure, insufficient ovarian stimulation and a poor in vitro fertilization (IVF) score in women with diminished ovarian reserve. The aim of the present study was to assess the effect of C447T (rs254286) and G546A (rs10491279) SNPs on ovary stimulation response, oocyte quality, fertilization rate and outcome of clinical pregnancy in an infertile population of Polish females (n=86) treated with IVF...

The relationship between FMR1 CGG premutation status and decreased ovarian responsiveness is well established. The association between FMR1 CGG repeat number in the currently defined normal range (less than 45 repeats) and ovarian reserve, however, is controversial. This retrospective study examined whether variation in CGG repeat number in the normal range was associated with markers of ovarian response in IVF cycles. The first IVF cycle of 3006 patients with FMR1 CGG repeat analysis was examined. Only patients carrying two alleles with less than 45 CGG repeats were included for analysis...

Poor ovarian response to controlled ovarian stimulation (COS) is one of the most critical factors that substantially limits the success of assisted reproduction techniques (ARTs). Natural and modified natural cycle IVF are two options that could be considered as a last resort. Blocking gonadotropin-releasing hormone (GnRH) actions in the endometrium via GnRH receptor antagonism may have a negative impact on endometrial receptivity. We analysed IVF outcomes in 142 natural (n = 30) or modified natural (n = 112) IVF cycles performed in 82 women retrospectively...

BACKGROUND: A substantial minority of women undergoing IVF will under-respond to controlled ovarian hyperstimulation. These women-so-called 'poor responders'-suffer persistently reduced success rates after IVF. Currently, no single intervention is unanimously accepted as beneficial in overcoming poor ovarian response (POR). This has been supported by the available research on POR, which consists mainly of randomized controlled trials (RCTs ) with an inherent high-risk of bias. The aim of this review was to critically appraise the available experimental trials on POR and provide guidance towards more useful-less wasteful-future research...
