ETHNOPHARMACOLOGICAL RELEVANCE: Kuntai capsule, a traditional Chinese medicine, has been widely used for the clinical treatment of menopausal syndrome. However, its mechanisms remain poorly understood. Considering that aging ovaries are the primary cause of menopause, this study was designed to investigate the effects and mechanisms of Kuntai capsule on ovarian function in a novel mice model with accelerated aging ovaries. MATERIALS AND METHODS: Seventy-five female C57BL/6 mice were chosen for this study...

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...

Family history of cancer is a well-known risk factor but the role of family history in survival is less clear. The aim of this study was to investigate the association between family history and cancer survival for the common cancers in Sweden. Using the Swedish population-based registers, patients diagnosed with the most common cancers were followed for cancer-specific death during 1991-2010. We used multivariate proportional hazards (Cox) regression models to contrast the survival of patients with a family history of cancer (individuals whose parent or sibling had a concordant cancer) to the survival of patients without a family history...

The reproductive biology of South American freshwater stingrays (family Potamotrygonidae) is still poorly studied compared to other marine species. In the present study, we examined the gross anatomy and histology of six species of potamotrygonids from the Amazon basin and described the structural asymmetry of the ovaries and their relationship between ovarian/uterine fecundities. Stereological techniques were used to quantify the volume of ovarian and epigonal organ tissue associated with the left and right sides of the Potamotrygon wallacei, a recently described species, locally known as the cururu ray...

Measurements of ovarian reserve play an important role in predicting the clinical results of assisted reproductive technology (ART). The ideal markers of ovarian reserve for clinical applications should have high specificity in order to determine genuine poor responders. Basal follicle-stimulating hormone levels, antral follicle count, and serum anti-Müllerian hormone (AMH) levels have been suggested as ovarian reserve tests that may fulfill this requirement, with serum AMH levels being the most promising parameter...

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)...

In poor prognosis patients undergoing in vitro fertilization, advance determinations of likely oocyte yields are especially important since oocyte numbers to large degree determine in vitro fertilization cycle outcomes. Based on baseline follicle stimulating hormone and anti-müllerian hormone levels at time of initial presentation, we here, therefore, determined at all ages the probabilities of obtaining 1-≥5 oocytes in a retrospective analysis of 1554 consecutive patients undergoing in vitro fertilization cycles at an academically affiliated private fertility center...

STUDY QUESTION: Can a nomogram be used to predict the individual probability of live birth (LB) in women with borderline ovarian tumours (BOTs) receiving primary fertility-sparing surgery? SUMMARY ANSWER: A nomogram built according to the woman's age, histological subtype (serous versus mucinous), type of ovarian surgical treatment and FIGO stage can accurately predict the probability of LB in women with BOT. WHAT IS KNOWN ALREADY: Current prediction models determine the probability of pregnancy after medically assisted reproduction (MAR) and form the basis of patient counselling to guide the decision as to whether to consider in vitro fertilization but do not take into account prediction of the LB rate...

Ovarian endometrioma is one of the important causes of poor ovarian reserve and up to half of them have been recurred. However, the treatment for recurrence prevention has limited efficiency and repeated surgery makes worsen the ovarian reserve. To find better management for recurrence prevention, we investigated risk factors and biomarkers for the recurrent endometriomas. The medical records of women with history of surgical dissection for ovarian endometrioma were collected. After exclusion of the cases with concurrent hysterectomy, been menopaused during follow-up, incomplete medical record, and loss of follow-up, a total of 134 women were enrolled...

PURPOSE: Chronic pelvic pain (CPP) in the presence of dilated and refluxing pelvic veins is often described as pelvic congestion syndrome (PCS), although the causal relationship between pelvic vein incompetence and CPP has not been established. Percutaneous embolization is the principal treatment for PCS, with high success rates cited. This study was undertaken to systematically and critically review the effectiveness of embolization of incompetent pelvic veins. MATERIALS AND METHODS: A comprehensive search strategy encompassing various terms for pelvic congestion, pelvic pain, and embolization was deployed in 17 bibliographic databases, with no restriction on study design...

Poor ovarian reserve (POR) is an important limiting factor for the success of any treatment modality for infertility. It indicates a reduction in quantity and quality of oocytes in women of reproductive age group. It may be age related as seen in advanced years of reproductive life or may occur in young women due to diverse etiological factors. Evaluating ovarian reserve and individualizing the therapeutic strategies are very important for optimizing the success rate. Majority or women with POR need to undergo in vitro fertilization to achieve pregnancy...

INTRODUCTION: Fertility is referred to the capability for having offspring and can be evaluated by fertility rate. Women's fertility is strictly dependent on individual's age. The fertility peak occurs in the early 20s, and it starts to decline in the third and fourth decades of life (falling sharply after age 35). AIM: The aim of this work is to review the available data concerning fertility in women of late reproductive age, especially the role of serum anti-Müllerian hormone (AMH) levels...

HOX genes are vital for all aspects of mammalian growth and differentiation, and their dysregulated expression is related to ovarian carcinogenesis. The aim of the current study was to establish the prognostic value of HOX dysregulation as well as its role in platinum resistance. The potential to target HOX proteins through the HOX/PBX interaction was also explored in the context of platinum resistance. HOX gene expression was determined in ovarian cancer cell lines and primary EOCs by QPCR, and compared to expression in normal ovarian epithelium and fallopian tube tissue samples...

Granulosa cells (GCs) are tightly associated with fertility and the fate of ovarian follicles. Mitochondria are the central executers of apoptosis. However, the genetic basis underlying mitochondrial modulation in GCs during the ovarian development is poorly understood. Here, CRISPR/Cas9-mediated genetic screening was used to identify genes conferring mitochondrial metabolism in human GCs. The results uncovered roles for several tumor suppressors, including HBP1, in the augmentation of mitochondrial function...

BACKGROUND: Low testosterone (T), whether due to ovarian and/or adrenal insufficiency, usually results in poor follicle maturation at small growing follicle stages. The consequence is a phenotype of low functional ovarian reserve (LFOR), characterized by poor granulosa cell mass, low anti-Müllerian hormone and estradiol but rising follicle stimulating hormone. Such hypoandrogenism can be of ovarian and/or adrenal origin. Dehydroepiandrosterone sulfate (DHEAS) is exclusively produced by adrenals and, therefore, reflects adrenal androgen production in the zona reticularis...
