INTRODUCTION: Recurrent miscarriage (RM), defined by three or more consecutive losses during the first trimester of pregnancy, affects 1%-2% of fertile couples. Standard investigations fail to reveal any apparent cause in ~50% of couples. However, on the basis of animal models and clinical studies, several hypotheses have been put forward concerning underlying mechanisms of RM: altered ovarian reserve, progesterone defect, thrombotic and/or endothelial dysfunction and immunological disturbances...

Granulosa cell tumor (GCT) is a majorly observed ovarian tumor in female dogs. It is essential to diagnose GCT in its initial phase before any symptoms occur, as histological and physiological differences may be observed based on the evolution of this neoplasia. This study aimed to analyze the anatomic histopathology of GCT in its initial stage, with findings of ovaries not yet with the suspicion of neoplasms in the Canis familiaris. A sample including 55 ovaries that presented GCT in 40 female dogs. The histopathological analysis was performed considering the intensity of pleomorphism, vascularization, and inflammatory infiltrate...

BACKGROUND: It has been proposed that ovarian sickling and/or iron overload in women with sickle cell disease (SCD) could contribute to gonadal dysfunction, but there are very few published studies. We hypothesised that the above phenomena might impair ovarian reserve. METHODS: A total of 50 SCD patients were case-matched by age, ethnicity, and presence of regular cycles (28±5 days) with 73 patients without a known haemoglobinopathy who required anti-Müllerian hormone (AMH) assessment in a gynaecology clinic...

BACKGROUND: Global consumption of protein per capita is rising, while rates of infertility are increasing. However, a clear relationship between protein intake and reproductive health has not been demonstrated. The activation of the quiescent primordial follicles is the first step of folliculogenesis, and their activation must be tightly controlled to prevent premature exhaustion of the ovarian follicular reserve. METHODS: The primordial follicle reserve of wild-type or liver-specific ablation of fibroblast growth factor 21 (FGF21) in mice, subjected to limited or excessive protein diets or oral gavage test, were detected in vivo...

Anophelinae mosquitoes are vectors of human malaria, a disease that infects hundreds of millions of people and causes almost 600,000 fatalities annually. Despite their medical importance, laboratory studies on key aspects of Anophelinae reproductive biology have been limited, and in particular, relatively little is known about the role of juvenile hormone (JH) in the control of female reproduction. The study presented here attempts to fill a gap of knowledge in our understanding of the JH control of ovarian development in female Anophelinae mosquitoes, using Anopheles albimanus as a model...

BACKGROUND: Despite being born with a significant number of primordial cells which representing the ancestor cells of the germ-line, women experience a depletion of ovarian reserve and sub-fertility mid-way into their healthy lives. The poor ovarian response is a substantial limiting factor amplified with higher maternal age and associated with a considerably lower likelihood of pregnancy. METHODS: A present analytical prospective cross-sectional study was conducted to explore whether infertile women below the age of 40 years have low ovarian reserve than fertile women of same age, assessed by Antral follicle count (AFC) and anti-Müllerian hormone (AMH), at tertiary care infertility center: Lahore Institute of Fertility and Endocrinology, Hameed Latif Hospital...

BACKGROUND: Ovarian endometrioma is a frequent manifestation of endometriosis in women of reproductive age. Several issues related to its space occupying effects, local reactions and surgical removal continue to be actively debated today. The impact of ovarian endometrioma per se on ovarian reserve is still controversial and the effect of ovarian surgery is still actively discussed. Furthermore, the optimal biomarker of ovarian reserve estimation in women with ovarian endometrioma is still under examination...

Inflammation plays a crucial role in the pathogenesis of cancer with tumor necrosis factor alpha (TNFα) as a key mediator. Recently, spermatogenesis-associated protein 2 (SPATA2) was identified as a TNF receptor modulator which is required for TNF-induced inflammation and apoptosis. The available data on TNFα in ovarian cancer (OC) are inconsistent and SPATA2 is completely uncharacterized in tumorigenesis. We analyzed expression of SPATA2 and TNFA by quantitative real-time PCR in tissues of 171 patients with low grade serous (LGSOC), high grade serous (HGSOC), endometrioid and clear cell OC compared to 28 non-malignant control tissues...

STUDY QUESTION: Do the stage and grade of malignancy affect the fertility preservation outcome in females? SUMMARY ANSWER: Patients with high-grade cancer have a decreased number of retrieved mature oocytes and cryopreserved embryos. WHAT IS KNOWN ALREADY: Cancer has local and systemic effects on the host. The effects of cancer spread and aggressiveness on the ovarian function and stimulation response remain unclear. STUDY DESIGN, SIZE, DURATION: Retrospective cohort study evaluating data of all fertility preservation treatment cycles among women with cancer at the reproductive unit of the McGill University Health Centre in the period from 2008 to 2017...

This review summarizes studies we conducted to test the hypothesis that size of the ovarian reserve (number of healthy follicles and oocytes in ovaries) positively impacts ovarian function and fertility in cattle. Key results, primarily in Bos Taurus dairy cattle, show that antral follicle count (AFC) during follicular waves is highly variable between individuals, but very highly repeatable within individuals. Cycling heifers with low (≤ 15 follicles ≥ 3 mm, ~20% of a herd) vs a high AFC (≥ 25, ~20% of a herd) have a smaller ovarian reserve, higher FSH but lower AMH, androstenedione, estradiol and progesterone concentrations...

A 43-year-old woman with an associated history of gynecological pathology and breast cancer with only one cryopreserved embryo wished to be a mother. Several factors that influenced the success of the pregnancy in this case were analyzed. Favorable factors included: triple positive breast cancer [positive hormone receptors and positive human epidermal growth factor receptor 2], which is more hormosensitive and chemosensitive; absence of metastasis; correct endometrium preparation; and the patient's optimistic attitude and strict health habits...

BACKGROUND: In assisted reproductive technology, prediction of treatment failure remains a great challenge. The development of more sensitive assays for measuring anti-Müllerian hormone (AMH) has allowed for the possibility to investigate if a lower threshold of AMH can be established predicting very limited or no response to maximal ovarian stimulation. METHODS: A prospective observational multicenter study of 107 women, < 40 years of age with regular menstrual cycle and serum AMH levels ≤ 12 pmol/L, treated with 300 IU/day of HP-hMG in a GnRH-antagonist protocol...

Background: Anti-Mϋllerian hormone (AMH) plays an important role regulating ovarian sensitivity to follicle-stimulating hormone and luteinizing hormone in folliculogenesis. Anti-Mϋllerian hormone is well established as a biomarker of ovarian reserve but may also have utility in predicting pregnancy outcomes. Few studies have described AMH levels in pregnancy and, among those that have, most have used cross-sectional study designs and are limited to participants seeking fertility treatment...

BACKGROUND: Gonadal dysfunction is one of the major late complications after cancer diagnosis and treatment. The best markers of ovarian reserve in clinical practice are antral follicle count (AFC) and ovarian volume. We aimed to study the prevalence of premature ovarian insufficiency (POI) and evaluate anti-Müllerian hormone (AMH) and other serum markers for ovarian function in adult women who were childhood cancer survivors (CCS) in comparison with a control group. MATERIAL AND METHODS: Altogether, 167 female CCS were compared to 164 matched controls...

The number of antral follicles counted by ultrasound (AFC) is associated with fertility in cattle. Cows with higher follicle count (HFC) have higher performance in reproductive-assisted technologies than cows with lower follicle count (LFC). In this study, we aimed to define the preantral follicle count by histology and to identify differentially expressed genes (DEGs) using a microarray in Nelore and Angus heifers with HFC and LFC. The ovaries of each animal were scanned with an ultrasound device 12-24 hours after estrus...
