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...

It is known that LLLT has beneficial effects on several pathological conditions including wound healing, pain and inflammation. LLLT modulates biological processes, including cell proliferation, apoptosis and angiogenesis. In the present study, we examined the effect of local application of LLLT on follicular dynamics, ovarian reserve, AMH expression, progesterone levels, apoptosis, angiogenesis, and reproductive outcome in adult mice. LLLT (200 J/cm2 ) increased the percentage of primary and preantral follicles, whilst decreasing the percentage of corpora lutea compared to control ovaries...

Epithelial ovarian cancer (EOC) is one of the major malignant cancers with high rates of early metastasis in which regulatory T cells (Tregs) play an important role. Tregs suppress immune responses and promote the development of tumours in patients with EOC. However, the underlying mechanisms remain unclear. In this study, we found higher levels of CD4+ CD25high CD127low Tregs in patients with EOC than in patients with benign ovarian tumours and healthy donors. The immune inhibitory effect of Tregs functions by maintaining high levels of immunosuppressive cytokines in EOC...

Natural Cycle IVF (NC-IVF) with and without modifications is being increasingly performed. NC-IVF and conventional gonadotropin-stimulated IVF (cIVF) should not be understood as competing treatments, but as complementary treatments with different target groups and to some extent other indications. NC-IVF is particularly interesting for couples who wish to save money, wish a treatment with as few risks as possible and for women who would like to avoid selection and cryopreservation of embryos. NC-IVF therefore contributes to the concept of individualized and patient-oriented therapy...

Profitability of beef cattle producers can be directly tied to the productive lifespan of a cow. Management decisions influencing heifer nutrition and reproduction play a key role in establishing heifer fertility and longevity. Altering feeding strategies to utilize compensatory growth has been reported to have a positive influence on fertility during the first breeding season; however, there are discrepancies in the literature as to the impact this strategy may have on the proportion of heifers attaining puberty prior to entering their first breeding season...

In the present study we investigated the temporal relationship between angiogenic and anti-angiogenic vascular endothelial growth factor isoforms (VEGFxxxa and VEGFxxxb respectively), the receptors VEGFR1 and VEGFR2, their soluble forms, and the kinases and the splicing factors regulating the synthesis of VEGF isoforms in healthy and atretic antral follicles. The results show a higher (P<0.05) mRNA expression of VEGF120a, VEGF164a and VEGF120b in healthy than in atretic follicles, but the mRNA expression of VEGF164b was not detected...

Hypo-responsiveness to controlled ovarian stimulation is an undervalued topic in reproductive medicine. This phenomenon manifests as a low follicles output rate (FORT) with a discrepancy between the relatively low number of pre-ovulatory follicles which develop following ovarian stimulation as compared to the number of antral follicles available at the start of stimulation. The pathophysiology mechanisms explaining the ovarian resistance to gonadotropin stimulation are not fully understood, but the fact that both hypo-responders and normal responders share similar phenotypic characteristics suggests a genotype-based mechanism...

The evaluation of intra-tumour heterogeneity (ITH) from a transcriptomic point of view is limited. Single-cell cancer studies reveal significant genomic and transcriptomic ITH within a tumour and it is no longer adequate to employ single-subtype assignment as this does not acknowledge the ITH that exists. Molecular assessment of subtype heterogeneity (MASH) was developed to comprehensively report on the composition of all transcriptomic subtypes within a tumour lesion. Using MASH on 3,431 ovarian cancer samples, correlation and association analyses with survival, metastasis, and clinical outcomes were performed to assess the impact of subtype composition as a surrogate for ITH...

AIMS: Ovarian endometrioid carcinoma (EC) generally has a good prognosis. Adjuvant chemotherapy can be spared in low stage disease, but prognostic biomarkers are needed to refine the treatment threshold. Wnt/β-catenin signaling is commonly altered in EC. We examined immunohistochemical expression of nuclear β-catenin and CDX2, both are mediators of the Wnt pathway, as prognostic biomarkers for EC. METHODS AND RESULTS: We evaluated two ovarian EC cohorts, discovery set (N=183) and validation set (N=174), with ovarian cancer-specific survival (OCSS) as the primary end-point...

Circulating anti-müllerian hormone (AMH) and antral follicle count (AFC) are the best predictors of IVF outcomes. However, in extreme low AMH range especially for young patients, AMH prediction power loose its specificity to give real idea of pregnancy chance with IVF treatments and good prognosis of an extremely reduced ovarian reserve and expected poor response. Indeed, this retrospective study was conducted to evaluate IVF outcomes in patients following IVF-ICSI program with extremely low AMH levels (≤0...

Anti-Müllerian hormone (AMH) is a useful biomarker to predict the ovarian response to controlled ovarian stimulation (COS) for IVF. However, currently there is a lack of evidence for the role of ovarian reserve markers when there is no need of COS. The aim of this study was to evaluate the usefulness of AMH to predict the outcomes of donor sperm insemination cycles in non-infertile women. A retrospective study including 139 healthy women, who underwent 348 intrauterine insemination (IUI) cycles with donor sperms under the stimulated or natural cycles, was conducted...
