RESEARCH QUESTION: Does ovarian reserve and ovarian response to ovarian stimulation in women with cancer undergoing oocyte vitrification for fertility preservation vary according to the type of malignancy? DESIGN: Retrospective cohort study including 105 women aged between 18 and 40 years, who were referred for fertility preservation (oocyte vitrification) between 2013 and 2016. The women were divided into three groups: breast cancer, lymphoma or other cancer. All of them had been recently diagnosed with cancer, with gonadotoxic treatment scheduled, and had oocyte vitrification after ovarian stimulation with antagonist protocol...

The aim of this study was to investigate the impact of anti-thyroid peroxidase antibodies (Anti-TPO) on the in vitro fertilization and embryo transfer (IVF-ET) outcome in women with poor ovarian reserve but normal thyrotropin levels. A total of 300 patients with poor ovarian reserve undergoing ICSI cycle from April 2015 to December 2017 were analyzed retrospectively. Subjects were divided into two groups: Group 1: Women with early ovarian aging, Group 2: Women with age related poor ovarian reserve. All subjects underwent anti-thyroid peroxidase antibody (anti-TPO) analysis...

PURPOSE OF REVIEW: Preimplantation genetic testing for aneuploidy (PGT-A) has been demonstrated to improve implantation and pregnancy rates and decrease miscarriage rates over standard morphology-based embryo selection. However, there are limited data on its efficacy in patients with diminished ovarian reserve or a poor response to stimulation who may have fewer embryos to select amongst. RECENT FINDINGS: Early findings demonstrate that PGT-A reduces the miscarriage rate and decreases the time to delivery in poor responders...

Background: Assessment of ovarian reserve before an in vitro fertilization cycle (IVF) is one among the many factors that predicts a successful cycle. Individualized protocol based on ovarian reserve is designed to optimize the pregnancy outcome without compromising the patient safety. Although authors have shown that anti-Mullerian hormone-tailored (AMH) protocols have reduced the treatment burden and improved pregnancy rates, a few others have questioned its efficacy. Aims: The aim of this study was to decide whether the AMH-tailored protocol or the conventional protocol better decides IVF outcomes...

We aimed to investigate the different effects of low oxygen (5% O2 ) and atmospheric oxygen (20% O2 ) on in vitro fertilization for older poor ovarian responders (PORs). We selected 1080 older PORs who met two criteria: (i) advanced maternal age (≥40) and (ii) an abnormal ovarian reserve test. All the patients used the ultra-short term protocols with GnRH agonist and recombinant FSH for controlled ovarian hyperstimulation (COH). About 506 cycles were performed in the incubators with 5% O2 and 574 cycles were performed in the incubators with 20% O2 ...

PURPOSE OF REVIEW: The management and treatment of patients with poor ovarian response is still a controversial issue in IVF. Increasing evidences demonstrate that the number of oocytes retrieved after a controlled ovarian stimulation (COS) greatly influences the clinical outcome in terms of cumulative live birth per started cycle. For this reason, any COS should aim to optimize the number of oocytes according to the ovarian reserve of the patient. The aim of this review is to provide an overview of new strategies proposed to manage poor responders according to the novel POSEIDON classification...

Ovarian clear cell carcinoma (OCCC) is a type of epithelial ovarian cancer that is strongly associated with endometriosis, resistance against conventional chemotherapy and thus poorer prognosis. The expression of inhibitory member of the ASPP family proteins (iASPP) and Polo-like kinase (PLK)1 were significantly higher in OCCC compared to benign cystadenomas and endometriosis. Both protein expressions were found to correlate with chemoresistance in patients with OCCC while high iASPP expression alone was significantly associated with a poor patient survival...

AIMS: Gynandroblastoma is a rare ovarian sex cord-stromal tumor characterized by the presence of both male (Sertoli and/or Leydig cells) and female (granulosa cells) components. We investigated the mutational status of DICER1, FOXL2 and AKT1 genes at hotspot regions that are known to be the key driving events in the development of Sertoli-Leydig cell tumor (SLCT), adult granulosa cell tumor (aGCT) and juvenile granulosa cell tumor (jGCT), respectively, to gain insights into the molecular pathogenesis of gynandroblastoma...

Controlled ovarian stimulation with gonadotrophins is an essential part of in-vitro fertilization treatment. The aim is to produce an optimum number of oocytes to maximize success in the safest possible way. Pituitary downregulation with a gonadotrophin-releasing hormone agonist and stimulation with recombinant follicle-stimulating hormone is used widely. However, there are many different protocols in use with little evidence to determine the optimum regimen. Markers of ovarian reserve and patient characteristics are used in an attempt to individualize treatment...

Advanced ovarian clear cell carcinoma (OCCCa) shows poor prognosis with chemoresistance, which is associated with epithelial-mesenchymal transition (EMT)/cancer stem cell (CSC) features. The left-right determination factor (LEFTY), a novel member of the TGF-β superfamily, is a marker of stemness. Here we focused on the functional roles of LEFTY in OCCCas. OCCCa cell lines that were cultured in STK2, a serum-free medium for mesenchymal stem cells, or treated with TGF-β1 underwent morphological changes toward an EMT appearance, along with increased expression of LEFTY and Snail...

BACKGROUND: Management of women with reduced ovarian reserve or poor ovarian response (POR) to stimulation is one of the major challenges in reproductive medicine. The primary causes of POR remain elusive and oxidative stress was proposed as one of the important contributors. It has been suggested that focus on the specific subpopulations within heterogeneous group of poor responders could assist in evaluating optimal management strategies for these patients. This study investigated the effect of anti-oxidant treatment with coenzyme Q10 (CoQ10) on ovarian response and embryo quality in young low-prognosis patients with POR...

PURPOSE: Few clinical options for fertility preservation are available to females with cancer, and data about clinical outcomes is limited. Potential supplementary approaches to fertility preservation include retrieval of immature oocytes followed by in vitro maturation (IVM) and storage. The aim of this study was to evaluate post-thawing outcomes of immature oocytes collected both by transvaginal aspiration and from excised ovarian tissue. METHODS: We conducted a retrospective cohort study of patients treated in a single tertiary center...

Overexpression of fatty acid synthase (FASN), a key regulator of the de novo synthesis of fatty acids, has been demonstrated in a variety of cancers and is associated with poor prognosis and increased multidrug resistance. Inhibition of FASN with the anti-obesity drug orlistat has been shown to have significant anti-tumorigenic effects in many cancers, notably breast and prostate. In this study, we investigated whether FASN inhibition using orlistat is an effective adjunctive treatment for ovarian cancers that have become platinum resistant using a cisplatin-resistant ovarian tumour xenograft model in mice...

BACKGROUND: Highly Individualized Egg Retrieval (HIER), defined as age-specific early oocyte retrieval (ER), has been demonstrated to avoid premature luteinization in women ≥43. We here investigated whether HIER also applies to younger women with premature ovarian aging (POA), and what best lead follicle size should be for administration of ovulation-triggers. METHODS: Fifty-six women ≥43, and 37 POA patients underwent IVF cycles. Granulosa cells (GCs) were isolated, cultures were established, RNA was extracted and real-time PCR analyses performed, with gene expressions at mRNA level investigated for FSH receptor (FSHR), luteinizing hormone receptor (LHCPR), P450 aromatase (CYP19a1) and progesterone receptor (PGR)...

Controlled ovarian stimulation with subsequent multi-follicular development continues to be a keystone in ART. Evidence supports an individualized approach to ovarian stimulation, usually involving combinations of ovarian reserve tests, body mass index and age to tailor the exogenous gonadotropin dose, and potentially adjuvant treatment aiming for high safety and a shortening of time to live birth. While stimulation and trigger concepts have been developed successfully in normo- and hyperresponder patients, the poor responder patient remains difficult to manage...

It has been more than 15 years since the measurement of serum anti-Müllerian hormone (AMH) first allowed the quantitative assessment of ovarian reserve. Meanwhile, the clinical implication of serum AMH has been expanding. The measurement of serum AMH has been applied in various clinical fields, including assisted reproduction, menopause, reproductive disorders and assessment of ovarian damage/toxicity. Well-known findings about the usefulness of serum AMH revealed by numerous studies executed in the early era include decline with aging, a good correlation with oocyte yield in assisted reproduction, upregulation in polycystic ovarian syndrome and a decrease on ovarian surgery and toxic treatment...

Platelets modulate clinically relevant yet incompletely understood tissue regeneration processes, and platelet rich plasma (PRP) has been previously used with some success in various non-reproductive medical contexts. Here, we extended PRP application to ovarian tissue with a view to document impact on ovarian reserve among women attending for infertility treatment. PRP was freshly isolated from patients (n= 4) with diminished ovarian reserve as determined by at least one prior IVF cycle canceled for poor follicular recruitment response or estimated by serum AMH and/or FSH, no menses for ≥1 year...

Mucinous type of epithelial ovarian cancer (MuOC) is a unique subtype with a poor survival outcome in recurrent and advanced stages. The role of type-specific epigenomics and its clinical significance remains uncertain. We analyzed the methylomic profiles of 6 benign mucinous adenomas, 24 MuOCs, 103 serous type of epithelial ovarian cancers (SeOCs) and 337 nonepithelial ovarian cancers. MuOC and SeOC exhibited distinct DNA methylation profiles comprising 101 genes, 81 of which exhibited low methylation in MuOC and were associated with the response to glucocorticoid, ATP hydrolysis-coupled proton transport, proteolysis involved in the cellular protein catabolic process and ion transmembrane transport...
