Value of PGT-A when only one or two blastocysts are obtained: propensity-score matching and cost-effectiveness study.

Objective: To compare the effectiveness and cost of in-vitro fertilization (IVF) with or without preimplantation genetic testing for aneuploidy (PGT-A) when only one or two blastocysts are obtained.

Methods: A dataset was gathered from 1829 patients including 368 non-PGT-A and 1461 PGT-A cycles with one or two blastocysts obtained, between April 2013 and July 2022. Patients were matched 1:1 by propensity-score matching for maternal age, number of metaphase-II oocytes inseminated and number of blastocysts obtained, achieving a database of 242 patients per group.

Private versus funded infertility care: not a challenge but a call for cooperation.

Private medical care has significantly contributed to the advancement of various medical fields. The birth of private IVF groups in the 1990s led to improvements in stimulation protocols, embryo culture, intracytoplasmic sperm injection, vitrification and preimplantation genetic testing. However, infertility is often misunderstood as a disease, leading to low birth rates and a lack of awareness among the general population.

A multicycle approach through DuoStim with a progestin-primed ovarian stimulation (PPOS) protocol: a valuable option in poor prognosis patients undergoing PGT-A.

Purpose: This study is to evaluate the effectiveness of a PPOS protocol in poor prognosis patients undergoing IVF with DuoStim and PGT-A versus the conventional protocol with GnRH antagonist.

Methods: Retrospective cohort study encompassing 444 couples obtained matching one PPOS-DuoStim with two antagonist-DuoStim cycles at a private IVF center between 2020 and 2023 (average maternal age: 40 years, average cumulus-oocyte complexes collected after the first stimulation: 5). The study was powered to exclude a two-sided different euploid blastocyst rate per MII oocytes (EBR per MII) in the two groups (alpha = 0.

ICSI and PGT-A in PCOS phenotype-D patients: a matched case-control study versus idiopathic infertile women.

Purpose: To assess oocyte competence and embryo chromosomal constitution in phenotype-D PCOS women undergoing ICSI for PGT-A at the blastocyst stage.

Methods: Retrospective study at a private IVF center. In the period 2013-2021, 58 naïve phenotype-D PCOS women (i.

Extracellular vesicles secreted by cumulus cells contain microRNAs that are potential regulatory factors of mouse oocyte developmental competence.

The role of cumulus cells (CCs) in the acquisition of oocyte developmental competence is not yet fully understood. In a previous study, we matured cumulus-denuded fully-grown mouse oocytes to metaphase II (MII) on a feeder layer of CCs (FL-CCs) isolated from developmentally competent (FL-SN-CCs) or incompetent (FL-NSN-CCs) SN (surrounded nucleolus) or NSN (not surrounding nucleolus) oocytes, respectively. We observed that oocytes cultured on the former could develop into blastocysts, while those matured on the latter arrested at the 2-cell stage.

The metrics maze in science: navigating academic evaluation without journalistic pressures.

In recent years a troubling trend has emerged in the medical research field, notably in reproductive medicine, manifesting an increased emphasis on quantity over quality in articles published. The pressure to collect copious publication records risks compromising meticulous expertise and impactful contributions. This tendency is exemplified by the rise of 'hyper-prolific researchers' publishing at an extraordinary rate (i.

Can Digital Technologies Be Useful for Weight Loss in Individuals with Overweight or Obesity? A Systematic Review.

Digital technologies have greatly developed and impacted several aspects of life, including health and lifestyle. Activity tracking, mobile applications, and devices may also provide messages and goals to motivate adopting healthy behaviors, namely physical activity and dietary changes. This review aimed to assess the effectiveness of digital resources in supporting behavior changes, and thus influencing weight loss, in people with overweight or obesity.

Role of thyroid stimulating hormone in the maintenance and functioning of the human corpus luteum.

Purpose: To evaluate the impact of high thyroid stimulating hormone (TSH) levels on human granulosa-luteal (hGL) cells.

Methods: hGL cells were isolated from follicular aspirates derived from patients undergoing IVF treatment without any thyroid disorder (serum TSH 0.5-2 mU/L).

Systematic Review and Meta-Analysis of Dietary Interventions and Microbiome in Phenylketonuria.

Inborn errors of metabolism (IEMs) comprise a diverse group of monogenic disorders caused by enzyme deficiencies that result either in a toxic accumulation of metabolic intermediates or a shortage of essential end-products. Certain IEMs, like phenylketonuria (PKU), necessitate stringent dietary intervention that could lead to microbiome dysbiosis, thereby exacerbating the clinical phenotype. The objective of this systematic review was to examine the impact of PKU therapies on the intestinal microbiota.

Innovative Strategies for Fertility Preservation in Female Cancer Survivors: New Hope from Artificial Ovary Construction and Stem Cell-Derived Neo-Folliculogenesis.

Recent advances in anticancer treatment have significantly improved the survival rate of young females; unfortunately, in about one third of cancer survivors the risk of ovarian insufficiency and infertility is still quite relevant. As the possibility of becoming a mother after recovery from a juvenile cancer is an important part of the quality of life, several procedures to preserve fertility have been developed: ovarian surgical transposition, induction of ovarian quiescence by gonadotropin-releasing hormone agonists (GnRH-a) treatment, and oocyte and/or ovarian cortical tissue cryopreservation. Ovarian tissue cryostorage and allografting is a valuable technique that applies even to prepubertal girls; however, some patients cannot benefit from it due to the high risk of reintroducing cancer cells during allograft in cases of ovary-metastasizing neoplasias, such as leukemias or NH lymphomas.

Antiviral, virucidal and antioxidant properties of Artemisia annua against SARS-CoV-2.

Natural products are a rich source of bioactive molecules that have potential pharmacotherapeutic applications. In this study, we focused on Artemisia annua (A. annua) and its enriched extracts which were biologically evaluated in vitro as virucidal, antiviral, and antioxidant agents, with a potential application against the COVID-19 infection.

The HERA (Hyper-response Risk Assessment) Delphi consensus for the management of hyper-responders in in vitro fertilization.

Purpose: To provide agreed-upon guidelines on the management of a hyper-responsive patient undergoing ovarian stimulation (OS) METHODS: A literature search was performed regarding the management of hyper-response to OS for assisted reproductive technology. A scientific committee consisting of 4 experts discussed, amended, and selected the final statements. A priori, it was decided that consensus would be reached when ≥66% of the participants agreed, and ≤3 rounds would be used to obtain this consensus.

Cryostorage management of reproductive cells and tissues in ART: status, needs, opportunities and potential new challenges.

Among the wide range of procedures performed by clinical embryologists, the cryopreservation of reproductive cells and tissues represents a fundamental task in the daily routine. Indeed, cryopreservation procedures can be considered a subspecialty of medically assisted reproductive technology (ART), having the same relevance as sperm injection or embryo biopsy for preimplantation genetic testing. However, although a great deal of care has been devoted to optimizing cryopreservation protocols, the same energy has only recently been spent on developing and implementing strategies for the safe and reliable storage and transport of reproductive specimens.
