Background: Demand for elective oocyte cryopreservation (OC) among healthy women delaying childbearing is rising worldwide. Yet, clinicians and patients often rely on limited or indirect evidence to predict age-specific mature oocyte yield.…

Endometriosis is a chronic gynecological disorder characterized by ectopic endometrial-like tissue, leading to pain, dysmenorrhea, and infertility. This review explores classification systems, the mechanisms of endometriosis-related inferti…

OBJECTIVE: To assess the adequate ovarian follicular development and oocyte recovery between ovarian potential (antral follicle count [AFC]) before the start of ovarian stimulation (OS) and oocyte quantity and quality at oocyte retrieval. A…

Indicators of male fertility are in decline globally, but the underlying causes, including the role of environmental exposures, are unclear. This study aimed to examine organic chemical pollutants in seminal plasma, including both known pri…

BACKGROUND: Currently, there is no consensus on the optimal management of women with low prognosis in ART. In this Delphi consensus, a panel of international experts provided real-world clinical perspectives on a series of literature-suppor…

IntroductionThe aim of this study was to estimate the time to pregnancy and live birth and evaluate the effect of weight regain in women with a history of bariatric surgery (BS) who underwent in vitro fertilization (IVF) treatments.MethodsT…

PurposeTo compare the expression profile of extracellular vesicle microRNAs (EV-miRNAs) derived from follicular fluid after a trigger with recombinant human chorionic gonadotropin (r-hCG) or with a gonadotropin-releasing hormone GnRH agonis…

Key messageMenstruation of adolescent girls might be influenced by Covid-19 mRNA vaccine, however, the ovarian reserve estimated by AMH is not compromised.BackgroundRecent studies have suggested that the acute respiratory syndrome coronavir…

RESEARCH QUESTION: What is the outcome of fertility-preservation treatments in women with endometrioma, especially those with endometrioma larger than 4 cm? DESIGN: Retrospective cohort study. Women with definitive diagnosis of ovarian end…

ObjectiveTo study the effect of patients' immunization after coronavirus disease 2019 (COVID-19) infection or messenger ribonucleic acid (mRNA) severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine on frozen-thawed embryo tra…

ObjectiveNowadays, different modes and timing of GnRH-agonist combined with hCG trigger, for final follicular maturation, have been described. While LH + FSH are the naturally occurring final follicular maturation trigger, hCG is commonly u…

ObjectivesTo evaluates the effect of different modes of final follicular maturation triggering on the degree of apoptosis of granulosa cells (GCs) and the potential effect on progesterone secretion.MethodsThirty patients undergoing controll…

Hysterosalpingo-foam sonography (HyFoSy) is considered an acceptable alternative for hysterosalpingography (HSG). By combining HyFoSy with two and three-dimensional (2D and 3D) ultrasound and hysterosonography, a complete fertility work-up …

To assess the association between cesarean delivery and ovarian reserve, as compared to vaginal delivery. A prospective case control study conducted at a single tertiary medical center between June 2018 and June 2019. Study population inclu…

The prolonged lockdown of health services providing high-complexity fertility treatments -as currently recommended by many reproductive medicine entities- is detrimental for society as a whole, and infertility patients in particular. Global…

PurposeTo assess whether machine learning methods provide advantage over classic statistical modeling for the prediction of IVF outcomes.MethodsThe study population consisted of 136 women undergoing a fresh IVF cycle from January 2014 to Au…

BackgroundThe presence of submucous fibroids strongly impacts on IVF results, therefore, these patients should be considered for surgical or medical treatment. The aim of this study was to assess the role of Ulipristal acetate (UPA), a sele…

PurposePrimary ovarian insufficiency (POI) represents ovarian dysfunction related to very early aging of the ovaries. While the cause of POI in a majority of clinical cases remains undefined, autoimmunity is responsible for approximately 4-…

BackgroudIn order to maximize In vitro fertilization (IVF) success rates in advanced- age patients, it has been suggested to favor the use of intracytoplasmic sperm injection (ICSI) over conventional insemination (CI), with the notion that …

Endometriosis is an estrogen-dependent chronic inflammatory condition that affects women in their reproductive period causing infertility and pelvic pain. The disease, especially at the ovarian site has been shown to have a detrimental impa…

Mammalian reproduction is one of the most complex and fascinating biological phenomenon, which aims to transfer maternal and paternal genetic material to the next generation. At the end of oogenesis and spermatogenesis, both haploid gametes…

PurposeSeveral replacement protocols for frozen-thawed ET (FET) exist, with no advantage of one protocol over the others. In the present study, we aim to evaluate the outcome of natural cycle FET with modified luteal support.MethodsAll cons…

Study objectiveTo assess the reproductive outcome (spontaneous and assisted conception rates) in women who underwent laparoscopic resection of bladder endometriosis.DesignThis was a retrospective, observational study analyzing prospectively…

BACKGROUND: Various inflammatory cytokines have been implicated in the pathophysiology of severe ovarian hyperstimulation syndrome, as well as, various pregnancy complications, including preterm labor, pregnancy induced hypertension/preecla…

BackgroundThe aim of the present study was to compare the quality of embryos derived from sibling oocytes by in vitro fertilization (IVF) or ICSI.MethodsConsecutive patients with a less than 40% fertilization rate in a previous standard IVF…
