PurposeTo evaluate the association between serum progesterone (P) at the day of ovulation trigger and neonatal birthweight in singletons born after frozen-thawed embryo transfer in segmented ART cycles.MethodsA retrospective multicenter coh…

BackgroundIn women scheduled for cancer treatment, oocytes cryopreservation is a well-established procedure. Random start protocols have been a substantial improvement in this setting, allowing to prevent delay in the initiation of cancer t…

Endometriosis is an estrogen-dependent chronic inflammatory disease characterized by the presence of endometrial glands and stroma associated with fibrosis outside the uterine cavity [...].

Endometriosis was claimed to negatively affect the intrafollicular environment, hindering oocyte competence. Previous studies evaluated expression levels of cytochrome P450 aromatase (CYP19A) in granulosa and cumulus oophorus cells collecte…

Endometriosis is a complex and chronic disease, whose multifactorial nature has encouraged a deep investigation on the role of lifestyle factors. A strong association between alcohol intake and endometriosis risk has already been shown. We …

Decidualization is the process of endometrial change in pregnancy, a phenomenon that can involve also ovarian endometriomas. However, the frequency of this event remains unknown. In addition, there is no evidence on the decidualization of d…

There is growing interest on the potential clinical relevance of the endometrial microbiome. However, insufficient attention has been given to the methodology of sampling. To minimize contamination, we advocate the use of the double-lumen c…

PURPOSE: To evaluate obstetric outcome in women with endometriosis who conceive naturally and receive standard obstetric care in Italy. METHODS: Cases were consecutive women with endometriosis managed in eleven Italian referral centers. Co…

Conventional IVF (c-IVF) is one of the most practiced assisted reproductive technology (ART) approaches used worldwide. However, in the last years, the number of c-IVF procedures has dropped dramatically in favor of intracytoplasmic sperm i…

ObjectiveTo evaluate whether telomere length (TL), mitochondrial-DNA (mt-DNA) or epigenetic age estimators based on DNA methylation (DNAm) pattern could be considered reliable predictors of in-vitro-fertilization (IVF) success in terms of l…

The frozen embryo transfer (FET) technique has been progressively used more worldwide due to improved culture conditions, as well as enhanced survival rates after vitrification. However, little is known about the effect of the post-thaw bla…

The management of endometriosis-related infertility is still a challenging issue. Women can be managed with either surgery or in vitro fertilization (IVF). The decision is tailored to the patients considering pros and cons of both approache…

RESEARCH QUESTION: The detrimental effects of endometriosis on IVF success are well known, but the underlying mechanisms are still uncertain. The objective of this study was to investigate the possible detrimental effects of the disease on …

Women undergoing in vitro fertilization (IVF) are emotionally challenged. Anxiety, depression, and sleep disturbances are common complaints. The impact of these symptoms on IVF outcome is however debated. In this study, we aimed at investig…

Abstract Decidualization is the process of endometrial change in pregnancy, a phenomenon that can involve also ovarian endometriomas. However, the frequency of this event remains unknown. In addition, there is no evidence on the decidualiza…

Management of women with endometriosis in general is complex. It requires a multidisciplinary and tailored approach. The time of in-vitro fertilization (IVF) may be particularly complicated because women with the disease face peculiar addit…

Research questionWhat are the associations between endometriosis, pelvic pain symptoms, fatigue and sleep? Psychological health and quality of life in endometriosis patients with good versus bad quality of sleep were also examined.DesignThi…

IntroductionRecent data suggest a higher clinical pregnancy rate performing assisted hatching (AH) on previously cryopreserved embryos but fail to demonstrate significant effects on live birth rate. However, current evidence is based on stu…

In recent decades, increasing attention has been paid to the influence of diet on reproductive health. Carbohydrates in diet affect glucose metabolism and multiple evidences showed the key role of insulin sensitivity in regulating female fe…

ObjectiveTo estimate the frequency of spontaneous hemoperitoneum in pregnancy (SHiP) in women with endometriosis achieving pregnancy with in vitro fertilization (IVF).DesignRetrospective case series.SettingReferral academic assisted reprodu…

Several pathogenetic mechanisms have been postulated to explain the association between endometriosis and subfertility. However, to date, definitive conclusions cannot be drawn. In this study, we hypothesized that the reduced exploitation o…

A consistent body of in vitro evidence supports a detrimental effect of endometriosis on ovarian steroidogenesis, in particular the synthesis of estrogens. However, clinical evidence is scanty and methodologically weak. This study aimed at …

ObjectiveWe investigated whether lifestyle affects assisted reproduction technology (ART) outcomes.DesignCohort study.SettingItalian fertility unit.ParticipantsFrom September 2014 to December 2016, women from couples presenting for evaluati…
