Neonatal uterine bleeding (NUB) has been hypothesized as a relatively common early-life event potentially linked to the later development of endometriosis through retrograde menstruation. However, its true prevalence and biological nature r…

The link between endometriosis and other medical conditions is gaining attention. Such insights could enhance clinical approaches to manage the disease and potentially reveal new, unrecognized mechanisms of its development. The aim of this …

INTRODUCTION: Endometriosis is a common, benign, chronic inflammatory disease with multiple consequences, from chronic pain to systemic comorbidities and poor quality of life. As it usually affects people of reproductive age, one of the mos…

BACKGROUND: Pregnancy involves a fine-tuned hormonal interplay between the fetus, placenta, and mother, which shapes long-term developmental outcomes. Endometriosis has been hypothesized to originate in utero due to altered fetal exposure t…

Abstract Study question What is the prevalence of endometrial polyps in women with endometriosis and vice versa? Summary answer Available data showed that there is a bidirectional association between endometriosis and endometrial polyps, pa…

Abstract Study question Is IVF more effective than surgery for treating infertility associated to ovarian and deep endometriosis detected at ultrasound? Summary answer The live birth rate within a year from the study’s beginning was signifi…

BACKGROUND: Early reports from the beginning of this century highlighted significant ovarian damage following laparoscopic stripping of endometriomas. During the last 2 decades, the raised awareness of the possible detrimental effects of su…

Abstract Study question Does endometriosis affect the cumulative live birth rate in patients undergoing IVF compared to matched controls? Summary answer The cumulative live birth rates of patients with endometriosis are comparable to those …

Abstract Study question Do umbilical vein cord blood hormonal levels differ among pregnant women with endometriosis, polycystic ovarian syndrome (PCOS), and healthy controls delivering singleton female infants? Summary answer Umbilical cord…

RESEARCH QUESTION: What is the rate of second children among women affected from endometriosis who conceived their first child through Assisted Reproduction Technologies (ARTs)? Are there differences between endometriosis and other causes o…

(Abstracted from Reprod Biomed Online 2023;47:103414 Endometriosis is a well-established risk factor for infertility due to alterations in folliculogenesis, oocyte release from the ovaries, tubal function, and oocyte fertilization. In addit…

PURPOSE: There is several albeit not univocal evidence suggesting that ovarian reserve is not related to the chance of natural pregnancy, provided that the remnant follicular pool is sufficient to ensure regular menstrual cycles. Neverthele…

PURPOSE: A reduced oocyte competence has been claimed as one of the factors underlying infertility in women with endometriosis. This idea has justified the hypothesis that intracytoplasmic sperm injection (ICSI), rather than conventional IV…

With the introduction of vitrification and the improvement in clinical outcomes, oocyte freezing for fertility preservation is currently proposed for an increasing number of indications. In this review, we have addressed the rationale to pr…

Advanced endometriosis is associated with a reduction of IVF success. Surgical damage to the ovarian reserve following the excision of endometriomas has been claimed as a critical factor in the explanation of this detrimental effect. Howeve…

RESEARCH QUESTION: Is endometriosis detrimental to embryo implantation? DESIGN: A retrospective matched case-control study of women with a surgical or ultrasound diagnosis of endometriosis at Fondazione IRCCS Ca'Granda Ospedale Maggiore Po…

The second-to-four digit ratio (2D:4D) has been proposed as a marker of prenatal hormonal exposure. It is suggested that prenatal exposure to androgens results in a shorter 2D:4D ratio, whereas a prenatal oestrogenic environment results in …

Abstract Study question Does endometriosis affect endometrial receptivity in frozen/thawed embryo transfer (FET) cycles? Summary answer Stage III/IV endometriosis-patients undergoing ART submitted to FET cycles have implantation, pregnancy …

Abstract Study question What is the prevalence and the cause of neonatal uterine bleeding, also known as “genital crisis”? Is it associated with maternal lifestyle and obstetric history? Summary answer The prevalence of NUB has been estimat…

Abstract Study question This study investigates a possible association between the second-to-four digit ratio and endometriosis. Summary answer There is an association between a higher 2D:4D ratio and the presence of endometriosis. What is …

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…

Abstract Study question The present study was designed to better elucidate if endometriosis may affect follicologenesis and embryo development within a cycle of ovarian hyperstimulation for IVF (In Vitro Fertilization). Summary answer Endom…

Abstract Study question Can sonohysterography-detected CSD have a deleterious effect on reproductive outcomes in women with secondary infertility undergoing IVF? Summary answer A 68% prevalence of CSD has been estimated in the study populat…
