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 …

Study questionDo low levels of anti-Müllerian hormone (AMH) or antral follicle count (AFC) properly predict miscarriage in young women conceiving with ART?Summary answerLow ovarian reserve, as indicated by AMH or AFC, is not associated with…

STUDY QUESTION: Is it possible to reduce the cost of GnRH agonist treatment for endometriosis by using non-standard dosing regimens? SUMMARY ANSWER: An extended-interval dosing regimen of a 3.75 mg depot formulation of triptorelin injected…

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 …

According to consistent epidemiological data, the slope of the incidence curve of endometriosis rises rapidly and sharply around the age of 25 years. The delay in diagnosis is generally reported to be between 5 and 8 years in adult women, b…

The potential for repeated ovulation and menstruation is thought to have provided a Darwinian advantage during the Palaeolithic. Reproductive conditions remained relatively stable until the pre-industrial era, characterized by late menarche…

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

Study questionDo small and asymptomatic intramural and subserosal uterine fibroids affect female fertility?Summary answerSmall and asymptomatic fibroids that do not encroach the endometrial cavity appear to not markedly affect female fertil…

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…

AGD is the distance measured from the anus to the genital tubercle. Recent evidence suggests that a shorter AGD, a sensitive biomarker of the prenatal hormonal environment, could be associated with higher endometriosis risk. However, studie…

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…

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…

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 Does endometriosis affect the expression of the aromatase gene CYP19A1 in the cumulus oophorous (COCs) and mural lutein-granulosa cells (GCs) influencing ART procedures? Summary answer Endometriosis does not impair C…

Abstract Study question We aimed to verify whether endometriosis patients who succeeded in achieving a live birth through IVF were epigenetically younger than those who did not. Summary answer Applying peripheral blood epigenetic clock, end…

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…

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 …

BACKGROUND: The epidemiology of adenomyosis has been traditionally based on patients undergoing hysterectomy for gynecological indications, while its prevalence among hysterectomies performed for obstetric complications is unknown. The aim …

Deep dyspareunia affects almost half of the women with endometriosis and is associated with vaginal endometriotic lesions. Our pilot study's objective is to assess the feasibility and effectiveness of CO2-laser ablation under colposcopic gu…

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…
