Abstract Study question Does insulin resistance affect the immune-inflammatory status in infertile women with adenomyosis? Summary answer Insulin resistance worsens endometrial inflammation, disrupting immune cell recruitment and stromal pr…

Endometriosis is defined as the presence of endometrial glands or stroma outside the uterus, commonly diagnosed in women of childbearing age frequently with subfertility. Endometriosis is associated with the presence of uterine fibroids, wh…

STUDY QUESTION: Does age affect endometrial gene expression? SUMMARY ANSWER: Using unsupervised artificial intelligence methods, we report for the first time that endometrial gene expression changes from 35 years of age in women. WHAT IS KN…

Endometriosis is a common problem affecting 5-10% of women of childbearing age. It is a condition with unknown pathology, leaving us with several theories. However, about half of women with endometriosis complain of difficulty conceiving. T…

Endometriosis is a chronic disease of the female reproductive system, which is characterised by the presence of endometrial tissue outside the uterus especially in the pelvic cavity that includes ovaries, fallopian tubes and it may occur ex…

Several studies have suggested a possible etiological association between ovarian endometriosis and ovarian cancer. Evidence has shown that KIF20A overexpression might confer a malignant phenotype to ovarian tumors by promoting proliferatio…

BACKGROUND: There is a need for a reliable marker of endometriosis, especially in early stages of peritoneal disease during which imaging is not effective. The use of serum interleukin (IL)-6 as a marker is controversial. To readdress the m…

The leptin system has been implicated in reproductive function, acting at endocrine and paracrine levels. Recently, deregulation of this gene family has been linked to endometrial changes caused by endometriosis. In the present study, we co…

Chemokines are small polypeptides that attract specific leukocyte subsets by binding to cell-surface receptors. In reproductive biology, they have been implicated in ovulation, menstruation, and embryo implantation, and pathological process…

Several analyses in our infertility (IVF) and oocyte donation programs were carried out to gain clinical knowledge of the factors involved in the etiology of endometriosis-associated infertility. We first compared the IVF outcomes in women …

The use of in-vitro fertilization (IVF) as a therapeutic tool in patients with endometriosis has provided information about the disease and, in particular, aspects of the reproductive process in humans, particularly folliculogenesis, fertil…

Several retrospective analyses of IVF and oocyte donation programmes, performed to gain clinical knowledge of the factors implicated in the aetiology of endometriosis-associated infertility, have demonstrated that the quality of the embryo …

Chemokines are a new family of cytokines specialised in attracting leukocytes, acting in physiological conditions and in pathological processes. A wide variety of cell types in response to exogenous irritants or endogenous mediators of the …

OBJECTIVE: To assess the endocrine milieu in follicles of stimulated cycles comparing women with and without endometriosis. Steroids were measured in follicular fluid (FF) and in in vitro culture of granulosa-luteal cells, and this status w…

To assess the impact of endometriosis on intracytoplasmic sperm injection (ICSI) outcome, we have retrospectively evaluated 980 ICSI cycles, comparing the results of women with and without endometriosis. A total of 101 cycles was identified…
