OBJECTIVE: To investigate the effect of antiangiogenic treatment on experimental endometriotic lesion nerve fibers. DESIGN: Heterologous mouse model of endometriosis. SETTING: University Institute IVI, University Hospital La Fe. ANIMAL(S…

Invasion of the trophoblast into the maternal decidua is regulated by both the trophoectoderm and the endometrial stroma, and entails the action of tissue remodeling enzymes. Trophoblast invasion requires the action of metalloproteinases (M…

Decidualization is a morphological and biochemical transformation of endometrial stromal fibroblast into differentiated decidual cells, which is critical for embryo implantation and pregnancy establishment. The complex regulatory networks h…

CONTEXT: A high chromosomal abnormalities rate has been observed in human embryos derived from in vitro fertilization (IVF) treatments. The real incidence in natural cycles has been poorly studied, so whether this frequency may be induced b…

To assess the literature on preclinical and clinical efficacy and safety data of pharmacologic groups proposed in the treatment of endometriosis, we performed a systematic review of publications from March 2002 to January 2012 via PubMed se…

OBJECTIVE: To evaluate the effect of adenomyosis on endometrial gene expression and its correlation with clinical outcome. DESIGN: Transcriptomic analysis of the endometrium of women with adenomyosis during the window of implantation. Retr…

This chapter addresses the controversies surrounding the impact and surgical management of hydrosalpinges and uterine leiomyoma on in vitro fertilization (IVF) cycle outcome. Evidence accumulated over the last 15 years suggests that either …

OBJECTIVE: To report the use of cumulative live-birth rates (CLBRs) per ovarian stimulation cycle to measure the success of IVF is proving to be the most accurate method for advising couples who failed to conceive, although the accuracy yie…

Implantation of a retrogradely shed endometrium during menstruation requires an adequate blood supply, which allows the growth of endometriotic lesions. This suggests that the development of endometriosis can be impaired by inhibiting angio…

OBJECTIVE: To assess whether dopamine receptor 2 agonists reduced the size of peritoneal lesions in women with endometriosis and elucidate whether affectation of vascular endothelial growth factor (VEGF)/VEGF receptor 2 (VEGFR2)-dependent a…

During reproductive life, the human endometrium undergoes around 480 cycles of growth, breakdown and regeneration should pregnancy not be achieved. This outstanding regenerative capacity is the basis for women's cycling and its dysfunction …

Previous studies in an experimental mouse model of endometriosis have shown that the dopamine agonist (DA) cabergoline (Cb2) reduces angiogenesis and endometriotic lesions, hypothetically binding to the dopamine receptor type-2 (DRD2). To d…

PURPOSE: To catalogue Gene Ontology terms in the sperm of infertile human males vs. donors of proven fertility by analyzing five samples from each of the two groups (five aliquots from fresh sperm and five post-swim-up). METHODS: Microarra…

Introduction: Endometriosis, defined as the growth of endometrial tissue outside \nthe uterine cavity is a common gynaecological disorder affecting 10-15% \nof women in their reproductive years. It is a major clinical problem causing in- \n…

Several drugs, shown to be safe for other uses, have proven to be highly effective adjuncts for ovarian stimulation. The authors evaluate these "orphan" indications and make recommendations so that more patients will benefit from their use.

BACKGROUND: Implantation of a retrogradely-shed endometrium during menstruation requires an adequate blood supply. The endometrium has angiogenic potential, and endometriotic lesions grow in areas with a rich vascularization, suggesting tha…
