BACKGROUND: Endometriosis is sustained by ectopic endometrial implants that remain proliferative and vascularized, making endocrine modulation a cornerstone of therapy. Estetrol (E4) an endogenous estrogen produced during pregnancy, with se…

Adenomyosis (ADM) is a multifaceted uterine pathology characterized by the ectopic infiltration of endometrial tissue into the myometrium, afflicting approximately 20% of women in the reproductive age group seeking gynecological care. This …

UNLABELLED: Endometriosis is a chronic disease characterized by the growth of the endometrium outside the uterine cavity. In response to estradiol, this tissue begins to proliferate and grow, forming lesions and nodules, which can invade th…

Estetrol (E4), a natural estrogen produced by the human fetal liver, is actively studied for menopause and breast cancer treatment. It has low side effects and preferential estrogen receptor alpha (ERα) affinity. There are no data about its…

OBJECTIVE: To evaluate deep nodular endometriotic lesions induced in baboons over 12 months and analyze collective cell migration and nerve fiber density. DESIGN: Morphologic and immunohistochemical analysis of endometriotic lesions induce…

OBJECTIVE: To determine the implications of collective cell migration in the invasion phenomenon observed in deep endometriotic lesions induced in a baboon model. DESIGN: Study of morphology and collective cell migration markers in invasiv…
