Neonatal uterine bleeding (NUB) occurs in approximately 5% of newborns and is generally considered to be of little clinical significance. However, the real clinical importance of this condition and its long-term implications remain to be de…

Accumulating evidence indicates that adolescent endometriosis is common and often severe. Here we explore the possibility that seeding of naive endometrial progenitor cells into the pelvic cavity early in life, that is, at the time of neona…

INTRODUCTION: Treatment of ovarian endometriomas is commonly achieved through laparoscopic surgery and this can be effective in eliminating the disease, although a majority of recent trials documented an adverse effect of surgery on ovarian…

OBJECTIVE: To evaluate existing evidence of a possible association in women with endometriosis between controlled ovarian hyperstimulation plus embryo transfer (COH-ET) and the occurrence of spontaneous hemoperitoneum in pregnancy (SHiP). …

The life-cycle approach to endometriosis highlighted unexpected features of the condition; the same approach was therefore applied to gain insight into the clinical features of adenomyosis and to draw a comparison with endometriosis. This i…

Past studies have clearly shown the existence of a spectrum of endometrial progesterone responses in neonatal endometrium, varying from proliferation to full decidualization with menstrual-like shedding. The bleedings represent, similar to …

reconstruction of endometriosis according to different sources

Background Different fetomaternal conditions may influence the risk of endometriosis during adolescence and in adult life; here we focus on the hormonal maturation of the fetal endometrium in the final stages of pregnancy and on the theory …

Three main theories have been put forward to explain the pathogenesis of endometriosis, that of a retrograde menstrual transplantation, that of an induction of endometrial cells, and that of an in situ development. These hypotheses belong t…

BACKGROUND: Scientific data on the phenomenon of uterine bleeding in the neonate (NUB) began to appear over a century ago when angiogenesis and petechial haemorrhages in the endometrium of newborn female infants, as well as fluid blood with…

OBJECTIVE: Evaluate if different bleeding patterns associated with the use of the levonorgestrel intrauterine system (LNG-IUS) are associated with different uterine and endometrial vascularization patterns, as evidenced by ultrasound power …

BACKGROUND: Aim of this prospective, case-control study was to evaluate uterine arteries' blood flow before and after laparoscopic surgery in patients with ovarian endometriosis and its possible correlation with infertility. METHODS: We pr…

The pathogenesis of early-onset endometriosis has recently been revisited, sparked by the discovery of endometrial stem/progenitor cells and their possible role in endometriosis, and because maternal pregnancy hormone withdrawal following d…
