Neonatal uterine bleeding (NUB) has been carefully studied in the past through case reports, small series, clinical cohort studies, pathology investigations of fetal and neonatal. Following a historical recount, this review summarizes biolo…

Management of ovarian endometrioma is a matter of debate between those advocating early treatment and those believing that cysts less than 3 cm in diameter should not be submitted to surgery. To explore a new approach to its management capa…

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 …

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…

The fetal endometrium becomes responsive to steroid hormones around the fourth month of pregnancy starting with an oestrogenic phase, which is followed late in pregnancy by a secretory phase. Based on post-mortem studies, the endometrium at…

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…

INTRODUCTION: Several selective progesterone receptor modulators (SPRMs) show promise in several areas of medicine and this work has been summarized by us in 2008. AREAS COVERED: Since the publication of our reviews, several developments h…

A dispute has recently emerged whether early descriptions exist of the condition we name endometriosis. A first question is: 'Who identified endometriosis?' To respond, two non-complementary methods have been employed: searching for ancient…

PURPOSE OF REVIEW: We adopted a life-cycle approach to further our understanding of the natural history of the cystic forms of uterine adenomyosis first described by Cullen in 1908. SEARCH STRATEGY: Scopus and PubMed were searched for all …

There are now convincing data showing that cystectomy of the endometrioma is not only no cure of infertility, but may harm follicle reserve. The question arises why is cystectomy for an endometrioma, in contrast with other -benign cysts, a …

To improve the still fragmented understanding of endometriosis, a life cycle approach was adopted that revealed unexpected aspects of the natural history of the disease throughout a woman's life. Three age-related stages of endometriosis ar…

Endometriosis in the adolescent has, in recent years, been discovered to be a challenging problem in gynaecology. Although the pain may start at a young age, even before the onset of menstruation, the diagnosis by laparoscopy is almost alwa…

Adverse living and nutritional conditions in utero and in early infancy may influence the risk of diseases in adult life, because fetal growth seems determined by interactions between the environment and the fetal genome and these interacti…

We elaborate on a new theory to explain pelvic endometriosis, including endometriosis in premenarcheal girls, based on the finding that the neonatal endometrium can display secretory activity immediately after birth and, in some cases, chan…
