To confirm the origin of cancer found in both the endometrium and the myometrium is difficult. Cancer may spread from the endometrium into adenomyotic foci or vice versa. Also, premalignant changes may arise at either or both sites.

Spontaneous Hemoperitoneum in Pregnancy (SHiP), an unprovoked (nontraumatic) intraperitoneal bleeding in pregnancy (up to 42days postpartum), is associated with serious adverse pregnancy outcomes. To evaluate the clinical consequences of SHiP and its association with endometriosis, a systematic review was conducted according to the PRISMA guidelines. PubMed, Embase.

Background: Spontaneous hemoperitoneum in pregnancy (SHiP) is a rare, life-threatening event, particularly relevant to women with endometriosis or deciduosis.

Methods: To determine the type of lesions leading to SHiP, a literature search was conducted among all published SHiP cases. From a total of 1,339 publications, information on pathological findings at the bleeding site with histological data was found in 24 case reports (16 pregnant, 8 postpartum).

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).

Design: Comprehensive review.

Setting: Not applicable.

Aim: The rate of oocyte decline follows a biphasic pattern, characterized by acceleration between 32 and 38 years old. Ovarian reserve is also affected by external factors, including ovarian disease and iatrogenic damage. The aim of this study was to histologically evaluate the impact of ovarian endometriomas, laparoscopic cystectomy, and age on follicle reserve in healthy ovarian tissues and in surgically resected cyst walls.

Spontaneous hemoperitoneum in pregnancy (SHiP) is a rare but dramatic cause of perinatal mortality and morbidity. Emerging evidence suggests that pelvic endometriosis may play an important role in the pathogenesis of SHiP.

Menstruation is widely viewed as serving no purpose other than to reinitiate the endometrial cycle in the absence of pregnancy. Yet, it is striking that cyclic endometrial decidualization followed by menstrual shedding is confined to the few species, including human beings, where placenta formation entails deep trophoblast invasion of maternal tissues and its vasculature. Both menstruation and pregnancy are inflammatory conditions that cause a degree of physiological ischemia-reperfusion tissue injury, albeit much more so in pregnancy.

The fetomaternal interface, consisting of the maternal decidua and the invading fetal trophoblast, critically regulates placental function and the growth and development of the conceptus. In its broadest sense, decidualization could be viewed as the postovulatory process of endometrial remodeling in preparation for pregnancy, which includes secretory transformation of the uterine glands, influx of specialized uterine natural killer cells, and vascular remodeling. A more restricted definition of the decidual process denotes the morphological and biochemical reprogramming of the endometrial stromal compartment.

Background: We postulated that impaired endometrial differentiation in women with pelvic endometriosis predisposes for pre-eclampsia.

Methods: A retrospective case-control study set at the University of Ghent IVF centre. The incidence of pre-eclampsia and pregnancy-induced hypertension (PIH) following the clinical and/or laparoscopic diagnosis of endometriosis-associated infertility (case group; n = 245 pregnancies) was compared with the incidence of these obstetric complications in pregnancies following treatment for male-factor infertility (control group; n = 274 pregnancies).

Deep placentation in the human requires physiologic transformation of the spiral arteries into uteroplacental vessels. This process involves the inner myometrial segment (junctional zone) of the spiral arteries and is effected by trophoblast invasion of the vessel wall, resulting in complete loss of the arterial structure and deposition of fibrinoid and fibrous tissues. Absent or inadequate physiologic changes in the junctional zone spiral arteries limits placental blood flow in pregnancies complicated by preeclampsia and fetal growth restriction.
