Defining the "normal uterus" by ultrasound measurement of uterine lengths, thicknesses, and angles in a population of nulliparous women: the Normal UteRus asSEssment study.

Objective: The existing classifications of congenital uterine anomalies are inconsistent and subject to criticism for various reasons. Noteworthy, there is still no universally accepted definition of normal uterus (NU) based on ultrasound measurements, making it difficult to objectively distinguish the uterine anatomical variants within the population. The purpose of the Normal UteRus asSEssment study was to define the exact three-dimensional (3D) ultrasound measurements of an NU, in terms of uterine lengths, thicknesses, and angles.

Stepwise approach of hysteroscopic cytoreductive surgery for adenomyosis in patients with recurrent implantation failure.

Objective: To study the value of hysteroscopic cytoreductive surgery for adenomyotic lesions to improve reproductive outcomes. We describe a feasible and novel minimal invasive stepwise approach, which did not result in postoperative adhesion formation and restored favorable reproductive outcomes.

Design: Video article.

Adenomyosis and Infertility: A Literature Review.

: Adenomyosis (the presence of ectopic endometrial glands and stroma below the endometrial-myometrial junction) is a benign condition which is increasingly diagnosed in younger women suffering from infertility. The aim of this narrative review was to study the pathophysiology and prevalence of adenomyosis, the mechanisms causing infertility, treatment options, and reproductive outcomes in infertile women suffering from adenomyosis. : A literature search for suitable articles published in the English language was performed using PubMed from January 1970 to July 2022.

The 10 "Cardinal Sins" in the Clinical Diagnosis and Treatment of Endometriosis: A Bayesian Approach.

Evidence-based data for endometriosis management are limited. Experiments are excluded without adequate animal models. Data are limited to symptomatic women and occasional observations.

Elective single versus double blastocyst-stage embryo transfer in women aged 36 years or older: a retrospective cohort study.

We evaluated if elective single-blastocyst transfer (eSBT) could be adopted in women aged 36 or older. In this retrospective cohort, women aged ≥36 years received IVF ovarian stimulation cycles and had ≥ two blastocysts. A total of 240 women underwent eSBT and 189 double-blastocyst transfer (DBT) in the first transfer cycle.

ESHRE certification of ART centres for good laboratory and clinical practice.

Study Question: Three years after the start of the ESHRE ART Centre Certification (ARTCC) programme, what is the current state of the system, in terms of the interest expressed in it and experiences during the assessment of ART services?

Summary Answer: As of 1 December 2021, 25 European ART centres have been involved in the various stages of certification and the most common recommendations from inspectors were the need for documented training, verification of competencies for all staff members, verification of laboratory and clinical performance indicators, implementation of a quality management system and avoidance of overusing ICSI and add-ons.

What Is Known Already: European Union (EU) legislation has included ART activities in the EU Tissue and Cells Directives (EUTCDs). Following inspections by national EUTCD authorities, many details regarding documentation, laboratory environment, handling of reproductive cells and tissues, traceability, coding and patient testing have become standardized.

Reproductive outcomes with donor sperm in couples with severe male-factor infertility after intracytoplasmic sperm injection failures.

Purpose: To evaluate reproductive outcomes of artificial insemination and IVF with donor sperm (AID or IVF-D) for male-factor couples with a history of unsuccessful ICSI attempt.

Methods: This retrospective cohort includes couples with severe male-factor infertility who failed ICSI treatment, and subsequently underwent semen donation treatment. We report the following outcomes: (1) live birth rates in AID and IVF-D treatment for couples with severe male infertility factors and prior ICSI failures; (2) paternal impact on embryo development of the same oocyte cohort; (3) prognostic factors in obtaining a live birth with donor semen.

Current knowledge about the management of congenital cervical malformations: a literature review.

The prevalence of congenital cervical agenesis or dysgenesis ranges from 1/80,000 to 1/100,000, and in about 50% of these cases it coexists with congenital vaginal agenesis. This narrative review summarizes the contemporary knowledge in the field of conservative surgical restoration of the reproductive tract. The management of congenital cervical malformations aims to [1] provide relief from the obstructive symptoms, [2] establish normal sexual function, and [3] preserve the uterus for future fertility.

Exploring the challenges for a new classification of adenomyosis.

The availability of non-invasive diagnostic tests is an important factor in the renewed interest in adenomyosis, as the disease can now be more accurately mapped in the uterus without a need for hysterectomy. An agreed system for classifying and reporting the condition will enhance our understanding of the disease and is envisaged to enable comparison of research studies and treatment outcomes. In this review, we assess previous and more recent attempts at producing a taxonomy, especially in view of the latest proposal for subdivision of adenomyosis into an internal and an external variant.

Diagnosing adenomyosis: an integrated clinical and imaging approach.

Background: Adenomyosis is a benign uterine disorder where endometrial glands and stroma are pathologically demonstrated within the uterine myometrium. The pathogenesis involves sex steroid hormone abnormalities, inflammation, fibrosis and neuroangiogenesis, even though the proposed mechanisms are not fully understood. For many years, adenomyosis has been considered a histopathological diagnosis made after hysterectomy, classically performed in perimenopausal women with abnormal uterine bleeding (AUB) or pelvic pain.

Symptoms and classification of uterine adenomyosis, including the place of hysteroscopy in diagnosis.

Where histology used the presence of glands and/or stroma in the myometrium as pathognomonic for adenomyosis, imaging uses the appearance of the myometrium, the presence of striations, related to the presence of endometrial tissue within the myometrium, the presence of intramyometrial cystic structures and the size and asymmetry of the uterus to identify adenomyosis. Preliminary reports show a good correlation between the features detected by imaging and the histological findings. Symptoms associated with adenomyosis are abnormal uterine bleeding, pelvic pain (dysmenorrhea, chronic pelvic pain, dyspareunia), and impaired reproduction.

Progress in the diagnosis and management of adolescent endometriosis: an opinion.

Increasing evidence indicates that early onset endometriosis (EOE), starting around menarche or early adolescence, may have an origin different from the adult variant, originating from neonatal uterine bleeding (NUB). This implies seeding of naïve endometrial progenitor cells into the pelvic cavity with NUB; these can then activate around thelarche. It has its own pathophysiology, symptomatology and risk factors, warranting critical management re-evaluation.

Pathogenesis of deep endometriosis.

The pathophysiology of (deep) endometriosis is still unclear. As originally suggested by Cullen, change the definition "deeper than 5 mm" to "adenomyosis externa." With the discovery of the old European literature on uterine bleeding in 5%-10% of the neonates and histologic evidence that the bleeding represents decidual shedding, it is postulated/hypothesized that endometrial stem/progenitor cells, implanted in the pelvic cavity after birth, may be at the origin of adolescent and even the occasionally premenarcheal pelvic endometriosis.

The management of polyps in female reproductive organs.

Polyps of the lower reproductive tract are found in 7.8-50% of women. It has been hypothesized that cytogenetic modifications on chromosomes 6, 7 and 12 as well as epigenetic factors involving enzyme and metabolic activities may cause polyps to develop.

Transvaginal laparoscopy: A minimally invasive approach to obtain brush cytology of the Fallopian tube.

Objective: To evaluate in a prospective pilot study the feasibility of cytobrushing of the fimbrial end using a transvaginal endoscopic access.

Study Design: Prospective feasibility study. The procedure was performed in a consecutive series of 15 infertile women referred for a transvaginal laparoscopy as part of their fertility investigation.

Pharmacologic treatment of the ovarian endometrioma.

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 reserve markers. With the advancement in imaging techniques, ovarian endometriomas are increasingly diagnosed at an earlier stage when the endometrioma may be smaller, less fibrotic and more responsive to medical treatment, making an evaluation of medical options critically important.

Areas Covered: The review focuses on currently utilized pharmacologic therapies for endometrioma (oral contraceptives, the levonorgestrel-releasing IUS, the hormone-releasing subdermal implant, Implanon); experimental and future treatments are also mentioned (GnRH antagonists, progesterone receptor modulators, antioestrogens, newer subdermal implants and intracystic administration of pharmacologic agents).

Hysteroscopy in recurrent in-vitro fertilisation failure (TROPHY): a multicentre, randomised controlled trial.

Background: The success rate of in-vitro fertilisation (IVF) remains low and many women undergo multiple treatment cycles. A previous meta-analysis suggested hysteroscopy could improve outcomes in women who have had recurrent implantation failure; however, studies were of poor quality and a definitive randomised trial was needed. In the TROPHY trial we aimed to assess whether hysteroscopy improves the livebirth rate following IVF treatment in women with recurrent failure of implantation.

A new approach to the management of ovarian endometrioma to prevent tissue damage and recurrence.

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 capable of preserving future fertility, the molecular pathology of ovarian endometrioma is reviewed and mechanisms by which the endometrioma progressively affects the ovary during reproductive life are summarized. The scope of new therapeutic modalities includes restoring the progesterone receptor ratio using progestin or progesterone receptor modulators and decreasing local oestrogen production through an aromatase inhibitor.

Origins and Progression of Adolescent Endometriosis.

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 neonatal uterine bleeding or soon after the menarche, results in more florid and progressive disease, characterized by highly angiogenic implants, recurrent ectopic bleeding, and endometrioma formation. We discuss the potential intergenerational risk factors associated with early-onset endometriosis and explore the molecular drivers of disease progression.

The Thessaloniki ESHRE/ESGE consensus on diagnosis of female genital anomalies.

What is the recommended diagnostic work-up of female genital anomalies according to the European Society of Human Reproduction and Embryology (ESHRE)/European Society for Gynaecological Endoscopy (ESGE) system? The ESHRE/ESGE consensus for the diagnosis of female genital anomalies is presented. Accurate diagnosis of congenital anomalies still remains a clinical challenge due to the drawbacks of the previous classification systems and the non-systematic use of diagnostic methods with varying accuracy, with some of them quite inaccurate. Currently, a wide range of non-invasive diagnostic procedures are available, enriching the opportunity to accurately detect the anatomical status of the female genital tract, as well as a new objective and comprehensive classification system with well-described classes and sub-classes.
