Purpose: The aim of this study was to determine if pregnancy-associated plasma protein-A (PAPP-A), typically measured in maternal serum and a potential predictor of adverse maternal and fetal outcomes such as spontaneous miscarriage, pre-eclampsia, and stillbirth, is expressed in blastocoel fluid-conditioned media (BFCM) at the embryonic blastocyst stage.

Design: This is an in vitro study.

Methods: BFCM samples from trophectoderm-tested euploid blastocysts (n = 80) from in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) patients were analyzed for PAPP-A mRNA.

Objective(s): To determine if hysteroscopic removal of endometrial polyps, specifically via morcellation of polyps, affects implantation rate (IR), clinical pregnancy rate (CPR), spontaneous abortion (SAB) rate, and live birth rate (LBR) in first frozen embryo transfer (FET) cycles.

Study Design: Retrospective chart review, with data abstracted from the charts of all first autologous oocyte frozen embryo transfer (FET) cases (n = 135) at a single fertility center from January 2018 through June 2020. Subjects were grouped into (A) hysteroscopic polypectomy prior to first FET (n = 25) or (B) no hysteroscopic polypectomy prior to first FET (n = 110).

Despite an estimated prevalence of 11% in women and plausible historical descriptions dating back to the 17th century, the etiology of endometriosis remains poorly understood. Classical theories of the histological origins of endometriosis are reviewed below. Clinical presentations are variable, and signs and symptoms do not correlate well with the extent of disease.

Introduction: Fetal microchimerism has been implicated in the etiology of autoimmune diseases. This study was done to test the hypothesis that male fetal microchimerism is present in eutopic and ectopic endometrium (EM) obtained from women with endometriosis but not in eutopic EM from women without endometriosis.

Methods: A total of 31 patients were selected, including women with endometriosis (paired eutopic and ectopic EM; n = 19) and women without endometriosis (eutopic EM; n = 12).

The da Vinci(®) robotic surgical system has been used more often in recent years for tubal anastomosis (TA) and has been reported to have an increased operative time. A one-stitch technique has been used for the reanastomosis step in laparoscopic TA. To date, publications on robotically-assisted TA (RATA) describe an anastomotic step with multiple (usually four) sutures placed.

Endometriosis is a chronic disease in which epithelial and stromal cells that resemble the eutopic endometrium are found in ectopic lesions. In order to examine how microenvironmental factors such as extracellular matrix and macrophages influence disease progression, 12Z (an immortalized ectopic epithelial cell line) were cultured on tissue culture plastic (TCP) or in gels of recombinant basement membrane (rBM) or collagen I. Unlike cells in other conditions, cells in rBM formed multi-cellular structures in a 67 kDa non-integrin laminin receptor (67LR)-dependent manner.

Endometriosis affects a significant proportion of reproductive-aged women. The impact of the disease on ovarian function is an important consideration when planning treatment in women who want to retain the potential of future childbearing. This review will specifically address the association between endometriomas and diminished ovarian reserve, with a particular focus on the impact of surgical endometrioma resection on ovarian function.

The endometrium is ground zero when it comes to understanding how implantation occurs and how it might also fail, resulting in infertility or pregnancy loss. Many of the causes of diminished uterine receptivity are acquired during a woman's lifetime. Endometriosis, a major inflammatory disease affecting women, is also a leading cause of infertility and miscarriage.

Objective: To examine the impact of a recent surgery on development of endometriosis-related adhesions in a chimeric model and to determine the therapeutic efficacy of pioglitazone (PIO).

Design: Human endometrial biopsies were maintained in E(2) with or without PIO for 24 h before intraperitoneal injection into immunocompromised mice also treated with or without PIO at multiple time points after peritoneal surgery. The presence and extent of adhesions were examined in animals relative to the initial establishment of experimental endometriosis.

Objective: Many women with endometriosis experience significant delay between the onset of symptoms and definitive diagnosis. Much is published on physician awareness of endometriosis and on the experiences of women with the condition. There is a paucity of data, however, surrounding perceptions of endometriosis in the general population.

A prospective, randomized, placebo-controlled study was conducted in a baboon model to determine if a thiazolidinedione agonist of peroxisome proliferator-activated receptor-gamma, pioglitazone, can impede the development of endometriosis. Endometriosis was induced using laparoscopic, intrapelvic injection of eutopic menstrual endometrium, previously incubated with placebo or pioglitazone for 30 min, in 12 female baboons with a normal pelvis that had undergone at least one menstrual cycle since the time of captivity. At this point, the 12 baboons were randomized into two groups and treated from the day of induction.

Background: Current medical therapies for endometriosis result in delayed conception and have not been shown to provide any fertile benefit subsequent to treatment. Thiazolidinediones (TZDs) do not impede conception and have been shown to reduce endometriotic lesions in animal models; however, no studies have been performed in humans. The aim of this study was to provide preliminary data about the effectiveness of a TZD in treating endometriosis-related pain.
