Eutopic and Ectopic Endometrial Interleukin-17 and Interleukin-17 Receptor Expression at the Endometrial-Myometrial Interface in Women with Adenomyosis: Possible Pathophysiology Implications.

Adenomyosis involves the infiltration of endometrial glands and stroma deep into the uterine tissue, causing disruption to the endometrial-myometrial interface (EMI). The role of interleukin-17 (IL-17) has been extensively studied in endometriosis, but its involvement in adenomyosis remains unclear. This study aimed to investigate the expression of IL-17 in eutopic and ectopic endometrium (adenomyosis) of individuals with adenomyosis at the level of EMI.

A case study of transneovaginal oocyte retrieval after novel Lee's neovaginoplasty in Mayer-Rokitansky-Küster-Hauser syndrome.

Objective: Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a rare congenital disorder that results in vaginal agenesis. Lee's neovaginoplasty is a novel surgery for reconstructing the vagina. Transneovaginal oocyte retrieval completely changes the scope of fertility for patients with MRKH syndrome who have undergone neovaginal reconstruction.

Ovarian stimulation response and fertility outcomes in patients with breast cancer across different stages, grades, and hormone receptor status for fertility preservation.

Background: This study aimed to explore the potential impact of stage, grade, and hormone receptor profile on ovarian stimulation response and fertility preservation outcomes.

Methods: This retrospective cohort study evaluated data from breast cancer patients who underwent fertility preservation at a tertiary medical center between 2014 and 2022. The outcomes of women with low-stage cancer (stages I and II) were compared with those of women with high-stage disease (stages III and IV or lymph node metastasis).

Results: The blastocyst formation rate was significantly higher (p = 0.

LIF-STAT signaling in decidual cells: a possible role in embryo implantation and early pregnancy.

In this study, we investigate the effects of miRNA-138-5p and probable G-protein coupled receptor 124 (GPR124)-regulated inflammasome and downstream leukemia inhibitory factor (LIF)-STAT and adhesion molecule signaling in human decidual stromal cells. After informed consent was obtained from women aged 25-38 years undergoing surgical termination of the normal pregnancy and spontaneous miscarriage after 6-9 weeks of gestation, human decidual stromal cells were extracted from the decidual tissue. Extracellular vesicles (EVs) with microRNA (miRNA) between cells have been regarded as critical factors for embryo-maternal interactions on embryo implantation and programming of human pregnancy.

Successful Twin Delivery Through In Vitro Fertilization in a High-Gestation Age Kidney Transplant Recipient: A Case Report.

Background: Numerous successful pregnancy outcomes have been reported after kidney transplantation, but until now, there have been no reports of healthy twin deliveries through in vitro fertilization treatment in high-gestation aged women with a long post-transplant duration. In our report, we present a case of a high-gestation aged kidney transplant recipient who successfully delivered healthy twins with the aid of in vitro fertilization.

Case Presentation: At the age of 29, a woman with end-stage kidney disease caused by immunoglobin A nephropathy underwent kidney transplantation.

Kisspeptin Regulates Cell Invasion and Migration in Endometrial Cancer.

Kisspeptin (a product of the KISS1 gene and its receptor) plays an important role in obstetrics, gynecology, and cancer cell metastasis and behavior. In hypothalamic-pituitary-gonadal axis and placentation, Kisspeptin/Kisspeptin receptor affects hormone release and represses trophoblast invasion into maternal deciduae. Endometrial cancer is one of the common gynecological cancers and is usually accompanied by metastasis, the risk factor that causes death.

Gut Microbiome-Estrobolome Profile in Reproductive-Age Women with Endometriosis.

Microbiota is associated with our bodily functions and microenvironment. A healthy, balanced gut microbiome not only helps maintain mucosal integrity, prevents translocation of bacterial content, and contributes to immune status, but also associates with estrogen metabolism. Gut dysbiosis and estrobolome dysfunction have hence been linked to certain estrogen-dependent diseases, including endometriosis.

Priming of macrophage by glycosphingolipids from extracellular vesicles facilitates immune tolerance for embryo-maternal crosstalk.

Glycosphingolipids (GSLs) display diverse functions during embryonic development. Here, we examined the GSL profiles of extracellular vesicles (EVs) secreted from human embryonic stem cells (hESCs) and investigated their functions in priming macrophages to enhance immune tolerance of embryo implantation. When peripheral blood mononuclear cells were incubated with ESC-secreted EVs, globo-series GSLs (GHCer, SSEA3Cer, and SSEA4Cer) were transferred via EVs into monocytes/macrophages.

EGF-Enhanced GnRH-II Regulation in Decidual Stromal Cell Motility through Twist and N-Cadherin Signaling.

Crucial roles in embryo implantation and placentation in humans include the invasion of the maternal decidua by extravillous trophoblasts and the motile behavior of decidual endometrial stromal cells. The effects of the epidermal growth factor (EGF) and GnRH-II in the endometrium take part in early pregnancy. In the present study, we demonstrated the coaction of EGF- and GnRH-II-promoted motility of human decidual endometrial stromal cells, indicating the possible roles of EGF and GnRH-II in embryo implantation and early pregnancy.

A Lifelong Impact on Endometriosis: Pathophysiology and Pharmacological Treatment.

Endometriosis is a chronic inflammatory disease associated with bothersome symptoms in premenopausal women and is complicated with long-term systemic impacts in the post-menopausal stage. It is generally defined by the presence of endometrial-like tissue outside the uterine cavity, which causes menstrual disorders, chronic pelvic pain, and infertility. Endometriotic lesions can also spread and grow in extra-pelvic sites; the chronic inflammatory status can cause systemic effects, including metabolic disorder, immune dysregulation, and cardiovascular diseases.

Endothelial dysfunction in subfertile women with polycystic ovary syndrome.

Research Question: Is there an association between post-occlusive reactive hyperaemia (PORH) and ovarian stimulation in women with normoandrogenaemic polycystic ovary syndrome (PCOS)?

Design: Women eligible for IVF at an academic fertility centre were invited to join this prospective study. Microvascular endothelial function was measured as PORH by laser Doppler flowmetry (LDF) before and after ovarian stimulation. Metabolic characteristics, hormone profiles and biochemical markers were analysed.

Immune Tolerance of Embryo Implantation and Pregnancy: The Role of Human Decidual Stromal Cell- and Embryonic-Derived Extracellular Vesicles.

Embryo-endometrial communication plays a critical role in embryo implantation and the establishment of a successful pregnancy. Successful pregnancy outcomes involve maternal immune modulation during embryo implantation. The endometrium is usually primed and immunomodulated by steroid hormones and embryo signals for subsequent embryo implantation and the maintenance of pregnancy.

Altered Expression of Interleukin-18 System mRNA at the Level of Endometrial Myometrial Interface in Women with Adenomyosis.

Adenomyosis is a uterine pathology characterized by a deep invasion of endometrial glands and stroma, disrupting the endometrial−myometrial interface (EMI). Interleukin-18 (IL-18) system is a dominant cytokine involved in the menstrual cycle of human endometrium. IL-18 may play a defensive role against maternal immune response in the uterine cavity.

Objective: To assess the effects of dienogest on segmented in vitro fertilization (IVF) and frozen-thawed embryo transfer (FET) for a patient with adenomyosis.

Case Report: A 33-year-old female with primary infertility for 3 years had dysmenorrhea and hypermenorrhea. Diagnosis of adenomyosis was made with a sonographic exam and an elevated cancer antigen 125 (CA-125, 310 U/mL).

Extracellular Vesicle-Associated MicroRNA-138-5p Regulates Embryo Implantation and Early Pregnancy by Adjusting GPR124.

Functional embryo-maternal interactions occur during the embryo implantation and placentation. Extracellular vesicles with microRNA (miR) between cells have been considered of critical importance for embryo implantation and the programming of human pregnancy. MiR-138-5p functions as the transcriptional regulator of G protein-coupled receptor 124 (GPR124).

Impact of growth hormone-releasing hormone antagonist on decidual stromal cell growth and apoptosis in vitro†.

Endometrial stromal cells remodeling is critical during human pregnancy. Growth hormone-releasing hormone and its functional receptor have been shown to be expressed in gynecological cancer cells and eutopic endometrial stromal cells. Recent studies have demonstrated the potential clinical uses of antagonists of growth hormone-releasing hormone as effective antitumor agents because of its directly antagonistic effect on the locally produced growth hormone-releasing hormone in gynecological tumors.

Supplementation with human menopausal gonadotropin in the gonadotropin-releasing hormone antagonist cycles of women with high AMH: Pregnancy outcomes and serial hormone levels.

Objective: To evaluate the value of using both HMG and recombinant FSH (r-FSH) in the GnRH antagonist protocol for women with high AMH.

Materials And Methods: This retrospective, single-center cohort study was conducted from January 2013 to December 2018. Of 277 GnRH antagonist IVF/ICSI cycles in women with anti-Mullerian hormone (AMH) ≥5 μg/L, 170 cycles receiving the combination of r-FSH and HMG (77 with HMG added at the beginning of the GnRH antagonist cycle and 93 with HMG added after GnRH antagonist administration) and 107 cycles receiving r-FSH alone were analyzed.

Association of family history with incidence and gestational hypertension outcomes of preeclampsia.

Background: Gestational hypertension and preeclampsia are hypertensive disorders related to pregnancy that can cause maternal morbidity and fetal growth retardation. The association of these disorders with family history remains unclear.

Objectives: To examine the degree of family aggregation of preeclampsia and gestational hypertension in Taiwan.

The potential role of assisted oocyte activation in the management of a POSEIDON group 3 patient with fertilization failure: A case report and literature review.

Objective: Assisted oocyte activation combined with ICSI (ICSI-AOA) has been reported to improve fertilization outcomes of couples with oocyte activation deficiency (OAD). Although there's no sufficient evidence to support ICSI-AOA as routine use, it might be beneficial for POSEIDON group 3 patients with suspected oocyte-related OAD.

Case Report: A 29-year-old female presented with a history of primary infertility for two years.

Gonadotropin-releasing hormone analogs: Mechanisms of action and clinical applications in female reproduction.

Extra-hypothalamic GnRH and extra-pituitary GnRH receptors exist in multiple human reproductive tissues, including the ovary, endometrium and myometrium. Recently, new analogs (agonists and antagonists) and modes of GnRH have been developed for clinical application during controlled ovarian hyperstimulation for assisted reproductive technology (ART). Additionally, the analogs and upstream regulators of GnRH suppress gonadotropin secretion and regulate the functions of the reproductive axis.

Obstetric and perinatal outcomes of pregnancy in patients with repeated implantation failure.

Objective: Despite the great advance of assisted reproductive technology (ART) in recent decades, many IVF patients failed to achieve a pregnancy even after multiple IVF-ET attempts. These patients are considered to have repeated implantation failure (RIF). While exhausting efforts have been devoted to the improvement of pregnancy rate in RIF patients, it is not clear whether RIF patients have aberrant obstetric or perinatal outcomes after they eventually achieved a pregnancy.

Application of non-invasive detection of peripheral vascular dysfunction in ovarian hyperstimulation syndrome (OHSS): A pilot study of clinical relevance.
