Nurturing Hope: Reproductive Outcomes with Sinosomatics Following Unsuccessful IVF Attempts.

INTRODUCTION: For women who have experienced failed attempts at in vitro fertilization (IVF) and face medical issues leading to infertility, the renewed effort to seek fertility treatment, coupled with decreasing likelihood of success, can exert substantial emotional and physical strains. Consequently, many couples opt to discontinue treatment before attaining pregnancy. The objective of this study was to evaluate the reproductive outcomes in patients with unsuccessful prior IVF attempts who received a complementary treatment designed to alleviate emotional distress and burden. PATIENTS AND METHODS: A retrospective analysis of data from infertile patients who initiated the complementary intervention at a private clinic between January 2014 and December 2016 was conducted. Information on diagnosis, history of infertility, prior assisted reproductive technologies treatments, mode of conception, and pregnancy outcomes were retrieved. RESULTS: The data of 133 patients with a history of one or more unsuccessful IVF treatments were analyzed. Patients had an average age of 36.7 years (± 4.4 SD) and had been experiencing infertility for an average of 4.6 years (± 2.7 SD). The two main causes of their infertility were endometriosis (36.1%, 48 patients) and diminished egg quality (31.6%, 42 patients). By May 2020, a significant proportion of the patients, 81.2% (108 patients), had achieved pregnancy, leading to 94 live births, which represents a 70.7% success rate. These pregnancies mostly resulted from natural-cycle IVF (35.1%), donor cycles (23.4%), and conventional IVF (21.3%). The dropout rate was comparatively low at 23.3%. The median time from the start of complementary treatment to delivery was 18 months, with a range of 12 to 28 months. CONCLUSIONS: This study highlights the potential value of complementary treatment approaches in conjunction with standard medical care for women who have experienced unsuccessful IVF treatments in the past and thus face a reduced chance of motherhood. The reported 71% live birth rate is notably high, indicating that the inclusion of complementary treatments may provide women with past IVF failures a tangible opportunity for achieving successful pregnancy and childbirth. However, these findings need to be confirmed through randomized controlled studies.

Individual dynamics of uterine natural killer cells in natural and stimulated cycles monitored using a new endometrial dating method.

PROBLEM: It is important to evaluate the dynamics of uterine natural killer (uNK) cells in hormone replacement therapy (HRT) cycles, given their potential role in implantation and the common usage of HRT cycles with in vitro fertilization (IVF). METHOD OF STUDY: A total of 132 subfertile patients were evaluated during the secretory phase of either natural ovulation (OV) or HRT cycles, with two biopsies taken on approximately days 5 and 10 after ovulation/progesterone administration in a single menstrual cycle. Immunohistochemical Personal Endometrial Maturation Analysis (PEMA) was used to better quantify secretory-phase endometrial development, in combination with subsequent evaluation of uNK cell density. RESULTS: uNK cell density increased rapidly from the early to mid-secretory phase, with mean uNK densities of 113 and 117 per mm2 in first biopsies and 315 and 387 per mm2 in second biopsies for OV and HRT cycles, respectively. After reassessment of endometrial development with PEMA, the first and second biopsies in HRT and OV cycles were histologically dated to developmental ranges between days 15-20 (first biopsy) and days 19-25 (second biopsy). CONCLUSION: Subfertile women showed variable endometrial development in PEMA assessment, with uNK cell density correlating with the dating results. Overall, comparable levels of uNK cell density were observed in OV and HRT cycles. Importantly, uNK cell density depends on the histological maturation stage, with similar low coefficients of determination. This observation suggests that aberrant uNK cell results more likely reflect displaced endometrial maturation, rather than an intrinsic anomaly in uNK cell trafficking.

Endometrial delay is found to be part of a normal individual dynamic transformation process.

PURPOSE: Limited information is clinically available concerning endometrial receptivity; assessing endometrial transformation status is therefore an urgent topic in assisted reproductive technology. This study aimed to investigate individual endometrial transformation rates during the secretory phase in subfertile patients using personal endometrial transformation analysis. METHODS: Monitoring was carried out during the secretory phase to obtain endometrial receptivity profiles. For the investigation, two endometrial biopsies were taken within one menstrual cycle. The extended endometrial dating was based on the Noyes criteria, combined with immunohistochemical analyses of hormone receptors and proliferation marker Ki-67. Biopsies were taken mainly at days ovulation (OV, n = 76)/hormone replacement therapy (HRT, n = 58) + 5 and + 10. RESULTS: The results of the two biopsies were correlated with the clinically expected day of the cycle and showed temporal delays or hypercompensations, diverging from the expected cycle days by 0.5-5 days. In comparison with the first biopsies, the transformation rate in the second biopsies showed compensation, augmented delay, or constant transformation in 48.69, 22.37, and 28.94% of cases for ovulation in natural cycles and 56.89, 25.85, and 17.26% for HRT cycles, respectively. CONCLUSION: The study revealed an individually dynamic transformation process of the endometrium, with the ability to compensate or enlarge an initial "delay", which is now identified as a normal individual transformation process during the secretory phase. This information is of great importance for the scientific investigation of dynamic changes in endometrial tissue, as well as for the timing of embryo transfers.

The Physical, Psychological, and Social Day-to-Day Experience of Women Living With Endometriosis Compared to Healthy Age-Matched Controls-A Mixed-Methods Study.

Background: Endometriosis is characterized by lesions of endometrial tissue outside the uterus. Chronic pain is considered as main symptom, but challenges can relate to various physical, mental, and social aspects of the women's lives. The aim of our study was to gain a holistic understanding of the everyday reality of women with endometriosis compared to healthy controls. Methods: The total sample comprised 12 hormone-free endometriosis patients (EP) and 11 age-matched healthy women (HC). A mixed-methods design was used comprising semi-structured interviews, standardized questionnaires and a comprehensive diary to assess pain ratings and various mental and physical symptoms over the course of a menstrual cycle. Interviews were recorded, transcribed, and evaluated according to phenomenological analysis using the MAXQDA software. Results: Interviews showed that living with endometriosis was associated with an impairment in everyday life. Physical strains, especially pain, high levels of psychological distress, and social limitations have been reported. Living with endometriosis affected the patients' personality and they "no longer felt like themselves." Physical and psychological symptoms were reported to interfere with social interaction and participation. Evaluation of the standardized questionnaires revealed significant impairments in EP compared to HC in regard to anxiety and depression scores (both p < 0.001; Hospital Anxiety and Depression Scale), mental and physical quality of life (both p < 0.001; Short-Form Health Survey-12), stress ratings (p < 0.001; Patient Health Questionnaire-15) and functional well-being (p < 0.001; Functional Well-being-7). The highest levels of mean pelvic pain and dyschezia were observed in EP during menstruation, but mean pain ratings and dyschezia were increased in EPs compared to HP during the whole cycle. EP reported mental symptoms (e.g., depressed mood or anxiety) mainly during menstruation, while HC did not show any mental symptoms during the cycle. In addition, physical symptoms were elevated during the entire cycle in EPs (all p < 0.01). Discussion: The mixed-methods approach enabled to interpret the interviews, the standardized questionnaires, and the symptom diary in a broader context of everyday life. The symptoms do not appear to act independently, but rather influence each other. This leads to a complex interplay of physical, mental, and social impairments, with pain often being the starting point.

Endometrial Dating Method Detects Individual Maturation Sequences During the Secretory Phase.

BACKGROUND/AIM: This study assessed whether a new immunohistochemical dating method allows precise endometrial dating allowing optimal timing for embryo transfer. PATIENTS AND METHODS: A novel method was used for endometrial dating, with parameters including menstrual cycle days, Noyes histological criteria, along with immunohistochemical expression pattern of estrogen and progesterone receptors and proliferation marker Ki-67. Endometrial maturation was analyzed on days +5 to +10 after ovulation or progesterone administration in 217 biopsies from 151 subfertile patients during the secretory phase. RESULTS: Endometrial maturation varied individually, occurring 1.68±1.67 days late. Comparison of histological maturation with clinical days after ovulation showed a delay of about 2 days. CONCLUSION: Endometrial maturation requires 8 days, rather than the expected 6 days, to reach the histological mid-secretory phase. This is not a delay and is also seen in fertile patients. The new analysis method used is superior to that using Noyes criteria alone and provides a better basis for determining conditions for optimal timing of embryo transfers.

Psychotherapy With Somatosensory Stimulation for Endometriosis-Associated Pain: The Role of the Anterior Hippocampus.

BACKGROUND: Endometriosis is a gynecological disorder affecting 6%-10% of all women in their reproductive age. There is an emerging view in the literature that psychological trauma plays a central role in the pathogenesis of pelvic pain, one of the core symptoms of endometriosis. Here we report central nervous system mechanisms of a novel combination of psychotherapy and somatosensory stimulation that has recently shown remarkable effects in reducing pain, anxiety, and depressive symptoms in these patients. METHODS: We conducted a randomized controlled trial; 67 patients with severe endometriosis-associated pain (maximum pain: 7.6 ± 2.0, average pain: 4.5 ± 2.0 on a 10-point numeric rating scale) were included in the study and randomly allocated to intervention (35 patients) or waitlist control (32 patients) groups. Resting-state functional magnetic resonance imaging was used to assess brain connectivity of these patients at baseline, after 3 months of therapy, and after 6 months. The analysis focused on the hippocampus. RESULTS: We identified a cortical network comprising the right anterolateral hippocampus-a region modulating the hypothalamic-pituitary-adrenal axis-and somatosensory, viscerosensory, and interoceptive brain regions. Regression analysis showed that reduction in connectivity predicted therapy-induced improvement in patients׳ anxiety. CONCLUSIONS: We have identified a putative neurobiological mechanism underlying the potent combination of psychotherapy and somatic stimulation in treating symptoms of endometriosis.

Psychotherapy With Somatosensory Stimulation for Endometriosis-Associated Pain: A Randomized Controlled Trial.

OBJECTIVE: To evaluate whether psychotherapy with somatosensory stimulation is effective for the treatment of pain and quality of life in patients with endometriosis-related pain. METHODS: Patients with a history of endometriosis and chronic pelvic pain were randomized to either psychotherapy with somatosensory stimulation (ie, different techniques of acupuncture point stimulation) or wait-list control for 3 months, after which all patients were treated. The primary outcome was brain connectivity assessed by functional magnetic resonance imaging. Prespecified secondary outcomes included pain on 11-point numeric rating scales (maximal and average global pain, pelvic pain, dyschezia, and dyspareunia) and physical and mental quality of life. A sample size of 30 per group was planned to compare outcomes in the treatment group and the wait-list control group. RESULTS: From March 2010 through March 2012, 67 women (mean age 35.6 years) were randomly allocated to intervention (n=35) or wait-list control (n=32). In comparison with wait-list controls, treated patients showed improvements after 3 months in maximal global pain (mean group difference -2.1, 95% confidence interval [CI] -3.4 to -0.8; P=.002), average global pain (-2.5, 95% CI -3.5 to -1.4; P<.001), pelvic pain (-1.4, 95% CI -2.7 to -0.1; P=.036), dyschezia (-3.5, 95% CI -5.8 to -1.3; P=.003), physical quality of life (3.8, 95% CI 0.5-7.1, P=.026), and mental quality of life (5.9, 95% CI 0.6-11.3; P=.031); dyspareunia improved nonsignificantly (-1.8, 95% CI -4.4 to 0.7; P=.150). Improvements in the intervention group remained stable at 6 and 24 months, and control patients showed comparable symptom relief after delayed intervention. CONCLUSION: Psychotherapy with somatosensory stimulation reduced global pain, pelvic pain, and dyschezia and improved quality of life in patients with endometriosis. After 6 and 24 months, when all patients were treated, both groups showed stable improvements. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov, https://clinicaltrials.gov, NCT01321840.

Improving fertility preservation in cancer: ovarian tissue cryobanking followed by ovarian stimulation can be efficiently combined.

This pilot study evaluated whether combination of partial removal of ovarian tissue for cryobanking followed by ovarian stimulation and cryopreservation of oocytes can improve the efficacy of fertility preservation without further delaying cancer treatment. Initial partial removal of ovarian tissue did not substantially affect the average number and quality of retrieved oocytes after ovarian stimulation in this study.

Ovarian stimulation to cryopreserve fertilized oocytes in cancer patients can be started in the luteal phase.

OBJECTIVE: To analyze if oocytes can be obtained in all patients before cancer treatment within 2 weeks by initiating ovarian stimulation during the follicular or luteal phase. DESIGN: Prospective controlled multicenter trial. SETTING: Four university-based centers. PATIENT(S): Forty cancer patients before chemotherapy. INTERVENTION(S): Twenty-eight patients were stimulated with gonadotropins in the follicular phase (group I). In 12 patients (group II), ovarian stimulation was initiated in the luteal phase, and these received GnRH antagonists and recombinant FSH. In 14 patients, 143 oocytes were further processed for fertilization by intracytoplasmic sperm injection (ICSI). MAIN OUTCOME MEASURE(S): Number of oocytes aspirated after ovarian stimulation, cumulative FSH/hMG dosage, viability and maturity of oocytes, and fertilization rate by ICSI. RESULT(S): Patients in group I (age 27.6 +/- 4.9 yrs) were stimulated on average for 10.6 days, and patients in group II (age 31.2 +/- 5.7 yrs) for 11.4 days. Total amount of FSH was on average 2,255 IU (I) and 2,720 IU (II) per patient. Average and median numbers of aspirated oocytes were, respectively, 13.1 and 11.5 (I) versus 10.0 and 8.5 (II); 83.7% (I) and 80.4% (II) of the oocytes were mature and viable and could be treated by ICSI. Fertilization rate was 61.0% (I) versus 75.6% (II). CONCLUSION(S): This pilot study suggests that oocytes can be obtained before cancer treatment efficiently irrespective of the phase of the menstrual cycle.

The long pentraxin PTX3 in human endometrium: regulation by steroids and trophoblast products.

Human implantation is characterized by blastocyst attachment to endometrial epithelial cells followed by invasion of trophoblast into the maternal decidua. There has been an increasing amount of data linking higher levels of the pentraxin PTX3, a long pentraxin, to embryo implantation. PTX3 levels were found to be higher in patients with preeclampsia and intrauterine growth restriction, both conditions caused by faulty implantation. Furthermore, PTX3 knockout mice have reduced fertility due to cumulus oopherus malformation as well as implantation failure. In a human implantation model, we and others have shown that trophoblast action on endometrial stromal cells induces PTX3 expression. In this study, we analyzed PTX3 expression throughout the menstrual cycle as well as its regulation by hormones involved in the implantation process. We also compared PTX3 expression in stromal cells induced by trophoblast conditioned medium to its induction by trophoblast coculture. PTX3 mRNA expression in human endometrial stromal cells is regulated by progesterone, estrogen, and IL-1 but not human chorionic gonadotropin and is increased by both trophoblast-conditioned medium as well as trophoblast explants. PTX3 protein production and regulation by these factors is shown by Western blot. Based on these findings, we conclude that estradiol and progesterone are involved in PTX3 induction and regulation during implantation. Also, of the factors secreted by trophoblast, IL-1beta induces PTX3 in human endometrial stromal cells.

Gene expression profiling of human endometrial-trophoblast interaction in a coculture model.

Investigating the interaction of human endometrium and trophoblast during implantation is difficult in vitro and impossible in vivo. This study was designed to analyze the effect of trophoblast on endometrial stromal cells during implantation by comprehensive gene profiling. An in vitro coculture system of endometrial stromal cells with first-trimester trophoblast explants was established. Trophoblast and endometrial stromal cells were separated after 24 h. Gene expression of endometrial stromal cells after coculture was compared with the gene expression of endometrial stromal cells cultured alone by microarray analysis. We confirmed the expression of distinct genes using real-time PCR. Genes up-regulated included those for inflammatory response, immune response, and chemotaxis (pentraxin-related gene 3, chemokine ligands, IL-8, IL-1 receptors, IL-18 receptor, IL-15, IL-15 receptor, TNF-alpha-induced protein 6, and IL-6 signal transducer), regulators of cell growth (IGF-binding proteins 1 and 2) and signal transduction. Also up-regulated were genes for growth and development, glucose metabolism, and lipid metabolism: DKK-1, WISP, IGF-II, hydroxysteroid 11beta-dehydrogenase 1, hydroxyprostaglandin dehydrogenase 15, prostaglandin E synthase, prostaglandin F receptor, aldehyde dehydrogenase 1 family, member A3 and phosphatidic acid phosphatase type 2B. Other genes included genes for cell-cell signaling (pre-B-cell colony-enhancing factor 1), proteolysis, calcium ion binding, regulation of transcription, and others. Down-regulated genes included genes for proteolysis (MMP-11 and mitochondrial intermediate peptidase), genes for cell death (caspase 6, death-associated protein kinase 1, and histone deacetylase 5), transcription factors (sex determining region Y-box 4, dachshund homolog 1, ets variant gene 1, and zinc finger protein 84 and 435), and genes for humoral immune response (CD24 antigen). Trophoblast has a significant impact on endometrial stromal cell gene expression. Some of the genes regulated by trophoblast in endometrial stromal cells are already known to be regulated by progesterone and show the endocrine function of trophoblast during pregnancy. Others are genes so far unknown to play a role in endometrial-trophoblast interaction and open a wide field of investigation.

Galectin-9: a new endometrial epithelial marker for the mid- and late-secretory and decidual phases in humans.

CONTEXT: The galectin family has been reported to play a role in the regulation of cell growth, cell adhesion, apoptosis, inflammation, and immunomodulation, all of which are important for endometrial function, as well as implantation. OBJECTIVE: The objective of the study was to investigate the expression and regulation of galectin-9, a beta-galactoside-binding lectin in the human endometrium. DESIGN: Galectin-9 mRNA and protein were analyzed in dated endometrial biopsies throughout the menstrual cycle and in human early-pregnancy decidua, as well as in the different endometrial cell compartments. Regulation of galectin-9 by estradiol, progesterone, epidermal growth factor, and interferon-gamma in endometrial epithelial cells in vitro was studied. RESULTS: Galectin-9 mRNA analyzed by RNase protection assay is expressed in the human endometrium, specifically in the human endometrial epithelial cells but not in stromal or immune cells. It is expressed at very low concentrations during the proliferative phase and the early-secretory phase and shows a sharp and significant increase in the mid- and late-secretory phases, the window of implantation, as well as in the decidua. Accordingly, galectin-9 protein is also exclusively increased in human endometrial epithelial cells during the mid- and late-secretory phases and in the decidua, however, not in endometrial stromal cells or decidualized cells in vivo or in vitro. A regulation in vitro by estradiol, progesterone, epidermal growth factor, and interferon-gamma could not be detected. CONCLUSIONS: Based on these findings and on the functional studies of other galectins, we suggest galectin-9 as a novel endometrial marker for the mid- and late-secretory and decidual phases.
