Abstract
Thin endometrium (TE) is defined as a mid-luteal endometrial thickness ≤7mm. TE can affect endometrial tolerance, leading to lower embryo implantation rates and clinical pregnancy rates, and is also associated with impaired outcomes from assisted reproductive treatment. Herein, we systematically review TE causes, mechanisms, and treatments. TE pathogenesis has multiple causes, with the endometrium becoming thinner with age under hormonal influence. In addition, uterine cavity factors are important, as the inflammatory environment may affect expressions of certain genes thereby inhibiting endometrial stromal cell proliferation and promoting apoptosis. Long-term oral contraceptive use or the use of ovulation-promoting drugs are also definite factors contributing to endometrial thinning. Other patients have primary factors, for which the clinical etiology remains unknown. The main therapeutic strategies available for TE are pharmacological (including hormonal and vasoactive drugs), regenerative medicine, intrauterine infusion of growth factor-granulocyte colony-stimulating factor, autologous platelet-rich plasma, and complementary alternative therapies (including traditional Chinese herbal medicine and acupuncture). However, the associated mechanisms of action are currently unclear. Clinical scholars have proposed various approaches to improve treatment outcomes in patients with TE, and are exploring the principles of efficacy, offering potentials for novel treatments. It is hoped that this will improve TE tolerance, increase embryo implantation rates, and help more couples with infertility with effective treatments.

Abstract
This study was conducted to compare dissolution profiles of four Jordanian registered sildenafil (SDF) products to the originator. Dissolution samples were analyzed utilizing a validated and stability-indicating HPLC method in human plasma. Validation was performed for specificity, linearity, limit of detection, lower limit of quantification, precision, trueness and stability. SDF was extracted from plasma samples using liquid-liquid extraction. The analysis was performed utilizing isocratic elution on C18 column with 1.0 ml/min flow rate. The regression value was ∼0.999 over 3 days with drug recovery between 86.6 to 89.8%with 10 ng/ml lower limit of quantitation. This method displayed a good selectivity of SDF with improved stability under various conditions. The method was used for SDF quantification in dissolution medium. Similarity factors for local products varied according to the used mediums, but all SDF local products passed the dissolution in vitro test since all of them showed a released of >85% after 60 min at the dissolution mediums.

Sodium alginate hydrogel integrated with type III collagen and mesenchymal stem cell to promote endometrium regeneration and fertility restoration. Int J Biol Macromol 2023; 253:127314. [PMID: 37827397 DOI: 10.1016/j.ijbiomac.2023.127314] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2023] [Revised: 09/15/2023] [Accepted: 10/06/2023] [Indexed: 10/14/2023]
Abstract
A thinner endometrium has been linked to implantation failure, and various therapeutic strategies have been attempted to improve endometrial regeneration, including the use of mesenchymal stem cells (MSCs). However, low survival and retention rates of transplanted stem cells are main obstacles to efficient stem cell therapy in thin endometrium. Collagen type III is a key component of the extracellular matrix, plays a crucial role in promoting cell proliferation and differentiation, and has been identified as the major collagen expressed at the implantation site. Herein, composite alginate hydrogel containing recombinant type III collagen (rCo III) and umbilical cord mesenchymal stem cells are developed. rCo III serves as favorable bioactive molecule, displaying that rCo III administration promotes MSCs proliferation, stemness maintenance and migration. Moreover, rCo III administration enhances cell viability and migration of mouse endometrial stromal cells (ESCs). In a mouse model of thin endometrium, the Alg-rCo III hydrogel loaded with MSCs (MSC/Alg-rCo III) significantly induces endometrial regeneration and fertility enhancement in vivo. Further studies demonstrate that the MSC/Alg-rCo III hydrogel promoted endometrial function recovery partly by regulating mesenchymal-epithelial transition of ESCs. Taken together, the combination of Alg-rCo III hydrogel and MSCs has shown promising results in promoting endometrium regeneration and fertility restoration, and may provide new therapeutic options for endometrial disease.

Abstract
OBJECTIVE To investigate the association of genetically proxied (using a surrogate biomarker) inhibition of phosphodiesterase 5 (PDE5), an established drug target for erectile dysfunction, with fertility, sexual behaviour, and subjective wellbeing. DESIGN Two sample cis-mendelian randomisation study. SETTING Summary data on genetic associations obtained from the International Consortium for Blood Pressure and UK Biobank. PARTICIPANTS Individuals of European ancestry from the International Consortium for Blood Pressure (n=757 601) for estimating PDE5 inhibition (using the surrogate biomarker of diastolic blood pressure reduction), and UK Biobank (n=211 840) for estimating the fertility, sexual behaviour, and subjective wellbeing outcomes in male participants. INTERVENTION Genetically proxied PDE5 inhibition. MAIN OUTCOME MEASURES Number of children fathered, number of sexual partners, probability of never having had sexual intercourse, and subjective wellbeing. RESULTS Genetically proxied PDE5 inhibition was associated with male participants having 0.28 (95% confidence interval 0.16 to 0.39) more children (false discovery rate corrected P<0.001). This association was not identified in female participants. No evidence was found of an association between genetically proxied PDE5 inhibition and number of sexual partners, probability of never having had sexual intercourse, or self-reported wellbeing in male participants. CONCLUSIONS The findings of this study provide genetic support for PDE5 inhibition potentially increasing the number of children fathered by male individuals. Absence of this association in female participants supports increased propensity for sustained and robust penile erections as a potential underlying mechanism. Further studies are required to confirm this, however, and these findings should not promote indiscriminate use of PDE5 inhibitors, which can also have harmful adverse effects.

Abstract
OBJECTIVE To evaluate whether Zi Gui Nv Zhen capsules (ZGNZC) can increase the fertility rate of Chinese women with infertility due to thin endometrium. METHODS Prospective, randomized, open-labeled 3-monthly study; 104 patients (aged 20-40 years) receiving either ZGNZC (experimental group, n = 55) or not (control group, n = 49). Main outcomes: thickness/type of the endometrium during ovulation and pregnancy rate. Between-group analysis (A) compares the experimental vs. control group, and within-group analysis (B) compares data at baseline and after study in the experimental group. RESULTS (A) Between-group-analysis: Patients with ZGNZC had a higher endometrium thickness (0.8 ± 0.27 vs. 0.68 ± 0.10; p < .05) and higher type A endometrium rates (34.2% vs. 13.2%; p < .05) than the control group. Pregnancy rates were higher in the experimental than in the control group (43.6% vs. 22.4%; p < .05). (B) Within-group-analysis: ZGNZC increased endometrium thickness (0.58 ± 0.13 vs. 0.87 ± 0.24 vs. 0.83 ± 0.26 vs. 0.80 ± 0.27), and type A endometrium rates (10.9% vs. 60.0% vs. 49.0% vs. 34.2%) (all p < .05). Univariate analysis of pregnancy with other study parameters showed positive and significant correlations between pregnancy and administration of ZGNZC (p < .05). All hepato-renal biomarkers remained within the norm. There were no adverse events. CONCLUSIONS In infertile women with thin endometrium who wish to conceive, two months' application of ZGNZC can improve endometrial properties and proliferation, which is necessary for a healthy pregnancy, and increase the clinical pregnancy rate in our prospective randomized observational study.

Abstract
The prevalence of pre-menopausal female infertility is increasing considerably due to various causes such as environmental pollutants, increased administration of chemotherapeutics and radiation exposure, microbial infections, and genetic/epigenetic alterations. However, the current therapeutical strategies remain unfavorite as the disadvantages are strongly challenging. Icariin (ICI) is a phytoestrogen that exerts some promising properties in order to alleviate female infertility. Therefore, the current literature review aimed to evaluate the conducted studies regarding the beneficial impacts of ICI on the female reproductive system and female fecundity. The findings of the present study revealed that ICI is able to modulate the levels of reproductive hormones as it causes a significant decrement in the levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) while increasing the levels of estrogen and progesterone. Furthermore, the administration of ICI results in a dramatic alteration in the expression of sex steroids’ receptors, particularly in female reproductive tissues. In addition, preserving ovarian follicular reserve, improving the ovarian and uterine histoarchitecture, elongating the estrous cycle duration, and eventually advancing the female fecundity are other major effects of ICI on the female reproductive system. Despite these desired beneficial properties, the current knowledge appears to be insufficient, hence further investigations, particularly on humans, are encouraged. To the best of our knowledge, this review provides a comprehensive information regarding the beneficial effects of Icariin on female infertility for the firs time.

Abstract
PURPOSE OF REVIEW Endometrial hypoproliferation refers to the failure of the endometrium to reach optimal thickness during fresh or frozen embryo transfer cycles in women undergoing infertility treatment with in-vitro fertilization (IVF). This review discusses the treatment options for endometrial hypoproliferation. RECENT FINDINGS Apart from factors related to the embryo quality, ultrasonographic findings associated with the endometrium, such as endometrial thickness, endometrial pattern and subendometrial blood flow, are considered key factors associated with the outcome of assisted reproductive treatment. To date, a consensus has not been reached regarding the definition of thin endometrium, while thresholds of 6, 7 or 8 mm have been used in the literature. Strategies to increase endometrial thickness can be reviewed in three groups: endocrine approaches, vitamins & supplements, and new experimental therapeutic interventions. Some of the recently introduced experimental therapeutic interventions such as platelet-rich plasma injection, stem cell treatment and tissue bioengineering are exciting potential therapies that need to be further studied. SUMMARY Despite a large number of publications on the topic, diagnosing and treating endometrial hypoproliferation remains a challenge. Well designed studies are needed to establish a widely accepted endometrial thickness cut-off value below which endometrial hypoproliferation is diagnosed and to generate meaningful data that would allow an evidence-based discussion of available therapeutic options with patients.

Abstract
PURPOSE This study aimed to compare the efficacy of a special kind of intrauterine balloon (IUB) and that of an intrauterine contraception device (IUD) for patients with intrauterine adhesions (IUAs) after transcervical resection of adhesion (TCRA). METHODS In this retrospective cohort study, after TCRA, 31 patients received a special IUB, and 38 patients received an IUD. The Fisher exact test, logistic regression method, Kaplan-Meier method and Cox proportional hazards regression model were used for statistical analysis. A two-sided value of P < 0.05 was considered statistically significant. RESULTS The readhesion rate significantly differed between the IUB group and IUD group, at 15.39% and 54.06%, respectively (P = 0.002). For recurrent moderate IUA, patients in the IUB group had lower scores than patients in the IUD group (P = 0.035). There was a significant difference in the intrauterine pregnancy rate of IUA patients in the IUB group and IUD group after treatment, with rates of 55.56% and 14.29%, respectively (P = 0.015). CONCLUSION Patients in the special IUB group had better outcomes than those in the IUD group, which has a certain guiding significance for clinical work.

Abstract
RESEARCH QUESTION To investigate the effects of two protocols (hormone replacement therapy (HRT) alone or in combination with tamoxifen) on the endometrium and pregnancy outcome of patients with thin endometrium in frozen-thawed embryo transfer (FET) cycles. DESIGN A total of 465 infertile patients with thin endometrium who underwent FET between January 2020 to June 2021 at the Drum Tower Hospital affiliated with Nanjing University Medical School were retrospectively analyzed. A total of 187 patients were given tamoxifen in addition to HRT (TMXF-HRT group), whereas 278 patients were given only HRT (HRT group). Clinical data were compared between the two groups, including general characteristics, endometrial thickness, and clinical pregnancy outcomes. RESULTS There were no significant differences in baseline characteristics of all enrolled patients between two groups. Serum progesterone (P) was higher in HRT group than in the TMXF-HRT group (0.28 ± 0.53 ng/mL vs. 0.15 ± 0.25 ng/mL, P = 0.002). There was a significant increase in endometrial thickness in the TMXF-HRT group compared with the HRT group (OR: 1.54, 95% CI: 1.32-1.75, P < 0.001). There were no significant differences in the clinical pregnancy rate, embryo implantation rate, early miscarriage rate, or live birth rate between these two groups. CONCLUSION Although tamoxifen when used in combination with hormone replacement therapy can significantly increase endometrial thickness, it may not have a role in improving the pregnancy outcomes of patients with thin endometrium undergoing FET cycles.

Abstract
Background Infertility is presently an emanating preventive medicine issue with some severe societal repercussions associated with it. In India, approximately a score percent of couples bear the burden of infertility. Moreover, the declining fertility rates despite effective artificial reproductive techniques and increasing development of modern reproductive medicine from the last two censuses pose an alarm to the demographic progression data. Many studies have highlighted the importance of shifting the research focus to endometrial receptivity for increasing clinical pregnancy. Objective This research aims to compare the efficacy of treatments of vaginal sildenafil citrate and granulocyte-colony stimulating factor (G-CSF) intrauterine injection in increasing endometrial thickness (ET). Methodology This was a randomized control trial (RCT) conducted over a two months period. Women seeking infertility treatment were recruited from the hospital's gynecological outpatient department (OPD). After the subjects gave informed consent, their history, clinical examination, and investigations were assessed. From the sixth day of the menstrual cycle, group A and group B had serial trans-vaginal ultra-sonographic evaluations for baseline endometrial thickness measurements. From day six to day 12 of the menstrual cycle, patients of group A were requested to self-administer per vaginal sildenafil citrate 25 mg every six hours. ET was evaluated sonographically on day 12 and day 14 of their menstrual cycle. Patients of group B received G-CSF 300 mcg/ml as intrauterine instillation on day 10 and were evaluated sonographically on day 12 and day 14 of their menstrual cycle. Patients then underwent additional therapy in the form of intrauterine injection (IUI), intracytoplasmic sperm injection with/without embryo transfer (ICSI/ET), or a natural cycle. Paired as well as unpaired t-tests were applied to the study groups to detect significant differences in the measurement of endometrial thickness before and after treatment. Results It was noticed that both sildenafil and G-CSF are agents for increasing endometrial thickness. The mean increase in endometrial thickness in the sildenafil treated group was 3.87 mm, while the mean increase in endometrial thickness in G-CSF treated group was 3.27 mm. Conclusion This study has evidence of better results in improving endometrial thickness in infertile women by using vaginal sildenafil with respect to endometrial growth with an intrauterine infusion of granulocyte colony-stimulating factor (filgrastim, G-CSF).

Effectiveness of phosphodiesterase type 5 inhibitors on the treatment of thin endometrium and pregnancy outcomes: An systematic review. JOURNAL OF ENDOMETRIOSIS AND PELVIC PAIN DISORDERS 2022.

Abstract
Phosphodiesterase type 5 (PDE5) inhibitors are thought to play a role in increasing endometrial thickness and increasing the success rate of pregnancy outcomes. This study was done to investigate the effects of PDE5 inhibitors on infertile women with thin endometrium and pregnancy outcomes. In this systematic review, all randomized controlled trials (RCTs) and observational studies were retrieved from databases including Institute for Scientific Information (ISI), PubMed, and Scopus by interesting keywords. A checklist was designed to collect necessary data and pregnancy outcomes, and the required items were recorded. PDE5 inhibitors through various mechanisms such as induction of vasodilatory effect through the effect on NO/cGMP signaling on vascular smooth muscle, through regulating cells proliferation and induction angiogenesis by increasing the expression of tumor suppressor factor (p53), and vascular endothelial growth factor A (VEGF-A) and downregulating inflammation by downregulating proinflammatory cytokines, affect endometrial thickness that eventually increases and pregnancy outcomes. Although PDE5s inhibitors increase endometrial thickness by different mechanisms, especially in women with thin endometrial, this does not necessarily mean that they induce a positive effect in all situations. However, their positive effects on pregnancy outcome may be affected by the time of administration, type of infertility treatment, underlying diseases such as pelvic disorders and inflammation. So in this regard, there are still ambiguous aspects that required further RCTs study in this area.

Abstract
AIMS Chemotherapeutic agents; cyclophosphamide (CYC) is used for treatment of cancer and autoimmune diseases. Grievously, CYC is non-selective as it affects both tumor and healthy cells resulting in systemic toxicity including placenta. The present study aimed to evaluate the effect of phosphodiesterase 5 inhibitor, sildenafil (Sild) on CYC-induced placental injury in rats. MATERIALS AND METHODS Thirty-two female Wister rats were randomly divided into 4 experimental groups. Group 1: control pregnant group; Group 2: Sild-treated pregnant rats; Group 3: pregnant rats received CYC; Group 4: pregnant rats received Sild and CYC. Placental malondialdehyde (MDA), total nitrite/nitrate (NOx), reduced glutathione (GSH), tumor necrosis factor-α (TNF-α), platelet growth factor (PlGF), c-Jun N-terminal kinase (JNK), p38 mitogen-activated protein kinase (p38MAPK), extracellular signal-regulated kinase (ERK) and cleaved caspase-3 were measured. Histological changes, Nuclear Factor kappa-light-chain-enhancer of activated B (NF-κB), Connexin 43 (GJA1) and proliferating cell nuclear antigen (PCNA) immuno-expressions were also evaluated. KEY FINDINGS CYC showed significant decrease in placental GSH, NOx, PlGF, GJA1 and PCNA immuno-expressions but significant increase in placental MDA, TNF-α, JNK, P38MAPK, ERK, caspase-3 and NF-kB immuno-expression. Sild showed significant improvement in all oxidative, inflammatory and apoptotic parameters. SIGNIFICANCE Sild is a promising protective drug against placental injury induced by CYC through antagonizing MAPK (JNK, ERK, and p38) signaling pathway with anti-oxidant, anti-inflammatory and anti-apoptotic effects.

Abstract
UNLABELLED Reproductive dysfunction is a multifactorial problem, for the correction of which the most difficult are cases of pathology comorbidity. Individual preconception preparation, taking into account risk factors, is recognized as an effective measure to increase the chances of conception and prevent reproductive losses. OBJECTIVE Optimization of treatment and rehabilitation measures at the preconception stage in patients with reproductive disorders. MATERIAL AND METHODS The effectiveness of the use of natural and preformed physical factors in the preconception preparation of 180 women who underwent medical and rehabilitation measures in the health resort of the Altai Territory - the resort town of Belokurikha (Group 1, 79 patients) and outpatient conditions in the city of Barnaul (Group 2, 101 patients). Comprehensive spa treatment included climatotherapy, a combination of various methods: balneotherapy, peloidtherapy, physiotherapy and a prolonged course of herbal medicine. RESULTS In patients of the 1st group, who underwent a course of rehabilitation treatment in a sanatorium-resort environment, compared with patients of the 2nd group, early reproductive losses were less common during pregnancy (7.1% and 20.7%, respectively; p=0.04) and more frequent term deliveries occurred (92.8% and 77.2%, respectively; p=0.02). The most significant predictors of the ineffectiveness of preconception preparation were the presence in patients of: chronic cystitis and autoimmune thyroiditis with hypothyroidism; oligomenorrhea at the time of pregnancy planning; aggravated by early reproductive losses and long-term wearing of intrauterine contraception history; burdened heredity for violation of carbohydrate metabolism. CONCLUSION Comprehensive preconception preparation in the sanatorium-resort conditions of Belokurikha helps to increase the fertility of patients with reproductive disorders, the trophostimulating effect in the genital organs and the restoration of endometrial reception, which makes it possible to recommend this method for use in clinical practice.

Abstract
The poor vascular development of an endometrium is the key cause of a thin endometrium due to the vascular endothelial growth factor (VEGF) decreasing in the glandular epithelium. Hence, inducing angiogenesis is an effective strategy for thin endometrium treatment in clinic. Herein, we developed a novel angiogenic hydrogel microsphere based on methacrylated hyaluronic acid (HAMA) loaded with VEGF for the treatment of a thin endometrium by a microfluidic electrospray technique. The generated HAMA microspheres with uniform size, porous structure, and satisfactory biocompatibility increased the drug-loading ability and controlled the drug-release rate by adjusting the hydrogel concentration. Besides, the HAMA microspheres loaded with VEGF showed satisfactory biocompatibility and promoted blood vessel formation in vitro. More importantly, the combination of HA and VEGF promoted new blood vessels and endometrial regeneration of a thin endometrium in vivo. Therefore, the combination of HA and VEGF would be conducive to the development of a drug-delivery microsphere with excellent biocompatibility and therapeutic effect for thin endometrium treatment and other biomedical applications.
