Abstract
INTRODUCTION Intravaginal drug delivery has emerged as a promising avenue for treating a spectrum of systemic and local female genital tract (FGT) conditions, using biomaterials as carriers or scaffolds for targeted and efficient administration. Much effort has been made to understand the natural barriers of this route and improve the delivery system to achieve an efficient therapeutic response. AREAS COVERED In this review, we conducted a comprehensive literature search using multiple databases (PubMed Scopus Web of Science Google Scholar), to discuss the potential of intravaginal therapeutic delivery, as well as the obstacles unique to this route. The in vitro cell models of the FGT and how they can be applied to probing intravaginal drug delivery are then analyzed. We further explore the limitations of the existing models and the possibilities to make them more promising for delivery studies or biomaterial validation. Complementary information is provided by in vitro acellular techniques that may shed light on mucus-drug interaction. EXPERT OPINION Advances in 3D models and cell cultures have enhanced our understanding of the FGT, but they still fail to replicate all variables. Future research should aim to use complementary methods, ensure stability, and develop consistent protocols to improve therapy evaluation and create better predictive in vitro models for women's health.

Abstract
At the onset of pregnancy, people with preexisting conditions face additional challenges in carrying their pregnancy to term, as the safety of the developing fetus and pregnant person is a significant factor of concern. Nanoparticle (NP)-based therapies have displayed success against various conditions and diseases in non-pregnant patients, but the use of NPs in maternal-fetal health applications needs to be better established. Local vaginal delivery of NPs is a promising administration route with the potential to yield high cargo retention in the vagina and improved therapeutic efficacy compared to systemic administration that results in rapid NP clearance by the hepatic first-pass effect. In this study, we investigated the biodistribution and short-term toxicity of poly(ethylene glycol)-poly(lactic-co-glycolic acid) (PEG-PLGA) NPs in pregnant mice following vaginal delivery. The NPs were either loaded with DiD fluorophores for tracking cargo distribution (termed DiD-PEG-PLGA NPs) or included Cy5-tagged PLGA in the formulation for tracking polymer distribution (termed Cy5-PEG-PLGA NPs). DiD-PEG-PLGA NPs were administered at gestational day (E)14.5 or 17.5, and cargo biodistribution was analyzed 24 h later by fluorescence imaging of whole excised tissues and histological sections. No gestational differences in DiD distribution were observed, so Cy5-PEG-PLGA NPs were administered at only E17.5 to evaluate polymer distribution in the reproductive organs of pregnant mice. Cy5-PEG-PLGA NPs distributed to the vagina, placentas, and embryos, whereas DiD cargo was only observed in the vagina. NPs did not impact maternal, fetal, or placental weight, suggesting they display no short-term effects on maternal or fetal growth. The results from this study encourage future investigation into the use of vaginally delivered NP therapies for conditions affecting the vagina during pregnancy.

Abstract
Endometriosis is an incurable gynecologic disease characterized by endometrial-like tissue growth outside of the uterine cavity. It affects approximately 10% of reproductive age women, who endure pelvic pain during periods and/or sexual intercourse and who suffer from reduced fertility and diminished quality of life due to the side effects of current treatments. To improve the management and prognosis of endometriosis patients, researchers have recently begun to develop nanoparticle-based diagnostics and treatments that are more effective and less invasive than existing approaches. This review discusses the current state of the field and highlights considerations for the continued development of nanotechnologies for the diagnosis and treatment of endometriosis.

Abstract
Gynaecological health is a neglected field of research that includes conditions such as endometriosis, uterine fibroids, infertility, viral and bacterial infections, and cancers. There is a clinical need to develop dosage forms for gynecological diseases that increase efficacy and reduce side effects and explore new materials with properties tailored to the vaginal mucosa and milieu. Here, we developed a 3D printed semisolid vaginal ovule containing pirfenidone, a repurposed drug candidate for endometriosis. Vaginal drug delivery allows direct targeting of the reproductive organs via the first uterine pass effect, but vaginal dosage forms can be challenging to self-administer and retain in situ for periods of more than 1-3 h. We show that a semisoft alginate-based vaginal suppository manufactured using semisolid extrusion additive manufacturing is superior to vaginal ovules made using standard excipients. The 3D-printed ovule showed a controlled release profile of pirfenidone in vitro in standard and biorelevant release tests, as well as better mucoadhesive properties ex vivo. An exposure time of 24 h of pirfenidone to a monolayer culture of an endometriotic epithelial cell line, 12Z, is necessary to reduce the cells' metabolic activity, which demonstrates the need for a sustained release formulation of pirfenidone. 3D printing allowed us to formulate mucoadhesive polymers into a semisolid ovule with controlled release of pirfenidone. This work enables further preclinical and clinical studies into vaginally administered pirfenidone to assess its efficacy as a repurposed endometriosis treatment.

Abstract
Leiomyomas, the most common benign neoplasms of the female reproductive tract, currently have limited medical treatment options. Drugs targeting estrogen/progesterone signaling are used, but side effects and limited efficacy in many cases are major limitation of their clinical use. Previous studies from our laboratory and others demonstrated that 2-methoxyestradiol (2-ME) is promising treatment for uterine fibroids. However, its poor bioavailability and rapid degradation hinder its development for clinical use. The objective of this study is to evaluate the in vivo effect of biodegradable and biocompatible 2-ME-loaded polymeric nanoparticles in a patient-derived leiomyoma xenograft mouse model. PEGylated poly(lactide-co-glycolide) (PEG-PLGA) nanoparticles loaded with 2-ME were prepared by nanoprecipitation. Female 6-week age immunodeficient NOG (NOD/Shi-scid/IL-2Rγnull) mice were used. Estrogen-progesterone pellets were implanted subcutaneously. Five days later, patient-derived human fibroid tumors were xenografted bilaterally subcutaneously. Engrafted mice were treated with 2-ME-loaded or blank (control) PEGylated nanoparticles. Nanoparticles were injected intraperitoneally and after 28 days of treatment, tumor volume was measured by caliper following hair removal, and tumors were removed and weighed. Up to 99.1% encapsulation efficiency was achieved, and the in vitro release profile showed minimal burst release, thus confirming the high encapsulation efficiency. In vivo administration of the 2-ME-loaded nanoparticles led to 51% growth inhibition of xenografted tumors compared to controls (P < 0.01). Thus, 2-ME-loaded nanoparticles may represent a novel approach for the treatment of uterine fibroids.

Development, characterization and evidence of anti-endometriotic activity of Phytocannabinoid-Rich nanoemulsions. Int J Pharm 2023; 643:123049.

Abstract
During the last decades, the cannabinoid research for therapeutic purposes has been rapidly advancing, with an ever-growing body of evidence of beneficial effects for a wide sort of conditions, including those related to mucosal and epithelial homeostasis, inflammatory processes, immune responses, nociception, and modulating cell differentiation. β-caryophyllene (BCP) is a lipophilic volatile sesquiterpene, known as non-cannabis-derived phytocannabinoid, with documented anti-inflammatory, anti-proliferative and analgesic effects in both in vitro and in vivo models. Copaiba oil (COPA) is an oil-resin, mainly composed of BCP and other lipophilic and volatile components. COPA is reported to show several therapeutic effects, including anti-endometriotic properties and its use is widespread throughout the Amazonian folk medicine. COPA was nanoencapsulated into nanoemulsions (NE), then evaluated regarding the potential for transvaginal drug delivery and providing endometrial stromal cell proliferation in vitro. Transmission electron microscopy (TEM) showed that spherical NE were obtained with COPA concentration that varied from 5 to 7 wt%, while surfactant was maintained at 7.75 wt%. Dynamic light scattering (DLS) measurements showed droplet sizes of 30.03 ± 1.18, 35.47 ± 2.02, 43.98 ± 4.23 and PdI of 0.189, 0.175 and 0.182, respectively, with stability against coalescence and Ostwald ripening during 90 days. Physicochemical characterization results suggest that NE were able to both improve solubility and loading capacity, and increase thermal stability of COPA volatile components. Moreover, they showed slow and sustained release for up to eight hours, following the Higuchi kinetic model. Endometrial stromal cells from non-endometriotic lesions and ectopic endometrium were treated with different concentrations of COPA-loaded NE for 48 h to evaluate its effect on cell viability and morphology. The results suggested significant decrease in cell viability and morphological modifications in concentrations higher than 150 μg/ml of COPA-loaded NE, but not when cells were treated with the vehicle (without COPA). Given the relevance of Copaifera spp. species in folk medicine and their bio economical importance in the Amazon, the development of novel formulations to overcome the technological limitations related to BCP and COPA, is promising. Our results showed that COPA-loaded NE can lead to a novel, uterus-targeting, more effective and promising natural alternative treatment of endometriosis.

Abstract
Adenomyosis is identified by the enlargement of the uterus secondary to such areas of the endometrium as the endometrial glands and stroma located deep in the myometrium, which causes its hyperplasia and hypertrophy. The most common signs of the development of adenomyosis in a patient are copious menstrual bleeding and dysmenorrhea. However, it should be borne in mind that in some patients, the disease may be asymptomatic. Despite the wide abundance of imaging and other diagnostic methods for diagnosing adenomyosis, there are currently no standard verified diagnostic criteria for pathologists. In addition, women with adenomyosis often have other concomitant gynaecological diseases, such as endometriosis or leiomyomas, which makes it difficult to diagnose and choose the optimal treatment for patients. Therefore, the purpose of this study was to highlight up-to-date and relevant information for the practitioner about the epidemiology, clinical manifestations, diagnostics and treatment options for adenomyosis. Sources from four databases (PubMed, Web of Science, Elsevier and Google Scholar) were used to search for data. As a result of a literature review, it was established that the "gold" standard for the diagnostics of adenomyosis is histological research methods, in particular, biopsy performed during hysteroscopy or laparoscopy, whereas imaging methods (transvaginal sonography, magnetic resonance imaging) are more often used for differential diagnostics of adenomyosis with other diseases. In addition, magnetic resonance imaging allows for a better differential diagnostics between adenomyosis and myomatosis and helps to recognise the disease at an early stage. Regarding treatment, there is currently no particular therapy and algorithms for the treatment of adenomyosis, which is primarily due to the lack of precise criteria for the diagnostics of the disease. However, the most effective therapeutic methods at the present stage are the use of aromatase inhibitors and gonadotropin-releasing hormone antagonists, whilst minimally invasive techniques, in particular, endometrial ablation and uterine artery embolisation, are becoming increasingly popular amongst surgical techniques.

Abstract
Common uterine diseases include endometriosis, uterine fibroids, endometrial polyps, endometrial hyperplasia, endometrial cancer, and endometrial dysfunction causing infertility. Patients with uterine diseases often suffer from abdominal pain, menorrhagia, infertility and other symptoms, which seriously impair their health and disturb their lives. Androgens play important roles in the normal physiological functions of the uterus and pathological progress of uterine diseases. Androgens in women are synthesized in the ovaries and adrenal glands. The action of androgens in the uterus is mainly mediated by its ligand androgen receptor (AR) that regulates transcription of the target genes. However, much less is known about the signaling pathways through which androgen functions in uterine diseases, and contradictory findings have been reported. This review summarizes and discusses the progress of research on androgens and the involvement of AR in uterine diseases. Future studies should focus on developing new therapeutic strategies that precisely target specific AR and their related signaling pathways in uterine diseases.

Abstract
Approaches for effective and sustained drug delivery to the female reproductive tract (FRT) for treating a range of gynaecological conditions remain limited. The development of versatile delivery platforms, such as soluble gels (sol–gels) coupled with applicators/devices, holds considerable therapeutic potential for gynaecological conditions. Sol–gel systems, which undergo solution-to-gel transition, triggered by physiological conditions such as changes in temperature, pH, or ion composition, offer advantages of both solution- and gel-based drug formulations. Furthermore, they have potential to be used as a suitable drug delivery vehicle for other novel drug formulations, including micro- and nano-particulate systems, enabling the delivery of drug molecules of diverse physicochemical character. We provide an anatomical and physiological perspective of the significant challenges and opportunities in attaining optimal drug delivery to the upper and lower FRT. Discussion then focuses on attributes of sol–gels that can vastly improve the treatment of gynaecological conditions. The review concludes by showcasing recent advances in vaginal formulation design, and proposes novel formulation strategies enabling the infusion of a wide range of therapeutics into sol–gels, paving the way for patient-friendly treatment regimens for acute and chronic FRT-related conditions such as bacterial/viral infection control (e.g., STDs), contraception, hormone replacement therapy (HRT), infertility, and cancer.

[PMID: 34276064 PMCID: PMC8277443 DOI: 10.1055/a-1369-9395] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2020] [Accepted: 01/20/2021] [Indexed: 12/24/2022] Open
Abstract
Intravaginal rings (IVRs) are minimally invasive polymeric devices specifically designed to be used for the sustained and prolonged release of various type of drugs such as hormones. One of the benefits of using topical drug delivery systems (e.g., IVRs) is the fact that systemic drug delivery may cause drug resistance due to elevated drug levels. Topical drug delivery also provides higher concentrations of the drug to the target site and has fewer side effects. In addition, when a drug is administered vaginally, the hepatic first-pass effect is avoided, resulting in higher absorption. Contraception and treatments for specific diseases such as endometriosis and hormone deficiencies can be improved by the administration of hormones via an IVR. This article aims to classify and compare various designs of commercially available and non-commercial hormonal IVRs and to analyze their performance. Current challenges affecting the development of IVRs are investigated, and
proposed solutions are discussed. A comprehensive search of publications in MEDLINE/PubMed and of commercial product data of IVRs was performed, and the materials, designs, performance, and applications (e.g., contraception, endometriosis, estrogen deficiency and urogenital atrophy) of hormonal IVRs were thoroughly evaluated. Most hormonal IVRs administer female sex hormones, i.e., estrogen and progestogens. In terms of material, IVRs are divided into 3 main groups: silicone, polyurethane, and polyethylene-co-vinyl acetate IVRs. As regards their design, there are 4 major designs for IVRs which strongly affect their performance and the timing and rate of hormone release. Important challenges include reducing the burst release and maintaining the bioavailability of hormones at their site of action over a prolonged period of administration as well as lowering production costs. Hormonal IVRs are a promising method which could be used to facilitate combination therapies by
administering multiple drugs in a single IVR while eliminating the side effects of conventional drug administration methods. IVRs could considerably improve womenʼs quality of life all over the world within a short period of time.

Abstract
AIM Given the increasing prevalence of hysteromyoma among the Chinese rural women of childbearing age, it is imperative that more attention should be given to researching risk factors that predispose women to this condition so that early preventive measures may be taken. Our study investigates potential risk factors for uterine fibroids such as participants' demographic characteristics (age, ethnicity, education), physiological characteristics (age at menarche, primiparous age), and the occurrence of several different female reproductive diseases (vaginitis, pelvic inflammatory disease). METHODS 2200 rural women of reproductive age were screened from a cross-sectional study carried out in the northern Anhui province. Data were collected by questionnaire surveys, gynecological and laboratory examinations and were subjected to univariate and multivariate analysis to evaluate the risk factors for uterine fibroids. RESULTS Of the 2200 women, 440 had uterine fibroids. In general, women with endometriosis, ovarian cysts and early menarche were more likely to suffer from hysteromyoma. Factors including higher parity, late age of first childbirth, and a regular menstrual cycle were associated with the reduced risk of uterine fibroids. CONCLUSIONS Our findings indicate that parameters such as earlier age of menarche, early primiparous age, lower parity and a variety of female reproductive diseases were associated with an increased risk of uterine fibroids. These findings may be used to guide the formulation of effective prevention and intervention protocols to improve the reproductive health of rural women.

Abstract
The use of nanoparticles (NPs) to deliver therapeutics to reproductive organs is an emerging approach to safely and effectively treat mothers and babies facing pregnancy complications. This study investigates the biodistribution of two different sized gold-based NPs in pregnant mice following systemic delivery as a function of gestational age. Poly(ethylene glycol)-coated 15 nm gold nanoparticles or 150 nm diameter silica core/gold nanoshells were intravenously administered to pregnant mice at gestational days (E)9.5 or 14.5. NP distribution was analyzed twenty-four hours later by inductively coupled plasma-mass spectrometry and silver staining of histological specimens. More NPs accumulated in placentas than embryos and delivery to these tissues was greater at E9.5 than E14.5. Neither NP type affected fetal weight or placental weight, indicating minimal short-term toxicity in early to mid-stage pregnancy. These findings warrant continued development of NPs as tools to deliver therapeutics to reproductive tissues safely.

Abstract
Endometriosis (EM) is a multifactorial and debilitating chronic benign gynecological disease, but the pathogenesis of the disease is not completely understood. Dysregulated expression of microRNAs (miRNA/miR) is associated with the etiology of EM due to their role in regulating endometrial stromal cell proliferation and invasion. The present study aimed to identify the functions and mechanisms underlying miR-143-3p in EM. To explore the role of miR-143-3p in EM, functional miRNAs were analyzed via bioinformatics analysis. miR-143-3p expression levels in endometriotic stromal cells (ESCs) and normal endometrial stromal cells (NESCs) were measured via reverse transcription-quantitative PCR. The role of miR-143-3p in regulating ESC proliferation and invasion was assessed by performing Cell Counting Kit-8 and Transwell assays, respectively. miR-143-3p expression was significantly upregulated in ESCs compared with NESCs. Functionally, miR-143-3p overexpression inhibited ESC proliferation and invasion, whereas miR-143-3p knockdown promoted ESC proliferation and invasion. Moreover, miR-143-3p inhibited autophagy activation in ESCs, as indicated by decreased green puncta, which represented autophagic vacuoles, decreased microtubule associated protein 1 light chain 3α expression and increased p62 expression in the miR-143-4p mimic group compared with the control group. Moreover, compared with the control group, miR-143-3p overexpression significantly decreased the expression levels of autophagy-related 2B (ATG2B), a newly identified target gene of miR-143-3p, in ESCs. ATG2B overexpression reversed miR-143-3p overexpression-mediated inhibition of ESC proliferation and invasion. Collectively, the results of the present study suggested that miR-143-3p inhibited EM progression, thus providing a novel target for the development of therapeutic agents against EM.

Abstract
In recent years, nanotechnology has revolutionized global healthcare and has been predicted to exert a remarkable effect on clinical medicine. In this context, the clinical use of nanomaterials for cancer diagnosis, fertility preservation, and the management of infertility and other pathologies linked to pubertal development, menopause, sexually transmitted infections, and HIV (human immunodeficiency virus) has substantial promise to fill the existing lacunae in reproductive healthcare. Of late, a number of clinical trials involving the use of nanoparticles for the early detection of reproductive tract infections and cancers, targeted drug delivery, and cellular therapeutics have been conducted. However, most of these trials of nanoengineering are still at a nascent stage, and better synergy between pharmaceutics, chemistry, and cutting-edge molecular sciences is needed for effective translation of these interventions from bench to bedside. To bridge the gap between translational outcome and product development, strategic partnerships with the insight and ability to anticipate challenges, as well as an in-depth understanding of the molecular pathways involved, are highly essential. Such amalgamations would overcome the regulatory gauntlet and technical hurdles, thereby facilitating the effective clinical translation of these nano-based tools and technologies. The present review comprehensively focuses on emerging applications of nanotechnology, which holds enormous promise for improved therapeutics and early diagnosis of various human reproductive tract diseases and conditions.

Abstract
INTRODUCTION Pharmacotherapy has a key role in the management of endometriosis. However, a significant proportion of patients gains only intermittent or limited benefits. In this regard, alternative and novel drug delivery methods are of paramount importance to improve efficacy and compliance of available treatments and develop alternative medical approaches. AREAS COVERED This review aims to provide the reader with a complete overview of available evidence about alternative and novel drug delivery methods for endometriosis pharmacotherapy and highlight new research lines. EXPERT OPINION Progestins and estroprogestins, which represent the first-line therapy, are already available in different formulations, being employed for contraception. Nevertheless, evidence on their adoption is still limited for some drug delivery methods, such as vaginal rings, patches, and subcutaneous implants. Further research is needed to define better their clinical utility in patients with endometriosis. Nanotechnologies have been investigated as novel drug delivery methods able to target the drug at the disease level. However, data are very limited and preliminary, and further research is needed to consider a possible clinical application in endometriosis.

Abstract
Pregnancy complications are commonplace and the challenges of treatment during pregnancy with few options available pose a risk to the health of both the mother and baby. Patients suffering from conditions such as preeclampsia, placenta accreta, and intrauterine growth restriction have few treatment options apart from emergency caesarean section. Fortunately, researchers are beginning to develop nanomedicine-based therapies that could be utilized to treat conditions affecting the mother, placenta, or fetus to improve the prognosis for mothers and their unborn children. This review summarizes the field's current understanding of nanoparticle biodistribution and therapeutic effect following systemic or vaginal administration and overviews the design parameters researchers should consider when developing nanomedicines for maternal/fetal health. It also describes safety considerations for nanomedicines to limit undesirable maternal or fetal side effects and discusses future work that should be performed to advance nanomedicine for maternal/fetal health. With additional development and implementation, the application of nanomedicine to treat pregnancy complications may mitigate the need for emergency caesarean sections and allow pregnancies to extend to term.

Abstract
Endometriosis is an oestrogen‐dependent, inflammation‐driven gynaecologic disorder causing severe disability. Endometriosis implants are characterized by unbalanced local oestrogen metabolism leading to hyperoestrogenism and aromatase up‐regulation is one of main mechanism involved. Aromatase inhibitors such as letrozole or anastrozole use in young women are associated with severely side effects limiting their long‐term clinical use. An endometriosis‐targeted inhibition of local aromatase could be a viable alternative, although the role of the local inhibition of this enzyme is still unclear. Using a new chick embryo allantoic membrane (CAM) model incorporating xenografted human endometriosis cyst, we showed that topical treatment with anastrozole reduced lesion size, although oestrogens produced by CAM female embryo blunted this effect. Xenografted human endometriosis CAM is a new efficient model for the screening of new drugs targeting endometriosis tissue.

Abstract
BACKGROUND Uterine fibroids represent the most common gynecological benign tumors in reproductive females. Acupuncture has been applied as a therapeutic modality in China to treat uterine fibroids. However, currently, few critical systematic reviews regarding the effect of acupuncture on uterine fibroids have been published. Our proposed review aims to evaluate the current evidence on the efficacy of acupuncture for uterine fibroids. METHODS A total of 7 databases were searched from their inception to December 2018, including PubMed, Medline, Embase, the Cochrane Central Register of Controlled Trials, the Chinese National Knowledge Infrastructure database, the Chinese Biomedical database, and the Wanfang database. The primary outcomes will be reduction in uterine volume and number of fibroids. Secondary outcomes are pelvic or low-back pain, assessed by Visual Analog Scale (VAS); Irregular menstrual periods; Low-abdominal pressure symptoms such as frequent or urgent urination, or constipation and adverse events. Data synthesis will be computed by RevManV.5.3.5 software when a data-analysis is allowed. Methodological quality will be evaluated with the risk of bias according to Cochrane Handbook. RESULTS This study will provide high-quality evidence of acupuncture for uterine fibroids. CONCLUSION The conclusion of this systematic review will provide evidence to judge whether acupuncture is an effective therapeutic intervention for patients with uterine fibroids. TRIAL REGISTRATION NUMBER PROSPERO CRD42019120484.

Abstract
In this review article, we will examine the history of polymers and their evolution from provisional World War II materials to medical therapeutics. To provide a comprehensive look at the current state of polymer-based therapeutics, we will classify technologies according to targeted areas of interest, including central nervous system-based and intraocular-, gastrointestinal-, cardiovascular-, dermal-, reproductive-, skeletal-, and neoplastic-based systems. Within each of these areas, we will consider several examples of novel, clinically available polymer-based therapeutics; in addition, this review will also include a discussion of developing therapies, ranging from the in vivo to clinical trial stage, for each targeted area of treatment. Finally, we will emphasize areas of patient care in need of more effective, accessible, and targeted treatment approaches where polymer-based therapeutics may offer potential solutions.
