The COVID-19 pandemic caused by SARS-CoV-2 has presented numerous health challenges, including long-term COVID, which affects female reproductive health. This review consolidates the current research on the impact of SARS-CoV-2 on the menstrual cycle, ovarian function, fertility, and overall gynecological health. This study emphasizes the role of angiotensin-converting enzyme receptors in viral entry and the subsequent tissue-specific pathological effects. It also explores the potential influence of long COVID on hormonal balance and immune responses, contributing to menstrual irregularities and impaired ovarian function. The findings indicate a higher prevalence of long-term COVID-19 among women, highlighting the substantial implications for reproductive health and the need for sex-sensitive longitudinal studies. Enhanced surveillance and targeted research are essential to develop effective interventions that prioritize women\'s reproductive well-being following SARS-CoV-2 infection. This review advocates for a sex-informed approach to ongoing COVID-19 research and healthcare strategies, aiming to provide up-to-date and pertinent data for healthcare providers and the general public, ultimately improving outcomes for females affected by long COVID.

In April 2023, the World Health Organization (WHO) reported that 17.5% of the global adult population experience infertility. What may be the contribution of per-and polyfluoroalkyl (PFAS) to this global public health problem? This study explored the associations between in vitro fertilization (IVF) outcomes and plasma concentrations of individual PFAS and PFAS mixtures in women undergoing in vitro fertilization and embryo transfer (IVF-ET) and how these exposures might affect IVF outcomes. We analyzed 8 PFASs in plasma samples from women (N = 259) who underwent IVF treatment. In multivariable generalized linear mixed models, there were statistically significant associations of higher plasma concentrations of PFNA with reduced numbers of total retrieved oocytes [12.486 (95%CI: 0.446,25.418), p trend = 0.017], 2 PN zygotes [6.467(95%CI: 2.034,14.968), p trend = 0.007], and cleavage embryos [6.039(95%CI: 2.162,14.240), p trend = 0.008]. Similarly, there was a continuous decline in the numbers of retrieved 2 PN zygotes and cleavage embryos with increasing concentration of PFOS [6.467(95%CI: 2.034,14.968), p trend = 0.009 and 6.039(95%CI: 2.162,14.240), p trend = 0.031,respectively] and a negative association between PFHxS concentrations and clinical pregnancy during the initial cycles of frozen ET [0.525(95%CI:0.410,0.640), p trend = 0.021]. To investigate the joint effect of PFAS mixtures, a confounder-adjusted BKMR model analysis showed inverse relationship between PFAS mixtures and the number of high-quality embryos, 2 PN zygotes and cleavage embryos, to which the greatest contributors to the mixture effect are PFDeA and PFBS, respectively. It demonstrated that PFAS exposure might exert negative effects on oocyte yield, fertilization and high-quality embryo in women undergoing IVF. These findings suggest that exposure to PFAS may increase the risk of female infertility and further studies are needed to uncover the potential mechanisms underlying the reproductive effects associated with PFAS.

Polycystic Ovary Syndrome (PCOS) is one of the most widespread endocrine and metabolic disorders affecting women of reproductive age. Major symptoms include hyperandrogenism, polycystic ovary, irregular menstruation cycle, excessive hair growth, etc., which sometimes may lead to more severe complications like infertility, pregnancy complications and other co-morbidities such as diabetes, hypertension, sleep apnea, etc. Early detection and effective management of PCOS are essential to enhance patients\' quality of life and reduce the chances of associated health complications. Artificial intelligence (AI) techniques have recently emerged as a popular methodology in the healthcare industry for diagnosing and managing complex diseases such as PCOS. AI utilizes machine learning algorithms to analyze ultrasound images and anthropometric and biochemical test result data to diagnose PCOS quickly and accurately. AI can assist in integrating different data sources, such as patient histories, lab findings, and medical records, to present a clear and complete picture of an individual\'s health. This information can help the physician make more informed and efficient diagnostic decisions. This review article provides a comprehensive analysis of the evolving role of AI in various aspects of the management of PCOS, with a major focus on AI-based diagnosis tools.

The microbiome plays a critical role in the process of conception and the outcomes of pregnancy. Disruptions in microbiome homeostasis in women of reproductive age can lead to various pregnancy complications, which significantly impact maternal and fetal health. Recent studies have associated the microbiome in the female reproductive tract (FRT) with assisted reproductive technology (ART) outcomes, and restoring microbiome balance has been shown to improve fertility in infertile couples. This review provides an overview of the role of the microbiome in female reproductive health, including its implications for pregnancy outcomes and ARTs. Additionally, recent advances in the use of microbial biomarkers as indicators of pregnancy disorders are summarized. A comprehensive understanding of the characteristics of the microbiome before and during pregnancy and its impact on reproductive health will greatly promote maternal and fetal health. Such knowledge can also contribute to the development of ARTs and microbiome-based interventions.

Ayurveda, an ancient holistic and personalized healing system originating from the Indian subcontinent, has been gaining increasing attention as a complementary and alternative medical practice for treating various health conditions, including those related to women\'s reproductive well-being. This comprehensive literature review examines a wide array of experimental and clinical studies exploring the diverse facets of Ayurvedic interventions in addressing issues such as menstrual irregularities, polycystic ovary syndrome (PCOS), infertility, and menopausal symptoms. The paper specifically focuses on discussing the available data regarding the efficacy of Tulsi (Ocimum tenuiflorum), ashwagandha (Withania somnifera), ginger (Zingiber officinale), cardamom (Elettaria cardamomum), turmeric (Curcuma longa), and Shatavari (Asparagus racemosus), which have traditionally been used in Ayurvedic medicine for centuries. The synthesis of literature not only highlights the potential benefits of these Ayurvedic interventions, but also critically assesses the methodological rigor of existing studies, identifying research gaps, and proposing directions for future investigations. While acknowledging the need for further rigorous research and clinical trials, the review emphasizes the benefits of collaborative and integrative healthcare. This review aims to serve as a valuable resource for healthcare practitioners, researchers, and individuals seeking holistic and natural alternatives for female reproductive health management.

Disruption of women\'s gut and cervicovaginal microbiota has been associated with multiple gynaecological diseases such as endometriosis, polycystic ovary syndrome, non-cyclic pelvic pain and infertility. Female infertility affects 12.6% of women worldwide; its aetiology is complex and multifactorial and can be underpinned by uterine pathologies, systemic diseases and age. In addition, a new perspective has emerged on the role of the gut and vaginal microbiomes in reproductive health. Research shows that the administration of precisely selected probiotics, often in combination with prior antibiotic treatment, may facilitate the restoration of symbiotic microbiota to increase successful conception and assisted reproductive technology outcomes. However, clarity on this issue from fuller research is currently hampered by a lack of consistency and harmonization in clinical studies: various lactobacilli and bifidobacteria species have been delivered through both the oral and vaginal routes, in different dosages, for different treatment durations. This commentary explores the intricate relationship between the microbiota in the cervicovaginal area and gut of women, exploring their potential contribution to infertility. It highlights ongoing research on the use of probiotic formulations in improving pregnancy outcomes, critically examining the divergent findings in these studies, which complicate a conclusive assessment of the efficacy of these interventions.

Clinically, a Lactobacillus rich vaginal microbiota (VMB) is considered optimal for reproductive outcomes, while a VMB populated by anaerobes is associated with dysbiosis and the clinical condition bacterial vaginosis (BV), which is linked to increased susceptibility to sexually transmitted infections and adverse reproductive outcomes. Mouse models that mimic eubiotic and dysbiotic VMB are currently lacking but could play a critical role in improving protective interventions.
In this study, probiotic, eubiotic, and dysbiotic models were developed in C57BL/6 mice, using probiotic strains Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14, eubiotic Lactobacillus crispatus, or dysbiotic Gardnerella vaginalis strains. Endogenous sex hormones were manipulated by either ovariectomizing (OVX) mice or administering 17β-estradiol or progesterone pellets in OVX mice. Hormone-altered mice were inoculated with probiotic Lactobacillus species, L. crispatus, or G. vaginalis, and colonization was tracked using quantitative plating assays. Glycogen and MUC-1 levels in hormone-treated mice were determined with ELISA and MUC-1 staining.
Following a single administration, L. rhamnosus and L. reuteri persisted in the mouse vaginal tract for up to eight days, L. crispatus persisted for up to three days, and G. vaginalis persisted for up to two days, as measured by quantitative plating assays and qPCR. Colonization of G. vaginalis was facilitated by the presence of mucin. The lack of endogenous hormones in OVX mice dramatically decreased VMB bacterial load compared to normal mice. None of the exogenous bacteria including Lactobacilli could colonize OVX mice for more than 24 hours. Treatment with 17β-estradiol but not progesterone restored the endogenous VMB and colonization with Lactobacilli and G. vaginalis. Interestingly, 17β-estradiol treated mice had significantly increased levels of glycogen compared to OVX and progesterone-treated mice.
Based on the results, we have shown that estrogen played a significant role in the ability for human VMB species to colonize in our mouse models, potentially through a glycogen mediated mechanism. These results suggest there is a dynamic interaction between sex hormones and the VMB, which can affect bacterial diversity and the ability for a VMB to colonize.

Background Medical termination of pregnancy (MTP) pills, primarily comprising mifepristone and misoprostol, have proven highly effective and safe under medical supervision. However, unsupervised MTP pill use is on the rise, posing serious health risks. Unsafe abortions remain a global public health concern, with a high incidence in developing countries like India. Methods We conducted a cross-sectional study at a tertiary healthcare center in India from February to April 2023. We enrolled 150 women with a history of unsupervised MTP pill use. Data were collected using structured questionnaires, including demographic information, awareness, sources of information, reasons for self-medication, and knowledge of complications. Results The majority of participants (50%) were aged 25-29 years. Low-income women (<3000pc) constituted 46.66% of the sample. Husbands played a significant role in advocating MTP pill use (57.33%). Ninety percent of pills were obtained directly from pharmacies. Shockingly, 97.3% of women were unaware of MTP pill complications, and 84% did not follow the recommended regimen. Significant associations were found between income, religion, education, age, parity, and reasons for self-medication, as well as recommendations for MTP pill use. Conclusion Our study revealed a diverse demographic of women seeking unsupervised MTP pill intake. Low-income women were disproportionately affected, emphasizing the need for improved healthcare access and education. Husbands played a crucial role in advocating MTP pill use, highlighting the importance of including men in reproductive health discussions. Lack of awareness and non-adherence to recommended regimens posed substantial risks. To combat unsafe abortions, a multifaceted approach is needed. Reproductive health education, regulatory measures, improved healthcare accessibility, and tailored interventions are essential.

BACKGROUND: Disinfection byproducts (DBPs) as ovarian toxicants have been documented in toxicological studies. However, no human studies have explored the effects of exposure to DBPs on diminished ovarian reserve (DOR).
OBJECTIVE: To assess whether urinary biomarkers of exposure to drinking-water DBPs were associated with DOR risk.
METHODS: A total of 311 women undergoing assisted reproductive technology were diagnosed with DOR in the Tongji Reproductive and Environmental (TREE) cohort from December 2018 to August 2021. The cases were matched to the controls with normal ovarian reserve function by age in a ratio of 1:1. Urinary trichloroacetic acid (TCAA) and dichloroacetic acid (DCAA) were quantified as biomarkers of drinking-water DBP exposures. The conditional logistic regression and restricted cubic spline (RCS) were used to explore urinary biomarkers of drinking-water DBP exposures in associations with the risk of DOR.
RESULTS: Elevated urinary DCAA levels were associated with higher DOR risk [adjusted odds ratio (OR) = 1.87; 95 % confidence interval (CI): 1.16, 3.03 for the highest vs. lowest quartiles; P for trend = 0.016]. The association was confirmed in the RCS model, with a linear dose-response curve (P for overall association = 0.029 and P for non-linear association = 0.708). The subgroup analysis by age and body mass index (BMI) showed that urinary DCAA in association with DOR risk was observed among women ≥35 years old and leaner women (BMI < 24 kg/m2), but the group differences were not statistically significant. Moreover, a U-shaped dose-response curve between urinary TCAA and DOR risk was estimated in the RCS model (P for overall association = 0.011 and P for non-linear association = 0.004).
CONCLUSIONS: Exposure to drinking-water DBPs may contribute to the risk of DOR among women undergoing assisted reproductive technology.

UNASSIGNED: Female reproductive health is recognized as a predictor of morbidity, mortality, and quality of life, although data in the setting of chronic kidney disease (CKD) are limited.
UNASSIGNED: A mixed-methods study was employed. Phase 1 was an anonymous, internet-based survey. Phase 2 was semistructured interviews offered to all respondents upon survey completion.
UNASSIGNED: The survey was disseminated internationally from October 4, 2021, to January 7, 2022, to individuals aged 18-50 years with both a uterus and CKD diagnosis.
UNASSIGNED: Menstrual health and contraceptive use by CKD stage (dialysis, nondialysis CKD, and transplant).
UNASSIGNED: Survey data were analyzed using descriptive statistics. Interview data were analyzed using the framework method of analysis.
UNASSIGNED: Of 152 respondents, 98 (mean age 33 ± 0.7 years; n = 20 dialysis, n = 59 nondialysis CKD, n = 19 transplant) satisfied the inclusion criteria, representing 3 continents. The most common causes of CKD among survey respondents were hereditary causes in dialysis (n = 6, 30%) and glomerulonephritis in nondialysis CKD (n = 22, 37%) and transplant (n = 6, 32%). The majority reported heavy menstrual bleeding (n = 12, 86% dialysis; n = 46, 94% nondialysis CKD; n = 14, 100% transplant). Less than half of participants were consistently able to afford period products. Condoms were the most common contraceptive reported. Most participants reported no contraceptive use (n = 10, 50% dialysis; n = 37, 63% nondialysis CKD; n = 7, 37% transplant), primarily because of \"fear\". Interviews (n = 6) revealed a perception of a relationship between kidney function and menstrual health, concerns about contraceptive use, and a desire for greater multidisciplinary care to improve kidney and reproductive health.
UNASSIGNED: Self-reported outcomes, need for internet access and a device.
UNASSIGNED: Abnormal menstruation and period poverty (ie, inability to afford period products and the socioeconomic consequences of menstruation) were common, and contraceptive use was low among female individuals with CKD, highlighting an important gap in the sex-specific care of this population.
UNASSIGNED: Chronic kidney disease (CKD) in female individuals is accompanied by menstrual disorders and low contraceptive use. However, most data are limited to the dialysis and transplant populations. Therefore, this mixed-methods study aimed to describe self-assessed menstruation and contraceptive use across all stages of CKD. People aged 18-50 years with a uterus and CKD diagnosis were invited to participate in an online survey shared internationally as well as an optional telephone interview. Abnormal menstruation and period poverty (ie, inability to afford period products and the socioeconomic consequences of menstruation) were common, and contraceptive use was low among female individuals with CKD, highlighting an important gap in the sex-specific care of this population.
