Hormonal contraceptives (HCs) are widely used and generally well tolerated; however, their neuroendocrinological effects remain underappreciated in clinical decision-making. Beyond ovulation suppression, HCs influence brain function by modulating key neurotransmitters such as GABA, serotonin, and dopamine, as well as neurosteroids like allopregnanolone and β-endorphin. These interactions help explain why some users experience mood swings, anxiety, or changes in sexual desire, while others report improvements in well-being. In this narrative review, we explore how different estrogenic and progestin components affect central pathways involved in emotional regulation and cognition. Evidence suggests that estradiol or estetrol-based formulations combined with anti-androgenic progestins like drospirenone or nomegestrol acetate may offer a more favourable neuroendocrine profile, particularly in women with a history of mood disorders or hormonal sensitivity. Understanding these neuroendocrine mechanisms may support more personalized contraceptive choices, particularly in women with mood disorders and hormonal vulnerability. Full article

Infertility is a complex and common problem in reproductive medicine consultations. Three factors must be examined during the preconception phase: breeding management, the fertility of the bitch, and the fertility of the stud dog. Among these factors, improper breeding management remains the main cause of reproductive failure, with accurate recognition of ovulation being crucial for successful mating. Artificial insemination allows for a thorough evaluation of semen quality compared to natural mating. In addition, genetic selection, nutritional factors, and reproductive health management can either impair or improve the fertility of females and males. Idiopathic infertility can occur in bitches, but it is important to rule out other possible causes first. In bitches with irregular estrus cycles, ovarian dysfunction and endocrine imbalances should be investigated. In bitches with regular cycles, uterine disorders such as cystic endometrial hyperplasia, endometritis or congenital anomalies may be the cause. Both mating-related and chronic endometritis are recognized as contributing factors to infertility. Infectious agents, particularly Brucella spp. and Mycoplasma spp., should also be evaluated, although interpretation of Mycoplasma test results requires caution. In males presenting with poor semen quality, potential causes include infectious diseases (with brucellosis always requiring exclusion), hormonal imbalances, and the impact of exogenous treatments. The article underscores the critical role of comprehensive diagnostic protocols, proactive health surveillance, and data-driven breeding strategies in systematically addressing this multifaceted challenge.

Polycystic ovary syndrome (PCOS) is an endocrine disorder prevalent in women of reproductive age, often requiring complex pharmacological management. The heterogeneity of the syndrome and the use of on- and off-label therapeutic agents—ranging from insulin sensitizers and ovulation inducers to oral contraceptives and herbal supplements—pose significant challenges, including adverse effects, drug interactions, and poor adherence. This narrative review explores the role of pharmacists in identifying and mitigating drug-related problems (DRPs) associated with PCOS therapy. Through thematic synthesis of the current literature, the study highlights common DRPs such as suboptimal drug selection, inappropriate dosing, prolonged therapy duration, and treatment-related safety concerns. It underscores the value of pharmacists’ interventions in enhancing medication adherence, optimizing therapeutic regimens, providing patient education, and monitoring adverse events. A structured, patient-level pharmaceutical care model is proposed, emphasizing personalized assessment, interdisciplinary collaboration, and continuous follow-up. The integration of clinical pharmacists into PCOS care teams has the potential to improve treatment effectiveness, patient satisfaction, and long-term health outcomes. Pharmacists’ contributions are especially critical given the widespread use of off-label therapies and supplements with variable evidence of benefit. Tailored pharmaceutical care can thus bridge the existing gaps in PCOS management and enhance the quality of life for the affected individuals. Full article

The success of in vitro fertilization (IVF) and female reproductive capacity are significantly determined by oocyte quality. Increasing data highlights the significance of oxidative stress—a state of imbalance between reactive oxygen species (ROS) and antioxidant defenses—in regulating oocyte competence. Normal folliculogenesis and ovulation rely on optimal ROS levels; excessive oxidative stress (OS) can lead to DNA fragmentation, undermine meiotic spindle integrity, and trigger apoptosis in cumulus and granulosa cells. Molecular insults impair nuclear and cytoplasmic maturation, thereby impacting fertilization potential and embryonic development. Individuals with polycystic ovarian syndrome (PCOS), endometriosis, advanced maternal age, and metabolic disorders—conditions associated with suboptimal IVF outcomes—frequently exhibit redox imbalance. This narrative review examines significant oxidative markers in the follicular environment, exploring the molecular processes linking OS to diminished oocyte quality and discussing therapy techniques aimed at mitigating oxidative damage. Maintaining redox homeostasis in the ovarian milieu appears to be an effective strategy for enhancing oocyte competence and optimizing outcomes in assisted reproduction. Full article

Endometriosis (EMS) is a long-term inflammatory disease. It represents one of the most prevalent gynecological conditions, impacting an estimated 5% of reproductive women. Therefore, endometriosis contributes to substantial worldwide health challenges and healthcare costs. In EMS disease, endometrial glandular and stromal tissues are abnormally located outside the uterus. Similarly to the natural endometrium, these tissues grow and proliferate in response to estrogen-dependent signals. The pain and limited effectiveness of treatments are often linked to the inflammatory reaction triggered by EMS-associated ectopic tissue. This is especially amplified during the peaks of estrogen release that occur as the menstrual cycle transitions from the proliferative phase to ovulation. Maintaining the integrity of the mucosal lining, defending against pathogenic insults, and controlling physiological processes are all made possible by a healthy, balanced state of gut biomass. Additionally, numerous intestinal bacteria have been discovered to possess estrogen-metabolizing enzymes, which affect the estrobolome and, consequently, influence estrogen-related disorders. Therefore, there is increasing interest in understanding the role of microbiota and the estrobolome in endometriosis pathogenesis. This review will focus on the role of microbiota and the impact of estrobolome alterations in endometriosis pathogenesis. Full article

Infertility affects 17.5% of couples worldwide, and is notably caused in females by ovarian disorders that impact follicle development and oocyte maturation. Polycystic ovary syndrome (PCOS), affecting 8 to 13% of women of reproductive age, is a leading cause of anovulation and is characterized by arrested antral follicle development before the preovulatory stage. Reproductive issues of PCOS are often exacerbated in overweight or obese women. Obesity, which is increasingly prevalent worldwide, is also associated with anovulation, primarily due to defects in oocyte quality. Oocyte quality and competence depend on the proper activity of granulosa cells (GCs), which surround and support the oocyte. GCs produce key factors, such as 17β-estradiol, which regulate follicle growth and oocyte maturation. They also provide essential metabolic support for oocyte maturation and play a critical role in ovulation and fertilization. This review outlines the physiological role of GCs in follicle growth and maturation and explores recent advancements in understanding GCs’ molecular and physiological dysfunctions that contribute to infertility in PCOS and obesity. Improved knowledge of the endocrine mechanisms underlying follicular abnormalities in these conditions could help to predict oocyte competence and enhance assisted reproduction outcomes.

Background: Polycystic ovary syndrome (PCOS) is an endocrine disorder prevalent in women of reproductive age. Treatment or management of this syndrome includes several pharmacological and non-pharmacological treatment approaches for different manifestations of the disease that vary with the patient’s age, symptoms, requirements, and geographical location. Objective: This systematic review aims to conduct a comprehensive and evidence-based analysis of the various available treatment options and identify knowledge gaps in PCOS management in India. Methods: A comprehensive search was conducted in PubMed, Scopus, and Embase databases from January 2010 till February 2024. We included randomized control trials (RCTs) using any pharmacological drugs (e.g., insulin sensitizers, anti-androgens, anti-obesity drugs, oral contraceptive pills, ovulation induction drugs, etc.) or non-pharmacological intervention (e.g., yoga, diet, herbal supplements, etc.) with Indian PCOS patients for improving common manifestations of PCOS and written in the English language. Studies were screened by two authors independently in a two-level process. Data extraction was also performed by two authors. Risk of bias was performed using the RoB 2 Tool. Subgroup analysis and meta-analysis were performed using the RevMan tool. Results: Thirty RCTs on pharmacological and eight on non-pharmacological interventions were included in the study. However, all the RCTs were so heterogeneous in terms of intervention used, subject recruited, and outcomes measured that meta-analysis was possible for only three subgroups (metformin vs. inositol, metformin vs. metformin+ inositol, and letrozole vs. clomiphene citrate), with only two or three studies per analysis. Most studies were single-centric and small-sized and had a high risk of bias, limiting their generalizability. Conclusions: This systematic review synthesized existing research and evaluated the effectiveness and safety of existing treatments. Limitations and gaps in the current research were identified, which may inform future research for better understanding and management of PCOS in the Indian context. Full article

Background: Polycystic ovary syndrome (PCOS) is a common female endocrine disorder characterized by hyperandrogenism, ovulatory dysfunction, and polycystic ovarian morphology. While canonical androgens like testosterone (T) and dihydrotestosterone (DHT) are well studied in PCOS pathophysiology, the role of 11-ketotestosterone (11KT) remains unclear. This study investigates the differential effects of these androgens on folliculogenesis, ovulation, and steroidogenesis using in vivo and in vitro models. Methods: Four-week-old female C57BL/6 mice received T, DHT, or 11KT for six weeks. The assessments included body weight, estrous cyclicity, serum hormone profiles, ovarian histology, and follicle classification. In parallel, large preantral follicles were cultured with each androgen to evaluate follicle growth, antrum formation, and ovulation capacity. Androgen receptor (AR) signaling and steroidogenic function were analyzed using western blotting, RT-qPCR, and luciferase reporter assays. Results: The DHT-treated mice exhibited increased weight gain, whereas 11KT-treated mice showed reduced weight gain. T and DHT disrupted the estrous cycle, while 11KT prolonged diestrus. All androgen treatments led to ovarian morphological changes, including follicular arrest and cystic features. In vitro, all androgens enhanced follicle growth, but only T and DHT inhibited ovulation. The AR expression was elevated across all androgen-treated groups, but only DHT significantly activated AR and CYP19A1 promoters. Conclusions: 11KT induces a distinct and milder PCOS-like phenotype compared to classical androgens, promoting follicle growth with minimal impact on ovulation or steroidogenic disruption. These findings underscore the heterogeneity of PCOS and suggest that different androgen profiles may drive diverse clinical phenotypes. By elucidating the distinct roles of different androgens, this may lead to better stratification of PCOS phenotypes based on predominant androgen types for more precise diagnosis and individualized management.

Background/Objectives: Vitamin D deficiency is common in women with polycystic ovary syndrome (PCOS) and may be associated with metabolic and endocrine disorders as well as ovulatory dysfunction. Vitamin D supplementation may improve ovarian dysfunction and follicular development by effecting gene expression. The aim of the present study was to investigate the effects of vitamin D supplementation in women with PCOS through a prospective, randomized, two-phase, parallel design, placebo-controlled trial. Methods: We assessed the impact on ovarian morphology, cycle length, and ovulatory dysfunction. Transvaginal ultrasonography (TVUS) examinations and clinical laboratory assessments were conducted at the baseline, and again after 12 and 24 weeks. The participants received vitamin D (30,000 IU/week) or a placebo (without concurrent metformin use) for 12 weeks, supplemented with calcium, followed by an additional 12 weeks of vitamin D treatment. Results: The treatment resulted in improvements in ovarian morphology and regularity of menstrual cycles in more than half of the patients. Additionally, vitamin D3 was associated with a significant increase in the ovulation rate. A statistically significant reduction in mean testosterone levels was observed in the subgroup of patients with an LH/FSH ratio greater than 2. Conclusions: Our results suggest that vitamin D3 treatment could function as either a standalone or an adjunctive therapy in the management of PCOS. Full article

Background/Objectives: Polycystic ovarian syndrome (PCOS) is a complex endocrine disorder affecting up to 15% of reproductive-age women, characterized by hyperandrogenism, chronic oligo-ovulation, and metabolic dysfunction. This study aims to evaluate serum sortilin levels in women with PCOS for the first time and investigate their potential associations with metabolic and hormonal alterations. Material and Methods: Eighty PCOS patients and 80 healthy controls were included; serum sortilin levels were measured using ELISA kits, with documented intra-assay and inter-assay variations below 6% and 8%, respectively, ensuring high specificity and sensitivity. Results: Serum sortilin levels were significantly elevated in PCOS patients (69.51 ± 27.75 pg/mL) versus controls (48.60 ± 21.20 pg/mL) (p < 0.001). PCOS patients exhibited higher mean HOMA-IR, free androgen index values, serum glucose, insulin, triglycerides, high-sensitivity C-reactive protein, luteinizing hormone, total testosterone, and DHEA-S levels, alongside reduced high-density lipoprotein cholesterol and sex hormone-binding globulin levels (all, p < 0.05). Notably, inverse correlations were observed between sortilin and low-density lipoprotein cholesterol levels in both groups (p = 0.028 and 0.033). Conclusions: This pioneering study indicates that serum sortilin may be implicated in PCOS pathogenesis and serves as a potential biomarker for metabolic dysfunction in PCOS. Larger, diverse studies with longitudinal designs are needed for further validation. Full article

Introduction: Excessive body weight, particularly the abdominal distribution of adipose tissue, has remained an important public health concern for years. Objectives: The study aimed to assess the prevalence of general overweight status and obesity, as well as abdominal overweight status and obesity in the adult Polish population. Material and methods: The results are based on the analysis of anthropometric data of 3735 people aged 19 and over who were surveyed under the 2016–2020 National Health Program. Results: Excessive body weight (BMI > 25 kg/m²) was reported in 56.6% of the respondents. Abdominal overweight was found in 20.8% of respondents and abdominal obesity in 31.7% of the respondents. Abdominal obesity was more common in women than in men (44.3% vs. 18.0%, p < 0.001). Over half of women over 55 (approx. 60%) had abdominal obesity. The odds of becoming overweight/obese as measured by the BMI depended on the age and sex of the respondents. It was confirmed that men were over 28% more likely to develop such a condition than women (OR = 1.288, p < 0.001). The odds increased with age (OR = 1.029, p < 0.001). The type of person with obesity/found to be overweight in Polish population was most often a rural resident, aged 65.0–74.9, assessing their financial situation as average, being married/in a partnership, and not declaring the occurrence of cardiovascular diseases. The person with an overweight status had secondary education, and the person with obesity had primary/lower secondary/vocational education. Conclusions: Being overweight and having obesity, both general and abdominal, are still a major epidemiological problem in Poland. The results obtained in this study suggest that the prevalence of being overweight and having obesity has decreased over the last 10 years, though this assumption requires further investigation. Rural residents with lower education should be covered by educational activities adapted to their needs and possibilities, considering that obesity in young women, especially when having abdominal obesity, may be associated with an increased risk of infertility caused by ovulation disorders. Further research and educational activities are necessary. Excessive body weight affected almost 42% of the women from the youngest age group, and abdominal obesity was found in 21% of them.

Female fertility and reproductive system disorders are influenced by a complex interplay of biological, physiological, and environmental factors. Minerals have emerged as crucial yet often overlooked elements that impact fertility and the prevalence of reproductive system disorders. Background/Objectives: This review aims to provide a comprehensive overview of the multifaceted role of minerals in female fertility, focusing on key areas such as oocyte quality, ovulation, embryo development, oxidative stress, miscarriage, hormonal regulation, environmental exposure, and in-vitro fertilization (IVF) outcomes. Methods: A systematic review was conducted, focusing on randomized controlled trials (RCTs), prospective cohort studies, case-control studies, nested case-control, and observational studies examining mineral supplementation and nutrition in women planning pregnancy or utilizing assisted reproduction technologies (ARTs). Relevant literature was sourced from multiple electronic databases, including PubMed, Scopus, Google Scholar, Web of Science, and the Cochrane Library, using keywords related to minerals and female fertility. The quality of studies was assessed using the Newcastle–Ottawa Scale (NCO) for non-randomized studies and the Risk of Bias (RoB) tool for RCTs. This systematic review has been registered on PROSPERO (registration number is CDR 42024547656). Results: From an initial pool of 20,830 records, 39 articles met the inclusion criteria and were analyzed. The studies addressed various reproductive outcomes influenced by minerals: embryo development, oocyte quality, oxidative stress, miscarriage, hormonal regulation, IVF outcomes, environmental exposure, and minerals as biomarkers. The analysis revealed that minerals like selenium, zinc, and copper are essential for maintaining reproductive health, while exposure to toxic metals such as cadmium and lead is detrimental. Conclusions: This review highlights the crucial role of both mineral supplementation and serum mineral status in female fertility. The findings provide key insights for clinicians to improve reproductive health through targeted mineral intake and monitoring. Further research is needed to refine guidelines for supplementation and serum levels in women with fertility issues. Full article

Background: The reproductive age of women is particularly vulnerable to the effects of polycystic ovarian syndrome (PCOS). High levels of testosterone and other male hormones are frequent contributors to PCOS. It is believed that miscarriages and ovulation problems are majorly caused by PCOS. A recent study found that 31.3% of Asian women have been afflicted with PCOS. Healing women with life-threatening disorders associated with PCOS requires more research. In prior research, methods have involved autonomously classified PCOS using a number of different machine learning techniques. ML-based approaches involve hand-crafted feature extraction and suffer from low performance issues, which cannot be ignored for the accurate prediction and identification of PCOS. Objective: Hence, predicting PCOS using cutting-edge deep learning methods for automated feature engineering with better performance is the prime focus of this study. Methods: The proposed method suggests three lightweight (LSTM-based, CNN-based, and CNN-LSTM-based) deep learning models, incorporating SMOTE for dataset balancing to obtain a valid performance. Results: The proposed three models tend to offer an accuracy of 92.04%, 96.59%, and 94.31%, an ROC-AUC of 92.0%, 96.6%, and 94.3%, the number of parameters of 6689, 297, and 13285, and a training time of 67.27 s, 10.02 s, and 18.51 s, respectively. In addition, the DeLong test is also performed to compare AUCs to assess the statistical significance of all three models. Among all three models, the SMOTE + CNN models performs better in terms of accuracy, precision, recall, AUC, number of parameters, training time, DeLong’s p-value over the other. Conclusions: Moreover, a performance comparison is also carried out with other state-of-the-art PCOS detection studies and methods, which validates the better performance of the proposed model. Thus, the proposed model provides the greatest performance, which can lead to a reduction in the number of failed pregnancies and help in finding PCOS in the early stages. Full article

Tailgut cysts are rare lesions which are found in the rectorectal space. They develop in the final section of the intestine from which the rectum and anus extend and vary from being asymptomatic to symptomatic due to pressure on organs or nerves. Tailgut cysts are more common in females, usually between 30 and 60 years of age. They are thought to be benign, with variable malignancy risks. Surgical excision followed by histological examination is the gold standard of treatment, but access and approach to tailgut cysts depend on the location and morphology of the lesion. We present two symptomatic cases of this very rare pathology. In both cases, the cyst and coccyx bone were successfully excised using different approaches. The first patient was a 40-year-old woman with a large cyst which caused morning tenesmus, urinary outflow disorders and painful ovulation. Due to the cyst size, laparotomy was performed, and a combined approach was used. The second patient is a 36-year-old woman with co-existing endometriosis and a cyst causing pain in the sacral spine, constipation and tenesmus. The tumor was excised using a Kraske approach, and due to the infiltration of the coccyx bone it was removed using an osteotome. In this patient, perforation of the cyst was also observed. Both patients completed follow-ups involving regular surgical check-ups and MRI scans. Descriptions of different symptoms and surgical approaches make our study an important source of knowledge for diagnosing and treating these very rare tumors. Full article
