Predictors of partnership and sexual satisfaction and dyadic effects in couples affected by endometriosis and infertility.

Endometriosis and infertility are associated with impaired partnership and sexuality of the patients, but also of their male partners. Also, endometriosis is one of the most common causes of infertility, resulting in a large overlap of both pathologies. The aim of this study was to determine the association of different predictors of partnership and sexual satisfaction and dyadic effects in couples with endometriosis and infertility. A cross-sectional study was conducted with n = 62 women with endometriosis and n = 46 partners, including a total of n = 44 couples, some of whom were affected by infertility. The questionnaire included items on partnership, sexuality, depression, social support, and desire for a child. Multiple linear regression and the actor-partner-interdependence-model were used for analysis. Significant dyadic effects only occurred in couples with both endometriosis and infertility. Depression showed a significant negative actor effect in men for partnership satisfaction and a negative actor and partner effect in women for sexuality satisfaction (p < .05). For women, social support showed a significant positive actor effect for partnership satisfaction (p < .05), age showed a significant actor and partner effect for sexuality satisfaction (p < .05). The results show a significant association of endometriosis and infertility with partnership and sexuality satisfaction. Infertility could be a decisive factor. However, the large overlapping of both endometriosis und infertility in many couples support the importance of further studies to differentiate between the both effects.

Use of equine embryo -derived mesenchymal stromal cells and their extracellular vesicles as a treatment for persistent breeding-induced endometritis in susceptible mares

Persistent breeding induced endometritis (PBIE) is a significant cause of infertility in mares. The development of a safe, universal, readily available therapeutic to manage PBIE and facilitate an optimal uterine environment for embryo development may improve pregnancy rates in susceptible mares. Mesenchymal stromal cells (MSCs) are being used increasingly as a therapeutic mediator for inflammatory conditions such as endometritis, and early gestational tissue provides a unique source of multipotent stem cells for creating MSCs. Extracellular vesicles (EVs) are mediators of cell communication produced by many different cell types. This study utilized embryo-derived mesenchymal stromal cells (EDMSCs) and their EVs as a potential therapeutic modality for PBIE in two groups: a) PBIE-susceptible mares challenged with pooled dead sperm (n=5); and b) client-owned mares diagnosed as susceptible to PBIE (n=37 mares and 40 estrous cycles). Mares pre-treated with intrauterine EDMSCs or their EVs resulted in a significant reduction in the accumulation of intrauterine fluid post-breeding. Nine of 19 (47 %) mares treated with EDMSCs prior to natural breeding and 13 of 20 (65 %) mares treated with EDMSC derived EVs were pregnant after the first cycle and 12 of 18 (67 %) mares treated with EDMSCs, and 15 of 19 (79 %) mares treated with EVs conceived by the end of the breeding season. These preliminary clinical studies are the first reports of the use of EDMSCs or their EVs as a potential intrauterine therapy for the management of PBIE susceptible mares.

The Territorial Distribution of Incidence with Urogenital Chlamydia, Gonorrhea, and their Associated Complications in the Russian Federation

Relevance. Urogenital chlamydia is one of the most common sexually transmitted infections. Chlamydia often presents with minimal or no symptoms. However, it can be a major cause of pelvic inflammatory disease (PID), infertility, and ectopic pregnancy in women, as well as epididymitis, orchitis, and infertility in men. Aim. To study the territorial patterns of incidence of urogenital chlamydia, gonorrhea, and their associated complications in the Russian Federation in 2011 to 2019. Materials and methods. Official statistics on the incidence of urogenital chlamydia, gonorrhea, PID, female and male infertility in the Russian Federation were analyzed. Statistical analysis, graphing, table creation, data visualization, and research results analysis were conducted using Microsoft Excel 2010 and IBM SPSS Statistics 22 software. GIS mapping was performed using the GIS «Axioma». Results and discussion. From 2011 to 2019, the Russian Federation observed a decrease in the incidence of urogenital chlamydia, gonorrhea, and PID, while there was an increase in the incidence of male and female infertility. The geographical distribution remained stable, with areas characterized by consistently low and high incidence rates. A correlation was found between the incidence of urogenital chlamydia, gonorrhea, and their complications. The association between gonorrhea and PID was found to be more significant than the association between chlamydia and PID, possibly due to the higher risk of complications associated with gonorrhea. However, no correlation was found between gonorrhea and infertility, possibly because this complication manifests with a time delay and has multifactorial causes. Conclusions. Based on the presented data, it can be concluded that the incidence of urogenital chlamydia and gonorrhea affects the frequency of male and female infertility. Therefore, the implementation of screening examinations for sexually active individuals of reproductive age using appropriate laboratory diagnostic methods, along with the development of preventive measures for sexually transmitted infections, including urogenital chlamydia, is justified and should be widely practiced.

Infertility in POMC-deficient mice

The pro-opiomelanocortin (POMC) gene is expressed in the hypothalamus and pituitary and its product is cleaved into several peptides including the melanocyte stimulating hormones (α, β, or γ-MSH), adrenocorticotropic hormone (ACTH), and beta-endorphin. Alpha-MSH is involved in regulating appetite, sexual behavior, and melanin, while ACTH regulates secretion of glucocorticoids from the adrenal cortex. Humans who have a POMC mutation either produce an abnormally short version of POMC or are missing the protein completely and therefore lack these hormones. This has biological consequences including red hair and fair skin, early-onset obesity (due to severe hyperphagia), and potentially hypothyroidism, hypogonadism, and infertility. Many of these same effects are seen with mice containing this deficiency. We are interested in studying infertility through a mouse model of hypothalamic-specific POMC-deficiency. These mice also experience early-onset obesity and infertility. Estradiol is a key reproductive hormone that is essential for fertility. POMC deficiency may lead to hypogonadism, which can cause low levels of estrogen so we hypothesize that POMC-deficient mice have reduced estrogen levels, which may contribute to their infertility. To test this hypothesis, we will measure estrogen levels in POMC-deficient mice at different stages of the estrus cycle using an estradiol ELISA kit. We expect the POMC-deficient mice to have lower estrogen levels than control mice. We also plan to use liquid chromatography mass spectrometry (LC-MS) to measure estrogen levels. Before collecting the blood samples, vaginal cell samples are obtained and viewed under a microscope to analyze the ratio of cells and determine which stage the females were in—proestrus, estrus, metestrus, or diestrus. Blood samples are then collected into 1.5 mL microcentrifuge tubes with 10 microliters of 0.5 M EDTA to prevent blood clotting. After blood is collected, it is centrifuged at 2,000 g for 20 minutes at 4 degrees Celsius. The plasma is then stored at -80 degrees Celsius until analysis. Based on preliminary results we expect the POMC deficient mice to have reduced estrogen and/or altered levels throughout the cycle. So far, our results have indicated that POMC-deficient female mice have abnormal estrus cycles and also reduced uterine weights. The conclusions from this study will help us understand more about the causes of infertility in POMC-deficient mice, which may also lead to greater understanding on how to treat humans with infertility due to a POMC mutation.

Fungal-bacteria interactions provide shelter for bacteria in Caesarean section scar diverticulum.

Caesarean section scar diverticulum (CSD) is a significant cause of infertility among women who have previously had a Caesarean section, primarily due to persistent inflammatory exudation associated with this condition. Even though abnormal bacterial composition is identified as a critical factor leading to this chronic inflammation, clinical data suggest that a long-term cure is often unattainable with antibiotic treatment alone. In our study, we employed metagenomic analysis and mass spectrometry techniques to investigate the fungal composition in CSD and its interaction with bacteria. We discovered that local fungal abnormalities in CSD can disrupt the stability of the bacterial population and the entire microbial community by altering bacterial abundance via specific metabolites. For instance, Lachnellula suecica reduces the abundance of several Lactobacillus spp., such as Lactobacillus jensenii, by diminishing the production of metabolites like Goyaglycoside A and Janthitrem E. Concurrently, Clavispora lusitaniae and Ophiocordyceps australis can synergistically impact the abundance of Lactobacillus spp. by modulating metabolite abundance. Our findings underscore that abnormal fungal composition and activity are key drivers of local bacterial dysbiosis in CSD.

Patient satisfaction with nursing care in infertility patients: A questionnaire survey.

Infertility remains a persistent global reproductive health challenge, with causative factors encompassing abnormalities in both the male and female reproductive systems. Typically, female partners seek initial consultations for infertility concerns, often within the context of routine annual well-woman check-ups. Nurses providing preventive care play a crucial role, conducting initial diagnostic assessments, and addressing certain causes of infertility. Patient satisfaction serves as a vital indicator of care quality. Identifying factors contributing to patient satisfaction with nursing services is crucial, yet research in this area has been limited. This study aimed to compare infertility patients' assessments of nurse quality and satisfaction with hospital services. The findings could offer valuable insights for healthcare providers, hospitals, and policymakers, guiding improvements in nursing care delivery and enhancing patient satisfaction in China's infertility treatment sector. By understanding patients' perspectives and experiences, healthcare providers can make necessary adjustments to improve care quality and patient outcomes. The sample included 1200 patients, and data collection utilized a self-assessment questionnaire, with percentages employed for analysis. Nurses are integral to caring for infertility patients during visits and conducting research to advance fertility care practices.

Apoptotic-Related MiRNAs Correlated with Functional and Flow Cytometric Parameters in Asthenozoospermic Holstein Bulls After Freeze-Thaw Process.

Many cellular processes in spermatozoa, including apoptosis and motility, are regulated by miRNA. Different miRNAs and molecular pathways are involved in asthenozoospermia (AS) conditions, which are thought to be one of the causes of infertility with reduced sperm motility. Thirty-two semen samples from four Holstein bulls with normozoospermia (NS), total motility ≥ 70%, and progressive motility ≥ 60%, and 32 semen samples from four bulls with AS, total motility ≤ 40%, and progressive motility ≤ 32% were used to investigate the function of apoptosis-related miRNAs in the AS group. Samples were then aspirated into a 0.5 mL straw after dilution with a Tris-egg yolk extender and frozen at -196°C. After freezing, semen samples were thawed for 2 weeks at 37°C and sperm kinematic parameters, plasma membrane integrity, acrosome integrity, DNA fragmentation, apoptosis status, and expression of apoptosis-related miRNAs (miR-2114, miR-296-3p, miR-455-3p, and miR345-3p) were evaluated. Our results showed that the functional and flow cytometric parameters of the NS group were significantly better than those of the AS group. In the NS group, miR-455-3pp and miR-2412 were upregulated, while miR-345-3p was downregulated compared with the AS group. In the AS group, miR-296-39, miR-2412, and miR-345-3p levels were strongly correlated with membrane integrity, DNA fragmentation, and apoptosis status. The findings demonstrated that the selected miRNAs based on bioinformatic analysis in AS and NS samples had a substantial association with functional and flow cytometry indicators and may be involved in regulating apoptosis and motility in AS samples.

Individual disruption of 12 testis-enriched genes via the CRISPR/Cas9 system does not affect the fertility of male mice

More than 1200 genes have been shown in the database to be expressed predominantly in the mouse testes. Advances in genome editing technologies such as the CRISPR/Cas9 system have made it possible to create genetically engineered mice more rapidly and efficiently than with conventional methods, which can be utilized to screen genes essential for male fertility by knocking out testis-enriched genes. Finding such genes related to male fertility would not only help us understand the etiology of human infertility but also lead to the development of male contraceptives. In this study, we generated knockout mice for 12 genes (Acrv1, Adgrf3, Atp8b5, Cfap90, Cfap276, Fbxw5, Gm17266, Lrrd1, Mroh7, Nemp1, Spata45, and Trim36) that are expressed predominantly in the testis and examined the appearance and histological morphology of testes, sperm motility, and male fertility. Mating tests revealed that none of these genes is essential for male fertility at least individually. Notably, knockout mice for Gm17266 showed smaller testis size than the wild-type but did not exhibit reduced male fertility. Since 12 genes were not individually essential for male fertilization, it is unlikely that these genes could be the cause of infertility or contraceptive targets. It is better to focus on other essential genes because complementary genes to these 12 genes may exist.

Zinner syndrome in a case of male infertility: a case report

Zinner syndrome is a rare congenital malformation formed by the developmental anomaly of distal portion of the wolffian duct. It is an unusual cause of infertility and dysuria among young males. It is associated with ipsilateral renal agenesis, seminal vesical cyst, and ejaculatory duct obstruction. We herein report a rare case of a Zinner syndrome, in a patient of primary infertility. He also presented with complaints of chronic pelvic pain and dysuria. Any young patients of male infertility or unspecified pelvic complaints should be evaluated for Zinner syndrome and surgical intervention is the mainstay treatment for symptomatic patients.

Correlation of Anti-Mullerian Hormone with Antral Follicle Count among South Indian Infertile Women in a Tertiary Care Center

Abstract Context: Diminished ovarian reserve (DOR) is one of the important causes of infertility and its incidence is increasing even in younger age groups with no risk factors. Ovarian reserve needs to be evaluated in an infertile couple as the fecundity or response to ovarian stimulation is less in women with DOR. Anti-Mullerian hormone (AMH) and antral follicle count (AFC) are markers of ovarian reserve with the highest sensitivity. Aims: The aim of this study was to assess the ovarian reserve among infertile women through AMH and AFC, to find if there is a correlation between AMH and AFC, and to see if there is a correlation between AMH and AFC with age. Settings and Design: This study was conducted at the Department of OBG, JSS Hospital, JSS AHER, Mysore. This was a cross-sectional study. Materials and Methods: The study included 141 infertile women aged 19–45 years. Serum AMH was measured using chemiluminescent immunoassay irrespective of the day of the menstrual cycle and AFC was measured on 2nd or 3rd day of the menstrual cycle by transvaginal ultrasound. Statistical Analysis Used: Student’s-t-test, Chi-square test, and Pearson’s correlation were used for analysis. Results: Mean AMH and AFC of the subjects were 4.52 ± 4.16 ng/ml and 17.08 ± 12.54, respectively. A significant positive correlation was noted between AMH and AFC (r = 0.663, P &lt; 0.01) and there was a significant negative correlation between age as compared with AFC (r = −0.349, P &lt; 0.01) and AMH (r = −0.244, P &lt; 0.01). Conclusion: AFC and AMH showed a significant negative correlation with age. AFC had a strong positive correlation with serum AMH.

Endometriosis in infertile women: an observational and comparative study of quality of life, anxiety, and depression

BackgroundA women’s chances of getting pregnant decreases in cases of infertility, which may have several clinical etiologies. The prevalence of infertility is estimated as 10–15% worldwide. One of the causes of infertility is endometriosis, defined as the presence of an endometrial gland and/or stroma outside the uterus, inducing a chronic inflammatory reaction. Thus, infertility and endometriosis are diagnoses that significantly affect women’s mental health. This study accessed and compared the levels of depression, anxiety, and quality of life in infertile women with and without endometriosis.Methodswas an observational and cross-sectional study which included 201 infertile women, 81 of whom were also diagnosed with endometriosis. The STROBE Guidelines was used. The data were collected using validated scales: Hamilton D Questionnaire, Beck Depression Inventory, and Fertility Quality of Life Questionnaire; The data were collected at the Ideia Fertil Institute (Santo Andre, Brazil), between February 28 and June 8, 2019.Resultsthe infertile women with endometriosis reported higher presence of depressive symptoms and a lower quality of life compared to women with infertility only. Similar presence of anxiety symptoms was observed regardless of being diagnosed with endometriosis. Women with infertility and endometriosis presented lower levels in quality-of-life domains when compared to women with infertility only - Mind and Body (58.33 × 79.17, p < 0.001), Relational (75 × 81.25, p = 0.009), Social (66.67 × 77.08, p = 0.001), Emotional (50.62 × 67.43, p < 0.001).Conclusionthe findings indicate the need for increased psychosocial support care for women suffering from infertility and endometriosis to assist them in maintaining and managing their own mental health and achieving their reproductive goals.

Comparing GDF9 in mature follicles and clinical outcomes across different PCOS phenotype

BackgroundPolycystic ovary syndrome (PCOS) is main cause of anovulatory infertility in women with gestational age. There are currently four distinct phenotypes associated with individualized endocrinology and metabolism. Growth differentiation factor 9 (GDF9) is a candidate as potential biomarker for the assessment of oocyte competence. The effect on oocyte capacity has not been evaluated and analyzed in PCOS phenotypes. ObjectiveWe aimed to screen the expression levels of GDF9 in mature follicles of women with controlled ovarian hyperstimulation (COS) with different PCOS phenotypes. To determine the correlation between the expression level of GDF9 and oocyte development ability. MethodsIn Part 1, we conducted a retrospective study comparing the clinical outcomes and endocrine characteristics of patients with PCOS according to different subgroups (depending on the presence or absence of the main features of polycystic ovarian morphology (PCOM), hyperandrogenism (HA), and oligo-anovulation (OA)) and non-PCOS control group. We stratified PCOS as phenotype A (n = 29), phenotype B (n = 18) and phenotype D (n = 24). In Part 2, the expression of GDF9 in follicular fluid (FF) and cumulus cells (CCs) were detected by enzyme-linked immunosorbent assay (ELISA) and immunohistochemistry, respectively. ResultsIn Part 1, the baseline clinical, hormonal, and ultrasonographic characteristics of the study population were matched with the presence or absence of the cardinal features of each PCOS phenotypes showed a clear difference. Phenotypes A and D had statistically significant associations with blastocyst formation and clinical pregnancy compared with phenotypes B (p < 0.001). In Part 2, the levels of GDF9 in FF and CCs for phenotype A and B were significantly were higher than those of phenotype D (P = 0.019, P = 0.0015, respectively). Multivariate logistic regression analysis showed that GDF9 was an important independent predictor of blastocyst formation (P＜0.001). The blastocyst formation rate of phenotype A was higher than that of phenotype B and D (P＜0.001). Combining the results of the two parts, GDF9 appears to play a powerful role in the development of embryos into blastocysts. ConclusionsGDF9 expression varies with different PCOS phenotypes. Phenotype A had higher GDF9 levels and blastocyst formation ability.

Semen parameter enhancement after varicocelectomy: Insights into varicose vein diameter and BMI influence: A cross-sectional study.

Varicocele is a condition in which the veins in the spermatic cord become enlarged and twisted. Varicocele is widely recognized as the leading cause of male infertility due to its significant impact on reproductive health in men. The aim of this study was to investigate the relationship between the diameter of the varicose vein and the recovery rate of the spermogram after varicocelectomy. Also, the effect of body mass index (BMI) on sperm parameters after varicocelectomy. This descriptive and analytical cross-sectional study was conducted in Valiasr Hospital's urology clinic in Qaemshahr, Iran from August 2018 to August 2019 and involved 27 men with unilateral left varicocele who met the inclusion criteria for surgical repair. Before the operation, we recorded demographic information, the maximum diameter of varicose veins in the pampiniform plexus, and spermogram results. We repeated semen analysis 3 months after the operation and analyzed the data using Statistical Package for the Social Sciences version 21 software. Our findings showed that the diameter of the varicose vein before varicocelectomy was not significantly associated with the improvement of main semen parameters after the operation. Furthermore, our study suggested that a lower body mass index might contribute to a greater improvement in sperm motility, as individuals with lower BMI showed more significant improvement. There is a significant inverse relationship between BMI and sperm motility improvement after surgery. Patients with a lower BMI showed greater improvement in sperm motility.

Systematic Review of the roles of Inositol and Vitamin D in improving fertility among patients with Polycystic Ovary Syndrome.

Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder among reproductive-age women. As a leading cause of anovulatory infertility, it complicates fertility treatments, including in vitro fertilization. The widely accepted 2003 Rotterdam diagnostic criteria for PCOS include sub-phenotypes based on variations in androgen excess, ovulatory dysfunction, and polycystic ovarian morphology. In this systematic review, we examined the impacts of inositol and vitamin D on fertility in PCOS. Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines, we used relevant keywords to comprehensively search databases including PubMed, Google Scholar, and MDPI. From an initial pool of 345 articles, 10 met the inclusion criteria. The articles suggest that vitamin D and inositol, particularly myo-inositol and D-chiro-inositol, may represent therapeutic options for PCOS. Vitamin D influences ovarian follicular development, glucose regulation, and insulin sensitivity. When combined with metformin therapy, it is associated with improved menstrual regularity and ovulation. Inositol is crucial for cellular signaling, energy metabolism, glucose regulation, and fertility. This systematic review underscores the importance of investigating inositol and vitamin D within a PCOS management strategy, given the disorder's prevalence and impacts on fertility and metabolic health. Although these agents show promise, additional research could clarify their mechanisms of action and therapeutic benefits. This review emphasizes the need for exploration of effective treatments to improve the quality of life among individuals with PCOS. Inositol and vitamin D represent potential options, but more studies are required to elucidate their roles in the management of this condition.

Unlocking Fertility - with administration of Lekhaniya Mahakashaya in Pushpaghani Jataharini w.s.r. to PCOD

Children are a gift from the Lord; the fruit of the womb is a divine reward. Average Reproductive Age is 14-49 yrs. This age group have number of conditions related to menstrual cycle, such as Menorrhagia, Dysmenorrhea, Irregular menses, PCOD, endometriosis, etc. According to WHO - PCOD is a lifestyle disorder which is a common hormonal condition that affects women of reproductive age. It usually starts during adolescence, but symptoms may fluctuate over time. PCOD can cause hormonal imbalances, irregular periods, excess androgen levels and cysts in the ovaries, absence of menstruation, excessive hair growth (face, body, including back, belly and chest), acne, weight gain, hair loss, skin darkening (in neck and groin). Irregular periods, usually with a lack of ovulation, can lead infertility. PCOD is a leading cause of infertility. PCOD can lead to anovulation where ovaries stop releasing eggs. PCOD is a common condition that causes 70% of anovulation cases. PCOD causes the excessive production of androgens, which cause the follicles in your ovaries to remain small instead of maturing and growing as they have to prepare for ovulation. In Ayurveda on the basis of symptoms Pushpaghani Jataharini can be correlated with PCOD. PCOD is a chronic condition and cannot be cured. However, some symptoms can be improved through lifestyle changes and medications. In order to treat PCOD the changes in the life style and the administrations of Ausadhies like Lekhaniya Mahakashaya (Musta, Kustha, Haridra, Daruharidra, Vacha, Ativisha, Katurohini, Chitrak, Chirbilva).

Time, temperature and media: the three keys to improve the recovery of Campylobacter fetus subsp. venerealis from preputial bull samples

The isolation of Campylobacter fetus subsp. venerealis (Cfv) from clinical samples is the gold standard for confirming cases of bovine genital campylobacteriosis, an important cause of infertility in cattle and a potential public health concern. Furthermore, isolation is also necessary for the development of autologous vaccines, characterization of strains for antimicrobial susceptibility patterns, etc. Nevertheless, the sensitivity of culture methods is usually low, and there is no standardized protocol to maximize the recovery of Cfv from clinical samples. The aim of the current study is to design a protocol for the culture of Cfv from preputial samples by evaluating the combination of different transport, enrichment and culture media considering the impact of certain factors (time between collection and enrichment, temperature, and use of filters). The use of modified Lander’s transport medium and storing the sample for 24 h at 21 ± 2 °C led to the highest recovery of Cfv CFUs. In contrast, the storage of the samples during 24–48 h in PBS and Thomann rarely allowed the recovery of Cfv regardless of the temperature. The enrichment medium yielding the best results was Preston (significantly higher recovery than Brucella medium), while Cfv could not be isolated with Bolton. Regarding our diagnostic assay (using Lander as transport medium and Preston as enrichment medium), the best protocol in terms of maximizing Cfv recovery as well as limiting contaminations is to culture the samples in i) solid media Preston or Skirrow, and ii) using 0.65 μm filters and incubating plates at 37 °C in microaerophilic conditions.

An Ayurvedic perspective of Female Infertility - A Case Study

Infertility is an emerging health problem that has profound socioeconomic and health implication on both the individual and society. Unexplained Infertility is defined as the inability to conceive even after one year with routine investigations of infertility showing no abnormality; with overall incidence of 10-30%. Ayurveda assures normal pregnancy by proper maintenance of Garbha Samgraha Samagris and normalcy of mind. All the causes of female infertility come under the imbalance of Garbha Samgraha Samagri and Manasika factors. In this case report patient suffered from primary infertility since years, after allopathic consultation came for Ayurvedic treatment. From detailed history involvement of vitiated Vata, Agnimandhya and stressful mind was noticed. The line of treatment followed in this case was Virechana, Basti, Nasya, Vatanulomana, Garbhastapana Aushadhis and psychological assurance that favours conception in this couple.

Diagnosis of hyperprolactinemia in women: A Position Statement from the Brazilian Federation of Gynecology and Obstetrics Associations (Febrasgo) and the Brazilian Society of Endocrinology and Metabolism (SBEM).

Hyperprolactinemia is a frequent cause of menstrual irregularity, galactorrhea, hypogonadism, and infertility. The most common etiologies of hyperprolactinemia can be classified as physiological, pharmacological, and pathological. Among pathological conditions, it is essential to distinguish prolactinomas from other tumors and pituitary lesions presenting with hyperprolactinemia due to pituitary stalk disconnection. Proper investigation considering clinical data, laboratory tests, and, if necessary, imaging evaluation, is important to identify the correctcause of hyperprolactinemia and manage the patient properly. This position statement by the Brazilian Federation of Gynecology and Obstetrics Associations (Febrasgo) and Brazilian Societyof Endocrinology and Metabolism (SBEM) addresses the recommendations for measurement of serum prolactin levels and the investigations of symptomatic and asymptomatic hyperprolactinemia and medication-induced hyperprolactinemia in women.

Establishment and validation of a 5-factor diagnostic model for obstructive and non-obstructive azoospermia based on routine clinical parameters.

Azoospermia is a serious leading male-factor cause of infertility in couples of childbearing age. The two main azoospermia types, obstructive (OA) and non-obstructive (NOA) azoospermia, differ in their treatment approaches. Therefore, their clinical diagnosis is extremely important, requiring an accurate, efficient, and easy-to-use diagnostic model. This retrospective observational study included 707 patients with azoospermia treated between 2017 and 2021, 498 with OA, and 209 with NOA. Hematological and seminal plasma parameters, hormone levels, and testicular volume were used in logistic regression analysis to evaluate and compare their diagnostic performance, results showed that the optimal diagnostic model is constructed by five variables including semen volume, semen pH, seminal plasma neutral α-glucosidase activity, follicle-stimulating hormone in the serum, and testicular volume, compared with follicle-stimulating hormone-based and testicular volume-based models. The 5-factor diagnostic model had an accuracy of 90.4%, sensitivity of 96.4%, positive predictive value of 90.6%, negative predictive value of 89.8%, and area under the curve of 0.931, all higher than in the other two models. However, its specificity (76.1%) was slightly lower than in the other models. Meantime, the internal 5-fold cross-validation results indicated that the 5-factor diagnostic model had a good clinical application value. This study established an accurate, efficient, and relatively accessible 5-factor diagnostic model for OA and NOA, providing a reference for clinical decision-making when selecting an appropriate treatment.
