ENTPD3 is involved in various pathophysiological processes, including cellular adhesion, metabolism, activation, and migration. However, its specific function in the uterus remains unclear. This study aimed to investigate the expression pattern and localization of Entpd3 in the mouse uterus throughout the estrous cycle using immunohistochemistry (IHC), quantitative real-time PCR, and western blot analysis. The effect of sex steroid hormones on Entpd3 expression was also examined in ovariectomized (OVX) mice treated with 17β-estradiol (E2)/progesterone (P4) and estrogen receptor antagonist (Fulvestrant)/progesterone receptor antagonist (Mifepristone). Results demonstrated that elevated levels of Entpd3 mRNA and protein were noted during estrus and metestrus, with a decline in diestrus and proestrus. IHC revealed abundant ENTPD3 in the cytoplasm of glandular and luminal epithelial cells during estrus and metestrus. Additionally, treatment with E2 or P4 in OVX mice downregulated the expression of Entpd3 in the mouse uterus, which was rescued by Fulvestrant or Mifepristone. This study demonstrated that the expression of Entpd3 in the mouse uterus varied dynamically throughout the estrous cycle and was steroid-dependent, suggesting a potential role for Entpd3 in female mice's reproductive function.","PeriodicalId":20920,"journal":{"name":"Reproductive Sciences","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142682627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review provides an overview of neurotransmitter alterations during different menstrual cycle phases and their effects on physiology and psychology. During the follicular phase, rising estrogen levels increase serotonin synthesis, enhancing mood, cognition, and pain tolerance. Estrogen may also influence dopamine levels, promoting motivation and reward sensitivity. GABA, involved in anxiety regulation, may be modulated by estrogen, inducing relaxation. Ovulation involves fluctuating dopamine and serotonin levels, potentially affecting motivation and positive mood. In the luteal phase, rising estrogen and progesterone may reduce serotonin availability, contributing to mood dysregulation, while enhanced GABAergic neurotransmission promotes sedation. Menstruation is characterized by declining estrogen and progesterone, potentially leading to mood disturbances, fluctuating GABAergic and dopaminergic neurotransmitter systems, relaxation, fatigue, motivation, and pleasure variations. Understanding neurotransmitter alterations during the menstrual cycle unveils the neurobiological mechanisms behind menstrual-related symptoms and disorders, facilitating targeted interventions. Pharmacological approaches targeting neurotransmitter systems, nutritional interventions, and lifestyle modifications show promise in managing menstrual symptoms. Future research should focus on further understanding neurotransmitter dynamics, personalized medicine, unexplored neurotransmitter roles, and integrating psychosocial factors. This knowledge will enhance well-being and quality of life for individuals experiencing menstrual-related challenges.","PeriodicalId":20920,"journal":{"name":"Reproductive Sciences","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142676554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the expression of key RNA modification enzymes in a rat varicocele model, aiming to elucidate the relationship between varicocele, oxidative stress, and fertility. Fifteen male Wistar rats were divided into Control, Sham, and Varicocele induction groups. Varicocele was induced in the rats surgically. After 8 weeks, testicular tissues and sperm were collected for analysis, including histopathological assessment and evaluation of sperm parameters, functional tests, and gene expression of key RNA modification enzymes: METTL3 as a writer, ALKBH5 and FTO as erasers, and YTHDF2 as a reader involved in recognizing m6A-modified RNA using qRT-PCR. One-way ANOVA with post-hoc Tukey HSD was used for comparing tests within groups. Varicocele induction resulted in histological changes in testicular tissues, including irregularly variable-sized seminiferous tubules. Sperm parameters were significantly affected, with lower concentration, motility, and higher percentage of abnormal sperm in the varicocele group. Increased levels of oxidative stress markers (Sperm lipid peroxidation, and intracytoplasmic ROS) and sperm DNA damage were observed, indicating the presence of oxidative stress in varicocele. Moreover, the expression of key enzymes involved in RNA metabolism was downregulated in the varicocele group. These findings highlight the detrimental impact of varicocele on testicular health, sperm quality, and gene expression, providing insights into the underlying mechanisms of male infertility associated with varicocele.","PeriodicalId":20920,"journal":{"name":"Reproductive Sciences","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142626905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

HIFU can accurately ablate the uterine fibroids and adenomyosis lesions, without destroying normal myometrium and endometrium, and thus HIFU is a promising alternative to myomectomy in uterine fibroids patients with fertility desire. Several studies have shown that in terms of ovarian endocrine function protection, HIFU treatment is superior to uterine artery embolization, and similar to myomectomy. Existing limited researches show that patients with uterine fibroids have a favorable pregnancy rate and live birth rate, as well as a lower natural abortion rate after HIFU treatment. Pregnancy rate after HIFU treatment for uterine fibroids is not lower than myomectomy, and higher than uterine artery embolization. HIFU may have significant advantages in shortening pregnancy interval compared with myomectomy. However, the proportion of cesarean section delivery after HIFU treatment is relatively high, and gestational uterine rupture after HIFU treatment exist in literature.

Corrected fetal adrenal gland volume (cAGV) is an ultrasound marker that was used to predict preterm labor. The objective was to determine whether cAGV, in conjunction with other maternal risk factors, could predict late-term pregnancy among low-risk pregnant women in order to improve obstetric care. A prospective study recruited 177 low-risk primigravida women. Ultrasound-based cAGV was calculated for all participants at 37 weeks. Participants were followed until the day of delivery; accordingly, they were divided into two groups: Control group (137/177) delivered at term (37 + 0/7-40 + 6/7) weeks and late-term group (40/177) who delivered at (41 + 0/7-41 + 6/7) weeks. Maternal age, body mass index (BMI), and gestational age were collected for all participants alongside ultrasound data such as fetal biometry, gender, and estimated fetal weight. The participants' mean age was (27.32 ± 5.17) years. The cAGV was significantly lower among pregnant women who passed their due dates and was inversely correlated to the gestational age (r = - 0.6, P < 0.001). The cAGV exhibited a high probability of predicting late-term pregnancy (OR = 3.47; 95% CI = 1.37 to 8.79; P = 0.009). In contrast, maternal age, maternal BMI, and the presence of a male fetus did not demonstrate any significance as predictors. The cAGV cut-off value (≤ 277mm3/kg) predicted late-term pregnancy (P < 0.001) at a 77.5% sensitivity and 91.2% specificity. The cAGV can predict late-term pregnancy with good sensitivity and specificity. It is proposed as a promising tool for clinical use as non-invasive ultrasound obtained at no extra cost during routine 2-dimensional ultrasound examinations. More studies are warranted to explore further applications in improving feto-maternal outcomes among late-term pregnnat.","PeriodicalId":20920,"journal":{"name":"Reproductive Sciences","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142626908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unfortunately, the development of curative and effective treatments for ovarian senescence is still a considerable challenge. Currently, mesenchymal stem cells (MSCs)-based therapies for treating various refractory diseases, especially ovarian dysfunction, have been extensively studied and confirmed. However, the mechanisms by which MSCs improve ovarian senescence are not yet clear. Therefore, in this study, a mouse ageing model was generated via the intraperitoneal injection of a D-galactose (D-gal) solution, and the effects of menstrual blood-derived endometrial stem cells (MenSCs) transplantation on the ovarian follicle count, fibrosis level, and degree of apoptosis were evaluated. Subsequently, an ovarian granulosa cell ageing model was induced with H2O2, and CCK-8 assays, flow cytometry, mitochondrial membrane potential analysis and Western blotting were subsequently performed to further investigate the potential mechanism by which MenSCs ameliorate cellular oxidative damage. Overall, our findings demonstrated that MenSCs treatment can increase the cellular antioxidant capacity by activating the NRF2/HO-1 signalling pathway and further ameliorate the inflammatory ovarian microenvironment, apoptosis and dysfunction in ageing mice. These results provide reliable evidence and support for MenSCs-based therapy for ovarian senescence.","PeriodicalId":20920,"journal":{"name":"Reproductive Sciences","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142584170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study aimed to evaluate the effects of L-tartaric acid, an abundantly occurring compound in fruits, on the histostereological and hormonal changes caused by PCOS. Forty adult Sprague Dawley rats were randomly divided into four groups including controls (no intervention), Tartaric acid (40mg/Kg/day from day 21 onwards for 39 days), PCOS (21 days letrozole and then normal saline orally for 39 days), and PCOS + Tartaric acid. After treatments, the ovarian histostereological analysis as well as the level of reproductive hormones including luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradiol, progesterone, and testosterone was measured. PCOS caused a significant decrease in the number of unilaminar, multilaminar, antral, and graafian follicles and increased follicular atresia (p-value < 0.001). Moreover, the weight and volume of ovarian tissue and related structures including cortex, medulla, and cysts increased significantly (p-value < 0.0001). However, corpus luteum volume was significantly decreased (p-value < 0.001). Although significant differences were found in some parameters with the control group (p-value < 0.05), the administration of tartaric acid restored the pathological effects of PCOS on the ovarian histostructure. Furthermore, tartaric acid improved the serum levels of LH, estradiol, progesterone, and testosterone (p-value < 0.05).

Daily dietary intake of various nutrients and adherence to prevalent dietary patterns were compared between men with normal and abnormal semen characteristics. Six dietary patterns were identified following factor analysis of FFQ data. Men with normal semen characteristics showed significantly higher consumption of \"coastal diet\" rich in seafood, fish, cereals, beans, and coconut oil than those with abnormal semen characteristics. Further, the multivariable-adjusted model, adjusted for clinically relevant confounders, like age, body mass index (BMI), physical activity, smoking and sexual abstinence, also showed a lower risk of abnormal semen characteristics among men consuming \"coastal diet\" (odds ratio [OR] = 0.56, 95% confidence interval [CI] 0.37-0.82). In terms of daily nutrient intake, men with normal semen characteristics showed significantly lower consumption of monounsaturated fatty acids (MUFA) compared to men with abnormal semen characteristics (p = 0.008). Our findings suggest that higher consumption of \"coastal pattern diet\" lowers the risk of abnormal semen characteristics.

The observation of sperm agglutination, although not conclusive for the diagnosis of immunological infertility, may suggest the presence of ASA. Nevertheless, ASA may also manifest in the lack of any sperm agglutination. Managing ASA from an andrological perspective depends on the underlying cause and the specific approaches healthcare professionals adopt. The precise etiology of male infertility resulting from ASA remains unclear. Current research has examined the impact of ASA and its prevalence among infertile males to understand the relationship between ASA and changes in semen parameters. However, the findings have been inconclusive. Numerous techniques have been documented for the management of immunoinfertility.
