RESUMO

OBJECTIVE: Today, researchers have succeeded in achieving oocyte-like cells through the in vitro differentiation of stem cells. MicroRNAs are key regulators of oocyte development. In this study we decided to evaluate the expression pattern of microRNA-21, microRNA-15a, and microRNA-372 in oocyte-like cells, to determine the maturation stage of oocyte-like cells. METHODS: Human follicular fluid samples were collected and centrifuged, and their cells were divided into 3 groups; day 7 as control group, days 14 and 21. During this period, the cells were evaluated for their morphological appearance and viability by inverted microscopy. RNA isolation was performed and cDNA was reversely transcribed by specific stem-loop RT primers. Real-time RT-PCR was used to detect microRNA expression. RESULTS: The relative expression of microRNA-21 and microRNA-15a on day 21 was significantly down-regulated compared to the control group (day 7), but microRNA-372 did not show a significant difference. Also, on day 14 compared to the control group (day 7), microRNA-21 did not show a significant difference; but microRNA-15a and microRNA-372 were significantly down-regulated. MicroRNA-21 and microRNA-15a on day 21 compared to day 14 revealed down-regulated levels, but microRNA-372 revealed up-regulated levels. CONCLUSIONS: Our results showed significant decreases in the expression of microRNA-21 and microRNA-15a in oocyte-like cells, as well as in oocytes, which may lead to cytoplasmic maturation, germinal vesicle break down and the completion of meiosis І. In addition, down-regulation expression of microRNA-372 maybe a confirmation that mesenchymal stem cells have differentiated into germ cells, and these cells were differentiated into oocyte-like cells.

RESUMO

BACKGROUND: This research was aimed at assessing the relationship between the follicular fluid (FF) antioxidants activity, aging and in vitro fertilization (IVF) outcome. MATERIALS AND METHODS: The present cross-sectional study was carried out on 65 women undergoing IVF/intracytoplasmic sperm injection (IVF/ICSI) cycles due to unexplained infertility. Ovarian stimulation was performed using the long gonadotropin-releasing hormone (GnRH) agonist protocol. After ovum pickup, FF was collected and processed to measure the level of superoxide dismutase (SOD), catalase (CAT) activity, total antioxidant capacity (TAC) and glutathione (GSH). Day 3 after ICSI, fresh embryos were transferred and later, possible pregnancy was assessed. Patients participating in this study were divided into four groups on the basis of age and pregnancy outcome. RESULTS: SOD activity was not significantly different between the groups (P=0.218). GSH in the group whose participants were aged ≤35 years and were pregnant was higher than that in other groups. CAT activity in groups with younger participants was higher compared to the other groups. The mean TAC was higher in groups with pregnant participants compared to the non-pregnant women. Correlation analysis showed that: GSH level had a significant negative correlation with age (P<0.001, R -0.55) and a significant positive correlation with pregnancy (P=0.015, R=0.30). CAT level also had a significant negative correlation with age (P<0.001, R=-0.42) and the level of TAC had a significant positive correlation with pregnancy (P<0.001, R=0.59). CONCLUSION: According to our results, the levels of TAC, GSH and CAT in younger and pregnant women were higher compared with those undergoing ICSI cycles. Given the correlation of FF antioxidant activity with age and pregnancy, it is necessary to carry out more research on these compounds and the maintenance of pregnancy.

RESUMO

OBJECTIVE: Fetal uterine survival depends on maintaining an immune balance between the mother and fetus. This study aimed to investigate the correlation of blood peripheral natural killer (NK) cells and interferon-gamma (IFN-γ) with recurrent recurrent implantation failure (RIF) and recurrent pregnancy loss (RPL). METHODS: In this case-control study, peripheral blood samples were obtained from three groups of RPL, RIF, and parous women without a history of abortion or infertility problems and analyzed by lymphocyte-based flow cytometry. Afterward, the levels of NK cells and IFN-γ were determined. All data were analyzed using one-way analysis of variance and nonparametric Kruskal-Wallis tests. RESULTS: The level of IFN-γ in the RPL group was significantly higher than that in parous women and the RIF group (P<0.05), whereas its level in the RIF group was not significantly different from the control group (P>0.05). A significant correlation was found between the levels of IFN-γ and NK cells in the RPL group (r=0.481; P=0.02). However, no significant correlation was found between the levels of IFN-γ and the active NK cells in the RPL group (P=0.08). Moreover, no significant correlation was found between the levels of NK cells (whether activated or not) and IFN-γ in the RIF patients (P>0.05). CONCLUSION: Immune dysfunction may not be involved in implantation failure during IVF but may be involved in recurrent miscarriage, probably by increasing IFN-γ levels.

RESUMO

INTRODUCTION: Mental disorders during pregnancy are one of the major public health problems because of its effect on both mother and child, but the prevalence of psychiatric disorders in infertile women is largely unknown to compare psychiatric disorders during and after pregnancies with assisted reproductive therapies (ART) and spontaneous pregnancies. METHODS: This cross-sectional study was conducted on pregnant women referring to midwifery centers in Ahvaz City in 2022. Pregnant women were included in two groups of either pregnancy caused by ART (n= 84) or spontaneous pregnancy (n= 256). The Symptom Checklist-90-R (SCL90-R) was used to assess psychiatric disorders during and after pregnancies. RESULTS: A high percentage of women with spontaneous pregnancy (74.6%) and ART (91.7%) had some degree of psychological disorders. The severity of psychological disorders in both groups was higher during pregnancy than after pregnancy (P<0.001). The intensity of various psychological disorders during and after pregnancy in the ART pregnancy group was significantly higher than the control group (P<0.001). An increased risk of psychiatric disorders during pregnancy was associated with the history of psychiatric disorders [odd ratio (OR): 12.393; P= 0.022], family history of psychiatric disorders (OR:26.168; P<0.001), history of infertility (OR: 19.00; P<0.001), primary infertility (OR: 12.714; P=0.004), infertility duration more than three years (OR: 43.424; P<0.001), and frequency of embryo transfer (OR: 18.939; P=0.045). CONCLUSION: Psychiatric disorders were prevalent among pregnant women in the study area especially in pregnant women with ART. Regular screening programs for mental health problem should be included in an antenatal care service especially in this high-risk group.

RESUMO

Background: Polycystic ovarian syndrome (PCOS) is one of the causes of infertility for which treatment methods do not have a high rate of pregnancy. In this study, the stem cells in the follicular fluid (FF) of patients were grown in the normal FF, and their differentiation into oocytes was evaluated. Materials and Methods: The FF of PCOS patients was centrifuged, and their cells were cultured with and without 20% normal FF for 2 weeks. The cells were evaluated for their morphology by inverted microscope and for markers of stem cells (NANOG and OCT4) and oocytes (zona pellucida (ZP) 2 and ZP3) by RT-PCR and immunocytochemistry. The amount of steroids was measured by enzyme-linked immunosorbent assay (ELISA). Results: The cells were all round on day 0. After that, they had a heterogeneous morphology (fibroblast-like cells, epithelial-like cells, and round oocyte-like cells). In the first week, NANOG and OCT4 genes in the study group were less expressed than those in the control group (P < 0.0001) (~0.5-fold), while ZP2 and Z3 genes were more expressed (P < 0.0001) (~2-fold). In the second week, stem cell genes were more expressed in the control group (~2 fold), and oocyte genes were more expressed in the study group (P < 0.0001) (~2.5-3.11 fold). These results were also confirmed by immunocytochemistry. The amount of steroids was much higher in the study group (three times and five times in two weeks) (P < 0.0001). Conclusions: Stem cells can be obtained from the FF of PCOS, and normal FF has a positive effect on the growth and maturation of oocyte-like cells in vitro.

RESUMO

Introduction: Recent researches have indicated that pregnancies with frozen embryo transfer are associated with the increment of risk of maternal and neonatal complications, especially hypertension during pregnancy. The present study aimed to compare the occurrence rate of gestational hypertension in pregnancy with frozen embryo transfer and normal pregnancy. Materials and Methods: This research, as a retrospective cross-sectional study, was performed on pregnant women with frozen embryo transfer (n = 97) and women with normal pregnancies (n = 164) referring to medical centers under the supervision of Ahvaz University of Medical Sciences in 2021. Women aged 18-35 were included in the study after week 20th of pregnancy. Maternal and neonatal outcomes including hypertensive disorders of pregnancy (including gestational hypertension and preeclampsia), preterm birth (before the week 37th), low birth weight (lower than 2500 g), neonatal asphyxia (Apgar score >7 in minute 5th), intrauterine growth restriction (IUGR) and bleeding in the first trimester of pregnancy were evaluated. The association between frozen embryo transfer and pregnancy outcomes was evaluated using multiple logistic regressions. Results: The findings of this study indicated that pregnancy hypertension was observed in 23 people (23.7%) from the frozen embryo transfer group vs. 18 people (11.0%) from the normal pregnancy group (P = 0.006). Frozen embryo transfer pregnancy has a higher risk of gestational hypertension (OR = 2.521, 95% CI: 1.281-4.962; P = 0.007), preterm birth (OR = 2.264, 95% CI: 1.335-3.840; P = 0.002), and low birth weight (OR = 2.017, 95% CI: 1.178-3.455; P = 0.011). However, the incidence of birth asphyxia (P = 0.850), intrauterine growth restriction (P = 0.068), first-trimester bleeding (P = 0.809), and placenta accreta (P = 0.143) did not show a significant difference between two types of normal pregnancy and frozen embryo transfer pregnancy. Conclusion: Frozen embryo transfer pregnancy was associated with a higher risk of maternal and neonatal complications, hypertension, preterm birth, and low birth weight compared to natural and spontaneous pregnancies.

RESUMO

BACKGROUND: Accreditation is one of the most important methods of quality assurance and improvement in medical education. In Iran, there are no specific midwifery education accreditation standards. This study was designed to develop accreditation standards for midwifery clinical education in Iran. METHODS: This study was performed in Iran in 2021. It consisted of two phases. In the first phase, accreditation standards for midwifery education in the United Kingdom, the United States, Australia and the International Confederation of Midwives were thoroughly examined through a narrative review. The domains obtained from this phase were used as a framework for coding in the second phase. In the second phase, a qualitative study was conducted with a directed content analysis approach to determine standards and criteria for clinical midwifery education accreditation in Iran. Participants were policymakers and senior managers of midwifery education, faculty members of midwifery departments with clinical teaching experience, and final year undergraduate midwifery students. The participants were selected by purposive sampling method, and data collection continued until data saturation. RESULTS: The standards and accreditation criteria of midwifery education from the review study were formed 6 domains: Mission and goals; Curricula; Clinical instructors; Students, Clinical setting; and Assessment. In the second phase, data analysis led to the extraction of 131 codes, which were divided into 35 sub-subcategories, 15 sub-categories, and 6 main categories. CONCLUSION: Implementing the specific and localized standards of clinical midwifery education in Iran can lead to improved quality of clinical education programs.

RESUMO

Background: The issue of infertility is a worldwide challenge, estimated to affect around 50 million couples. This study aimed to evaluate the relationship between infertility stress and sexual function in men and women with infertility. Methods: In this cross-sectional study, 300 men and women with infertility were recruited. A demographic questionnaire, the Fertility Problem Inventory, the Female Sexual Function Scale (FSFI), and the International Index of Erectile Function (IIEF) were used to collect data. Independent t-test, Chi-square, and linear and logistic regressions were used to assess the data. Results: The total score of sexual function in women and men was 22.18 ± 7.86 and 57.7 ± 17.8, respectively. Infertility duration and the ability to pay for the costs of infertility treatment had a significant relationship with sexual function in women. A significant association was found between communication concerns and sexual function scores in men with infertility. Infertile women had more sexual concerns, while infertile men had more communication concerns. Conclusion: This study showed that women with infertility had more infertility stress than men with infertility. Women with higher infertility duration and the inability to pay for the infertility treatment costs impaired sexual function. Women with infertility had more sexual concerns, while Men with infertility had more communication concerns. Policymakers need to consider strategies such as counseling for men and women with infertility to help them cope with their problems, especially their psychological problems. The lack of random enrollment of participants and lack of control group were the limitations of this study.

RESUMO

Magnesium and melatonin are known to exert multiple beneficial effects including anti-inflammatory and antioxidant actions. This study was designed to determine the effects of magnesium and/or melatonin supplementation on metabolic profiles in women with polycystic ovary syndrome (PCOS). This randomized double-blind, placebo-controlled trial was conducted among 84 subjects with PCOS aged 18-40 years old. Patients were randomly assigned based on the random block procedure to take magnesium, melatonin, magnesium plus melatonin, or placebo for 8 weeks. Fasting blood samples were taken at baseline and after the intervention to quantify related variables. After the 8-week intervention, an insignificant marginal difference was seen in waist circumference (WC) between groups (P = 0.085). Magnesium-melatonin co-supplementation resulted in more reductions in hirsutism compared with other groups (P < 0.001). Serum levels of tumor necrosis factor-α (TNF-α) declined significantly in the melatonin and co-supplementation groups compared to baseline (P < 0.05). Also, magnesium plus melatonin was associated with a more increase in total antioxidant capacity (TAC) levels, as compared to the other treatment groups (P = 0.001). Overall, we found a favorable effect of co-supplementation of magnesium and melatonin for 8 weeks in women with PCOS on hirsutism, serum TNF-α, and TAC levels. Furthermore, melatonin independently contributed to decreased serum values of TNF-α.Clinical trial registration number http://www.irct.ir : IRCT20191130045556N1, January 2020.

RESUMO

BACKGROUND: Treatment for polycystic ovary syndrome (PCOS) usually initiates with a series of lifestyle modifications such as diet, weight loss, and exercise. AIMS: We, therefore, conducted this meta-analysis to systematically review and evaluate the possible benefits of LGD on a range of anthropometric, clinical, and biochemical parameters in women with PCOS. METHODS: We performed a systematic search through major indexing databases, including Scopus, Pubmed/Medline, ISI web of science, Embase, Cochrane central, and CINAHL (1966-April 30, 2021) using key concepts of PCOS. RESULTS: Of 935 initial publications, 542 remain after duplicates removal. Then, 141 records were removed at the title and abstract screening level. After excluding 392 literatures, we finally included 8 articles. The final selected studies included 412 overweight and obese individuals with PCOS (207 cases in LGID group and 205 patients in comparators) with a mean age of 21-32 years. Measured emotional health (3 studies, 132 participants, SMD: -1.97; 95%CI:-3.54, -0.40, P = 0.01, I 2 = 89%) and body hair (3 studies, 132 participants, SMD: -0.40; 95%CI:-0.46, -0.35, P < 0.0001, I 2 = 0%), were found to be significantly lower in women in LGD vs control diet groups. Moreover, infertility (3 studies, 132 participants, SMD: 1.45; 95%CI: 0.30, 2.61, P = 0.01, I 2 = 79%) was significantly higher in women in LGD vs control diet groups. CONCLUSION: The present meta-analysis has shown that LGD may play a significant role in reducing the risk and improving the clinical and biochemical features of PCOS. So far the evidences for choosing the best dietary modalities for PCOS are not strong to make a definite recommendation.

RESUMO

Background: Premature ovarian failure is a heterogeneous disorder, leading to early menopause. Several genes have been identified as the cause of non-syndromic premature ovarian failure (POF). Our aim was to explore the genetic defects in Iranian patients with POF. Methods: We studied a family with three females exhibiting non-syndromic POF. WES was performed for one of the affected individuals after ruling out the presence of CGG repeat expansion at fragile X mental retardation 1 gene in the family. Sanger sequencing was used to confirm the candidate sequence variants in the proband, and screening of the detected mutation was performed for the other affected and unaffected members of the family. Results: A homozygous frameshift mutation, c.349delC, was identified in ficolin-3 (FCN3) gene in the proband and two other patients. The parents and two healthy brothers were heterozygous for the mutation, and an unaffected sister was homozygous for wild type. Conclusion: This is the first report of a mutation in FCN3 gene in a family with POF. Our findings can lead to the enhancement of genetic databases of patients with POF, specifically for families with high-risk background.

RESUMO

Submucous myomas have negative effects on fertility. To maintain fertility, conservative treatment should be suggested to women who wish to become pregnant, especially young patients. The patient was a 33-year-old woman, who had had secondary infertility for 3 years. Upon vaginal ultrasound, we noticed a submucous myoma measuring 26 mm x 31 mm with a compressive effect on the anterior surface of the endometrium. Ovarian reserve was low. The gold standard of myoma treatment is surgical intervention. But, for the following reasons: the adverse effects of surgery on the endometrium (intrauterine adhesion), the patient's refusal to undergo a myomectomy and her request for pregnancy, our strategy for treating was to reduce volume of submucous myoma and start the assisted reproductive techniques (ART) cycle, simultaneously. We administered three courses of Gonadotropin-releasing hormone analogues (GnRHa) and then induced controlled ovarian hyperstimulation. Ovum pick up was done. Finally, we transferred two embryos (4 and 6 cells). In subsequent patient visits, ßhCG was positive after 14 days. At the last patient visit, the heart of the embryo was formed. From this finding, it may be concluded that combined GnRHa and ART is the treatment of choice for infertile women with uterine submucous myoma, considering the reduced ovarian reserve and response.

RESUMO

BACKGROUND: Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders among women of reproductive age. This study was designed to investigate the effects of melatonin and/or magnesium supplementation on metabolic profile and levels of sex hormones in PCOS women. METHODS: In an 8-week randomized double-blind placebo-controlled trial, 84 subjects with PCOS aged 18-40 years were randomly assigned based on the random block procedure to take magnesium, melatonin, magnesium plus melatonin, and placebo. Fasting blood samples were obtained at the beginning and end of the study. RESULTS: After intervention, the mean Pittsburg Sleep Quality Index score decreased significantly in both co-supplementation and melatonin groups (P < 0.001). Magnesium supplementation in combination with melatonin resulted in a significant greater decrease in testosterone concentrations compared with the placebo (P < 0.05). Co-supplementation of magnesium-melatonin had significantly reduced serum insulin levels (geometric means difference: - 1.11 (mIU/mL) (percent change: - 15.99)), homeostasis model of assessment-insulin resistance (HOMA-IR) (- 0.28 (- 18.66)), serum cholesterol (mean difference: - 16.08 (mg/dl) [95% CI - 24.24, - 7.92]), low-density lipoprotein cholesterol (LDL-C) - 18.96 (mg/dl) [- 28.73, - 9.20]) and testosterone levels (- 0.09 (ng/ml) (- 25.00)), as compared to the baseline values (P < 0.05). An increase in serum high-density lipoprotein cholesterol (HDL-C) levels was also observed following the administration of the melatonin alone (2.76 (mg/dl) [0.57, 4.95]) or in combination with magnesium (2.19 (mg/dl) [0.61, 3.77]) (P < 0.05). CONCLUSIONS: Co-supplementation with magnesium and melatonin had beneficial effects on sleep quality and total testosterone. Additionally, melatonin supplementation alone was found to be associated with a significant reduction in PSQI score. Moreover, combined melatonin and magnesium supplementation was more effective in improving serum levels of cholesterol, LDL-C, HDL-C and insulin, and HOMA-IR.

RESUMO

BACKGROUND: To evaluate factors affecting oocyte/embryo quality in PolyCystic Ovary Syndrome (PCOS) patients undergoing Assisted Reproductive Technology (ART) cycles. METHODS: This case-control retrospective study was performed on PCOS patients referred to the infertility department of Imam Khomeini Hospital in Ahvaz from October 2017 to September 2019. Demographic and reproductive characterizations including age, gender, abortion history and infertility type (primary and secondary infertility) were extracted from patient's records. TSH, AMH, LH, FSH, prolactin, lipid profile and blood glucose was measured. Biochemistry pregnancy was checked by determination of serum ßHCG level and then, clinical pregnancy was confirmed by observing of pregnancy sac and fetal heart rate using Transvaginal USS. RESULTS: One-hundred thirty-five patients include 45 PCOS and 90 Non-PCOS patients with mean age of 31.93 ± 5.04 and 30.8 ± 5.38 (p = 0.24) were considered as case and control groups respectively. Retrieved oocyte numbers were significantly higher in PCOS patients (p = 0.024), but there was no significant difference in number of oocyte subtypes (MI, MII and GV) between two groups. The embryo numbers and its subtypes did not differ significantly in both groups. The clinical pregnancy rate was insignificantly lower in PCOS patients (p = 0.066) and there was a significant correlation between retrieved oocyte numbers with age(r= -0.2, p= 0.022) and AMH level (r = 0.433, p < 0.0001) respectively. Cholesterol level had shown a positive significant correlation with number of MI oocytes (r = 0.421, p = 0.026) and MII oocytes significantly affected by age (r= -0.250, p = 0.004) and AMH level (r = 0.480, p < 0.0001). Using Receiver operation characteristic (ROC) curve analysis, the cut-off value of total number of oocytes was > 10.5 with area under curve of 0.619±0.054(sensitivity 55.56% and specificity 69.66%) CONCLUSIONS: The results of this study showed that although the number of oocytes in PCOS patients was significantly higher than non-PCOS patients, the quality of oocytes was not statistically different. The number and quality of embryos were not significantly different in both groups. Our results indicated a significant relationship between the level of AMH and the number of retrieved oocytes and embryos. We found there is a significant correlation between cholesterol level and number of MI oocytes.

RESUMO

Follicular fluid (FF) is essential for developing ovarian follicles. Besides the oocytes, FF has abundant undifferentiated somatic cells containing stem cell properties, which are discarded in daily medical procedures. Earlier studies have shown that FF cells could differentiate into primordial germ cells via forming embryoid bodies, which produced oocyte-like cells (OLC). This study aimed at isolating mesenchymal stem cells (MSC) from FF and evaluating the impacts of bone morphogenetic protein 15 (BMP15) on the differentiation of these cells into OLCs. Human FF-derived cells were collected from 78 women in the assisted fertilization program and cultured in human recombinant BMP15 medium for 21 days. Real-time polymerase chain reaction and immunocytochemistry staining characterized MSCs and OLCs. MSCs expressed germline stem cell (GSC) markers, such as OCT4 and Nanog. In the control group, after 15 days, OLCs were formed and expressed zona pellucida markers (ZP2 and ZP3), and reached 20-30 µm in diameter. Ten days after induction with BMP15, round cells developed, and the size of OLCs reached 115 µm. A decrease ranged from 0.04 to 4.5 in the expression of pluripotency and oocyte-specific markers observed in the cells cultured in a BMP15-supplemented medium. FF-derived MSCs have an innate potency to differentiate into OLCs, and BMP15 is effective in promoting the differentiation of these cells, which may give an in vitro model to examine germ cell development.

RESUMO

BACKGROUND: The phenomenon of infertility may be derived from different factors - either in males or females or both genders, including few unexplained factors. It is generally managed by medical and surgical treatments. OBJECTIVE: To find a relation of occurrence of spontaneous pregnancy (SP) with effective factors in infertility. MATERIALS AND METHODS: This cross-sectional study was conducted at two referral infertility centers (university and privacy center) in the southwest of Iran from March 2015 and March 2016 on 655 infertile couples, who were divided in two groups of with (n = 31) and without (n = 624) SP. The variables included female and male age, male smoking, male job, the place of living, the causes of infertility, the type and duration of infertility, and the subgroups of infertility causes. RESULTS: Infertility may be caused due to both male- and female- related factors (47.5%). While female-related infertility was found in 31.5%, male-related infertility in 14.5%, and infertility due to unexplained factors in 6.6% of our patients. The rate of SP was 4.7%, which had a significant relation with the duration of infertility (p = 0.01), with women's age (p = 0.048), unexplained infertility (p = 0.001), and husband's job (p = 0.004). CONCLUSION: The occurrence of SP in infertile couples was related to age of the female partner, the duration of unexplained infertility, and the male partner's job.

RESUMO

Mutations or altered expression of PRM1 gene have been associated with male infertility. This study aimed to analyse pathogenic variations of PRM1 gene in Iranian Arab infertile men with oligoasthenoteratozoospermia that was carried out for the first time in this population. Genomic DNA was used to perform PCR sequencing in PRM1 untranslated regions, exons and intron. Also, bioinformatics analysis was recruited to discover the possible effect of detected variations. Two pathogenic variations were seen in two men with oligoasthenoteratozoospermia, which were not found in the control group. The cDNA.384G>C variation is novel and was located in the 3' untranslated region, and cDNA.42G>A variation is reported for the first time related to male infertility and was found in 5' untranslated regions. Bioinformatics analysis showed that the minimum free energy was increased from -19.9kcal/mol to -13.1kcal/mol due to the cDNA.384G>C variation at hsa-miR-4326's seed site. More analysis revealed cDNA.42G>A located in transcription factors binding site, E1 and MYOD, which was detected as a promoter-associated region, and generally have regulatory features for acetylation and methylation. In conclusion, two pathogenic variations were recognised in regulatory areas of PRM1 gene, which might interfere with some critical factors related to PRM1 gene expression, hence cause male infertility.

RESUMO

OBJECTIVE: Vitamin D receptor (VDR) is expressed in human spermatozoa. However, the role of vitamin D (VD) in human male reproduction has not yet been clarified. In this study, effects of VD on sperm parameters and its apoptosis in asthenozoospermic and healthy men were evaluated. METHODS: The study was carried out on discharged semen samples of 80 asthenozoospermic and healthy men. The samples were divided into control and experimental groups (received 20 µMol of VD). This study assessed sperm motility using the Makler chamber, their morphology by Diff quick, apoptosis and necrosis by Annexin-V and TUNEL assays, and their chromatin integrity was assessed by Aniline blue and Toluidine blue staining, according to WHO guidelines. RESULTS: The results revealed that: 1) the total number of motile sperms was increased by VD in both groups, but it was only significant in the asthenozoospermia group. 2) The progressive motility was increased with significant difference in both groups.3) Morphology of sperm did not show any changes due to VD in any of the groups. 4) Early apoptosis and necrosis of sperms were reduced in both groups, but the results of late apoptosis showed no statistical difference in these groups. 5) The percentage of positive toluidine blue was significantly decreased after using VD in the asthenozoospermia group. CONCLUSION: VD could improve motility, early apoptosis, and sperm necrosis, especially in asthenozoospermic men and it could be used for therapeutic opportunities.

RESUMO

In treatment cycles of in vitro fertilization (IVF), 15% of the oocytes are immature and in the germinal vesicle (GV) phase. In rare occasions, more than 50% of the oocytes of a patient in a cycle are immature. Selecting fertility treatment for patients in this situation can be very challenging. The patient described in this report was a 35-year-old woman with primary infertility for 10 years. She had undergone fertility treatment six times, with no success. In her cycles, more than 50% of the oocytes were immature and in the GV phase. To address the situation, we developed a coordinated protocol involving medical and embryology procedures, analyzed the patient's medical records, and looked into the reasons of prior treatment failure. The development of a special and coordinated effort - instead of having medical and embryology teams working in isolation - proved efficient at providing better outcomes to the patient.

RESUMO

BACKGROUND: A considerable evidence suggests that maternal inflammation dysregulation may play as a risk factor for both maternal and neonatal outcomes. Objective: The study's objectives were designed to evaluate the correlation between serum C-reactive protein (CRP) levels, as an inflammation factor, preterm delivery, and small for gestational age (SGA) births. MATERIALS AND METHODS: This prospective cohort study was conducted on 120 singleton pregnant women with gestational age less than 20 wk. Maternal CRP serum concentration was measured before 20 wk gestation. Patients were followed-up until the delivery and final outcomes of pregnancy were recorded in terms of preterm delivery and SGA births. Results: Serum CRP levels in participants with normal fetuses and SGA births were 4.09 ± 1.35 mg/l and 6.04 ± 3.29 mg/l, respectively (p = 0.19), while in cases of preterm delivery, it was 9.63 ± 5.78 mg/l (p < 0.001). By using receiver operating characteristic (ROC) curve, serum CRP levels (cut-off point 5.27 mg/l, area 0.836) had acceptable diagnostic accuracy value in distinguishing preterm delivery (sensitivity (75%), specificity (86.1%), positive predictive value (37.5%), negative predictive value (96.87%), accuracy (85%)) and serum CRP levels (cut-off point 6.67 mg/l, area 0.673) in distinguishing SGA births (sensitivity (50%), specificity (91.2%), positive predictive value (23.07%), and negative predictive value (97.19%), and accuracy (89.16 %)). CONCLUSION: Higher maternal serum CRP levels measured early in pregnancy may associate with higher risk of preterm delivery and SGA.
