RESUMO

RESEARCH QUESTION: Are there differences in immature oocyte retrieval following luteal phase in-vitro maturation (IVM) compared with follicular phase IVM in women with oocyte maturation abnormalities (OMAs). DESIGN: From January 2019 to May 2023, a retrospective cohort study at a private IVF centre included 36 women with 53 IVM cycles in Group 1 (follicular phase) and 24 women with 32 IVM cycles in Group 2 (luteal phase). Additionally, nine women had both follicular and luteal phase IVM cycles for intracycle variability analysis. RESULTS: There were no differences in oocyte maturation stages between the groups at collection. Group 1 and Group 2 exhibited comparable median metaphase II oocyte rates per patient at 48 h after collection [40.0%, interquartile range (IQR) 0.0-66.7% versus 22.5%, IQR 0.0-52.9%] (P = 0.53). The median fertilization rate in Group 1 (66.7%, IQR 50.0-66.7%) was found to be comparable with that in Group 2 (66.7%, IQR 50.0-66.7%). There were no significant differences in the yielded embryo grades and pregnancy rates between the groups. Comparing follicular and luteal phase IVM within the same menstrual cycle in nine patients, no differences were observed in metaphase II oocyte maturation rates (P > 0.05). CONCLUSIONS: This study found no significant differences in oocyte maturation, fertilization rate, embryo quality or pregnancy outcomes between luteal phase and follicular phase IVM in women with OMAs. These findings suggest that luteal phase IVM can be used similarly to follicular phase IVM, offering a potential avenue to enhance embryo yield for women with OMAs.

RESUMO

RESEARCH QUESTION: Are there differences between in-vitro maturation (IVM) primed with letrozole-human chorionic gonadotrophin (HCG) and IVM primed with FSH-HCG in women with oocyte maturation abnormalities (OMAs), defined as at least two failed IVF cycles where immature oocytes were retrieved? DESIGN: This retrospective study was conducted at a private fertility clinic from January 2009 to April 2023. The final analysis included 75 women in Group 1 (IVM primed with FSH-HCG) and 52 women in Group 2 (IVM primed with letrozole-HCG). RESULTS: A significantly higher median number of oocytes was obtained in Group 1 compared with Group 2 {9 [interquartile range (IQR) 1-5] versus 5 (IQR 1-18); P < 0.001}. However, no differences in oocyte maturation stage at collection were found between the groups (P > 0.05). At the end of IVM, Group 1 had 73/666 mature oocytes and Group 2 had 106/322 mature oocytes, and the median metaphase II oocyte rate per patient was higher in Group 2 [33.3% (IQR 66.7-100.0%) versus 0.0% (IQR 0.0-22.2%); P < 0.001]. Moreover, Group 2 demonstrated a higher median fertilization rate [66.7% (IQR 50.0-100.0%) versus 50.0% (IQR 0.0-66.7%); P = 0.027]. Group 2 had a higher proportion of Grade 2 embryos (58.5% versus 6.3%), and Group 1 had a higher proportion of Grade 3 embryos (93.8% vs 24.4%; P < 0.001). Notably, all pregnancies obtained in the study were in Group 2 (5 versus 0; P = 0.042). CONCLUSIONS: IVM primed with letrozole-HCG in women with prior failed IVF cycles due to OMAs may result in mature oocytes, clinical pregnancies and live births. The effectiveness of letrozole priming for the subtypes of OMAs needs further investigation, with studies including greater numbers of cases.

RESUMO

Up to 70-80% of women of reproductive age may be affected with the most common uterine tumors, known as fibroids or myomas. These benign tumors are the second most prevalent cause of surgery among premenopausal women. Predictions show that the occurrence of myomas in pregnancy will increase, and that the risk of having myomas during pregnancy increases with advanced maternal age. Although most women with fibroids do not experience any symptoms during pregnancy, up to 30% of women experience problems during pregnancy, childbirth, and the puerperium. The viability of myoma excision during cesarean surgery (CS) is a contentious issue raised by the rising incidence of myomas in pregnancy and CS rates. A new surgical procedure for removing fibroids using a trans-endometrial approach, which involves making an incision through the decidua itself, has put into doubt the long-standing practice of cesarean myomectomy (CM) with a trans-serosal approach. Some authors have recently advocated for this last approach, highlighting its advantages and potential uses in real-world situations. The purpose of this paper is to critique the present approach to cesarean myomectomy by analyzing the clinical and surgical distinctions between the two approaches and providing illustrations of the CM methods.

RESUMO

The possible correlation between nausea and vomiting during pregnancy (NVP) with obsessive-compulsive disorder (OCD) and alexithymia were examined in this cross-sectional study. A cohort of pregnant women at the first trimester of pregnancy experiencing NVP were divided into three groups, according to severity (mild, moderate and severe) with the Pregnancy Unique Quantification of Emesis and Nausea (PUQE) test. The Maudsley Obsessive Compulsive Disorder Scale (MOCQ) and the Toronto Alexithymia Scale (TAS-20) were applied. Scores of scales were compared in all three groups, and the relationship between NVP severity and OCD and alexithymia was evaluated. On the 110 enrolled pregnant women, 42 had mild, 36 had moderate and 32 had severe NVP. Pregnant women with mild NVP had lower MOCQ scores than those with severe NVP (p = .010). Total scores of TAS-20 were higher among subjects with greater NVP severity (p < .001). PUQE scores were demonstrated significant correlations with MOCQ and total and subsection scores of the TAS-20, regardless of NVP groups. Study results showed that women with more pronounced OCD and/or alexithymia can experience somatic complaints, such as NVP, particularly intense in their first trimester of pregnancies. For this reason, psychotherapy in addition to medical treatments could be recommended to pregnant women with severe NVP.Impact statementWhat is already known on this subject? NVP is a condition experienced by most women, particularly in the first trimester of pregnancy, which can be affected by the psychosomatic condition of the pregnant woman.What do the results of this study add? The severity of nausea and vomiting according to PUQE test were significantly associated with OCD and alexithymia presence in pregnant women during their first trimester period.What are the implications of these findings for clinical practice and/or further research? These findings might demonstrate the symptoms of NVP are correlated to OCD, as well as alexithymia. Longitudinal studies are required to demonstrate the clear causal relationship between NVP and psychiatric symptoms as in OCD and in alexithymia.

RESUMO

OBJECTIVE: Pregnants and puerperas show different perceptions of their body image and appearance, so authors investigated their perceptions related to pregnancy and puerperium, evaluating their views on cosmetic surgery, by a cross-sectional study. MATERIALS AND METHODS: 5-item questionnaires were administrated to women at first pregnancy and puerperas. Patients were submitted also to Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI) and Body Image Inventory (BII) analysis, indicating the level of anxiety, depression and body dissatisfaction for somatic changes during pregnancy and after childbirth. RESULTS: 186 healthy women, aged between 25-35 years, equally divided in pregnancy and puerperium, were compared in terms of body image, with no significant difference between groups. Analyzing the item "cosmetic surgery is required after all pregnancies", there was a significant difference in puerperas and the item "cosmetic surgery is necessary for postpartum" was the principal. The comparison of BII, BDI, BAI values between pregnants and puerperas showed a significant difference between groups (p<0.00), with higher scores in postpartum patients. CONCLUSION: Body shape and physical dissatisfaction during pregnancy is linked with increased risk of depression in pregnancy and puerperium, pushing women to opt for cosmetic surgery, especially in puerperium.

RESUMO

OBJECTIVE: This study aims to determine the effects of early and late onset estrogen supplementation on the immature oocyte retrieval, fertilization and clinical pregnancy rates in follicle stimulating hormone (FSH) and human chorionic hormone (hCG) primed in vitro maturation (IVM) cycles of the patients with polycystic ovary syndrome (PCOS). METHODS: This is a retrospective analysis of 161 patients with PCOS who underwent FSH and hCG primed IVM. Group 1 included 120 patients who received early onset estrogen supplementation while group 2 consisted of 41 patients who had late onset estrogen supplementation in primed IVM cycles. Immature oocyte (germinal vesicle and/or metaphase I) retrieval and fertilization rates were the primary outcomes, whereas clinical pregnancy and live rates were the secondary outcomes. RESULTS: Group 1 patients had significantly higher body mass index and more previous IVF attempts (p = 0.001 and p = 0.008, respectively). All of the retrieved oocytes from the PCOS patients were either germinal vesicle or metaphase I oocytes and there were no metaphase II oocytes among the retrieved oocytes. Both groups had statistically similar numbers of metaphase I and fertilized oocytes (p > 0.05 for both). However, group 1 patients had significantly lower number of germinal vesicle oocytes but significantly higher number of metaphase II oocytes (p = 0.001 for both). Both groups had statistically similar fertilization (85.0% vs 78.0%), clinical pregnancy (49.2% vs 43.9%) and live birth (37.5% vs 39.0%) rates (p > 0.05 for all). CONCLUSION: Early onset estrogen supplementation appears to improve the quality of retrieved immature oocytes and contribute to the maturation of oocytes in stimulated IVM cycles.

RESUMO

INTRODUCTION: the aim of this study was to determine whether maternal serum IL-6 and postnatal melatonin levels change with the mode of delivery. MATERIALS AND METHODS: a prospective controlled study was performed on pregnant women (17-43 years) over 37 weeks of pregnancy. Patients were divided into three groups according to the route of delivery: Group 1) 30 women delivering by vaginal route; Group 2) 30 delivering by iterative cesarean section (CS); Group 3) delivering by emergency CS. Maternal serum IL-6 levels were measured before and after delivery, and maternal colostrum melatonin levels after delivery, and the results between the 3 groups compared. RESULTS: pre-delivery and post-delivery maternal serum IL-6 levels were significantly higher in patients who delivered vaginally than in patients who delivered by the abdominal route (p<0.01). Maternal colostrum melatonin levels of patients after delivery were significantly higher in patients who delivered vaginally (32.88±7.16 ng/L) than in patients who delivered by elective and emergent cesarean deliveries (24.86±2.40 ng/L and 23.73±4.03 ng/L, respectively) (p<0.01). CONCLUSION: These data support, should there ever be a further need, the benefit of vaginal delivery over cesarean section, in which cytokine and melatonin levels are reduced compared to vaginal delivery.

RESUMO

The follicle must fulfill the following criteria if it is to survive the period between early embryonic life and the luteinizing hormone (LH) peak. It should (i) be surrounded by pregranulosa cells; (ii) complete the first meiotic division and become dormant; and (iii) continue metabolism during the dormant stage. Interaction between the natriuretic peptide precursor type C (Nppc) and its receptor, natriuretic peptide receptor 2 (Npr2), affects female fertility through the production of oocytes with developmental capacity and maintain oocyte meiotic arrest. While Nppc is expressed in mural cells, cumulus cells express Npr2. Nppc/Npr2 system exerts its biological function on developing follicles by increasing the production of intracellular cyclic guanosine monophosphate (cGMP). This pathway not only contributes to the development of ovary and the uterus, but aids the formation of healthy eggs in terms of their morphological and genetic aspects. A defect in this pathway leads to asmall ovarian size, string-like uterine horns, and thin endometrium and myometrium. Disorganized chromosomes, abnormal cumulus expansion and early meiotic resumption occur in animals with defective Nppc/Npr2 signaling. The types and number of oocytes also decrease when there is incompetent Nppc/Npr2 signaling. This paper extends on most recent and relevant experimental evidence regarding Nppc/Npr2/cGMP signaling with regard to its crucial role in maintaining oocyte meiotic arrest and the production of oocytes with developmental capacity. We further discuss whether the agonist or antagonist forms of the members of this exciting pathway can be usedfor triggering final oocyte maturation.

RESUMO

Obesity and hyperandrogenemia are known to have adverse effects on both developing follicle and endometrium receptivity in polycystic ovarian syndrome (PCOS). Insulin resistance also contributes to this dilemma as a cause or a consequence and leads to worsening of the clinical picture. The difficulty in obtaining pregnancy despite the presence of a large number of oocyte has concentrated our attention on oocyte quality and development. However, the occurence of subfertility has also caused us to investigate the presence of different etiologic agents in non-obese PCOS women with normal androgen and insulin levels. In this context peptides have become the most accused and investigated molecules in cases of impaired fertility due to PCOS. Most of the studies investigating the relationship between PCOS and peptide did not support each other. The difficulties in measuring peptide levels as well as the individual variations in peptide synthesis and release are possible causes of this incongruity. For all these reasons, the incorporation of studies investigating the relationship between PCOS, peptide and subfertility in an article has become critical to pioneering future work. Understanding the association between peptides and subfertility will help us to understand the effects of peptides on failed fertility in PCOS. Moreover, updating our knowledge about peptides may allow us designing new drugs to to treat subfertility in PCOS. This review provides a general summary of the mechanisms of action of neuroendocrine peptides in regulating reproductive events. Since it is not usual to discuss all peptides in this context, only the effects of key central and peripheral peptides on fertility in PCOS have been extensively addressed.

RESUMO

OBJECTIVE: Spontaneous ovarian hyperstimulation syndrome (SOHSS) is an extremely rare complication that deserves a multidisciplinary approach together with a thorough investigation for the correct diagnosis of the underlying pathology. The aim of this study was to present a case of severe SOHSS resistant to all interventions and to discuss the available interventions to overcome such a rare and serious clinical situation. CASE REPORT: We report a case of severe, life-threatening spontaneous OHSS with a normal nine weeks singleton pregnancy in a 25-year-old nulliparous woman, which resulted with pregnancy termination and continuation of disease progression until the dose of cabergoline was increased to 1.5 mg/day. CONCLUSION: This case report emphasizes that patients with life-threatening SOHSS resistant to all medical and surgical interventions may benefit from higher doses of cabergoline. Although spontaneous OHSS is extremely rare, it is potentially a life-threatening clinical entity in its severe form and needs time management and detailed examination of the underlying causes.

RESUMO

STUDY OBJECTIVE: To compare pregnancy outcomes in PCOS women undergoing transvaginal ovarian injury (TVOI) and laparoscopic ovarian drilling (LOD) DESIGN: 126 infertile patients with PCOS were included in this prospective cohort study CANADIAN TASK FORCE CLASSIFICATION OF LEVEL OF EVIDENCE: IIA. SETTING: University-affiliated fertility center. PATIENTS: Sixty-seven infertile patients with the history of failed in vitro maturation underwent follow-up as the TVOI group. Fifty-nine infertile women who underwent LOD acted as controls. All subjects had PCOS with menstrual irregularity and were anovulatory by repetitive serum progesterone levels. INTERVENTIONS: The LOD group underwent six cauterizations of a single ovary with 30W for 4-6 s. Failed IVM subjects with 20-30 needle punctures per ovary acted as the TVOI group. Subjects were followed for six months. MEASUREMENTS AND MAIN RESULTS: There was not a significant difference between the groups when the cases were evaluated in terms of spontaneous pregnancy or miscarriage rates. BMI levels decreased in both the TVOI and the LOD groups in a similar fashion. However, serum AMH and AFC decreased greater after LOD than they did with TVOI over the six-month duration of the study (p < 0.001 in both cases). CONCLUSIONS: Preliminary data suggest that TVOI likely represents a safer, less costly and equally effective manner of surgical ovulation induction in anovulatory PCOS women when compared to LOD.

RESUMO

BACKGROUND Preptin and amylin are pancreatic hormones which participate in glucose homeostasis. This study aimed to evaluate how serum preptin and amylin levels are altered in polycystic ovary syndrome (PCOS) patients and healthy women based on BMI groups (<25 kg/m² and ≥25 kg/m²). MATERIAL AND METHODS This was a prospective randomized control study of 40 PCOS patients and 40 healthy women who were matched with respect to BMI (<25 kg/m² and ≥25 kg/m²). RESULTS When compared to the healthy women, PCOS patients had significantly higher ovarian volumes, Ferriman-Gallwey scores, and free and total testosterone levels, but significantly lower amylin concentrations (p=0.001, p=0.001, p=0.049, p=0.021, and p<0.001, respectively). Both the normal-weight and overweight PCOS patients had significantly lower amylin levels than the normal-weight and overweight controls (p<0.001, p=0.009, p=0.001, and p=0.001, respectively). Amylin levels were negatively and significantly correlated with the Ferriman-Gallwey scores (r=-0.272, p=0.001) and ovarian volume (r=-0.206, p=0.007). Serum preptin levels were not elevated in either group. CONCLUSIONS Serum preptin levels are statistically similar in PCOS patients and BMI-matched healthy controls. Serum amylin levels are significantly higher in healthy controls than PCOS patients whether they are slim or overweight. These findings suggest the presence of mechanisms that can prevent the elevation in serum amylin concentrations that can occur in response to the impaired glucose metabolism in PCOS patients.

RESUMO

The aim of this study is to present the clinical outcomes of a random start, a spontaneous folliculogenesis protocol versus Clomiphene Citrate and Gonadotropin treatment in women with occult premature ovarian insufficiency. Women underwent treatment between 1 February 2009, and 30 May 2016. 41 women were treated with the random start protocol while 48 cases received ovarian stimulation with clomiphene and gonadotropins. All included cases met the criteria of 4 months of oligo-ovulation, follicular-stimulating hormone levels over 30 IU/L and anti-Mullerian hormone levels below 0.30 ng/mL. The random start protocol involved following the subjects for up to 6 months until spontaneous folliculogenesis occurred. The mean number of oocytes collected, mature oocytes, fertilized oocytes, and grade II embryos were significantly higher in the random start protocol (p < .05). The doses of gonadotropin administration and hCG were significantly lower in the random start protocol (p < .05). The clinical pregnancy and live birth rates were significantly higher in the random start protocol (p < .05). Likely stimulation is of little benefit in women with occult premature ovarian insufficiency. Observation while waiting for spontaneous folliculogenesis results in better outcomes, and less oocyte collections.

RESUMO

OBJECTIVE: In vitro maturation (IVM) of human oocytes can be an alternative treatment option to conventional in vitro fertilization. Women with polycystic ovary syndrome (PCOS) are considered the classical candidates for IVM because of the associated ovarian morphology and because IVM diminishes the risk of developing ovarian hyperstimulation syndrome. The objective of this study was to identify predictive factors for live birth in a cohort of women with PCOS who underwent IVM. METHODS: This retrospective study included 159 patients with PCOS who had IVM cycles in which single or double embryo transfer was performed. The IVM protocol included three days of gonadotropin ovarian stimulation and hCG priming when the leading follicle size was 10-12 mm. Collected cumulus-oocyte complexes were cultured for 24 h for maturation. Intracytoplasmic sperm injection (ICSI) was used for fertilization. Embryo transfer was performed two days after fertilization. Demographic and clinical parameters were analyzed with logistic regression to identify predictors for live birth. RESULTS: The women's mean age was 27.4 years, the mean number of retrieved oocytes was 14, and the live birth rate was 34.6%. The logistic regression revealed the following significant factors for live birth: infertility duration (OR 0.9; 95% CI, 0.82-0.98), number of collected oocytes (OR 1.56; 95% CI, 1.01-3.2), embryo cell number (OR 2.1; 95% CI, 1.4-3.5), and embryo grade (OR 1.84; 95% CI, 1.13-4.2). CONCLUSION: Infertility duration, oocyte number, embryo cell number, and embryo grade were the most significant predictors for live birth after IVM in PCOS patients. These prognostic factors can be used when planning treatment or counselling patients.

RESUMO

A 30-year-old woman with premature ovarian insufficiency had two follicles measuring 17 mm and 14 mm on day 3 of her menstrual cycle. Serum oestradiol concentration was 210 pg/ml. Recombinant human chorionic gonadotrophin was given and 5 mg/day letrozole started orally. One metaphase II oocyte was collected 36 h later. A 4-cell embryo was vitrified on the second day after fertilization. Letrozole was stopped on cycle day 8 due to absence of any other visible antral follicles. Oestradiol valerate 6 mg/day was started and the endometrium was 9.2 mm on cycle day 11. The embryo was warmed and transferred on cycle day 13, the 8th day after oocyte retrieval. Luteal phase support with progesterone, oestradiol and low molecular weight heparin was started on the day of transfer and continued until the 10th gestational week. A healthy girl weighing 3200 g was born at term. Early follicular phase oocyte collection did not result in early opening of the implantation window. Apparently secretory transformation was not started until luteal phase support, enabling a cleavage stage embryo transferred 8 days later to implant. Either corpus luteum formation could be disrupted or the endometrium could remain unresponsive to progesterone during the early follicular phase.

RESUMO

Objective: This study aims to investigate the developmental potential of immature oocytes and questions whether unstimulated in vitro maturation (IVM) can be used as a treatment in women with oocyte maturation abnormalities. Material and Methods: This cohort study was conducted between September 2019 and December 2022, and it included 12 women who underwent unstimulated, non-hCG priming IVM.Oocytes were incubated in in vitro maturation medium for 26-48 hours and evaluated to compare their maturation profiles with the immature oocytes retrieved from the same patients in their previous IVF cycles. Results: Among the twelve women in the study, eleven (91.6%) underwent whole exome sequencing (WES) analysis. Of these, ten women presented a total of 18 mutations, excluding Case 1, which had no previous mutation analysis. Of the mutations identified, 9 (50%) were located in the FSHR gene, 5 (27.8%) in the TUBB8 gene, 1 (5.6%) in the ZP1 gene, 1 (5.6%) in the SLFN14 gene, 1 (5.6%) in the AR gene, and 1 (5.6%) in the STEAP3 gene. Apart from one woman with resistant ovary syndrome,none of the women treated with unstimulated in vitro maturation had oocyte maturation . Remarkably, the only patient to achieve oocyte maturation in an unstimulated IVM cycle was Case 11, who had ROS and a single FSHR mutation. Conclusion: Unstimulated non hCG primed IVM has no value in the treatment of OMAS, except in cases with resistant ovary syndrome. However this study led our team to develop novel treatment options based on physiological mechanisms for some subtypes and supraphysiological approach for other subtypes of oocyte maturation abnormalities.

RESUMO

Objectives: The safety of cesarean myomectomy has been proven by previous studies. Our study aimed to reveal the long-term perinatal, obstetric, and surgical outcomes of cesarean myomectomy (CM) by comparing different CM techniques. Material and methods: This retrospective multicentric case-control study involved 7 hospitals and included 226 singleton pregnancies that underwent repeated cesarean section (CS) between 2015 and 2020. Among these pregnancies, 113 of 226 cases had CM (Group A), and 113 had only CS (Group B). Of the 113 cases in which CM was performed, 58 underwent endometrial myomectomy (EM) (Subgroup A1) and 55 underwent serosal myomectomy (SM) (Subgroup A2). The groups were compared in terms of obstetric, perinatal, and surgical outcomes, and fibroid recurrence, myomectomy scar healing rate, and adhesion formation were noted. Results: There was no significant difference between the groups in terms of maternal age, body mass index, gravidity, parity, and fibroid diameter in previous CS (p > 0.05). In the perinatal and obstetric evaluation of the groups, there was no significant difference between the groups in terms of neonatal weight, Apgar score, fetal growth restriction, preterm premature rupture of membranes, preterm delivery, hypertension in pregnancy, and diabetes mellitus (p > 0.05). The fibroid recurrence rate was 28.3%, and the myomectomy scar good healing rate was 99.1%. There was no difference between the groups in terms of CS duration, preoperative and postoperative hemoglobin levels, perioperative blood transfusion rates, febrile morbidity, and prolonged hospitalization (p > 0.05). In terms of adhesion formation, although the adhesion rate of the SM group was higher than that of the EM group, no statistically significant difference was detected between the groups. Conclusion: This study showed that in pregnancies following CM, obstetrical, perinatal, and surgical outcomes were unaffected. Obstetricians can safely use CM, either the trans-endometrial or serosal technique, as it is a safe and effective method with long-term results.

RESUMO

Objective: To review the outcomes of in vitro maturation (IVM) and in vitro fertilization (IVF) in women with empty follicle syndrome (EFS). The study evaluated the genetic underpinnings of EFS by analyzing mutations. Materials and Methods: This retrospective case series involving 17 women with EFS over at least 2 IVF cycles was conducted. The study also employed whole-exome sequencing to analyze the genetic mutations. The treatment approaches included letrozole-primed IVM, follicle-stimulating hormone (FSH)-human chorionic gonadotrophin (hCG)-primed IVM, and conventional IVF. Results: The average female age was 31.5±4.6 years, and the duration of infertility was 7.3±3.5 years. Four patients underwent IVF. IVM oocyte collections yielded oocytes in 12 of 13 subjects. Of these, 75% (9/12) yielded MII oocytes after 48 h of IVM media incubation. Six subjects had fertilized embryos, resulting in a 40.9% intracytoplasmic sperm injection (ICSI) fertilization rate (9 embryos/22 MII oocytes). Genetic analysis revealed mutations in seven patients. This study demonstrated the partial efficacy of letrozole-primed IVM plus growth hormone and FSH-hCG primed IVM protocols. No pregnancies or live births were recorded after IVM. One ongoing pregnancy post-IVF and one spontaneous live birth were observed. Conclusion: Inter-cycle variabilities were observed in women with oocyte maturation abnormalities (OMAs). Almost all patients with EFS had oocytes collected during IVM following IVF. These oocytes have limited potential for maturation, fertilization, and live birth, as demonstrated by the low rates observed after IVM culture and ICSI. These conditions are observed in OMAs due to defects in the oocyte machinery. The proposed flowchart provides a comprehensive classification approach for various forms of EFS.

RESUMO

BACKGROUND: The objective of this study is to evaluate the effect of HPV diagnosis on the sexual function and anxiety levels of Turkish women. METHODS: A total of 274 female patients who tested positive with HPV were included in the study and categorized into four groups: Group 1 (HPV 16/18 with normal cytology), Group 2 (HPV 16/18 with abnormal cytology), Group 3 (other high-strain HPV with normal cytology), and Group 4 (other high-strain HPV with abnormal cytology). All patients filled out the Beck Anxiety Inventory (BAI) and Female Sexual Function Index (FSFI) at the time when they tested positive for HPV and during the two-month and six-month follow-ups. RESULTS: Significant increases were observed in BAI scores in all four groups, whereas significant decreases were observed in total FSFI scores in Groups 1 and 2 only(p < 0.05). BAI scores of Groups 1 and 2 were significantly higher than those of Groups 3 and 4 (p < 0.05). FSFI scores of Groups 1 and 2 measured during the sixth-month follow-up were significantly decreased (p = 0.004 and p < 0.001, respectively). CONCLUSIONS: Our findings suggest that patients with HPV 16 and 18 positivity and abnormal cytological findings are more likely to have high anxiety and sexual dysfunction.

RESUMO

Objective: To investigate the changes in serum ghrelin and leptin levels in patients with clomiphene-resistant polycystic ovary syndrome (PCOS). Materials and Methods: Thirty-five patients who could not achieve ovulation or pregnancy despite using 150 mg/day of clomiphene citrate (CC) participated in the study. Thirty-five patients who were compatible with the study group in terms of age and body mass index (BMI) but did not have clinical and laboratory findings of PCOS constituted the control group. On the third day of the cycle, in addition to the basal hormone profile, ghrelin and leptin levels were also measured. Patients in both groups went to IVF/ICSI. Basal hormone values, leptin, ghrelin, metabolic, demographic parameters, and clinical pregnancy rates were correlated. Results: Patients in both groups were recorded to be similar in terms of age (29.4±0.11 vs 28.5±7.30), BMI (24.3±3.07 vs 23.8±1.55), and infertility time (6.14±4.30 vs 6.03±1.28). Serum ghrelin levels of the PCOS group were significantly lower than the control group (0.48±2.21 vs 1.19±4.02) Serum leptin levels of the PCOS group were significantly higher than the control patients (45.6±304 vs 16.5±0.32). Serum leptin levels and BMI (r=0.65, p<0.01) A positive correlation was found between luteinizing hormone (LH) (r=0.53, p<0.02), and insulin resistance (r=0.74, p<0.03). There was a negative (r=-0.76, p<0.03) correlation between serum ghrelin and LH. A positive and significant correlation was found between serum ghrelin, testosterone, mature oocyte, and implantation rates. Conclusion: Serum ghrelin correlates with fertility outcomes in women with CC-resistant PCOS undergoing IVF/ICSI.
