Abstract Background The aim of this study was to evaluate the effectiveness of current ovarian reserve tests in unexplained infertile cases. Material and methods This case–control study was conducted on 70 unexplained infertile women who were included in a tertiary university hospital. Both groups of basal FSH, estradiol, antimullerian hormone (AMH), inhibin B, ovarian volume, total antral follicle count (AFC), ovarian volume, and ovarian stromal blood flow (peak systolic velocity (PSV), S/D (systole and diastole ratio), resistance index (RI), and pulsatility index (PI)) values were compared. Results The mean AMH, inhibin B, PSV, and stromal blood flow values of the control group patients were higher than those in the unexplained infertility group. However, the values of the means of RI and PI of the cases in the control group were lower than those in the infertility group. When PI’s value was ≥ 2.00, its sensitivity was 65.7%, and its specificity was 64.3%. In the case of the RI, its value was ≥ 0.745, its sensitivity was 65.7%, and its specificity was 62.9%. In order to show ovarian reserve in unexplained infertile cases, the sensitivity values can be sorted from high to low as follows: PI > RI > estradiol > FSH > ovarian volume > AFC > inhibin B > stromal blood flow > PSV > S/D. Conclusion In the unexplained infertile patient group with normal ovarian reserve test results, basal estradiol, decreased PI, and RI values may be used as good ovarian reserve predictors.

AIM
To examine the structural and functional changes of the fetal heart in gestational diabetes mellitus (GDM) and to evaluate the power of fetal cardiac Doppler parameters in predicting adverse perinatal outcomes in this group of pregnancy.
METHODS
Within the study's scope, 36 cases in the A1 GDM group, 33 cases in the A2 GDM group, and 124 cases in the control group were evaluated. The relationship between structural and functional fetal cardiac parameters and perinatal outcomes was evaluated via fetal echocardiography.
RESULTS
Fetal left ventricular myocardial performance index (MPI) values were found to be statistically significantly higher when compared between the A1 GDM and A2 GDM groups and the control group (p = 0.000 and p = 0.000, respectively), while the E/A ratio was found to be significantly lower (p = 0.000 and p = 0.000, respectively). It was determined that the maternal blood HbA1c level showed a significant negative correlation with the fetal cardiac E/A ratio and a significant positive correlation with isovolumetric relaxation time and MPI (p = 0.000, p = 0.000, and p = 0.000, respectively). Adverse perinatal outcome rate was higher in the diabetic group (46.4%-22.6%). When the cases with GDM were examined in terms of perinatal outcomes, it was observed that there was a significant difference in HbA1c levels, E/A ratio, and MPI values between the cases in the group with adverse perinatal outcomes and the group with normal results (p = 0.001, p = 0.000, and p = 0.000, respectively).
CONCLUSIONS
The strong relationship between abnormal cardiac function and adverse perinatal outcomes suggest that cardiac Doppler may be a valuable tool for fetal monitoring and management for the GDM patient group.

Background: The aim of this study was to compare fetal thymus volume in women who delivered at <36 weeks of pregnancy versus those who did not. Methods: A total of 32 dichorionic-diamniotic twin pregnantwomenwere included in the prospective cohort study. The fetal thymus volumesweremeasured in the second trimester for each fetus using the VOCAL ultrasonography program. The data of women who experienced preterm labor (delivered at<36 weeks of pregnancy) and the control group (delivered at≥36 weeks of pregnancy)were compared. Results: Themean thymus volumeof each fetuswas statistically significantly lower in pretermdelivery cases than in the control group. Mean fetal thymus volume could be used as a marker for predicting preterm birth in the study group. The parameter of fetal thymus volume measured in twins at 18–24 weeks can be used as a predictive factor (P < 0.001). When the fetal thymus volume, measured 3-dimensionally by ultrasonography in conjunction with the VOCAL program, was used as amarker for predicting preterm delivery, the cut-o f value was found to be 0.5245 cm, with 83.3% sensitivity and 85.8% specificity (AUC 0.905, P< 0.001, 95% CI, 0.798–0.930). Conclusion: By predicting preterm delivery via measuring the fetal thymus volume in twins, physicians can suggest strategies to prevent preterm delivery at 18–24 weeks of pregnancy. In thisway, fetalmortality/morbidity related topretermdeliverymay be prevented.

Objective: The aim of this study was to evaluate ovarian immunohistochemical CD95 expression in a rabbit carbon dioxide pneumoperitoneum model. Materials and Methods: The study group including seven rabbits was subjected to intra-abdominal pressure (IAP) (12 mmHg); the control group was not subjected to IAP (the sham group, n = 7). At the end of the experiment, ovariectomy was performed. Immunohistochemical stained histologic specimen of the ovary with CD95 was evaluated. Based on the degree of cytoplasmic or membranous staining for CD95 from 0 (none) to 3 (severe), a microscopic apoptosis scoring system was used. Results: Statistically significantly higher apoptosis scores in ovarian surface epithelial cells (2.57 ± 0.53, vs. 1.14 ± 0.38, P = 0.002, Mann–Whitney U-test, respectively), follicular epithelial cells (2.85 ± 0.38, vs. 1.85 ± 0.38, P = 0.002, Mann–Whitney U-test, respectively), and stromal cells (2.71 ± 0.49, vs. 1.29 ± 0.49, P = 0.002, Mann–Whitney U-test, respectively) were observed in pneumoperitoneum group, compared with no-pneumoperitoneum group. Conclusion: Even at safe IAP (12 mmHg) for an acceptable operation time period, there was a significant increase in apoptosis of ovarian cells.

Introduction To assess the effect of low-dose combined oestradiol and norethindrone acetate hormone therapy (HT) on serum C-reactive protein (CRP) levels and life quality in natural menopause women. Material and methods Forty-five natural menopause women admitted to the clinic during a 1-year period and diagnosed as menopause, who planned to have HT for menopausal symptoms, were enrolled in this prospective study. The serum CRP levels were measured, and vasomotor symptoms scores were graded according to the Blatt-Kupperman menopause index, and life quality scores according to the Menopause-Specific Quality of Life Questionnaire (MENQOL) were recorded before and after (3 months later) hormone therapy. Results The Blatt-Kupperman menopause index and MENQOL scores were significantly decreased after 3 months of low-dose treatment. No significant difference was found between white blood cell counts and serum CRP levels before and after 3 months of hormone therapy. Conclusions Considering all HT types and biochemical effects, low-dose HT, which had positive results in terms of quality of life, was a safe treatment and could be preferred to conventional-dose preparations in cases without contraindications. Low-dose combined HT containing oestradiol and norethindrone acetate did not alter the serum CRP level in postmenopausal cases.

Introduction To assess the effect of hormone therapy (HT) on serum ischemia modified albumin (IMA) levels in healthy menopausal women. Material and methods Thirty surgical menopausal women who were admitted to our menopausal polyclinic during a 1-year period and diagnosed with menopause and planned to have HT for menopausal symptoms were enrolled in this prospective study. The serum İMA levels were recorded before and after (3 months, 6 months, 12 months later) hormone treatment (2 mg estradiol hemihydrate). Results The mean age of women was 47.60 ± 2.34 years. The mean serum IMA levels were 0.610 ± 0.096 absorbance units (ABSU) at the beginning and 0.484 ± 0.080 ABSU after 3 months of hormone therapy. Following 6 months of hormone therapy, serum IMA level was 0.546 ± 0.075, and reached 0.580 ± 0.089 ABSU following 12 months of therapy. Conclusions These findings suggest that HT may not block the menopause induced ischemia process. Although HT had a positive effect on serum IMA levels following 3 months’ use, serum IMA levels returned to baseline levels after 12 months’ use. Based on this study’s findings, long-term use of HT may not have a positive effect on cardiovascular disease protection.

Abstract This study aimed to examine whether the menstrual cycles of women with regular cycles have been affected by the COVID 19 pandemic. This cross-sectional online survey study evaluated the menstrual cycle characteristics of women in the reproductive phase of their lives during the COVID-19 pandemic in May 2020. Changes before and after COVID-19 were evaluated with a paired sample t-test and chi-square test. A Pearson correlation test was used to show the relationships between variables. The study was completed with 263 participants in total. The average age of the participants was 26.3 ± 6.9 (18–45). Participants’ duration of period (p = .003) and pads used per day (p = .002) decreased compared to their experience before the COVID-19 outbreak. The mean total MSQ score was 3.1 ± 0.8 (0–4), mean STAI-1 score was 45.1 ± 9 (20–78) and mean STAI-II score was 43.3 ± 5.9 (30–69). It was found that STAI-I and STAI-II scores showed a positive correlation with MSQ-Somatic subgroup scores(r = 0.153, p = .013; 0.190, p = .002) and MSQ-Total scores (0.144, p = .020; 0.175, p = .004). With the COVID-19 pandemic, increased anxiety scores increased women's menstrual symptoms while the length of periods and the number of pads used decreased. Impact statement What is already known on this subject? The COVID 19 pandemic, has caused enormous psychological distress potentially resulting in the development of posttraumatic stress disorder. The menstrual cycle is a process that can be affected by psychological stress. What do the results of this study add? This is the first study to examine the relationship between stress caused by the COVID-19 pandemic and the menstrual cycle. The increases in the degree of anxiety and stress as a result of the COVID-19 outbreak was found to be high enough to affect the characteristics of the menstrual cycle in the women surveyed. What are the implications of these findings for clinical practice and/or further research? In a prospective study intended to be carried out after the outbreak ends in the future, it will be possible to evaluate whether the menstrual cycle parameters return to their former order and consequently this hypothesis will be able to be more definitively confirmed.

In this prospective study, the aim was to determine the frequency and effectiveness of the coitus interruptus method, to compare the demographic characteristics of women using modern contraception methods and those using the coitus interruptus method and to demonstrate how effective contraceptive counselling is in choosing a contraception method. The researchers collected data from 1000 sexually active women in their reproductive period at the gynaecological clinic of a university hospital in Turkey. The researchers used an introductory information contraceptive counselling form, which they prepared for the data collection tool. The rate of the coitus interruptus method use among the interviewed women was 42.8%. There was a statistically significant difference between the coitus interruptus group and the group using modern contraceptive methods regarding mean age, educational status, smoking, awareness of last menstrual period, number of pads used during the menstrual period, and information sources. Following effective contraception counselling, the rate of switching to a modern and proven contraceptive method was found to be 73.8%.Impact statementWhat is already known on this subject? Although the traditional method of coitus interruptus has been used for many years, its incidence is not clearly known. What we know about the subject is based on ancient research. All the studies on the subject are very old and need to be updated.What do the results of this study add? With the help of the data obtained from this study, it is understood that withdrawal method is still widely used today, it is still not known that it is not a modern contraceptive method and the rate of transition to modern methods with effective contraception counselling is very high.What are the implications of these findings for clinical practice and/or further research? In the outpatient clinic conditions, even a very short period of time for contraception counselling will be very beneficial for women and will contribute to family planning and prevent unwanted pregnancies.

Introduction Many postmenopausal women experience hot flashes, night sweats, decreased sexual desire and vaginal dryness. In this study, we aimed to compare the menopause symptom levels of surgical menopause patients and natural menopause patients by using a Menopause Rating Scale (MRS) and investigate whether there is a relationship between lipid levels and menopausal symptoms in surgical menopause patients. Material and methods This cross-sectional study was conducted on postmenopausal women who applied to the gynecology outpatient clinic. A total of 187 patients were analyzed. Of these,112 were the surgical menopause group and the remaining 75 were the natural menopause group. Total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol and triglycerides were measured by using an enzymatic color test. In order to evaluate the postmenopausal symptoms of postmenopausal women included in the study, the MRS questionnaire adapted to the Turkish population was used. Results Considering the results of the MRS of the two groups, the results of surgical menopause patients were found to be statistically significantly higher. The results were statistically significantly higher in both the total score and in the two subgroups(somatic and psychological subgroups)in the surgical menopause group. When the MRS results(subgroups and total score)of women in the surgical menopause group were classified as mild and severe, no statistically significant relationship was found between symptom severity and blood lipid levels. Conclusions In the surgically induced menopause group, it was shown by this study that menopausal symptoms were more severe than the natural menopause group. Unlike natural menopausal patients, no relationship was found between lipid levels and severity of menopausal symptoms in surgical menopausal patients.
