Regardless of the anatomical locations, some benign gynecological disorders (BGDs) such as peritoneal endometriosis, ovarian endometrioma, adenomyosis, uterine leiomyomas, endometrial polyps, uterine septum, and hydrosalpinges may lead to implantation failure. Despite progress in medical therapies, surgery remains a mainstay of BGDs treatment. Although our knowledge of endometrial receptivity after BGDs surgery is limited, it has allowed for significant improvement in the treatment of female subfertility. Many researchers studied on pregnancy outcome following BGDs surgery, but they did not investigate the possible impact of surgery on endometrial receptivity. They, therefore, concluded that pregnancy rates improved after BGDs surgery based on clinical observations. Many of these clinicians believe that surgical resection of BGDs leads to removal of local mechanical effect over the endometrium. Moreover, they accept that BGDs surgery may inhibit the detrimental signaling and secretion of some molecules from the BGDSs into the endometrium that may lead to favorable effect on the endometrium. However, so far, data from randomized controlled trials or systematic review or meta-analyses to answer the question whether surgical treatment of BGDs can improve endometrial receptivity are lacking. The purpose of this systematic review was to evaluate the results of available publications dealing with the impact of reproductive surgery for BGDs on endometrial receptivity.Regardless of the anatomical locations, some benign gynecological disorders (BGDs) such as peritoneal endometriosis, ovarian endometrioma, adenomyosis, uterine leiomyomas, endometrial polyps, uterine septum, and hydrosalpinges may lead to implantation failure.

OBJECTIVE To determine whether natural killer cell (NK) concentrations in the mid-secretory endometrial tissue of women with unexplained infertility differ from those in the mid-secretory endometrial tissue of fertile women. METHODS This study was conducted with 22 patients with unexplained infertility caused by unsuccessful ovulation induced with gonadotrophins and 12 healthy fertile women, who formed a control group. Mid-secretory endometrial tissue samples were obtained with a Pipelle catheter, and the endometrial NK cell phenotypes were determined by flow cytometry. RESULTS The median number of CD4+ cells in the endometrium was significantly lower in women with unexplained infertility compared with in the fertile controls (3.31 vs. 5.81; p=0.02). The CD4(+)/CD8(+) cell ratio in the unexplained-infertility group was significantly lower than that in the control group (0.42 vs. 0.76, p=0.01). The median number of CD103(+) cells in the endometrium of the infertile group was significantly lower than that in the endometrium of the control group (4.40 vs. 6.73, p=0.02). The median number of CD16(+) cells was significantly higher in infertile women than in control women (0.12 vs. 0.001, p=0.01). CONCLUSIONS Significant reductions in the numbers of CD4(+) and CD103(+) cells as well as in the CD4(+)/CD8(+) ratio but an increased number of CD16(+) cells in the endometrium of infertile women suggest that disordered NK cell activity may be a contributor to the etiology of unexplained infertility.

Objective: Aim of study to determine the existence of the G-spot from the healthy women’s point of view and to assess the relationship with sexual function and genital perception. Materials and Methods: Sexually-active healthy polyclinic patients aged between 18 and 54 years (n=309) were classified into three groups as group 1 (do not agree, n=90, 29.1%), group 2 (neutral/do not know, n=61, 19.7%) and group 3 (agree, n=158, 51.1%) with regard to participants’ responses to a question of “does the G-spot exist.” The Female Sexual Function index (FSFI) and Female Genital Self-Image scale (FGSIS) were administered to the participants. Results: Half of the patients (51.1%, n=151) indicated that the G-spot exists. The groups were statistically homogeneous in terms of body mass index, parity, marital status, number of partners, and sexual orientation (p=0.41, p=0.06, p=0.12, p=0.19, p=0.25; respectively). Women with an education level of “less than high school” reported the absence of the G-spot significantly more often than others, whereas women with an education level of “university and higher” reported the presence of the G-spot more often (p≤0.001). Sexual dysfunction was found to be more frequent in group 1 when compared with group 3 (p=0.002, 67.8%, 45.6%). The orgasm subdomain scores of the FSFI and FGSIS total scores were significantly higher in group 3 than in group 1 (p<0.001, p=0.041). Conclusion: Half of healthy women in the Turkish population believe that the G-spot exists. Those women showed better scores in sexual functioning and genital perception.

Introduction and hypothesisWomen’s perceived satisfaction from their own genital appearance is linked to genital image and sexual esteem. A comprehensive and easy to use scale to measure self-image was scarce in the literature. It was aimed in the present study to complement cross-culturally adapted and validated into Turkish version of the Female Genital Self-Image Scale (FGSIS) and to assess its psychometric properties.MethodsAfter cross-cultural adaptation, the Turkish version of the FGSI, Female Sexual Distress Scale-Revised (FSDS-R), and Female Sexual Function Index (FSFI) were administered to 461 female participants. Content/face validity, exploratory, and confirmatory factor analysis, internal consistency, and reliability were appropriately assessed. Predefined and specific hypotheses were formulated for construct validity.ResultsOur findings indicated excellent content/face validity, sufficient internal consistency (Cronbach’s alpha 0.818), and test–retest reliability [intraclass correlation coefficient (ICC) 0.951]. Construct validity was demonstrated by proving the hypothesis that participants who have performed at least one vaginal/clitoral masturbation for the last month reported significantly higher FGSIS scores compared with those who abstained (Z −6.37, p < 0.001). Factor analyses formed one factor structure. In the proposed two-factor construct, all seven items demonstrated good to high correlations with their subdomains and lower correlations with the other domain, indicating sufficient convergent validity.ConclusionsThe FGSIS was successfully validated for use in the Turkish population. The scale exhibited strong psychometric properties to assess perceived female genital image. It might be reliably used in genital cosmetic surgeries and in a variety of gynecologic conditions.

Objective Aim of the study was to assess the feasibility of a novel technique to determine the vascularity of labia minora prior to labiaplasty. Methods A cold light source employed in laparoscopic procedures was used to illuminate the outer surface of the labia minora as described in this prospective descriptive study. Results Of the patients, 46.1% (n = 41) had upper third prominence, 36% (n = 32) had middle third prominence, and 18% (n = 16) had lower third prominence according to the Banwell classification of morphologies. Right labia minora width was 0 – 2 cm in 51.7% (n = 46), 2 – 4 cm in 47.2% (n = 42) and > 4 cm in 1.1% (n = 1) of cases. Left labia minora width was 0 – 2 cm in 52.8% (n = 47), 2 – 4 cm in 41.6% (n = 37) and > 4 cm in 5.6% (n = 5) of cases. The incidence of Anterior 2 and Posterior 1 vessels in the different morphologies were statistically significantly different (p = 0.007, p = 0.018). The Anterior 2 vessel was higher in the lower morphology group whereas the Posterior 1 vessel was higher in the upper morphology group. A central vessel was observed in 93.3% (n = 83) of patients in the left labium minus and the right labium minus. The incidence of the Posterior 1 vessel was significantly higher in the left labium minus than in the right labium minus (p = 0.021). Discussion This novel technique to assess labial vascularity using a cold light source could be very useful to reduce dehiscence by avoiding excessive resection of highly vascularized tissue. Most units can easily access a cold light source, which can be used to assess labial vascularity prior to labiaplasty.

Purpose: We conducted this study to research both the forecasting efficiency of the cervical histogram and Bishop scoring for birth type (vaginal birth/cesarean) for the superannuated primigravida prior to birth induction. Methods: Ninety primigravidas in week 41 and beyond were included in the present study. Exclusions for the study included prior labor, ruptured membranes, any major uterine operations, cephalopelvic discord, fetal malpresentations, fetal anomalies, multiple pregnancy, placenta previa, vaginal bleeding, a high sensitivity for oxytocin usage, and an estimated fetal weight greater than 4000 g. Histogram hyperechogenic focus and hypoechogenic focus measurements are conducted in normal spontaneous birth (NSD) and cesarean (SECTIO) groups. Findings: Thirty-six patients had a cesarean birth, while 54 of the patients had vaginal births. On logarithmical regression analysis, the Bishop score and the parameters were found statistically significant in terms of proving the cesarean indication (p=0.001). In our cervical histogram, the forecasting efficiency of the hyperechogenic focus and hypoechogenic focus measurements for determining the birth type were not been able to shown (p=0.089 ; p=0.555). Bishop scoring parameters showed statistically significant deviances between the NSD group compared to the cesarean group in terms of a 1-2 cm increase in cervical opening and for being 3-4 cm(p=0.0001), the cervical extinguishment as 40%-50% (p=0.0001), the occurrence of cervical softening (p=0.0001), and the head level at -1 and -2 (p=0.0001). When declaring the cesarean indication, the Bishop score’s AUC value was found as 0.932 and the LR(+) value as 9; while the estimation value for the Bishop score occurring below <5 increased the cesarean birth risk ninefold. Conclusion: During a superannuated nulliparous pregnancy, the Bishop score and the Bishop score’s individual parameters are meaningful for vaginal birth, while a cervical histogram is not significant for forecasting the

Introduction: Intracytoplasmic sperm injection (ICSI) currently helps many couples with male infertility. However, ICSI procedure may cause asynchronous sperm decondensation. This could introduce a risk for aneuploidy. The ICSI technique also could cause damage to the second meiotic spindle during injection and cause significantly abnormal pairing of chromosomes when compared with In vitro fertilization (IVF). In this study, we have examined whether ICSI has a higher incidence of aneuploidy when compared with IVF. Material and Methods: A retrospective study was conducted on 36 individuals. Common numbers of chromosome abnormalities were detected using fluorescent in-situ hybridization (FISH). Seven probes were used to detect chromosome X, Y, 13, 16, 18, 21, and 22. Chi-square test was used for statistical analysis and presented as odd ratios with confidence intervals. Results: The age range was 26 through 44 (mean age 35.5) for IVF and 25 through 46 (mean age 35.8) for ICSI. From the 36 egg retrievals, 57 embryos were obtained from nine individuals using IVF and 183 embryos were obtained from 27 individuals using ICSI. For the IVF group, 37 of the 57 examined embryos were abnormal (65%), whereas 128 of 183 examined embryos were abnormal for the ICSI group (69.9%). Among the 57 embryos from the IVF cases, the number of absolute abnormal chromosomes were as follows: X&Y chromosomes: 4 (12.9%), chromosome 13: 9 (29%), chromosome 16: 7 (22.5%), chromosome 18: 6 (19.3%), chromosome 21: 8 (25.8%), chromosome 22: 10 (32.2%). For the ICSI embryos: X and Y chromosomes: 18 (14%), chromosome 13: 34 (26.5%), chromosome 16: 23 (18%), chromosome 18: 23 (18%), chromosome 21: 26 (20.3%), chromosome 22: 31 (24.2%). The odds ratios for the difference between IVF and ICSI for each chromosome were as follows: X&Y chromosomes: 1.53 (0.598-3.916), chromosome 13: 0.969 (0.443-2.122), chromosome 16: 0.709 (0.307-1.639), chromosome 18: 1.650 (0.650-4.188), chromosome 21: 0.777 (0.350-1.724), chromosome 22: 0.647 (0.311-1.348). Overall no significant difference between two insemination procedures was seen 0.948 (0.678-1.324). Conclusions: As a result; ICSI does not create a significantly higher aneuploidy number when compared with IVF as examined by FISH analysis of seven chromosome pairs.

Abstract This study was planned to investigate whether measuring of Doppler indices with TV-DUS improved the diagnosis of adenomyosis. Preoperative Doppler indices of subjects with a preliminary diagnosis of adenomyosis were compared with the histopathological results of excised specimens. Sensitivity, specificity and positive/negative predictive values (PPV, NPV) of the measured indices were also calculated. Sensitivity, specificity, PPV and NPV and positive and negative likelihood ratios (LR+) and (LR−) of TV-US in the diagnosis of adenomyosis were found to be 70.8%, 62.1%, 40.4%, 85.4%, 1.96 and 0.47, respectively. Sensitivity, specificity, PPV, NPV, LR + and LR − in the diagnosis of adenomyosis following the addition of TV-DUS were found to be 90%, 94.2%, 81.8%, 97%, 15.5 and 0.10, respectively. Concomitant use of TV-US and TV-DUS improved correct diagnosis of adenomyosis with high sensitivity.
