The effect of the birth method on changes of the prepartum and postpartum dimensions of perineal body.

OBJECTIVE: The perineal body is critical for maintaining the integrity of the pelvic floor, especially in females as it can be injured during vaginal delivery. This study aimed to evaluate the effect of childbirth on perineal body dimensions by using a transperineal 2D ultrasound. STUDY DESIGN: This prospective cohort study was performed in a tertiary obstetric care center. A total of 172 term pregnant women who delivered either by cesarean section or vaginal delivery were enrolled in the study. All demographic data and information were collected prospectively. The perineal body was measured in length, height, perimeter, and area. Mode of delivery was classified into four categories, including prelabor cesarean section, cesarean section during the first stage of labor, the first vaginal delivery, and more than one previously vaginal delivery. A postpartum evaluation was performed after 6 weeks. RESULTS: Among the 172 women, 40 (23.3 %) had a history of cesarean section (CS) and they delivered with scheduled CS, 40 (23.3 %) women delivered by primary CS during active labor, 48 (27.9 %) women had the first vaginal delivery, 44 (25.6 %) women who delivered vaginally had a history of at least one vaginal delivery. The postpartum perineal body measurements were significantly lower in terms of length, perimeter, and area in all pregnancy groups. CONCLUSION: Pregnancy and delivery change perineal body dimensions, significantly. Cesarean section does not completely protect against changes in perineal body morphology.

Do follicular fluid advanced glycation end products levels affect the ovarian response in unexplained infertility?

OBJECTIVE: To compare the advanced glycation end products (AGEs) levels in follicular fluid according to the different ovarian responses of women who underwent controlled ovarian stimulation due to unexplained infertility and to examine the relationship between these levels and pregnancy outcomes. METHODS: Sixty-three women who underwent fresh IVF/ICSI cycles with GNRH antagonist protocol were divided into 3 groups according to the number of retrieved oocytes as suboptimal (4-9 oocytes), optimal (10-15 oocytes) and high (>15 oocytes) responders. AGEs levels in follicular fluid were measured by ELISA method. RESULTS: AGEs levels were 6.81 ± 2.20 µg/ml, 5.30 ± 2.01 and 6.44 ± 1.43 µg/ml in suboptimal, optimal and high response group, respectively. AGEs level was significantly higher in suboptimal response group than in optimal response group. The cutoff level of 6.19 µg/ml had a sensitivity of 59.3% and a specificity of 66.7% in distinguishing the suboptimal response group from the optimal response group. However, there were no statistically significant difference between AGEs levels and clinical pregnancy and live birth rates. CONCLUSION: Increased AGEs level in follicular fluid may be associated with decreased ovarian response during controlled ovarian stimulation in unexplained infertility case, however, it does not provide information about pregnancy outcomes.

Effect of time intervals from the end of sperm collection to intrauterine insemination on the pregnancy rates in controlled ovarian hyperstimulation-intrauterine insemination cycles.

OBJECTIVE: To analyze the effect of time intervals from the end of sperm collection to IUI on the pregnancy rates in couples who treated by COH-IUI cycles with gonadotropin due to unexplained infertility. METHODS: 556 couples who underwent the first COH-IUI treatment with gonadotopin due to unexplained infertility were included. Semen samples were obtained by masturbation in a private room near the laboratory on the day of insemination. For each semen samples, time between the delivery time to the laboratory and starting time of sperm washing procedure was noted as semen collection to sperm washing (SC-SW) interval, the time between the starting time of sperm washing procedure and insemination time was noted as sperm washing to insemination (SW-IUI) interval and the time between the delivery time to the laboratory and insemination was noted as semen collection to insemination (SC-IUI) interval. Clinical pregnancy was defined as positive pregnancy test followed by the presence of an intrauterine gestational sac with fetal cardiac activity by transvaginal ultrasonography at least 4 weeks after IUI. RESULTS: Among 556 couples, there were 84 cases of succesful clinical pregnancy and pregnancy rate was calculated as 15.1%. Intervals from SW to IUI and SC to IUI were significantly shorter in pregnant women than in non-pregnant (p<0.001 and p=0.007, respectively). SW performed ≤40min after SC resulted in higher clinical pregnancy rates than did SW performed >40min after SC (19.1% vs. 6.3%, respectively) (p<0.001). IUI performed ≤60min after the end of SW had higher pregnancy rates (16.9%) compared to IUI performed >60min after the end of SW (4.0%) (p=0.017). Likewise, IUI performed ≤90min after SC resulted in higher pregnancy rates than did IUI performed >90min after SC (18.9% vs. 12.0%, respectively) (p=0.029). CONCLUSION: IUI outcome is enhanced by shorter intervals from SC to SW, from SW to IUI, and from SC to IUI in gonadotropin-IUI cycles for unexplained infertile couples.

Risk factors for adenomyosis, leiomyoma and concurrent adenomyosis and leiomyoma.

AIM: To evaluate the risk factors for adenomyosis, leiomyoma and concomitant adenomyosis and leiomyoma in patients with treatment-resistant menometrorrhagia. METHODS: A retrospective study was conducted on 129 women who underwent abdominal hysterectomy for treatment-resistant menometrorrhagia. The patients were divided into four groups according to the postoperative histopathology: concomitant adenomyosis and leiomyoma (n = 33), adenomyosis only (n = 26), leiomyoma only (n = 48) and controls (n = 22). Patients without any organic uterine pathology constituted the control group. RESULTS: Age at menarche was higher in the concomitant adenomyosis and leiomyoma group compared to the adenomyosis only group (P = 0.006). The mean age (P = 0.007), age at menarche (P = 0.001) and gravidity (P = 0.001) were higher in the concomitant adenomyosis and leiomyoma group compared to the leiomyoma only group. Preoperative hemoglobin was lower in the concomitant adenomyosis and leiomyoma, adenomyosis only, and leiomyoma only groups than the control group (P < 0.008). On receiver operating characteristic analysis, hemoglobin <10.9 mg/dL had a sensitivity and specificity of 77% and 70%, respectively, in discrimination of any uterine organic pathology, including adenomyosis only, leiomyoma only, and concomitant adenomyosis and leiomyoma, from the control group. Patients in the adenomyosis group were older (OR, 1.20; 95%CI: 1.05-1.50) and had a lower age at menarche (OR, 0.42; 95%CI: 0.19-0.89) than the other groups. CONCLUSIONS: Preoperative anemia may be a useful predictor of adenomyosis. Older patients, and patients who had a lower age at menarche, were also more likely to have adenomyosis.
