Objective. To evaluate whether a change takes place in antimullerian hormone (AMH) levels reflecting the ovarian reserve after laparoscopic endometrioma stripping surgery and to demonstrate if there is any correlation between AMH levels and the sizes of endometriomas. Method. Fourty-seven women participated as the study group in this prospective controlled trial, 33 of whom (70.2%) had unilateral and 14 (29.7%) of whom had bilateral endometriomas. Pre- and post-operative serum AMH levels were measured and compared with 17 normo-ovulatory control cases and also correlated with endometrioma sizes. Result(s). Mean pre-operative AMH levels of the study group and the normo-ovulatory control cases did not reveal a statistically significant difference (1.62 ± 1.09 ng/ml and 2.06 ± 0.51 ng/ml, P > 0.05). Mean level of post-operative serum AMH of the study group decreased from 1.62 ± 1.09 to 1.39 ± 1.16. However, this reduction was not statistically significant. (P > 0.05). Pre- and post-operative AMH levels do not reveal a correlation with the size of endometrioma in both group of patients with either unilateral or bilateral endometrioma. Conclusion(s). The presence of the endometrioma does not impair the AMH levels. Laparoscopic endometrioma stripping surgery do not appear to cause a damage in the AMH secreting healthy ovarian tissue, in the short-term follow-up. Laparoscopic stripping surgery of endometriomas in experienced hands is currently a valid approach.

OBJECTIVE To evaluate the ovarian reserve after laparoscopic stripping of unilateral endometriomas by comparing the operated and non-operated ovaries. STUDY DESIGN Bilateral ovarian volumes, antral follicle counts, and stromal blood flows were assessed by ultrasonography and anti-mullerian hormone (AMH) levels were analysed in 36 patients who had undergone laparoscopic cystectomy for unilateral ovarian endometrioma. RESULTS Mean antral follicle counts (AFC) of the operated side ovaries were significantly lower on the second postoperative day (3.1 ± 2.4 vs 5.2 ± 3.7; p<0.05) and in the third month (3.7 ± 2.1 vs 6.4 ± 2.7; p<0.05). Pulsatility indices of the operated ovaries were significantly decreased on the second postoperative day (2.22 ± 0.46 vs 1.76 ± 0.51; p<0.05) while resistance indices were increased (0.81 ± 0.06 vs 0.88 ± 0.13; p<0.05). Doppler parameters had recovered and a non-significant decrease in AMH levels of the patients was recorded in the third month after surgery (2.03 ± 0.41 ng/mL vs 1.95 ± 0.62 ng/mL; p>0.05). CONCLUSION Although laparoscopic stripping of endometriomas seems to affect the ovarian reserve in terms of AFCs, it does not have a significant negative impact at the end of three months as assessed by ovarian volumes, Doppler indices and AMH levels. Endometrioma surgery techniques are important in preserving normal functioning ovaries and further studies are necessary for optimising these surgical approaches.

OBJECTIVE To examine the impact of type of infertility on female sexual function. DESIGN Comparison of female sexual function index and prevalence in primary infertile women and secondary infertile women. SETTING Hospital. PATIENT(S) One hundred twenty-two primary infertile and 51 secondary infertile women. INTERVENTION(S) Questionnaires (Female Sexual Function Index [FSFI] and Beck Depression Inventory). MAIN OUTCOME MEASURE(S) Prevalence of dysfunction in primary and secondary infertile women. RESULT(S) The prevalence of female sexual dysfunction was 64.8% (n = 79) and 76.5% (n = 39) in primary infertile and secondary infertile women, respectively. In analyses of mean overall and subgroup scores of FSFI, there were significant differences between primary and secondary infertile women in the mean scores of orgasm, satisfaction, and total FSFI. Backward logistic regression identified a model with four significant predictors of sexual dysfunction (group, age, income level, and educational level). Secondary infertile women had a 9.5-fold higher risk of sexual dysfunction than primary infertile women after adjustment for confounding factors. CONCLUSION(S) There was a higher prevalence of sexual dysfunction in secondary infertile women. Secondary infertile women have decreased sexual desire, orgasm, and satisfaction compared with primary infertile women.

OBJECTIVE Urinary incontinence (UI) may affect a womans physical and psychological well-being in different aspects. The aim of this study was to compare the effects of urinary stress incontinence (USI), detrusor overactivity (DO) and mixed urinary incontinence (MUI) on sexual function. STUDY DESIGN One-hundred and seventy urinary incontinent, sexually active women were included in this cross-sectional study. After urodynamic evaluation, participants were divided into three subgroups as USI (n=61), DO (n=55) and MUI (n=54). Patients were matched according to age, parity and body mass index (BMI), rendering the sample size to 41 patients in each group. Turkish version short form of the Pelvic Organ Prolapse/Incontinence Sexual Function Questionnaire (PISQ-12) was filled out by each of the participants. Totally, 52 patients were excluded from the study (47 could not be matched and 5 incomplete questionnaire). Demographic characteristics of the participants, total and three domain scores of PISQ-12 were compared among three UI subgroups. RESULTS The study group was consisted of 38 (32.2%) DO, 41 (34.7%) USI and 39 (33.1%) MUI patients. Demographic characteristics of the patients were similar in three subgroups. Patients with a diagnosis of MUI had significantly lower mean PISQ-12 scores than the ones with USI and DO whereas patients with USI had lower mean PISQ-12 scores than patients with DO. CONCLUSION Although urinary stress incontinence effects sexual function more than detrusor overactivity in terms of PISQ-12 scores, mixed urinary incontinence has the greatest impact on sexual function when compared with urinary stress incontinence and detrusor overactivity.

Objective. Anti-muscarinic treatment alone and peripheral neuromodulation with concomitant anti-muscarinic treatment were compared in patients with severe overactive bladder. Methods. In this prospective study, 40 women with severe overactive bladder according to the 7-day voiding diary without any prior treatment completed the Incontinence Impact Questionnaire (IIQ-7) and were randomised into anti-muscarinic-alone and combination treatment groups. Twenty women received daily 4 mgs of tolterodine orally and in 20 women Stoller afferent neuro-stimulation (SANS) therapy was performed concomitantly for 12 weeks to the same anti-muscarinic regimen. After 12 weeks of therapy, two of the patients drop out of the study and remaining patients filled out the IIQ-7 questionnaire and the 7-day voiding diary again. Pretreatment and post-treatment QoL scores and the 7-day voiding diaries were compared. Mann–Whitney U, Wilcoxon and two sided significance tests were used. Results. Thirty-eight women fulfilling the criteria were included in the study. Severity of overactive bladder symptoms decreased significantly in both treatment groups. However, the decrease in combination treatment group was more significant than the anti-muscarinic-alone group. Adverse events were similar between the two groups. Conclusion. Combining SANS and anti-muscarinic therapy resulted in significantly better clinical outcomes and IIQ-7 scores as compared with anti-muscarinic treatment alone in patients with severe overactive bladder.

Pelvic and abdominal pain is especially common in adolescent age group. Differential diagnosis could be gastrointestinal, renal, gynecological, and psychosomatic causes. The inability to pass urine, which is termed as acute urinary retention (AUR), is an uncommon cause of pelvic pain. The etiology of AUR is age dependent; and in childhood, severe voiding dysfunction may be drug induced with antihistamines or anticholinergic drugs, psychogenic, related to viral infections, congenital anomalies, neurological bladders, or mechanical compression of the urethra via the mass of pelvis [1,2]. Hematocolpos is defined as the accumulation of menstrual blood in the vagina instead of its expulsion, which is usually because of an imperforate hymen. The incidence of imperforate hymen as a congenital obstructive abnormality of the female genital tract is 1:2,000 [3]. We report a case of an adolescent girl who complained of pelvic pain resulting from AUR because of an imperforate hymen, which also mimicked pelvic mass at the differential diagnosis. A 15-year-old girl referred to our tertiary center obstetrics and gynecology department from emergency service with the symptoms of acute severe lower abdominal pain and inability to pass urine. The tentative diagnosis in emergency service was a semisolid pelvic mass measuring about 12 7 9 cm diagnosed by transabdominal ultrasonography. Gynecological examination was not performed at the emergency service; instead, the patient was referred to the obstetrics and gynecology department of our hospital. At the admission of the patient, she seemed very uncomfortable and was cramping with an intermittent pelvic pain. Her temperature was 37 C, pulse rate was 90/min, respiration rate was 18/min, and the blood pressure was 110/78 mmHg. Her personal and family history revealed nothing unusual except the

Polycystic ovary syndrome (PCOS) is one of the most common reproductive endocrinopathy and a major cause of infertility. PCOS may be associated with chronic anovulation and endometrial hyperplasia. Conservative treatment should be considered in young women wishing to preserve their fertility. Standard treatment for complex endometrial hyperplasia is the use of high-dose progesterone, whereas we preferred levonorgestrel-releasing intrauterine system (LNG-IUS) as a last resort in our patient who was resistant to oral gestagens. We present a case with complex atypical endometrial hyperplasia treated conservatively in a long-term period first by oral gestagens, then by LNG-IUS. In our case, LNG-IUS was more effective than oral systemic progestins, not only for reducing the menstrual blood loss but also for improving the pathological findings. After extraction of LNG-IUS rapid achievement of pregnancy was carried out by intracytoplasmic sperm injection and embryo transfer and she took home twin babies. To the best of our knowledge, this is the first successful twin pregnancy case with ICSI and ET in a patient with oral gestagen resistant endometrial complex/atypical hyperplasia achieved after application of LNG-IUS. In complex atypical hyperplasia, LNG-IUS should be kept in mind as an effective alternative treatment modality before assisted reproductive technology (ART).

OBJECTIVE To present our in vitro fertilization outcomes after implementation of the Turkish government policy limiting the number of transferred embryos to one, in women under the age of 35, and two, in women over age 35; and to demonstrate the feasibility of this policy. STUDY DESIGN We retrospectively reviewed the records of 423 patients who underwent ovarian stimulation, oocyte pick-up, intracytoplasmic sperm injection and embryo transfer due to primary or secondary infertility over a 22-month time interval. Clinical pregnancy was defined as a fetal heartbeat in the seventh gestational week. Embryo transfers were carried out on day 3 or 5. Descriptive statistics are given as the number of subjects and percentages. RESULTS A total of 353 embryo transfers were performed: 261 (73.9%) were single-embryo transfer (244 (69.1%) elective and 17 (4.8%) non-elective) and 92 (26.1%) were double-embryo transfer. Of the 244 elective single-embryo transfers, 6.6% (n=16) were performed using frozen-thawed embryos. The average patient age was 29.6±4.5 years in the single-embryo group and 36.5±2.4 years in the double-embryo group. The cumulative pregnancy rates per oocyte pick-up were similar in both groups: 41% (n=107) in the single-embryo group and 43.4% (n=40) in the double-embryo group (p=0.678). The cumulative live birth rate of the single-embryo group (32.1%) was not statistically different from the double-embryo group (35.8%) (p=0.518). The twin pregnancy rate after single-embro transfer was significantly lower than with double-embryo transfer (2.8% (n=3) vs. 32.5% (n=13); p<0.001) and 62.5% of the twin pregnancies occurred in women 35 years or older who underwent double-embryo transfer. No significant difference in the spontaneous abortion rates was recorded between the single- and double-embryo transfer groups (16 (6.1%) vs. 6 (6.5%); p=0.894). CONCLUSION Single-embryo transfer results in a pregnancy rate comparable to double-embryo transfer, with a significantly reduced multiple pregnancy rate. Double-embryo transfer in patients over age 35 should be reconsidered because of the resulting high rate of multiple pregnancy.

ObjectiveThe aim of this study was to determine whether quantitative PolScope characteristics of meiotic spindle and zona pellucida could be used as a non-invasive marker to predict implantation success in elective single embryo transfer cycles.MethodsQuantitative birefringence parameters; including mean retardance, area, length and polar body deviation angle of meiotic spindle and mean retardance and width of inner zona pellucida belonging to 53 transfer oocytes from elective single embryo transfer cycles were retrospectively analyzed. The relevant PolScope features were compared between 20 conception and 33 non-conception cycles.ResultsMeiotic spindle mean retardance, area, length and inner zona pellucida mean retardance and width did not reveal a statistically significant difference between transfer oocytes from conception and non-conception cycles. Deviation angle of the polar bodies was also comparable between the groups. Spindle and inner zona PolScope characteristics of transfer oocytes were not correlated with the maternal age.ConclusionQuantitative PolScope features of meiotic spindle and inner zona pellucida can not be used as a non-invasive marker to predict assisted reproductive technology success in elective single embryo transfer cycles.

OBJECTIVE To find out whether tubal sterilization leads to loss of ovarian reserve, we assessed the hormonal and ultrasonographic parameters of ovarian reserve in women who underwent laparoscopic tubal sterilization by bipolar electrodesiccation and transection. STUDY DESIGN In this preliminary study, laparoscopic tubal sterilization was performed on 49 healthy women who had voluntarily requested elective surgical sterilization. Among the current ovarian reserve indicators, in the early proliferative phases, preoperative (baseline) and postoperative (third month) serum follicle-stimulating hormone (FSH), estradiol (E2), and anti-Mullerian hormone (AMH) levels, ovarian volume, and antral follicle counts (AFCs) were determined. Analysis of these hormonal and ultrasonographic parameters of ovarian reserve preoperatively and postoperatively was the main outcome measure. RESULTS Preoperative and third-month postoperative FSH, LH, E2, and AMH levels did not reveal statistically significant differences (p=0.101, p=0.180, p=0.254, and p=0.079; respectively). The ultrasonographic indicators of ovarian reserve did not change in terms of total ovarian volume and total AFC (p=0.793 and p=0.098, respectively). CONCLUSIONS Short-term follow-up study results revealed a slight but non-significant change in the current ovarian reserve markers, especially in the AMH levels.
