RESUMEN
BACKGROUND: With increased success, ovarian tissue cryopreservation has recently become a standard technique for fertility preservation. However, malignant cell introduction through ovarian tissue transplantation remains a major concern for patients with acute leukemias. OBJECTIVE: This study aimed to investigate the safety of performing autologous ovarian tissue transplantation in survivors of acute leukemia. STUDY DESIGN: Clinical, histopathological, and molecular data of 4 women with acute myeloid leukemia and 2 women with acute lymphoblastic leukemia who underwent ovarian tissue cryopreservation and transplantation were analyzed in this case series. Following cryopreservation of 66% to 100% of an ovarian cortex with a slow freezing method, all women received high-dose multiagent alkylating preconditioning chemotherapy for allogeneic hematopoietic stem cell transplantation. Before the ovarian tissue transplantation, (1) antral follicle counts, serum antimüllerian hormone and follicle-stimulating hormone levels were assessed to confirm primary ovarian insufficiency; (2) all recipients were cleared by their hematologist-oncologists; (3) representative cortical strips were screened for leukemia infiltration by histologic (hematoxylin and eosin staining), immunohistochemical (CD3, CD20, CD34, CD68, CD117, CD163, PAX-5, Tdt, lysozyme, and MPO), and molecular marker evaluation (BCR/ABL p190 and AML1/ETO) where appropriate. RESULTS: The median age was 20 years (interquartile range, 15-32) at ovarian tissue cryopreservation. Before undergoing hematopoietic stem cell transplantation, all patients received induction or consolidation chemotherapy that included cytarabine + daunorubicin or Berlin-Frankfurt-Munich-95 protocol and were in remission. The mean serum antimüllerian hormone was 1.9±1.7 ng/mL before ovarian tissue cryopreservation. In all cases, ovarian tissue screening for leukemic cells was negative. Ovarian transplantation was performed laparoscopically with or without robotic assistance, after a median of 74.5 months (interquartile range, 41-120) after ovarian tissue cryopreservation. Ovarian function resumed in all patients after a median of 3.0 months (range, 2.5-4.0), and 2 women had 1 live birth each. The median graft longevity was 35.5 months (interquartile range, 18-57) after ovarian tissue transplantation. After a median follow-up of 51 months (interquartile range, 20-74), all patients remained relapse-free. In 1 patient, the graft was removed during cesarean delivery and was negative for immunochemical leukemia markers. CONCLUSION: Our long-term follow-up demonstrated no evidence of disease relapse after ovarian tissue transplantation in patients with acute leukemia who received allogeneic hematopoietic stem cell transplantation. This safety profile may be explained by the fact that these patients are induced into remission by nongonadotoxic induction chemotherapy before undergoing ovarian tissue cryopreservation. We propose that ovarian tissue cryopreservation should not be excluded as a fertility preservation option for young women with leukemia who are due to receive preconditioning chemotherapy before allogeneic hematopoietic stem cell transplantation.

STUDY OBJECTIVE: To define objective and readily applied diagnostic criteria for Y-shaped uteri using 3-dimensional transvaginal ultrasound (3D-TVUS) volume recordings. DESIGN: A retrospective case-control diagnostic measurements study. SETTING: A tertiary university hospital's reproductive health and research center. PATIENTS: Two hundred thirteen patients who presented with infertility between January 2020 and December 2022. INTERVENTIONS: Two blinded physicians re-evaluated the 3D-TVUS images of all patients for the presence of a uterine abnormality. The images of patients with a Y-shaped uterus were re-evaluated, and descriptive measurements were done. MEASUREMENTS AND MAIN RESULTS: The most common uterine abnormality in this cohort was the Y-shaped uterus with a prevalence of 12.2%, followed by the arcuate, T-shaped, and septate uteri, respectively. Reviewers identified 26 and 28 Y-shaped uteri, respectively, and came to a consensus on 25 images. Diagnostic criteria for the Y-shaped uterus based on 3D-TVUS findings have been specified as: lateral indentation depths between 4 and 7 mm, fundal indentation depth between 5 and 9 mm, lateral indentation angles between 121° and 149°, fundal indentation angle between 121° and 145°, and Y-angles 25° to 46°. CONCLUSION: Some subtypes of dysmorphic uteri, such as the Y-shaped uterus, whose clinical significance is unknown and may be variants of the normal, may actually be more common than thought. Determining objective diagnostic criteria with 3D-TVUS will allow standard research on these anomalies and their clinical significance.

Background and Objectives: The objective of this study was to evaluate the impact of adjuvant letrozole administration during ovarian stimulation using the gonadotropin-releasing hormone (GnRH) antagonist protocol on treatment outcomes in women categorized into POSEIDON groups 3 and 4. Materials and Methods: This retrospective cohort study analyzed data from patients classified into POSEIDON groups 3 and 4 who underwent fresh embryo transfer subsequent to intracytoplasmic sperm injection following a GnRH antagonist stimulation protocol between January 2017 and December 2021. Patients were divided into two groups: the GnRH-LZ group, who received letrozole at a dosage of 5 mg/day for five consecutive days, and the GnRH-ant group, who did not receive adjuvant letrozole. The primary outcome measure of the study was a comparative analysis of live birth rates between the two groups. Results: A total of 449 patients were deemed suitable for final analysis and were allocated into two groups: 281 patients in the GnRH-ant group and 168 patients in the GnRH-LZ group. Live birth rates were found to be comparable in both groups (11% vs. 9%, p = 0.497). Letrozole administration significantly reduced the total amount of gonadotropins required (2606.2 ± 1284.5 vs. 3097.8 ± 1073.3, p < 0.001), the duration of ovarian stimulation (11.2 ± 3.9 vs. 10.2 ± 3, p = 0.005), and the serum peak estradiol concentration (901.4 ± 599.6 vs. 463.8 ± 312.3, p < 0.001). Conclusions: Adjuvant letrozole administration did not demonstrate a significant impact on live birth rates among women categorized into POSEIDON groups 3 and 4. However, this approach may offer potential cost reductions by diminishing the necessity for exogenous gonadotropins and shortening the duration of ovarian stimulation.

The aim of this systematic review and meta-analysis was to quantify the effect of random start ovarian stimulation (RSOS) compared with conventional start ovarian stimulation (CSOS) in cancer patients before gonadotoxic treatment. The final analytical cohort encompassed 688 RSOS and 1076 CSOS cycles of cancer patients before gonadotoxic treatment. Eleven studies were identified by database searches of MEDLINE, Cochrane Library and cited references. The primary outcomes of interest were the number of oocytes and mature oocytes collected, the number of embryos cryopreserved and the metaphase II (MII)-antral follicle count (AFC) ratio. The studies were rated from medium to high quality (from 6 to 9) according to the Newcastle-Ottawa Quality Assessment Scale. The two protocols resulted in similar numbers of oocytes collected, MII oocytes, embryos available for cryopreservation and comparable MII-AFC and fertilization rates. The duration of ovarian stimulation was longer (standardized mean difference [SMD] 0.35, 95% CI 0.09 to 0.61; Pâ¯=â¯0.009) and gonadotrophin consumption was higher (SMD 0.23, 95% CI 0.06 to 0.40; Pâ¯=â¯0.009) in RSOS compared with CSOS. This systematic review and meta-analysis show that the duration of stimulation is longer, and the total gonadotrophin consumption is higher in cancer patients undergoing RSOS compared with those undergoing CSOS, with no significant effect on mature oocyte yield.

PURPOSE: We aimed to compare the feasibility, effectiveness, and safety of transabdominal ultrasound-guided oocyte retrieval (TUGOR) using a vaginal probe and traditional vaginal approach in virgin patients undergoing oocyte cryopreservation. METHODS: A total of 116 virgin patients who underwent transabdominal ultrasound-guided oocyte retrieval using a vaginal ultrasound probe and 33 patients matched for BMI, antral follicle count, age, day 3 FSH, estradiol, and AMH who underwent vaginal approach were enrolled. Mean number of total oocytes collected, mean number of cryopreserved MII oocytes, duration of the procedure, duration of stimulation, mean gonadotropin consumption, mature oocyte ratio, and a modified follicle-oocyte index were compared between the groups. RESULTS: No statistical difference was found between the groups in mean number of follicles > 12 mm (4.62 ± 4.54 vs. 5.44 ± 4.52), mean number of oocytes collected (4.44 ± 4.14 vs. 5.33 ± 4.52), mean number of cryopreserved MII oocytes (4.01 ± 3.67 vs. 4.53 ± 4.13), mean duration of the procedure (12.4 ± 1.2 vs. 13.4 ± 1.6 min), mean days of stimulation (8.05 ± 1.91 vs. 8.35 ± 1.72 days), mean gonadotropin consumption (1507.9 ± 475.3 vs. 1571.74 ± 404.6 units), mature oocyte ratio (0.78 ± 0.24 vs. 0.82 ± 0.26), and modified follicle oocyte index (0.86 ± 0.63 vs. 0.84 ± 0.19). In the TUGOR group, superficial epigastric artery injury occurred in two patients and resolved spontaneously. CONCLUSION: Transabdominal oocyte retrieval using a vaginal ultrasound is a safe, effective, and feasible method of oocyte retrieval in some selected patient groups.

High levels of serum inflammatory markers are related to extended hospitalisation and more severe disease in the case of tubo-ovarian abscess (TOA). There is scarce information on the serial measurement of inflammatory markers during the postoperative follow-up period of surgically treated TOA. The present study aimed to assess the postoperative longitudinal changes in serum inflammatory markers following surgery for TOA. In this retrospective cohort study, patients who underwent surgery for TOA between January 2010 and March 2020 were reviewed. All inflammatory markers peaked within 48 hours after surgical intervention and then declined with time. The predicted mean of white blood cell count (WBC) to return to normal was 2.5 days (95% CI: 1.0-4.3), which was followed by neutrophil to lymphocyte ratio (NLR) (7.1 days, 95% CI: 4.7-10.8) and C-reactive protein (CRP) (+14 days). In conclusion, serum inflammatory markers increase in the very early post-operative period. While the normalisation period is very slow, it may not be appropriate to use CRP for evaluating the treatment success of TOA surgery. However, WBC and NLR measurements might be useful for follow-up and predicting the need for medical or surgical intervention.Impact statementWhat is already known on this subject? Serum inflammatory markers such as C-reactive protein, white blood cell count, and neutrophil to lymphocyte ratio are usually elevated in women with tubo-ovairan abscess, and high levels of these markers are associated with extended hospitalisation and more severe disease.What do the results of this study add? Our results indicate that the serum inflammatory markers increase and peak within the first 48 hours after surgery for tubo-ovarian abscess. Normalisation of white blood cell count is the fastest in successfully treated patients. However, normalisation of C-reactive protein is slowest, reaching 14 days and might not be as feasible as white blood cell count and neutrophil to lymphocyte ratio in postoperative patient follow-up.What are the implications of these findings for clinical practice and further research? The serum inflammatory markers should be interpreted with caution within 48 hours after surgical treatment for tubo-ovarian abscess. Instead of C-reactive protein white blood cell count, and neutrophil to lymphocyte ratio measurements can be preferred in post-operative follow-up to predict the need for further medical or surgical intervention.

The present retrospective cohort study analysed data of couples with unexplained infertility who underwent two to three intrauterine insemination (IUI) cycles. The inclusion criteria were age 20-40 years, failure to conceive for at least two years of unprotected intercourse, ovulation, normal semen analysis, and tubal patency. Total of 578 IUI cycles of 286 couples with unexplained infertility were included in the final analyses. The mean age and duration of infertility of the study population were 28.8 ± 5.1 and 5.2 ± 3.4 years, respectively. The clinical pregnancy rate (CPR) and live birth rate (LBR) per cycle were 16.6 and 13.1%, respectively. The cumulative CPR following two to three IUI cycles was 33.5% and the cumulative LBR was 26.5% for the entire cohort. The duration of infertility was significantly shorter in women whose IUI attempt were successful (p = .036). Up to three cycles of IUI with ovarian stimulation seems as an effective first-line treatment modality in unexplained infertility.IMPACT STATEMENTWhat is already known on this subject? Cont rolled ovarian stimulation combined with intrauterine insemination (IUI) is a common infertility treatment as a low-cost, less-invasive alternative to in vitro fertilisation (IVF) and was approved as a first line treatment option for unexplained infertility However, the UK National Institute for Health and Care Excellence (NICE) guideline states that IUI is not recommended to couples with unexplained infertility, male factor and mild endometriosis, unless the couples have religious, cultural or social objections to proceed with IVF.What do the results of this study add? Up to three IUI cycles with ovarian stimulation can be considered as an effective treatment modality in unexplained infertility even in couples who could not achieve pregnancy by expectant management for two years.What are the implications of these findings for clinical practice and/or further research? The clinicians should reconsider the NICE recommendation of IVF in the light of recent studies including ours which recommend IUI together when dealing couples with unexplained infertility.

PURPOSE: To define whether transabdominal ultrasound guided oocyte retrieval (TUGOR) is a feasible, effective and safe method. METHODS: A total of 64 patients who underwent TUGOR in a tertiary referral university hospital in vitro fertilization (IVF) clinic were enrolled. Indications, total number of oocytes collected, total number and percentage of mature oocytes, duration of procedure, complication rates and total number of fertilized oocytes were assessed. RESULTS: The indications for TUGOR were as follows; virgin women with decreased ovarian reserve who opted fertility preservation (n = 52, 81.1%), Ewing Sarcoma (n = 1, 1.56%), breast cancer (n = 4, 6.2%), lymphoma (n = 1, 1.56%) endometrioma (n = 1, 1.56%), immature teratoma of the ovary (n = 1, 1.56%), multiple large uterine fibroids (n = 2, 3.1%), adnexal transposition due to bowel surgery (n = 1, 1.56%) and Mayer Rokitansky Küster Hauser Syndrome (n = 1, 1.56%). Total number of oocytes retrieved and mean number of oocytes collected were 315 and 4.92 ± 1.7 (range 1-21), respectively. The mean duration of the procedure was 12.4 ± 1.2 min. The number and percentage of mature oocytes were 272 and 86.3%, respectively. A total of 14 embryos were frozen in four patients and one blastocyst transfer was performed ending up with live birth. Superficial epigastric artery injury occurred in two patients and resolved spontaneously. No oocyte was retrieved in five patients with single growing follicle in the first attempt. CONCLUSION: TUGOR is a feasible, effective and safe method of oocyte retrieval for the purpose of fertility preservation or in patients with inaccessible ovaries via transvaginal route undergoing IVF.

PURPOSE: To assess the association between operative hysteroscopy prior to assisted reproductive technology (ART) cycle and cervical insufficiency (CI) in the second trimester of pregnancy. METHODS: A retrospective cohort study was conducted. The charts of all women who got pregnant following an ART cycle between January 2015 and June 2018 were reviewed. The study group consisted of pregnant women who underwent operative hysteroscopy within 6 months before conception. The control group consisted of pregnant women who did not undergo hysteroscopy or any type of cervical surgical procedure before conception. The primary outcome measure was CI during the second trimester (13-27 weeks of gestation). RESULTS: A total of 363 pregnancies achieved by ART cycles were assessed. After the exclusion of multiple pregnancies (n = 19), previous surgical procedures (n = 4) and first-trimester pregnancy losses (n = 80), there were 29 women in the study group and 231 women in the control group. The mean ages of the study and control groups were 31.2 ± 4.06 and 29.82 ± 4.71 years, respectively (P = 0.13). The indications for operative hysteroscopy were uterine septum (n = 19), T-shaped uterus (n = 4), endometrial polyp (n = 4), and submucosal fibroids (n = 2). The rates of CI in the study and control groups were 13.7% (4/29) and 3.4% (8/231), respectively (P = 0.012). The term delivery rates in the study and control groups were 79.3 and 91.8%, respectively (P = 0.044). CONCLUSIONS: Operative hysteroscopy prior to ART cycles is significantly associated with CI between 13 and 27 weeks of gestation. Further investigation with larger cohorts is urgently needed to clarify this issue.

The aim of this study was to assess the effect of laparoscopic removal of endometrioma on assisted reproductive technology (ART) outcome. A retrospective cohort study was conducted at a university hospital between January 2014 and December 2017. The ART group consisted of 26 women who underwent 44 ART cycles in the presence of ovarian endometrioma and the surgery group consisted of 53 women who underwent 58 ART cycles after laparoscopic removal of ovarian endometrioma/s. There were no statistically significant differences between the groups regarding demographic parameters and background features including cycle parameters. The live birth rates in the ART and Surgery groups per embryo transfer were 23.7 and 26.1%, respectively (p = .800). The rate of cycle cancellation due to poor response and/or failed oocyte retrieval was significantly higher in the Surgery group than ART group (13.7 vs. 0%, respectively; p = .018). In conclusion, cystectomy significantly increases the risk of cycle cancellation due to poor ovarian response, which might be catastrophic individually. However, it does not seem to affect the live birth rates.IMPACT STATEMENTWhat is already known on this subject? Both the presence of an endometrioma or surgical removal may have deleterious effects on fertility potential.What do the results of this study add? Our results confirm that although cystectomy has no benefit on the number of oocytes collected and live birth rate, it increases the risk of cycle cancellation significantly in assisted reproductive technology cycles following endometrioma surgery.What are the implications of these findings for clinical practice and/or further research? Postponing cystectomy until a freeze-all cycle may be the best option to maximise the number of oocytes retrieved and to maximise the ovarian response.

PURPOSE: To report the first live birth after frozen-thawed ovarian transplantation in Turkey and the second case for an acute lymphoblastic leukemia (ALL) survivor in the world. METHODS: A 19-year-old patient underwent ovarian tissue cryopreservation (OTC) before cord blood transplantation in 2010. She was diagnosed as ALL with a bone marrow biopsy revealing 90% blast ALL-L2 type, and karyotype analyses indicated reciprocal translocation at t(9;22)(q34;q11). The patient received the Berlin-Frankfurt-Munster (BFM) protocol, and complete remission was achieved before fertility preservation. Serum AMH level was measured as 1.5 ng/ml, and 12 antral follicles were counted on ultrasound. She was informed about fertility preservation options and decided to proceed with OTC, with her signed consent before cord blood transplantation in April 2011. Ovarian tissue transplantation (OTT) was performed in 2017 when the patient was menopausal with serum FSH levels > 100 IU/ml and estradiol < 20 pg/ml and hematologically in molecular remission. Detailed molecular analysis, standard histology, and immunohistochemistry demonstrated that the thawed tissue is free of malignant cells. RESULTS: Six months following OTT, she had spontaneous menstruation with serum FSH 11 IU/ml and estradiol 53 pg/ml. Two consecutive IVF cycles yielded three top-quality embryos. Following three embryo transfer cycles, one fresh and two frozen, a healthy term live birth was achieved. Frozen-thawed-transplanted tissues were extracted during caesarean delivery upon the patient's request after a total period of 25 months in vivo, and histopathological evaluation revealed that the tissue was free of leukemic infiltration. CONCLUSION: The authors report the first pregnancy and live birth in Turkey and the second live birth in the world following transplantation of frozen-thawed ovarian tissue in a leukemia survivor. As the transplanted tissues were removed during caesarean delivery, histological findings prove the functionality and the malignant-free status of the transplanted tissue during the grafted period.

While luteinizing hormone (LH) activity is believed to play a role in follicle maturation, human chorionic gonadotropin (hCG) might play an important role in implantation process. We aimed to investigate whether addition of human menopausal gonadotropin (hMG) in recombinant-follicle-stimulating hormone (r-FSH) started GnRH antagonist controlled ovarian hyperstimulation (COH) cycles might enhance implantation rate and improve in vitro fertilization (IVF) success. A total of 246 patients undergoing GnRH antagonist IVF cycles were analyzed. One hundred and twenty-three cycles (%50) were treated with only r-FSH and 123 cycles were treated with r-FSH plus hp-hMG combination. Total gonadotropin doses, total number of oocytes retrieved, metaphase 2 (MII) oocytes, top quality embryos, fertilization and implantation rates, clinical pregnancy rates (CPRs) and ovarian hyperstimulation syndrome (OHSS) rates were compared between the groups. Both groups were comparable in terms of demographic details and baseline characteristics. Peak estradiol and progesterone levels in hCG trigger day, number of retrieved oocytes and top quality embryo counts, fertilization rates were similar between the groups. In r-FSH + hp-hMG group, significantly higher implantation rates (35.3% vs 24.3%, p=.017), CPRs (51.2% vs 35.8%, p=.015) and lower OHSS rates (1.6% vs 7.4%, p = .03) were observed respectively compared to r-FSH only treated patients. In conclusion, addition of hp-hMG on the day of antagonist initiation might increase CPRs. A better endometrial receptivity associated with higher implantation rates might be achieved due to hCG component in hp-hMG.

Here, we present a diffuse large B cell lymphoma patient admitted for fertility preservation before cancer therapy and whose pregnancy was recognized incidentally just after the start of random start controlled ovarian stimulation (RSCOH) during the stimulation cycle. Despite an optimal homogenous growth of follicle cohort, majority of the retrieved oocytes were immature after GnRHa trigger. Possible effects of extremely high serum progesterone and/or ß-hCG levels on oocyte in vivo maturation are discussed with the surprising high rate of in vitro maturation and subsequent good embryo development. It seems that in case of need for pregnancy termination as a result of an urgent cancer therapy, RSCOH can be started and patients may benefit from overnight in vitro maturation of oocytes.

Background/aim: To investigate the relationship between subfertility etiologies and success rates in controlled ovarian stimulation and intrauterine insemination (COSIUI) cycles. Materials and methods: The medical records of 218 couples who applied to a university-based fertility center were analyzed retrospectively. Detailed infertility examination data and pregnancy outcomes were compared according to different subfertility etiologies. The study groups with regard to subfertility etiologies were minimalmild endometriosis, unexplained infertility, and mild male infertility. The primary outcome measure was live birth rate. Results: There were no statistically significant differences between the groups regarding demographics except for total motile sperm count. Live birth rates in the male infertility group were comparable to the endometriosis and unexpected infertility groups (6.6%, 11.9%, and 10.3%, respectively; P = 0.63). Conclusion: The success rate of the mild male subfertility group following COSIUI cycles for live birth rates was similar to those of the endometriosis and unexplained subfertility groups.

Triptorelin 0.2 mg and leuprolide 1 mg subcutaneous injections for triggering final follicular maturation were compared in patients with a high risk for ovarian hyperstimulation syndrome (OHSS). Infertile patients treated with GnRH antagonist protocol between January 2014 and March 2016 were recruited. Patients with high serum oestradiol levels on HCG day (>3000 pg/ml) indicating a risk of OHSS consisted of the study groups (A and B). Patients with serum oestradiol levels less than 3000 pg/ml consisted of the control group (C). A single injection of 0.2 mg triptorelin, 1 mg leuprolide and 10000 IU HCG were administered for final oocyte triggering in groups A (n = 63), B (n = 74) and C (n = 131), respectively. Demographic parameters were comparable between the groups. No cases of severe or moderate OHSS occurred in any group. The clinical pregnancy rates were 31.7%, 37.8% and 32.8% in groups A, B and C, respectively. Both injections had comparable efficacy in clinical outcome and OHSS risk. Regardless of preferred drug, GnRH agonist trigger for final oocyte maturation seems to be safe for patients with high OHSS risk, and can be safely used in fresh embryo transfer cycles.

OBJECTIVE: To investigate the effect of additional endometrial scratching procedure during hysteroscopy on assisted reproductive technology (ART) cycle outcomes in repeated implantation failure (RIF) patients without endometrial or uterine abnormalities on hysteroscopic evaluation. MATERIALS AND METHODS: Three hundred and forty-five RIF patients who underwent ART at a university-based infertility clinic between January 2011 and June 2015 were recruited in this retrospective cohort study. Uterine cavities of all included patients were evaluated by diagnostic hysteroscopy 7-14 days prior to the subsequent ART cycle. Women without endometrial abnormalities were allocated into two groups; the scratching group was consisted of patients who underwent endometrial scratching by using monopolar electric energy with needle forceps during hysteroscopy, and the control group was consisted of patients who underwent only diagnostic hysteroscopy. RESULTS: The implantation rate was significantly higher in the scratching group than the control group (37.7% versus 24.5%; p = 0.04). Clinical and ongoing pregnancy rates were also found to be significantly higher in the scratching group than the control group (37.7% versus 27.6%; p = 0.03; and 33.3% versus 23%; p = 0.03, respectively). CONCLUSION: Endometrial scratching during diagnostic hysteroscopy seems to enhance implantation and as well pregnancy rates in comparison to diagnostic hysteroscopy alone.

The aim of the present study was to compare follicular fluid (FF) levels of norepinephrine (NE) and dopamine (DA) in polycystic ovary syndrome (PCOS) and non-PCOS patients who underwent in vitro fertilization (IVF). Forty-seven PCOS patients (study group) and 61 patients with male factor infertility (control group) who underwent IVF using GnRH agonist protocol were recruited. Concentrations of NE and DA were measured in FF specimens of all patients. Demographic characteristics were comparable between the groups. Significantly higher levels of NE were measured in FF of PCOS patients (median: 61.05 nmol/l) compared to those with male infertility (median: 49.82 nmol/l). Similarly, significantly higher levels of DA were measured in FF of PCOS patients (median: 23.70 nmol/l) compared to those with male infertility (median: 18.28 nmol/l). In conclusion, the FF concentrations of both catecholamine are increased in PCOS patients when compared to non-PCOS patients.

AIM: The aim of this study was to evaluate whether dual trigger with leuprolide acetate plus recombinant human chorionic gonadotropin (hCG) improves in vitro fertilization outcome in gonadotropin-releasing hormone antagonist cycles. METHODS: A total of 156 patients diagnosed with mild male factor, unexplained or tubal factor infertility were enrolled in the study. All subjects were allocated into one of two groups: the dual trigger group (leuprolide acetate 500 µg + recombinant hCG 250 µg) and the standard group (recombinant hCG 250 µg) according to the selected trigger method. Oocyte trigger was performed when at least three follicles >17 mm were observed. Pregnancy rate, number of collected oocytes, number of metaphase II oocytes, number of grade-A embryos, cycle cancellation rate, and ovarian hyperstimulation syndrome rate were the main outcome measures for the study. RESULTS: The mean number of grade-A embryos (1.6 ± 1.5 vs 1.1 ± 1.4, P = 0.01) and of metaphase II oocytes (7.9 ± 4.6 vs 6.3 ± 5.8, P = 0.02) was significantly higher in the dual-trigger group. Pregnancy rate was significantly higher in the dual-trigger group than in the standard group (54.8 vs 37.5%, P = 0.006). Two cases of mild ovarian hyperstimulation syndrome were observed in each group. CONCLUSION: This novel and more physiological trigger approach using 500 µg leuprolide acetate plus 250 µg recombinant hCG may lead to an increase in the number of metaphase II oocytes, grade-A embryos, and may improve pregnancy rates.

AIM: The aim of this study was to assess the diagnostic accuracy of hysterosalpingography (HSG) on tubal patency (TP) and to determine whether performing laparoscopy (LS) can change the original management strategy based on HSG findings. MATERIAL AND METHODS: Records of all infertile couples (n = 1298) treated at a university-based infertility clinic between January 2002 and June 2010 were reviewed. All patients who had both HSG and LS testing (n = 264) were included in the study. HSG was performed in an attempt to rule out tubal and/or uterine pathologies. All patients included in the study were evaluated with LS not more than 12 months after HSG. RESULTS: The validity of HSG screening for TP was calculated as 84.1%. The positive and negative predictive values of HSG were 54.6% and 98.3%, respectively. The sensitivity of HSG was higher in patients with distal tubal occlusion than in patients with proximal tubal occlusion (69.8% [44/63] vs 46.7% [28/60], respectively; P = 0.011). The rates of management plan change in patients with bilateral TP, unilateral tubal occlusion and bilateral tubal occlusion were 2.8%, 12.2% and 32.4%, respectively (P = 0.000). CONCLUSIONS: Patients with both unilateral tubal occlusion and bilateral tubal occlusion on HSG should be reevaluated with LS to determine the appropriate management strategy.
