Association of serum and follicular fluid leptin and ghrelin levels with in vitro fertilization success.

Objectives: The aim of this study was to evaluate the relationship between in vitro fertilization (IVF) cycle outcomes, serum and follicular fluid (FF) levels of leptin and ghrelin. Material and methods: Forty-four women who underwent intracytoplasmic sperm injection cycles (ICSI) were enrolled in the study. On the third day (D3) of the menstrual cycle, venous blood samples were drawn for serum measurements of leptin and ghrelin. The follicular fluid (FF) and the corresponding oocyte were obtained from a single dominant preovulatory follicle at the time of oocyte pick-up. The FF and D3 serum leptin and ghrelin concentrations were measured by enzyme-linked immunosorbent assay. The relationship between pregnancy rate and serum, follicular fluid levels of leptin and ghrelin were analyzed. Results: Of the 44 cases included, nineteen achieved clinical pregnancy (43.18%). Follicular fluid ghrelin levels were significantly lower in the pregnant group than non-pregnant group (p < 0.05) With respect to FF leptin, there was no statistically significant differences between the pregnant and non-pregnant women (p > 0.05). There was no statistically significant difference in D3 serum ghrelin between pregnant and non-pregnant groups (p > 0.05). However, D3 serum leptin levels were significantly lower in pregnant women than non-pregnant women (p < 0.05). Conclusions: Lower ghrelin levels in the follicular fluid were associated with higher pregnancy rates. Also, D3 serum leptin levels were inversely correlated with clinical pregnancy rates. These findings support the potential role of these molecules on IVF outcomes.

Does obesity have detrimental effects on IVF treatment outcomes?

BACKGROUND: The aim of this study was to investigate the influence of body mass index (BMI) on the in vitro fertilization (IVF) treatment outcomes in a cohort of women undergoing their first IVF, using an intracytoplasmic sperm injection (ICSI). METHODS: This retrospective cohort study included 298 cycles from women younger than 38 years old undergoing IVF-ICSI at a university infertility clinic. The treatment cycles were divided into three groups according to the BMI of the women involved: normal weight (18.5 ≤ BMI < 25 kg/m(2), 164 cycles), overweight (25 ≤ BMI < 30 kg/m(2), 70 cycles), and obese (BMI ≥ 30 kg/m(2), 64 cycles). The underweight women (BMI < 18.5 kg/m(2)) were not included in the analysis due to small sample size (n = 22). The patient characteristics and IVF-ICSI treatment outcomes were compared between the BMI groups. RESULTS: The total gonadotropin dose (p <0.001) and duration of stimulation (p = 0.008) were significantly higher in the obese group when compared to the normal BMI group. There were no significant differences across the BMI categories for the other IVF-ICSI cycle outcomes measured, including the number of retrieved oocytes, mature oocytes, embryos suitable for transfer, proportion of oocytes fertilized, and cycle cancellation rates (p >0.05 for each). Additionally, clinical pregnancy, spontaneous abortion, and the ongoing pregnancy rates per transfer were found to be comparable between the normal weight, overweight, and obese women (p >0.05 for each). CONCLUSION: Obese women might require a significantly higher dose of gonadotropins and longer stimulation durations, without greatly affecting the pregnancy outcomes.

Chitotriosidase levels in patients with severe endometriosis.

OBJECTIVE: To study the levels of chitotriosidase activity in the peritoneal fluid and the plasma of patients with severe endometriosis and control subjects. MATERIALS AND METHODS: Twenty-five women with laparoscopically and histopathologically confirmed endometriosis (study group) and 27 control patients who had undergone laparoscopic surgery were included. Peritoneal fluid and peripheral blood were obtained from all the patients before the surgery. Chitotriosidase activities were measured. RESULTS: Analysis of chitotriosidase activity in the peritoneal fluid of patients with endometriosis showed that there was no significant difference between endometriosis and control group, respectively (32.04 ± 64.20 vs. 15.25 ± 31.17 nmol/mL/h; p > 0.05). Analysis of chitotriosidase activity in plasma of patients with endometriosis showed significantly increased levels of chitotriosidase levels compared with the control group (74.81 ± 60.54 vs. 14.10 ± 26.17; p < 0.001), respectively. CONCLUSION: We found that the activity of chitotriosidase in plasma was statistically higher in severe endometriosis patients than women without endometriosis.

The timing of micro-TESE: what is the ideal age for male and female partner to bring a child to home?

OBJECTIVE: The aim of this study was to analyze the results of microsurgical testicular sperm extraction (micro-TESE) and investigate the potential factors that may affect the successful sperm retrieval and timing of micro-TESE. METHODS: A total of 56 patients with nonobstructive azoospermia (NOA) who underwent micro-TESE procedure between January 2017 and December 2019 were retrospectively analyzed. The patient age, marriage duration, infertility duration, smoking, chronic illness, varicocele status, previous scrotal surgeries, and the presence of genetic disease were noted by an urologist for all patients. RESULTS: The mean age of patients was 33.28±4.4 (22-44) years. Our total sperm-retrieval rate was 55.4% (n:31). Sixteen (28.6%) pregnancies were achieved and 15 (26.8%) healthy live births could be managed. Only the marriage duration (p=0.016) and infertility duration (p=0.015) were detected to be the significant factors to manage successful sperm retrieval. Men with NOA younger than 35.2 years and having a female partner younger than 36.9 years seemed to have the best chance to have a living healthy baby. CONCLUSIONS: The fertility decreased by both male and female age and for men with NOA. The early visit to doctor seemed to have positive effect.

Prevalence and predictors of the usage of complementary alternative medicine among infertile patients.

PURPOSE: The primary objective of this study was to evaluate the prevalence, characteristics and the most frequently used complementary and alternative medicine (CAM) methods among infertile couples. A secondary aim was to assess predictors and patients' attitude to disclose the usage of CAM. METHODS: This study was designed as a cross-sectional survey and conducted on patients admitted to infertility clinics of two hospitals. RESULTS: The overall prevalence of CAM among 324 infertile participants (162 couples) was 25.6 % (n = 83). 48 % of the infertile couples had experience with at least one type of CAM method and the most commonly used CAM was herbal products (84 %). The frequency of CAM tended to be higher among females compared to males (33 % versus 17 %, respectively; p = 0.02). Patients who failed to conceive with previous medical therapies were more inclined to use CAM (p = 0.01). After logistic regression analyses, only gender and previous unsuccessful ART treatment were found to be associated independently with CAM use. CONCLUSION: CAM use is common among infertile population. CAM users were more likely to be women at any age who had failed to achieve a pregnancy with previous artificial reproductive treatment(s), mainly used herbal products and mostly reluctant to report the use of CAM.

The outcome of adding peripheral neuromodulation (Stoller afferent neuro-stimulation) to anti-muscarinic therapy in women with severe overactive bladder.

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.

Continuous vaginal and bilateral thoracic fluid drainage for management of severe ovarian hyperstimulation syndrome.

Severe ovarian hyperstimulation syndrome (OHSS) is a serious and potentially fatal complication of ovarian stimulation. A 29-year-old nulligravid patient with anovulatory infertility was treated with in vitro fertilization. Six days after embryo transfer, the patient presented with complaint of abdominal bloating, nausea, vomiting and shortness of breath. Severe late-onset OHSS, with massive ascites and pleural effusion, was diagnosed. Posterior colpotomy was performed under general anesthesia, a Foley catheter was inserted into the posterior cul-de-sac, and bilateral chest drainage tubes were left for continuous drainage. In total, 13.2 liters of ascites and 6.1 liters of pleural fluid were drained in 8 days. Continuous drainage of ascites and pleural effusion improved the patient's comfort without need for repeated transvaginal and thoracic aspirations.

Assessment of the predictive value of serum progesterone levels on early pregnancy prognosis in spontaneous twin gestations: a prospective study.

OBJECTIVES: The aim of this study was to assess the predictive value of serum progesterone levels in early pregnancy prognosis in spontaneous dichorionic-diamniotic twin gestations. STUDY DESIGN: This study was carried out among 38 spontaneous dichorionic-diamniotic twin gestations between January 2003 and June 2005 in the Department of Obstetrics and Gynaecology at the Gulhane Military Medical Academy. Serum progesterone levels were measured at 7 and 10 weeks' gestation and pregnancies were followed until 14 gestational weeks by ultrasound examination. RESULTS: We found that a progesterone level of 58 nmol/l in the 7th gestational week and of 51 ng/ml at 10 gestational weeks has a predictive value for viable intrauterine twin pregnancies with 83% sensitivity and 69% specificity and 83% sensitivity and 84% specificity, respectively. CONCLUSION: Progesterone levels in the early gestational weeks may be a biochemical marker for the prediction of a twin pregnancy outcome and may reduce the number of ultrasound examinations.

What should be the protocol selection after failure of in-vitro fertilization at normoresponder patients: Agonist or antagonist?

OBJECTIVE: Evaluation of the impact of agonist or antagonist protocol selection on pregnancy outcomes after failure of in-vitro fertilization (IVF) treatment cycles which were down regulated with Gonadotropin Releasing Hormone (GnRH) agonist. MATERIALS AND METHODS: This was a retrospective study. Two hundred and sixty nine patients who were treated with GnRH agonist protocol between years 2002-2012 at an IVF unit and underwent a second attempt following one year period after failure of IVF enrolled in the study. Age, basal FSH levels, antral follicle counts, duration of induction, the number of yielded oocytes, the number of transferred embryos and the transfer days, clinical and ongoing pregnancy rates were evaluated for each treatment cycle. RESULTS: Normoresponder patients were separated into two groups according to the agonist or antagonist protocol selection at the second attempt and the results of two consequent IVF cycles were compared. There were no statistically significant difference between the groups for the dosage of administered gonadotropin, duration of induction, the count of yielded oocytes, the day and the number of transferred embryos (p>0.05). Furthermore the fertilization rate, clinical and ongoing pregnancy rates were similar in two groups. CONCLUSION: The selection of antagonist treatment is effective as agonist protocols at normoresponder patients after failure of IVF.

Comparison of aromatase inhibitor (letrozole) and immunomodulators (infliximab and etanercept) on the regression of endometriotic implants in a rat model.

OBJECTIVE: Novel treatment strategies are needed in the treatment of endometriosis due to limited success rates with the currently available options. As inflammatory and immunological mechanisms have been shown to be involved in the mechanism of the disease, new modalities are likely to emerge. We investigated the effects of infliximab (INF), etanercept (ETA) and letrozole on the regression of experimental endometriosis. STUDY DESIGN: In this experimental randomized trial, endometriosis was induced surgically in 44 adult female Sprague-Dawley rats. Establishment of implants was confirmed in 41 animals by a second operation on the 21st day. The rats were then randomly divided into four groups. Group I (n = 10) served as controls. Group II (n = 11) received letrozole (0.18 mg/kg, i.p.), group III (n = 10, i.p.) ETA (2.016 mg/kg, i.p.), and group IV (n = 10) INF (15.12 mg/kg, i.p.) for a second 21-day period. Endometriotic implant size along with peritoneal fluid VEGF level and immunoreactivity were determined before and after the treatment in each group. RESULTS: Endometriotic implant size reduced in all treatment groups. The effect of letrozole and ETA on implant size was similar but was significantly better than INF. Level of VEGF in peritoneal fluid did not change in any treatment group but post-treatment VEGF immunoreactivity was found significantly lower in the letrozole treated group. CONCLUSIONS: Letrozole and ETA caused a regression on the implant size in experimental endometriosis. The only group with decreased VEGF expression was letrozole.

Expression of cyclooxygenase-2 and vascular endothelial growth factor in ovarian endometriotic cysts and their relationship with angiogenesis.

OBJECTIVE: To investigate the expression of cyclooxygenase-2 (Cox-2) and vascular endothelial growth factor (VEGF) in ovarian endometriotic cysts and assess their relation with angiogenesis. DESIGN: Experimental clinical study. SETTING: University hospital. PATIENT(S): Fifty patients with ovarian endometriotic cysts. INTERVENTION(S): Surgical excision of 50 ovarian endometriotic cysts. MAIN OUTCOME MEASURE(S): Microvessel density and the expression of Cox-2 and VEGF were analyzed immunohistochemically. RESULT(S): Cyclooxygenase-2 immunoreactivity was mainly cytoplasmic in glandular epithelial cells in all of the ovarian endometriotic cysts, with low expression in 12 cases (24%), moderate expression in 21 (42%), and high expression in 17 (34%). Vascular endothelial growth factor immunoreactivity was mainly cytoplasmic in stromal cells in 46 (92%) of the ovarian endometriotic cysts, with low expression in 12 cases (24%), moderate expression in 18 (36%), and high expression in 16 (32%). No immunoreactivity was present in 4 cases (8%). Both Cox-2 (r = 0.728) and VEGF (r = 0.670) were closely, statistically significantly related with microvessel density in ovarian endometriotic cysts. Cyclooxygenase-2 and VEGF also were highly statistically significantly correlated (r = 0.777) with each other. CONCLUSION(S): We observed Cox-2 expression mostly in glandular epithelial cells of ovarian endometriotic cysts, whereas VEGF expression was observed mainly in stromal cells. Cyclooxygenase-2 and VEGF were closely correlated with each other, and both of them appear to play a role in the angiogenesis of ovarian endometriosis.

Opinions of infertile Turkish women on gamete donation and gestational surrogacy.

OBJECTIVE: To determine the approval levels of infertile Turkish women concerning gamete donation and gestational surrogacy. DESIGN: Opinion survey. SETTING: Assisted reproductive treatment center at Gulhane Military Medical Academy. PATIENT(S): 368 women who had applied for infertility treatment. INTERVENTION(S): The patients were asked to answer a questionnaire that included questions about the patient's sociodemographic status, previous medical history with infertility treatment, and opinions on gamete donation and gestational surrogacy. MAIN OUTCOME MEASURE(S): Opinions of patients concerning gamete donation and gestational surrogacy. RESULT(S): Our data in this first study on infertile Turkish women show that some patients approve of gamete donation (23.3% for accepting oocytes and 3.4% for accepting sperm) and gestational surrogacy (15.1%). CONCLUSION(S): Donation and surrogacy are alternate treatments for the serious condition called infertility. As there are patients who would like to use these treatments, each of these patients should have the right to try any of them.

Successful treatment of cervical stenosis with hysteroscopic canalization before embryo transfer in patients undergoing IVF: a case series.

The course of the transfer catheter through the cervical canal is one of the most important issues for a successful embryo transfer (ET) during in vitro fertilization (IVF) cycles. Technically difficult ETs due to cervical stenosis are associated with reduced chance of pregnancy after assisted reproductive procedures. In the current case series, we report on three patients with cervical stenosis who underwent IVF-ET cycles. These three patients, in whom ET was classified as "difficult," failed to conceive with previous ET attempts. An intervention to create a cervical tract was performed with operative hysteroscopy under general anesthesia before transcervical ET. After the hysteroscopic shaving procedure, we observed quite an improvement in access to the endometrial cavity during ET procedure. These patients had significantly easier ET procedures compared with previous attempts and achieved clinical pregnancies. Hysteroscopic revision of the cervical canal results in easier ET and improves pregnancy rates in patients with cervical stenosis and histories of difficult ET.
