High serum progesterone levels on the day of embryo transfer in patients undergoing artificial frozen-thawed blastocyst transfer: Is there a ceiling effect?

Objective: To evaluate the potential ceiling effect of high serum progesterone levels on the day of embryo transfer for pregnancy outcomes in patients undergoing artificial frozen-thawed blastocyst transfer (FET) cycles. Materials and Methods: This retrospective cohort study included 595 patients who underwent artificial FET cycles. We evaluated progesterone levels and found that 40.6 ng/mL corresponded to the 90th percentile and 23.9 ng/mL corresponded to the 50th percentile. Based on these findings, we categorized progesterone levels as <20 ng/mL (n=220, 37.0%), 20-40 ng/mL (n=312, 52.4%), and ≥40 ng/mL (n=63, 10.6%). The primary outcome measures were the clinical pregnancy rate (CPR) and live birth rate (LBR). Results: Blastocyst morphology grades, including expansion, trophectoderm, and inner cell mass grades, were significantly associated with clinical pregnancy (p<0.001 for all). Progesterone levels between 20 and 40 ng/mL were associated with higher CPR (p=0.043). In the multivariate analysis, only blastocyst expansion and inner cell mass grades were independently and significantly associated with CPR [p=0.011, odds ratio (OR)=1.6, (confidence interval) CI 95%=1.13-2.39, and p=0.007, OR=1.65, CI 95%=1.14-2.39, respectively]. The progesterone level and trophectoderm grade were not statistically significant. Regarding LBR, only blastocyst expansion grades 4 and trophectoderm grades A or B were significantly associated. Conclusion: Based on these data, we speculate that if serum progesterone levels exceed 40 ng/mL on the day of embryo transfer in patients undergoing artificial FET cycles, there is no need to reduce the progesterone dose.

Individualized luteal phase support in frozen-thawed embryo transfer after intramuscular progesterone administration might rectify live birth rate.

Background: The serum P concentrations are suggested to have an impact on pregnancy outcome. However there is no consensus about the optimal progesterone cut-off during the luteal phase. Few studies evaluated the effectiveness of a "rescue protocol" for low serum P concentrations and most of these studies used vaginal progesterone administration. There is paucity of data on the effectiveness of rescue protocol using intramuscular progesterone (IM-P) in frozen-thawed embryo transfer (FET). Methods: This study is a retrospective cohort study included 637 single or double blastocyst FETs with artificially prepared endometrium receiving 100 mg IM progesterone (P) after incremental estrogen treatment. Serum P concentrations were evaluated using blood samples obtained 117-119 hours after the first IM-P administration and 21 ± 2 hours after the last IM-P administration. Patients with serum P concentrations <20.6 ng/ml on the ET day were administrated 400 mg vaginal progesterone for rescue. Results: Demographic and cycle characteristics were similar between patients receiving rescue vaginal P (embryo transfer (ET)-day P concentration < 20.6 ng/ml) and patients who did not need rescue vaginal P (ET-day P concentration ≥ 20.6 ng/ml). Clinical pregnancy, miscarriage, and live birth rates were similar between two groups: 52.9%(45/85) vs 59.6%(326/552), p=0.287; 11.1%(5/45) vs 14.1%(46/326), p=0.583; and 47.1%(40/85) vs 50.7%(280/552), p=0.526, respectively. Logistic regression analysis revealed that the female age (p = 0.008, OR=0.942, 95% CI = 0.902-0.984) and embryo quality (ref: good quality for moderate: p=0.02, OR=0.469, 95% CI =0.269-0.760; for poor: p=0.013, OR= 0.269, 95% CI = 0.092-0.757) were independent variables for live birth. Following rescue protocol implementation, ET-day P concentration was not a significant predictor of live birth. Conclusions: Rescue vaginal P administration for low ET day serum P concentrations following IM-P yields comparable live birth rates.

The effect of dienogest treatment on anti-Mullerian hormone in patients with endometrioma: a 12-month follow-up study.

Objective: To assess the effect of dienogest treatment on endometrioma (OMA) size, serum anti-Mullerian hormone (AMH) levels and associated pain over a 12-month follow-up period. Material and Methods: A longitudinal cohort study of 104 patients with OMA who were treated with dienogest, between January 2017 and January 2020. Of the included patients, each had a 12-month follow-up period with transvaginal or pelvic ultrasound and measurement of serum AMH concentration at the sixth and twelfth months of follow-up. The alteration in OMA size in the sixth and twelfth months of treatment was the primary outcome measure and the alteration in AMH concentration over the same period was the secondary outcome measure. The only exclusion criterion was having surgical intervention for OMA during the follow-up period (n=44). In patients with bilateral OMA (n=21), the change in size of the largest OMA was considered in the analysis. Results: A total of 60 patients with a mean ± standard deviation (SD) age of 31.5±8.0 years were included. The mean ± SD OMA size on the day the dienogest was started was 46.3±17.4 mm and the mean AMH level was 3.6±2.4 ng/mL. After six months, the mean OMA size had decreased to 38.6±14.0 mm, with a median difference of 7.8 mm [95% confidence interval (CI): 3.0 to 12.6; p=0.003]. The mean AMH level was 3.3±2.7 ng/mL at 6 months follow-up (95% CI: -0.2 to 0.8; p=0.23) and the average difference was 0.3 ng/mL. At the 12th-month visit, when compared with the beginning of the treatment, OMA size had again significantly decreased by a median of -8.9 mm (95% CI: -2.9 to -14.9; p=0.005), and the decline in median AMH was also significant (-0.9 ng/mL, 95% CI: -0.1 to -1.7; p=0.045). The initial mean ± SD visual analog scale pain score at the commencement of dienogest treatment was 6.3±3.4. The mean values at the sixth and twelfth months of dienogest therapy were 1.08±1.8 and 0.75±1.5, respectively (both p<0.001 compared to baseline). Conclusion: At the sixth and twelfth months of dienogest treatment a significant decrease in OMA size and reported pain scores were observed, whereas the AMH concentrations did not change significantly.

Direct embryonic biopsy with transcervical embryoscopy is an effective method for karyotyping and morphology assessment in miscarriages.

PURPOSE: The main purpose of this study is to compare the validity of transcervical embryoscopy method with standard uterine evacuation method in detecting more accurate karyotypes in miscarriages below tenth week of pregnancy. Additionally, the frequency and distribution of fetal morphological abnormality were evaluated. METHODS: A prospective study was carried out at the Gazi University Faculty of Medicine, Department of Obstetrics and Gynecology. Patients with missed abortions between sixth and tenth gestational weeks were included in the study group, and fetal morphological examination and direct embryonic biopsy were performed by transcervical embryoscopy. The control group consisted of patients who experienced miscarriage and genetic material obtained from routine uterine evacuation between February and October 2023. RESULT: A total of 60 patients in the study group and 189 patients in the control group were evaluated. The median ages, previous miscarriage numbers, median gravida numbers, and median gestational weeks were comparable between groups. Chromosomal abnormality was detected in 24 (42.8%) and 52 embryos (29.9%) in the study and control groups, respectively (p = 0.004). Culture failure rates were 6.6% (n = 4) and 7.9% (n = 15) in the study and control groups, respectively. In the study group, 12 embryos had a morphological abnormality in which 6 of them had normal karyotype. CONCLUSION: Direct embryonic biopsy with transcervical embryoscopy is an effective method to exclude maternal decidual cell contamination and placental mosaicism in miscarriages for karyotype analysis. In addition, detecting anomalies in morphology might contribute our understanding in the process of miscarriages which arises independent from structural/numerical chromosomal abnormalities.

Ethanol Sclerotherapy in the Management of Ovarian Endometrioma: Technical Considerations for Catheter- and Needle-Directed Sclerotherapy.

PURPOSE: To provide technical guidance on applying catheter-directed and needle-directed ethanol sclerotherapy for endometriomas and present the results of these sclerotherapy methods. MATERIALS AND METHODS: From January 2015 to March 2021, the results of the patients with symptomatic ovarian endometriomas who underwent needle-directed or catheter-directed sclerotherapy were evaluated, retrospectively. The decision to apply which sclerotherapy technique was made during the procedure for each patient considering the following factors: cyst size, cyst location, cyst viscosity, and tissue rigidity. RESULTS: Both needle-directed (n = 34 cysts) and catheter-directed (n = 34 cysts) sclerotherapy techniques were effective, with a 100% technical success rate and a 97% clinical success rate. In two of 34 cysts (6%) treated with needle-directed sclerotherapy, recurrence was detected and successfully retreated with catheter-directed sclerotherapy. Significant reductions in cyst size, pain, and serum cancer antigen 125 levels (p < 0.05) were noted. Serum anti-Müllerian hormone levels remained unaffected, indicating preserved ovarian reserve (p > 0.05). Among those treated for infertility, the pregnancy rate was 54% (n = 6/11). The mean ± SD cyst size decline was greater in catheter-directed sclerotherapy than needle-directed sclerotherapy (5.5 ± 3.1 cm vs. 4.0 ± 2.1 cm, p < 0.05). However, the pretreatment cyst volumes were considerably higher in catheter-directed sclerotherapy group (202.0 ± 233.5 mL vs. 78.8 ± 59.7 mL, p < 0.05) and were associated with significant post-treatment volume decrease (p < 0.05). CONCLUSION: The choice between catheter-directed and needle-directed ethanol sclerotherapy should be determined during the procedure, with a preference for catheter-directed sclerotherapy when feasible. Crucial factors in making this decision include cyst size, cyst location, cyst viscosity, and tissue rigidity. Level of evidence Level 3, non-controlled retrospective cohort study.

In vitro evaluation of exocytosis-associated SNARE molecules in human granulosa cells in polycystic ovary syndrome.

PURPOSE: Patients with polycystic ovarian morphology (PCOM) make up 20% cases for assisted reproductive technology (ART). Folliculogenesis is impaired in PCOS. Signaling molecules are involved in follicle development. Dysregulations of intrafollicular environment and signaling molecules are observed in PCOS. Granulosa cells (GCs) and oocytes secrete molecules into follicular fluid by exocytosis of SNAREs. The aim of this study is to evaluate vesicle transport and vesicle fusion proteins (SNAREs) in GCs from PCOS patients who have undergone IVF treatment. METHODS: Follicular fluids were collected from patients who undergo IVF/ICSI with the diagnosis of male factor (n = 10) and PCOS (n = 10) patients. GCs were separated and cultured. Each group of GCs was stimulated with FSH-hCG. The cells were examined under electron microscope. Immunofluorescent labeling was performed on cells for Stx6, SNAP25, StxBP1, FSHr, and KITL. Integrated density was analyzed from images of Stx6, SNAP25, StxBP1, FSHr, and KITL. RESULTS: Intercellular communication occurs by signal molecules; Stx6, SNAP25, and StxBP1 fusion proteins involved in exocytosis were decreased in the GCs of PCOS. There was no increase in in vitro stimulation with FSH-hCG either. In the electron microscope, it was observed that exocytosis of the vesicles was disrupted. CONCLUSIONS: Exocytosis and vesicular dynamics are among the basic physiological functions of human steroidogenic granulosa cells. Follicle development is necessary for production of competent oocytes and ovulation. Understanding the pathophysiology of PCOS at follicular level is important for disease management. According to our findings, deficits in vesicular dynamics of human granulosa cells in may be central to the treatment strategy for PCOS patients.

Preparation of the Endometrium for Frozen Embryo Transfer: A Systematic Review.

Despite the worldwide increase in frozen embryo transfer, the search for the best protocol to prime endometrium continues. Well-designed trials comparing various frozen embryo transfer protocols in terms of live birth rates, maternal, obstetric and neonatal outcome are urgently required. Currently, low-quality evidence indicates that, natural cycle, either true natural cycle or modified natural cycle, is superior to hormone replacement treatment protocol. Regarding warmed blastocyst transfer and frozen embryo transfer timing, the evidence suggests the 6th day of progesterone start, LH surge+6 day and hCG+7 day in hormone replacement treatment, true natural cycle and modified natural cycle protocols, respectively. Time corrections, due to inter-personal differences in the window of implantation or day of vitrification (day 5 or 6), should be explored further. Recently available evidence clearly indicates that, in hormone replacement treatment and natural cycles, there might be marked inter-personal variation in serum progesterone levels with an impact on reproductive outcomes, despite the use of the same dose and route of progesterone administration. The place of progesterone rescue protocols in patients with low serum progesterone levels one day prior to warmed blastocyst transfer in hormone replacement treatment and natural cycles is likely to be intensively explored in near future.

Double or dual stimulation in poor ovarian responders: where do we stand?

Recent advances in our recognition of two to three follicular waves of development in a single menstrual cycle has challenged the dogmatic approach of ovarian stimulation for in vitro fertilization starting in the early follicular phase. First shown in veterinary medicine and thereafter in women, luteal phase stimulation-derived oocytes are at least as competent as those retrieved following follicular phase stimulation. Poor ovarian responders still remain a challenge for many decades simply because they do not respond to ovarian stimulation. Performing follicular phase stimulation and luteal phase stimulation in the same menstrual cycle, named as double stimulation/dual stimulation, clearly increases the number of oocytes, which is a robust surrogate marker of live birth rate in in vitro fertilization across all female ages. Of interest, apart from one study, the bulk of evidence reports significantly higher number of oocytes following luteal phase stimulation when compared with follicular phase stimulation; hence, performing double stimulation/dual stimulation doubles the number of oocytes leading to a marked decrease in patient drop-out rate which is one of the major factors limiting cumulative live birth rates in such poor prognosis patients. The limited data with double stimulation/dual stimulation-derived embryos is reassuring for obstetric and neonatal outcome. The mandatory requirement of freeze-all and lack of cost-effectiveness data are limitations of this novel approach. Double stimulation/dual stimulation is an effective strategy when the need to obtain oocytes is urgent, including patients with malignant diseases undergoing oocyte cryopreservation and patients of advanced maternal age or with reduced ovarian reserve.

Subcutaneous luteal phase progesterone rescue rectifies ongoing pregnancy rates in hormone replacement therapy vitrified-warmed blastocyst transfer cycles.

RESEARCH QUESTION: Will luteal phase rescue with additional progesterone increase serum progesterone concentrations and improve reproductive outcomes in patients with low serum progesterone concentrations undergoing hormone replacement therapy (HRT) cycles? DESIGN: Case-control study including 40 consecutive patients with serum progesterone concentrations <8.75 ng/ml on the 5th day of progesterone supplementation who underwent rescue with a daily bolus of 25 mg s.c. progesterone, starting on the afternoon of the 5th day of progesterone administration. For every patient who underwent progesterone rescue, three patients matched by age, body mass index, number of previous attempts and number of blastocysts transferred, with serum progesterone concentration >8.75 ng/ml on the 5th day of progesterone administration served as controls (n = 120). The main outcome measure was ongoing pregnancy rate (OPR). RESULTS: Baseline demographic features and embryological data of the rescue and control groups were comparable. As expected, the mean serum progesterone concentration was lower in the rescue group on the 5th day of progesterone administration (7.84 ± 0.92 versus 15.32 ± 5.02 ng/ml; P < 0.001). Following rescue, the mean serum progesterone concentration on the day of vitrified-warmed embryo transfer (6th day of progesterone administration) was 33.43 ± 10.83 ng/ml (range 14.61-82.64 ng/ml), and the OPR of the rescue and control groups were comparable. CONCLUSIONS: In patients undergoing HRT vitrified-warmed blastocyst transfer with serum progesterone concentrations lower than 8.75 ng/ml 1 day prior to the scheduled embryo transfer (6th day of progesterone administration), additional supplementation with a 25 mg s.c. daily progesterone dose seems to rescue the cycle, resulting in OPR comparable to those of patients with serum progesterone >8.75 ng/ml.

Comparison of single euploid blastocyst transfer cycle outcome derived from embryos with normal or abnormal cleavage patterns.

RESEARCH QUESTION: To assess incidence of abnormal cleavage among biopsied blastocysts; to compare euploidy rates of the blastocysts with abnormal and normal cleavage; and to compare single euploid blastocyst transfer (SEBT) outcome derived from embryos with normal or abnormal cleavage. DESIGN: Retrospective analysis of prospectively collected data in a private IVF clinic. Consecutive 554 patients (749 cycles) undergoing preimplantation genetic testing for aneuploidy (n = 497; 671 cycles) or monogenic diseases (n = 57; 78 cycles) were included. All assessments for abnormal cleavage were carried out retrospectively; presence of abnormal cleavage was not a factor in deciding which euploid embryo to transfer. A total of 1015 blastocysts were biopsied and 295 SEBT procedures were carried out. Main outcome measure was live birth rate (LBR). RESULTS: Incidence of reverse cleavage, direct cleavage, and reverse plus direct cleavage, were 7.7%, 6.4% and 2.3%, respectively. Of the 1015 biopsied blastocysts, 35.0% were euploid. Blastocysts with abnormal cleavage, in total, had a significantly higher euploidy rate compared with blastocysts with normal cleavage (44.6% [74/166] versus 33.1% [281/849]; P = 0.017). The LBR after SEBT with normal, reverse and direct cleavage, and direct cleavage plus reverse cleavage, was 133/238 (55.9%), 6/26 (23.1%), 8/24 (33.3%) and 0/3 (0.0%) (P < 0.001). Generalized estimating equation analysis showed that the presence of abnormal cleavage pattern was the only independent predictor of LBR (OR 0.316; 95% CI 0.115 to 0.867; P = 0.013). CONCLUSIONS: Blastocysts with direct or reverse cleavage should be biopsied in preimplantation genetic testing cycles if they are morphologically eligible. Euploid blastocysts with abnormal cleavage, however, have approximately half the LBR of those euploid blastocyst with normal cleavage, hence, blastocysts with abnormal cleavage should have lower priority for transfer.

A new isolation and culture method for granulosa cells.

Granulosa cells are the cell population who have an increasing importance in the female genital system and reproduction. Thus, nowadays in vitro studies to address these cells are also gaining importance and attracts researcher's attention. The aim of our study is to develop a more feasible, low-cost granulosa cell isolation and culture method compared to methods defined so far. Granulosa cells were isolated from follicular fluids obtained from both healthy women donors (n = 19) and polycystic ovary syndrome (n = 15) applied to in vitro fertilization treatment process. Granulosa cells were isolated by using Lymphosep® separation fluid that was not used for this purpose before. The isolated cells were cultured in suitable culture dishes with a mixture of BIO-AMFTM-1 and DMEM/F12 in the first seeding and only complete DMEM/F12 in the following feeds. Complete medium contains only 5% fetal calf serum, 4% L-glutamine and 1% penicillin-streptomycin-amphotericin. The new methods we have developed in granulosa cell isolation and in vitro culture have been successful. Reduction in supplement types and amount; improved the proliferation rate of the granulosa cells in culture. Our new methods of isolation and cell culture for granulosa cells from healthy women, have been also successful in samples of polycystic ovarian patients. With these developed methods, granulosa cells, which belong to humans and have an important role in the ovary, could be isolated and subsequently be maintained to reproduce (proliferate) more easily and cheaper.

Menstrual Cycle Pain Is Independent of Ovulation in Adolescents With Primary Dysmenorrhea.

STUDY OBJECTIVE: This study aimed to evaluate the presence of anovulation in adolescents with primary dysmenorrhea (PD). DESIGN: Prospective cohort study. SETTING: Hacettepe University Children's Hospital, Adolescent Medicine outpatient clinic between September 2018 and September 2019. PARTICIPANTS: Healthy female adolescents (between 11 and 18 years of age), with regular menstruation with a score of 1-3 according to the Numerical Rating Scale (NRS) and grade 0 (no limitation for daily activities, no analgesic need and systemic symptoms) according to the Verbal Multidimensional Scoring System (VBSS) were recruited as a control group. The participants who met the diagnostic criteria for PD with an NRS score ≥4, had analgesic need in at least the last 3 menstrual cycles, had defined moderate-to-severe PD according to VMSS (Grade 2-3), and had analgesic need every time were accepted as the PD group. INTERVENTION AND MAIN OUTCOME MEASURES: For the determination of ovulation, suprapubic pelvic ultrasound and luteal SP levels were used. The first day of menstruation (DOM) was accepted as the first day of the menstrual cycle. The participants were called to the outpatient clinic for a total of 3 visits during 1 cycle; the first visit was for the suprapubic pelvic ultrasound imaging on the 12th-18th DOM, the second visit was for the first SP level measurement on the 21st-24th DOM, and the third visit was for the second SP level measurement on the 28th-31st DOM, if the next expected menstruation has not started yet. Participants' anthropometric measurements, menstrual history, family history of dysmenorrhea, and additional symptoms accompanying pain were recorded. RESULTS: Anovulatory cycle rates according to 2 different references for SP threshold values (3 and 5 ng/mL) were 31.7% and 36.6% in the PD group, and 44.4% and 55.6% in the control group, respectively (P = .250, P = .095). In the PD group, NRS scores were similar for the ovulatory and anovulatory cycles for both SP threshold values (P = .320, P = .205). When the reference value for SP threshold was accepted as ≥5 ng/mL, the NRS score was significantly higher in the ovulatory group (P = .0017). When the distribution percentages of SP levels were evaluated among all participants, the median value was 5.5 ng/mL. CONCLUSION: Contrary to classical information, anovulatory cycles are not rare in PD patients, and pain severity is at the same level in these cycles. The pathogenesis of PD in adolescents requires further study.

The impact of using culture media containing granulocyte-macrophage colony-stimulating factor on live birth rates in patients with a history of embryonic developmental arrest in previous in vitro fertilization cycles

Objective: To investigate the effect of using culture media containing granulocyte-macrophage colony-stimulating factor (GM-CSF) on embryological data and reproductive outcomes in patients with early embryonic developmental arrest. Material and Methods: Retrospective case-control study. A total of 39 patients, whose embryos were incubated with culture media containing GM-CSF due to embryonic developmental arrest in two previous in vitro fertilization (IVF) cycles in-between January 2016 and November 2017 at Hacettepe University IVF Center, were enrolled. Control group was generated among patients with first IVF attempts due to tubal factor in the same time period. All embryos in the control group were incubated with single step culture medium (without GM-CSF). For the control group selection, matching was done 1:2 ratio considering female age, body mass index, number of M-II oocyte retrieved, and number of embryo transferred (n=80). Results: Demographic features and embryological data were comparable between two groups. Number of fertilized oocytes (2-pronuclear) was 3.7±2.0 in GM-CSF group and 3.9±2.5 in the control (p=0.576). Overall, number of embryos transferred (1.3±0.5 vs 1.3±0.5, respectively) and blastocyst transfer rate (67.6% vs 59.2%, respectively; p=0.401) were similar. For the reproductive outcomes, implantation rate (32.3% vs 33.1%, respectively; p=0.937), clinical pregnancy rate (33.3% vs 32.5%, respectively; p=0.770), and live birth rate (25.2% vs 26.2%, respectively; p=0.943) were similar. Conclusion: Using GM-CSF-containing culture media in patients with two previous failed IVF attempts due to embryonic developmental arrest might rectify embryological data and reproductive outcomes. To make solid conclusion further randomized controlled trials are warranted.

Factors Related to Primary Dysmenorrhea in Turkish Women: a Multiple Multinomial Logistic Regression Analysis.

This study aimed to evaluate the factors related to the severity of menstrual pain in Turkish women with primary dysmenorrhea (PD). The study included 504 women with PD aged 18 years or older. A Visual Analogue Scale (VAS), a self-developed structured questionnaire, the International Physical Activity Questionnaire-Short Form (IPAQ-SF), State and Trait Anxiety Inventory, Beck Depression Inventory, and Nottingham Health Profile (NHP) were used to measure outcomes. Multiple multinomial logistic regression analysis was used to determine the factors related to the severity of menstrual pain. In this model, categorical menstrual pain severity levels (mild, moderate, and severe) were considered as dependent variables and the category of "severe menstrual pain" was determined as the reference category. p value less than 0.05 was considered statistically significant. The individuals were divided into 3 groups according to their VAS scores: mild-pain group (n = 132, 26.19%), moderate-pain group (n = 189, 37.50%), and severe-pain group (n = 183, 36.30%). BMI increase (OR = 1.10 and OR = 1.09), decreased chocolate consumption (OR = 1.88), menstruation duration (OR = 2.48) and menstrual pain duration (OR = 1.33 and OR = 1.61), and increased physical activity level (OR = 1.10) were found to increase the tendency to have less severe pain. The positive family history (OR = 0.35), a decrease in the age of menarche (OR = 0.47), the presence of irregular menstruation (OR = 0.36), and decreased quality of life (OR = 0.98 for NHP pain and emotional reaction) were found to be associated with a reduced likelihood of less severe pain (p < 0.05). In Turkey as well as in the rest of the world, PD is an important public health problem and many factors are associated with menstrual pain in Turkish women.

Addition of intramuscular progesterone to vaginal progesterone in hormone replacement therapy in vitrified-warmed blastocyst transfer cycles.

RESEARCH QUESTION: Does intramuscular progesterone supplementation ensure ongoing pregnancy rates (OPR) comparable with vaginal progesterone only in hormone replacement therapy cycles for vitrified-warmed embryo transfer; and is there a window of serum progesterone concentration out of which reproductive outcomes may be negatively affected? DESIGN: Retrospective longitudinal cohort study carried out at a single IVF clinic. In total, 475 consecutive, day-5 to day-6 vitrified-warmed embryo transfer cycles using hormone replacement therapy regimen were included. Vaginal progesterone only was given to 143 patients; supplementation of vaginal progesterone only with intramuscular progesterone supplementation every third day was given to 332 patients. On the sixth day of progesterone administration, immediately before frozen-thawed embryo transfer, circulating progesterone levels were measured. Main outcome measure was OPR. RESULTS: The baseline demographic features and embryological data of the vaginal progesterone only and intramuscular progesterone supplementation groups were comparable. The OPR were 48.3% and 51.8%, respectively (P = 0.477). Neither the circulating progesterone level nor the type of progesterone administration were independent predictors of OPR. The effect of serum progesterone levels on OPR was evaluated by percentiles (<10%, 10-49%, 50-90% and >90%), taking 50-90% as the reference sub-group. All percentiles in the intramuscular progesterone supplementation group and in the vaginal progesterone only group had similar OPR. CONCLUSIONS: Intramuscular progesterone supplementation every third day, overall, does not enhance OPR compared with vaginal progesterone only.

Ovarian hyperstimulation syndrome presenting with isolated unilateral right-side hydrothorax: A report of two cases and systematic review of the literature.

Although hydrothorax may accompany abdominal ascites in women with severe ovarian hyperstimulation syndrome (OHSS), there are few cases reported with isolated pleural effusion. Herein, we report two patients with isolated hydrothorax without any significant abdominal fluid following infertility treatment, along with a systematic review of the literature to describe risk factors for this rare entity. Two women with isolated pleural effusion without significant abdominal ascites were reported. The available literature was screened from Ovid-SP and PubMed to review OHSS cases with isolated hydrothorax. Two women aged 28 and 31 years were admitted to hospital with chest pain, tachypnea, and tachycardia after infertility treatment. They had right pleural effusion without abdominal fluid and the symptoms relieved after thoracentesis. Similar to our cases, we identified 24 case reports (n=41 women) in the literature according to eligible criteria. On the day of triggering, estradiol (E2) level was <4000 pg/mL in 81% of reported cases and hematocrit (HCT) was <45% in 44% of cases at the time of diagnosis. Isolated hydrothorax is an unpredictable event, which may even complicate women with low E2 levels or HCT concentrations. Physicians should keep in mind the possibility of isolated hydrothorax when respiratory symptoms are significant but abdominal ascites is not evident.

Anti-Müllerian hormone as a diagnostic tool for PCOS under different diagnostic criteria in an unselected population.

RESEARCH QUESTION: Is anti-Müllerian hormone (AMH) a valid tool to diagnose polycystic ovary syndrome (PCOS) according to different subsets of criteria among an unselected group of women? DESIGN: In this cross-sectional study, AMH concentrations were measured in an unselected group of women. The ability of AMH to diagnose PCOS according to National Institutes of Health (NIH), Rotterdam-2003 and Androgen Excess and PCOS Society (AE-PCOS) criteria was tested by using frozen serum aliquots (n = 392) that had been collected from a previous prevalence study of PCOS. RESULTS: The respective age and body mass index adjusted area under the curve (aAUC, 95% confidence interval) values were 0.80 (0.71-0.89), 0.74 (0.67-0.81) and 0.71 (0.64-0.79). When the definition of polycystic ovary morphology (PCOM) was set to an antral follicle count (AFC) of 20 instead of 12, the prevalence of syndrome dropped from 19.9% to 10.2% and from 15.3% to 8.9% according to Rotterdam-2003 and AE-PCOS criteria, respectively. In patients with Phenotype A, who had hyperandrogenism, ovulatory dysfunction and PCOM, AMH had an aAUC of 0.85 (0.77-0.92) to diagnose the syndrome. In Phenotypes B (hyperandrogenism + ovulatory dysfunction), C (hyperandrogenism + PCOM) or D (ovulatory dysfunction + PCOM), AMH had poor to fair ability to diagnose the syndrome. CONCLUSION: AMH has poor to fair validity to diagnose PCOS among an unselected group of women, except for patients bearing all features of the syndrome (Phenotype A). This finding is valid using the NIH, Rotterdam-2003 and AE-PCOS criteria and even after revising the definition of PCOM as AFC ≥20.

Bisphenol A and phthalate levels in adolescents with polycystic ovary syndrome.

Endocrine disruptors have been proposed in the etiology of polycystic ovary syndrome (PCOS) as they have the potency to interfere with hormone-sensitivity systems. The aim of this study was to evaluate the levels of bisphenol A (BPA) and phtalates in adolescents with PCOS. Sixty-two girls with PCOS and 33 controls, age 12-18 years were enrolled in the study. The diagnosis of PCOS was made using modified Rotterdam criteria. Urinary BPA levels were measured using high-performance liquid chromatography. Di-(2-ethylhexyl)-phthalate (DEHP), the most commonly used phthalate and mono-(2-ethylhexyl)-phthalate (MEHP), its main metabolite were measured by using high-performance liquid chromatography. Adolescents with PCOS had markedly increased BPA levels (15.89 µg/g creatine ± 1.16) when compared with the control group (7.30 µg/g creatine ± 1.38) (p = .016). In adolescents with PCOS, BPA was significantly correlated with polycystic morphology on ultrasound but not with obesity androgen levels, or other metabolic parameters. Patients with PCOS (DEHP: 0.40 ppm ± 0.24, MEHP: 0.13 ppm ± 0.23) and controls (DEHP: 0.49 ppm ± 0.27, MEHP: 0.14 ppm ± 0.3) had similar serum phtalate concentrations (p = .7 and p = .3, respectively). Exposure to specific endocrine disruptors such as BPA could modify neuroendocrine, reproductive, and metabolic regulation favoring PCOS development in adolescents.

PGT for aneuploidy does not affect three-cycle cumulative IVF discontinuation rate in women of advanced maternal age.

RESEARCH QUESTION: Does preimplantation genetic testing for aneuploidy (PGT-A) influence the discontinuation rate in women with advanced maternal age (AMA) undergoing IVF? DESIGN: Retrospective longitudinal cohort study carried out at a single IVF clinic in Turkey. In total, 401 consecutive AMA cases were included. Discontinuation rates of pre-intervention (conventional IVF; June 2013 to October 2014; 203 couples; 270 cycles) and post-intervention (PGT-A; April 2015 to June 2016; 198 couples; 285 cycles) periods were compared. To delineate the reason for discontinuation, a telephone survey was conducted. Primary outcome measure was cumulative discontinuation rate before completing three cycles of IVF treatment without achieving an ongoing pregnancy. RESULTS: The discontinuation rates after the first and second failed cycles were comparable between the two arms as were the cumulative discontinuation rates before completing three cycles. The cumulative ongoing pregnancy rate per embryo transfer was significantly higher in the PGT-A arm (43.2% versus 16.8%; P < 0.001). The cumulative ongoing pregnancy rate per patient was comparable between the two arms (20.7% versus 16.3%, respectively). Female age was the only significant contributor to treatment discontinuation (hazard ratio [HR] 1.07; 95% CI 1.09 to 1.13). Of the 296 couples discontinuing treatment in both arms, 179 (179/296 [60.5%]) participated in the survey; overall, psychological burden was the main reason for treatment discontinuation (37/179 [20.7%]). CONCLUSIONS: About 90% of AMA cases not achieving an ongoing pregnancy discontinue IVF treatment before completing three cycles. Discontinuation rate is not reduced by carrying out PGT-A. Female ageing is the only significant contributor, with a hazard of discontinuing further IVF treatment of 7% with female ageing of 1-year.
