RESUMO
Introduction: Concerning contemporary in-vitro fertilisation (IVF) practice, the use of frozen embryo transfer (FET) cycles has become more common than fresh transfers. Natural cycle (NC), programmed artificial cycle and mild stimulation cycle are primary endometrium preparation cycles. Monitoring serum progesterone levels in FET cycles are in the scope of current research focus. Low progesterone levels on the day of embryo transfer is presumed to negatively affect pregnancy outcomes, while progesterone supplementation may improve pregnancy rates. The purpose of our trial is to evaluate whether initiating subcutaneous (SC) progesterone supplementation on the day of embryo transfer when serum progesterone levels are below 10 ng/mL in tNC-FET will result in pregnancy rates comparable to those of patients with sufficient serum progesterone. Methods: Retrospective single centre study was conducted between August 2022 and April 2023 with 181 tNC-FETs. Patients were separated into groups according to serum progesterone concentrations (≥10 ng/mL and <10 ng/mL) on embryo transfer (ET) day. S.c progesterone (25 mg) was given on the day of ET when serum progesterone was <10 ng/mL, continuing until the 10th gestational week. Blood samples for pregnancy tests were collected 12 days after ET. Outcome parameters were pregnancy rate, clinical pregnancy rate (CPR), miscarriage rate, multiple pregnancy rate, biochemical pregnancy, and ongoing pregnancy rate (OPR). Results: About half (49.7%) had adequate progesterone concentrations (≥10ng/mL) on ET day. There was no significant difference between the groups regarding positive pregnancy test, OPR, multiple pregnancies, and miscarriage rates (57.8% versus 52.7%; 34.4% versus 29.7%, 1.1% versus 2.2%; 7.8% versus 5.5%; respectively, for progesterone concentrations on ET day ≥10 ng/mL and <10 ng/mL). With 55.2% of transfers leading to clinical pregnancy, significant differences emerged in biochemical pregnancy and CPR (3.3% vs 12.1%, P=0.02; 54.4% vs 40.7%, P=0.03, for ≥10 ng/mL and <10 ng/mL progesterone concentrations on ET day). Discussion: This study indicates that nearly half of the tNC-FETs may need luteal phase support due to low progesterone. However, 25 mc sc progesterone rescued the luteal support and yielded similar OPR as compared to normal progesterone group. Further studies are needed for understanding optimal progesterone levels, supplementation effectiveness, and potential benefits of earlier supplementation in FETs.

RESEARCH QUESTION: What should be the optimal route of luteal support in programmed frozen embryo transfer (FET) cycles? DESIGN: This was a randomized, parallel, phase IV pilot trial with three groups of women undergoing FET along with hormone replacement therapy for endometrial preparation at a tertiary private IVF centre (NCT03948022). Women with at least one autologous cryopreserved blastocyst were included. After preparing the endometrium with oestradiol, 151 women were randomly assigned to one of the following three progesterone arms before embryo transfer: oral (10 mg) dydrogesterone (DYD), total daily dose 40 mg (nâ¯=â¯52); 8% (90 mg) progesterone vaginal gel (VAG), total daily dose 180 mg (nâ¯=â¯55); or intramuscular progesterone (IMP) 50 mg/ml in oil, total daily dose 100 mg (nâ¯=â¯44). One or two vitrified-warmed blastocysts were transferred after 5 days' progesterone support. RESULTS: Baseline demographic features and embryological data were comparable among the groups. Ongoing pregnancy rates (40.4%, 38.2% and 45.5% in the DYD, VAG and IMP arms; Pâ¯=â¯0.76) and live birth rates (40.4%, 38.2% and 43.2% in the DYD, VAG and IMP arms, Pâ¯=â¯0.61) were statistically similar. Biochemical pregnancy rates and clinical miscarriage rates were also statistically similar among the groups. Significantly more patients with at least one side effect and moderate-to-severe side effects were documented in the IMP arm than the other groups (P < 0.001). CONCLUSIONS: Treatment with 40 mg/day oral DYD, 180 mg/day progesterone VAG gel or 100 mg/day IMP revealed similar reproductive outcomes in programmed FET cycles. Side effects were significantly more frequent in the IMP arm.

Factors that may have an effect on euploidy rate of blastocysts have been investigated thoroughly in the literature. We aimed to assess whether dual trigger alters the ploidy chance of a blastocyst in preimplantation genetic screening for aneuploidy (PGT-A) cycles. This retrospective cohort study was conducted in a total of 385 PGT-A cycles at a single tertiary center for various indications. Final oocyte maturation was triggered using human chorionic gonadotropin (hCG) or the combination of hCG and gonadotropin-releasing hormone agonists (GnRHa) (dual trigger). Participants were divided based on triggering method and all demographic and clinical characteristics of the patients were compared. Final oocyte maturation was triggered in 143 cycles with hCG (37.1%), and in 242 cycles with dual trigger (62.9%). The duration of stimulation was shorter in the dual trigger arm compared to the hCG trigger group (10.0 ± 1.6 vs. 9.4 ± 1.4 days, p ≤ .001). Euploidy rates per blastocyst tested were 23.4% and 26.1% respectively for hCG and dual trigger groups without significance. Similar rates of euploidy were noted, even after age stratification. There was no significant difference between the groups regarding positive pregnancy result and ongoing pregnancy rates (p = .779 vs. p = .188). Although dual triggering, compared to hCG triggering, does not provide an additional superiority on blastocyst euploidy rate, further studies in women with different infertility etiology are needed to specifically evaluate the impact of triggering method on ploidy rates.

A small proportion of infertile women experience repeated oocyte maturation abnormalities (OMAS). OMAS include degenerated and dysmorphic oocytes, empty follicle syndrome, oocyte maturation arrest (OMA), resistant ovary syndrome and maturation defects due to primary ovarian insufficiency. Genetic factors play an important role in OMAS but still need specifications. This review documents the spectrum of OMAS and to evaluate the multiple subtypes classified as OMAS. In this review, readers will be able to understand the oocyte maturation mechanism, gene expression and their regulation that lead to different subtypes of OMAs, and it will discuss the animal and human studies related to OMAS and lastly the treatment options for OMAs. Literature searches using PubMed, MEDLINE, Embase, National Institute for Health and Care Excellence were performed to identify articles written in English focusing on Oocyte Maturation Abnormalities by looking for the following relevant keywords. A search was made with the specified keywords and included books and documents, clinical trials, animal studies, human studies, meta-analysis, randomized controlled trials, reviews, systematic reviews and options written in english. The search detected 3,953 sources published from 1961 to 2021. After title and abstract screening for study type, duplicates and relevancy, 2,914 studies were excluded. The remaining 1,039 records were assessed for eligibility by full-text reading and 886 records were then excluded. Two hundred and twenty seven full-text articles and 0 book chapters from the database were selected for inclusion. Overall, 227 articles, one unpublished and one abstract paper were included in this final review. In this review study, OMAS were classified and extensively evaluatedand possible treatment options under the light of current information, present literature and ongoing studies. Either genetic studies or in vitro maturation studies that will be handled in the future will lead more informations to be reached and may make it possible to obtain pregnancies.
RESUMO
Although there is no known difference between the clinical manifestations of SARS-CoV-2 in pregnant and non-pregnant women based on the studies published until now, in vitro fertilization (IVF) treatments were suspended during the pandemic due to uncertainties with the suggestions of associated societies. However, we do not have enough data on the exact effects of SARS-CoV-2 on fertility and pregnancy and whether there are damaging effects on IVF outcome. There is no available evidence about the transmission of SARS-CoV-2 by either sexual way or through intrauterine insemination (IUI) or IVF. Up until now, there is no report to document the presence or absence of viral RNA in follicular fluid of SARS-CoV-2-positive women. In this paper, we present a case of oocyte retrieval from a SARS-CoV-2-positive woman and the search for viral RNA by polymerase chain reaction (PCR) in the follicular fluid aspirates.

OBJECTIVE: The aim of the study was to evaluate the effect of systemically administrated curcumin on the prevention of peridural fibrotic tissue and adhesion formation in a rat laminectomy model. METHODS: Thirty-two Wistar albino rats were randomly selected and equally divided into 4 groups as follows: negative control group (group I) did not undergo operation; positive control group (group II) underwent laminectomy without treatment; group III (low-dose curcumin; 100 mg/kg); and group IV (high-dose curcumin; 200 mg/kg). Curcumin was administered intraperitoneally per day for 7 days after surgery starting from day 0. Twenty-eight days after surgery, T12 and L4 vertebral columns, paraspinal tissues, and epidural scar tissue were dissected en bloc and prepared for histopathologic examinations. All specimens were examined for inflammation, epidural fibrosis (EF), foreign body reaction, medulla spinalis retraction, granulation tissue, and arachnoid involvement. A Kruskal-Wallis test followed by a Dunn multiple comparison test were used for statistical analysis, and a P value <0.05 was considered as statistically significant. RESULTS: Curcumin treatment significantly reduced inflammation, foreign body reaction, granulation tissue formation, medulla spinalis retraction, and EF formation compared with positive control group (P < 0.05); however, no significant differences were found between the 2 groups that received different doses of curcumin. CONCLUSIONS: The results of the present study showed that systemic administration of curcumin was effective in reducing EF formation, inflammation, granulation tissue formation, medulla spinalis retraction, and foreign body reaction in the laminectomy area. Our results suggest that antiinflammatory activities of curcumin are beneficial for attenuation of EF formation.

OBJECTIVE: Embryo quality assessment with morphological evaluation remains the first-line method of assessment to select the best embryo for transfer. We aimed to determine if an effect of poor quality embryos on good quality ones exists, whether by a paracrine effect or an adverse endometrial influence, when they are transferred together. MATERIALS AND METHODS: We included 412 couples, who underwent intracytoplasmic sperm injection (ICSI) cycles in a tertiary IVF center. Single embryo transfer with a good quality embryo and double embryo transfers with a good + poor quality embryo were evaluated. Overall pregnancy (PR) and live birth rates (LBR) were our main outcome measures. RESULTS: When PR and LBR are compared, there was no statistical significance between single embryo transfer (SET) and double embryo transfer (DET) groups (51.7 % vs 53.7 %, p = 0.620 and 47 % vs 43.1 %, p = 0.117). When the PR and LBRs were compared between SET from poor cohort and DET group, the outcomes were better in DET group (22.1 % vs 53.7 %, p < 0.001 and 22.1 % vs 43.1 %, p < 0.001). The PR and LBRs of SET from good cohort were significantly better than those of DET (64.4 % vs 53.7 %, p < 0.001 and 57.7 % vs 43.1, p < 0.001). When the PR and LBRs of SET from good cohort and SET from poor cohort were compared, better results were obtained in SET from good cohort. CONCLUSION: The addition of poor quality embryo even is of benefit to the LBR, in the setting of when there is only one good quality blastocyst available for the transfer.

OBJECTIVE(S): Cervical incompetence is an important cause of recurrent pregnancy loss, typically presenting in the second trimester with silent cervical dilation and premature delivery of the fetus. We aimed to evaluate the conception rate and time to conception or failure to conceive after preconceptional laparoscopic abdominal cerclage (LAC). STUDY DESIGN: We conducted this retrospective observational cohort study at a tertiary referral center. Patients who underwent LAC in the nonpregnant state for a second-trimester pregnancy loss between June 2012 and February 2020 were included. RESULTS: The subjects were 40 patients with a history of one or more second-trimester pregnancy losses despite the placement of vaginal cerclage, who had undergone LAC before contemplating a future pregnancy. The mean number of second-trimester pregnancy losses before LAC was two per woman. The ages of the women at the time of cerclage ranged from 21 to 42 years. The time to pregnancy, which was the primary outcome of the study, was determined as the number of menstrual cycles before the patient became pregnant after LAC and the number of cycles needed for the patient to achieve her latest pregnancy before LAC. Of the 40 women, 22.5 % were noted during the LAC operation to have a pelvic peritoneal pathology that might have affected fertility, and all such pathologies were treated concomitantly during the procedure. Spontaneous pregnancy rates before and after LAC were 96.4 % and 89.3 % (p = 0.299), and times to pregnancy before and after LAC were 6.3 ± 8.4 and 6.6 ± 8.1 cycles (p = 0.897). Neither difference was statistically significant. In more than 84 % of patients who became pregnant after LAC, pregnancy was sustained to the stage of viability. CONCLUSION(S): In patients with cervical incompetence, LAC is a very effective intervention to sustain pregnancy to the stage of viability. If placed during the preconceptional period, it does not delay achieving pregnancy and does not have a negative impact on the chances of conception. This may be reassuring to women undergoing this procedure before they achieve a pregnancy.

Background/aim: The aim of this study was to investigate the possible toxicity of the Ankaferd Blood Stopper (ABS) on the neural system. Materials and methods: Thirty Sprague Dawley rats were randomized into ABS (n: 15) and control (n: 15) groups. Following the anaesthetic induction, total laminectomy was performed to the lower thoracic, and upper lumbar areas in both groups and medulla spinalis was exposed. Two myelotomies were performed on the medulla spinalis. One millilitre ABS was applied to the incision site in the ABS group, and one millilitre 0.9% saline solution was applied in the control group. Rats were observed for 15 days regarding general behaviour, neurological signs, mobility, and signs of infection. Sixteen days later, all rats were decapitated under anaesthesia. Medulla spinalis was removed en bloc from all rats and was stained with Heamatoxylin & Eosin and luxol fast blue. Results: There was no significant difference between the ABS group and the control group regarding oedema, gliosis, the intensity of inflammatory cells, the presence of neuronal degeneration, neuron counts, and myelin degeneration. Conclusion: No clinical or histopathological evidence for the neurotoxic effect of the ABS was observed in the present study. Our findings might precipitate the use of ABS on human subjects regarding medulla spinalis surgery.

In vitro fertilization (IVF) involves controlled ovarian hyperstimulation using hormones to produce large numbers of oocytes. The success of IVF is tightly linked to the availability of mature oocytes. In most cases, about 70% to 80% of the oocytes are mature at the time of retrieval, however, in rare instances, all of them may be immature, implying that they were not able to reach the metaphase II (MII) stage. The failure to obtain any mature oocytes, despite a well conducted ovarian stimulation in repeated cycles is a very rare cause of primary female infertility, for which the underlying suspected genetic factors are still largely unknown. In this study, we present the whole exome sequencing analysis of a consanguineous Turkish family comprising three sisters with a recurrent oocyte maturation defect. Analysis of the data reveals a homozygous splice site mutation (c.1775-3C>A) in the zona pellucida glycoprotein 1 (ZP1) gene. Minigene experiments show that the mutation causes the retention of the intron 11 sequence between exon 11 and exon 12, resulting in a frameshift and the likely production of a truncated protein.

Background/aim: Cerebral vasospasm is a term that refers to prolonged, slowly progressing but reversible pathological narrowing of cerebral arteries occurring several days after subarachnoid hemorrhage (SAH), usually accompanied by a decrease in perfusion distal to the affected artery. Leptin is an endogenous polypeptide hormone that can be carried freely and bound to protein in the blood. Materials and methods: We investigated the superiority of topical application of leptin that may make a contribution to the development of new treatment modalities for unconscious patients in brain injury intensive care units and its preventive effect, which is considered to have multifactorial pathogenesis on cerebral vasospasm occurring after SAH via stereological studies of the basilar artery. Results: When mean serum leptin levels of the groups were compared, statistically significant differences were observed between the control and topical leptin-treated groups in favor of the treated groups with respect to serum leptin levels (P < 0.05). In the topical leptin-applied group, a significant difference in favor of vasodilatation was observed in the measurements of the basilar artery luminal area (P < 0.05). Conclusion: In accordance with the results, the topical administration of leptin can be used in the prevention of vasospasm, especially in unconscious patients with subarachnoid hemorrhage.
RESUMO
OBJECTIVE: To evaluate the association between progesterone elevation on the day of human chorionic gonadotropin (hCG) administration and clinical pregnancy rates of gonadotropin-releasing hormone (GnRH) antagonist in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles with the transfer of embryos at different developmental stages (day-3 versus day-5 ETs). MATERIAL AND METHODS: This is a retrospective analysis of fresh IVF/ICSI; 194 cycles out of 2676 conducted in a single center. RESULTS: A total of 2676 cycles were analyzed, of which 386 had no progesterone measurements available. Two hundred eighteen cycles had progesterone elevation (p>1.5 ng/mL) giving an overall incidence of 9.5%. Twenty-four cycles were excluded from further analysis. Of the remaining 194 cycles, 151 had day-3 transfers and 43 had blastocyst transfers. There was no statistically significant difference in pregnancy and clinical pregnancy rates per transfer between the D3-ET and D5-ET groups (46% vs. 49%, and 39% vs. 35%, respectively). CONCLUSION: The results of this study suggest that blastocyst transfer does not improve cycle outcomes compared with D3 transfer in GnRH antagonist cycles with an elevated progesterone level on the day of hCG.
RESUMO
Labial fusion usually affects prepubertal girls and postmenopausal women, it may rarely occurs in reproductive years in the absence of predisposing factors such as vulvar infections, dermatitis, trauma, female circumcision and lichen sclerosis. Should be considered in differential diagnosis in the differential diagnosis of urinary retention even if the patient doesn't have history of sexual intercourse.
RESUMO
OBJECTIVE: To see whether the oocytes retrieved from an ovary with an endometrioma would develop into embryos with aberrant timings of cleavage as assessed using time-lapse monitoring (TLM) and poorer morphologic quality compared with sibling oocytes from the contralateral ovary with no endometrioma in the same patient after intracytoplasmic sperm injection. METHODS: This was an observational prospective study at an in vitro fertilization (IVF) center of a private hospital. It included analysis and comparison of 128 embryos (69 embryos developed from the ovary with endometrioma and 59 embryos from the contralateral ovary without endometrioma serving as controls from a total of 20 women with infertility). Morphology of the embryo was assessed twice (days 3 and 5), again by capturing images with the TLM system. Morphokinetic parameters of embryos and clinical pregnancy rates were recorded separately from ovaries with and without endometrioma and were the primary outcomes of the study. Secondary outcomes included number of retrieved oocytes, number of metaphase II (MII) oocytes, fertilization rates, and conventional morphological classification of embryos. RESULTS: There were no differences in terms of the following time-lapse morphokinetic parameters of embryos. The mean numbers of oocytes and MII oocytes collected from the ovary with the endometrioma were similar to those collected from the contralateral ovary without endometrioma. Fertilization rates and the percentage of embryos with top morphologic quality were also similar. CONCLUSIONS: According to the morphokinetic parameters, this study further strengthens the notion that removal of endometriomas before IVF is not a necessity in terms of better oocyte quality and development.

BACKGROUND: Klinefelter syndrome (KS) is the most common sex chromosomal disorder in males and historically patients have been labeled as sterile. After the introduction of microdissection testicular sperm extraction (micro-TESE), successful sperm retrievals for intracytoplasmic sperm injection (ICSI) have been reported. MATERIALS AND METHODS: A retrospective study was undertaken on ten patients with non-mosaic KS undergoing micro-TESE for ICSI. The testicular volume and FSH and LH levels of each patient were measured. Karyotypes were confirmed by analyzing peripheral lymphocyte metaphases. Physical examination of the external genitalia was performed in all patients to rule out any co-existing anomaly. Micro-TESE was performed in order to investigate the presence of seminiferous tubules which may contain spermatozoa. When testicular spermatozoa were found in micro-TESE, ICSI was performed. Embryos were evaluated for further development. Fertilization was considered to have occurred after the visualization of the two pro-nuclei stage of the oocyte 24 hours after the intracytoplasmic injection of the motile spermatozoa. Pregnancy was confirmed by visualization of an intrauterine gestational sac under ultrasonographic examination. RESULTS: Testicular biopsy revealed motile spermatozoa in 6 of 9 patients (66.6 %). Fertilization rate per embryo-transfer was 40%. One patient was able to conceive and fathered a healthy boy weights 3410 g at the 39(th) week of gestation. CONCLUSION: Retrieval of testicular spermatozoa by micro-TESE is possible for azoospermic men with KS when assisted reproductive techniques are applied. For patients with KS who want to conceive, assisted reproductive techniques (ART) should be recommended.
RESUMO
UNLABELLED: The aim of this study was to measure circulating and intrafollicular concentrations of three inflammatory cytokines from women undergoing ovarian stimulation in order to determine their prognostic value in the outcome of intracytoplasmic sperm injection/embryo transfer cycles. MATERIALS AND METHODS: A total of 72 women following ovarian stimulation and intracytoplasmic sperm injection were included. Blood serum samples were drawn at the day of chorionic gonadotropin administration. Follicular fluids were collected at the day of oocyte retrieval. The total fractions of tumor necrosis factor alpha, interleukin (IL)-1beta and IL-6 were measured with commercially available immunoassays. RESULTS: The concentrations of IL-1beta, both in serum and follicular fluids, were significantly different between ICSI cycles that resulted in pregnancy and those that failed. The concentrations of the other two cytokines did not significantly differ between successful and unsuccessful cycles. CONCLUSION: The circulating and intrafollicular concentrations of IL-1beta seem to be related to the pregnancy outcome in ICSI cycles of healthy women.

OBJECTIVE: The aim of the study was to compare the outcome of pregnancies with cerclage placement in which cervical length was <15 mm and 15-25 mm. We further investigated the impact of cervical dilatation on delivery at <34 weeks. MATERIAL AND METHODS: Women with singleton gestations with cerclage placement due to cervical insufficiency were enrolled into the study. The data were collected prospectively between September 2004 and February 2009. We divided patients into two categories: (group I) cervical length below 15 mm, (group II) cervical length between 15-25 mm. We compared the pregnancy outcomes of the two groups and also analyzed the independent impact of cervical dilatation on delivery <34 weeks. RESULTS: The cervical cerclage group <15 mm had a similar incidence of preterm delivery <34 weeks gestation to the cerclage group 15-25 mm (p=0.4). No significant difference in rate of neonatal survival (p=0.6) was found between the two groups. Increased cervical dilatation in centimeters was found to be a significant predictor of delivery before 34 weeks gestation (OR: 3.4, 95% CI: 1.3-8.5, p=0.009). CONCLUSIONS: The extent of cervical shortening did not have a significant independent effect on the perinatal outcome of patients with cerclage placement. However, the presence of cervical dilatation prior to cerclage placement in cases of cervical insufficiency may worsen perinatal outcomes by increasing the rate of delivery before 34 weeks.
RESUMO
Transient osteoporosis of pregnancy is a rarely observed skeletal pathology developing in the last months of pregnancy. Meticulous evaluation is important for the differential diagnosis of severe and progressive hip and/or groin pain in pregnant patients. MRI is a valuable and safe technique for demonstrating bone marrow edema and skeletal abnormalities during pregnancy. Avoidance of vaginal delivery and non-weight bearing measures are essential in order to prevent complications such as hip fractures related to transient osteoporosis of pregnancy. We present the diagnostic evaluation and treatment of an uncommon case of transient osteoporosis of pregnancy with resolution of symptoms and postpartum.
RESUMO
Multifetal pregnancy reduction (MFPR) offers a therapeutic option which reduces the maternal, prenatal, neonatal morbidity and mortality associated with multifetal pregnancies. In certain cases of MFPR, where difficulty is encountered in reaching the thorax due to the fetal position as well as the location of membranes and placenta, an alternative approach may be the insertion of the needle to the fetal cranium. We describe a new technique for MFPR performed by fetal intracranial injection of potassium chloride. To our knowledge, the current case series is the first report describing the technique of intracranial injection of potassium chloride during MFPR and selective termination. This approach enables a technically easier procedure than the intrathoracic approach. However, the use of this technique should be reserved for selected cases of MFPR only by experienced operators and centers.
