Sperm Donors' Identity Disclosure: Is It REALLY Crucial? For Whom?

OBJECTIVE: To study the preference of sperm donors with identity disclosure (ID) versus anonymous donors (AD) and to understand if this selection affects clinical outcomes in an Israeli population. METHODS: This retrospective study included patients who chose imported sperm donation during 2017-2021. Of these, 526 used their own (autologous) oocytes and 43 patients used donated oocytes (DO). The primary endpoint was the type of chosen donor with ID versus AD. We examined the tendency toward ID according to demographic parameters and the theoretical impact of donor-type selection on reproductive outcome and compared patients who performed cycles with autologous oocytes with those using DO. RESULTS: Single women had a significantly higher probability of choosing sperm donors with ID than heterosexual couples (55.6% vs. 33.3%, OR 2.5, CI 95% 1.52-4.11, P < 0.001). Although not significant, same-sex couples were more likely to choose sperm donors with ID than heterosexual couples (49.1% vs. 33.3%, OR 1.93, CI 95% 0.97-3.85, P = 0.06). Sperm donor samples, 2501 vials, were imported. It was performed 698 intra-uterine insemination and 812 in vitro fertilization cycles were performed, respectively, resulting in 283 pregnancies without differences between patients who chose sperm donors with ID versus AD sperm. No significant differences were observed regarding the option for sperm donors with ID between patients using DO (44.2%) and those using autologous oocytes (51.3%). CONCLUSION: While ID is important for a certain section (mainly single) of recipients, it is far from the only dominant factor during donor selection. Sperm donation type does not impact clinical outcomes.

Israeli students' perceptions regarding sperm donation: dilemmas reflections with dominant demographic effect.

BACKGROUND: Sperm donation has undergone significant medical and social transformations in recent decades. This study aimed to explore Israeli students' perceptions towards sperm donation and investigate the potential influence of demographic characteristics on these perceptions. DESIGN: The study encompassed 254 students from Tel-Aviv University, who completed an anonymous online survey in January-February 2021. This cross-sectional quantitative online survey, comprised 35 questions categorized into three sections: demographic data, assessment of prior knowledge, and perceptions of sperm donation (general perceptions related to both positive and negative stigmas associated with sperm donation, the roles and activities of sperm banks, and considerations surrounding identity disclosure versus the anonymity of sperm donors and their offspring). RESULTS: Participants exhibited a relatively low level of prior knowledge (mean 31.2 ± 19 of 100). Scores for positive and negative stigmas ranged from 1.3 to 2.2. Notably, the statement "Donors' anonymity preservation is crucial to maintain sperm donation" received a mean of 3.7. Seeking for anonymous sperm donation identity both by recipients and offspring was ranked with low means (1.5 and 1.7, respectively). However, the pursuit of half-siblings by mothers or siblings themselves received higher ratings ranging from 2.7 to 3. Women's stigma ranking were notably lower, while men emphasized the importance of donor anonymity. CONCLUSIONS: Sperm Banks hold a position of medical authority rather than being perceived as being commercial entity. The preservation of donor anonymity is widely accepted as a crucial element, prioritized over the requests for identity disclosure from recipients and offspring. Demographic parameters exhibit a strong and precise effects on participants' perceptions.

Day 3 embryo assessment does not provide a reliable prediction for blastocyst formation and designation: a retrospective cohort study.

Although many Fertility Centers have adopted day 5 or 6 embryo transfer policy, yet, 30% of embryo transfers in the US are performed on day 3. This is mainly due to concerns related to longer embryo culture effect and higher rates of embryo transfer cancellation on day 5, with no effect on cumulative pregnancy rate. We conducted a retrospective cohort study comparing individual embryo transfer order rank, best embryo for fresh transfer and intention to freeze, of day-3 and day-5 embryos based on their morphology score. Day-3 embryos of each patient were ranked by embryologists for the order of transfer and intention to freeze, based on morphological score, blinded to actual blastulation outcome. The corresponding blastocysts were similarly ranked for the order of transfer and vitrification intention. Ranking was compared to test the predictive value of day-3 morphological assessment. Sixty patients with 784 day-3 embryos were included. There was only a moderate positive significant correlation between ranks on day-3 and ranks on day-5 [r = 0.662 95% CI (0.611-0.706, p < 0.001)]. Only 25% of the best embryos for transfer on day 3 (rank = 1) were chosen for fresh transfer on day 5. A total of 441 embryos were intended to be frozen on day 3. Of those, 201 were not transferred nor vitrified on day 5-6 (45%), 3.35 embryos per patient. No significant difference was found between average day-3 rank of embryos ranked 1, 2 (3.12 vs 4.12, p = 0.074) and 3 (3.12 vs 4.08, p = 0.082) on day-5-6. To conclude, this study brings a different perspective to the comparison of day 3 and day 5 by following each embryo's putative and actual designation. Day-3 ranking of embryo morphology did not provide a reliable prediction for blastocyst formation, transfer order and vitrification intention, and may support transfer or cryopreservation of blastocysts over cleavage stage embryos.

Cryopreserved testicular spermatozoa among patients with azoospermia.

PURPOSE: To investigate cryopreserved testicular spermatozoa among patients with azoospermia. METHODS: In this retrospective study spanning from October 1993 to December 2021, we examined men diagnosed with azoospermia who underwent testicular spermatozoa cryopreservation. Data from medical records included utilization and disposal of sperm samples, age at initial cryopreservation. We analyzed the data over 20 years using Kaplan-Meier curves, compared age with the log-rank test, and assessed hazard ratios (HR) with 95% confidence intervals (CI) using Cox regression analysis. RESULTS: A total of 356 patients with a mean age of 32.1 ± 6 were included. Of these, 225 patients utilized thawed testicular sperm for fertility treatments, with 118 patients using all their frozen straws and 107 patients partially using their stored straws. Additionally, 29 patients opted for disposal (six patients partially used their testicular spermatozoa before disposal), resulting in 108 patients who neither used nor disposed of their straws. From a laboratory standpoint, nearly 90% of patients contributed a single testicular sample, which was subsequently divided and cryopreserved as straws, with a median of 4 straws per sample. Notably, in the older age group (> 35 years old), there were a significantly lower usage rate and a higher disposal rate compared to the younger age groups (p < 0.05 for both), corroborated by univariable Cox analysis. CONCLUSIONS: This extensive study unveils unique patterns in the preservation and disposal of testicular spermatozoa among azoospermic patients. Most patients utilize a significant portion of their stored samples, while older patients tend to use their testicular spermatozoa less frequently.

Fallopian tube catheterization under 3D vaginal ultrasound guidance followed by highly selective hysterosalpingo-foam sonography: an outpatient procedure.

PURPOSE: To describe the feasibility of our preliminary outpatient fallopian tube catheterization procedure under 3D vaginal ultrasound (US) guidance followed by highly selective hysterosalpingo-foam sonography (HyFoSy) in infertile women diagnosed with proximal tubal obstruction. MATERIALS AND METHODS: A prospective trial was conducted from October 2022 to December 2023. 3D vaginal US was used to establish the precise location of the tip of the selective salpingography catheter at the tubal ostium. A roadrunner was used to cannulate the occluded portion of the fallopian tube. After tubal cannulation, ExEm foam was injected under direct US guidance to confirm tubal recanalization and its passage through the fallopian tubes. RESULTS: During the study period, a total of 14 women with proximal tubal occlusion underwent this procedure. Tubal patency was obtained in 92.8%. No immediate and remote complications were observed. To date three (21.4%) of the patients conceived after tubal catheterization and one had a live birth. CONCLUSION: Outpatient fallopian tube catheterization under 3D vaginal US guidance followed by selective HyFoSy can be successfully implemented for the diagnosis and treatment of patients with proximal tubal occlusion. The 3D modality enables volume capture of the required acquisitioning and the subsequent post imaging analysis permitting further examination and study. Additional experience is needed to consolidate the feasibility of this innovative procedure and identify the patient subgroups that would benefit the most from this approach.

[THE EFFECT OF ETHNICITY ON THE AGE OF SINGLE PATIENTS APPLYING FOR SPERM DONATION].

INTRODUCTION: Sperm banks have shifted from assisting heterosexual couples with male infertility to primarily serving single women and female couples through medical services, reflecting advances in fertility treatments and societal changes. AIMS: Evaluate demographic changes among single women who have applied for sperm donation during 30 years in the State of Israel. METHODS: This retrospective cohort study includes 4265 single women who received sperm donation between January 1992 and December 2021, at a tertiary medical center. We divided the follow-up period into 6 groups of 5 years each. A comparison was made of the demographic characteristics of single women applying for sperm donation in different periods according to: 1) age at the beginning of the treatment; 2) ethnic origin - 7 ethnic groups. RESULTS: The average age of single women who received sperm donation was 38.2±4.4 years. The average age of patients decreased from 39.58 years in 1997-1992 to 38.08 years in 2017-2021 (p-value<0.05). Ashkenazic Jews (38.4%) and Sephardic Jews (37.7%) were the most common ethnic origins among single women, with Arab women comprising only 0.2%. Single Jewish women of Ashkenazi descent seek sperm donation treatment almost a year earlier than their Sephardic counterparts (Arab countries and North Africa). CONCLUSIONS: Single Israeli women opting for early sperm donation carries significant clinical, social, and economic implications. Women from conservative social backgrounds appear to be less inclined to seek sperm donation as single individuals or tend to delay this option until a later age, in contrast to women from liberal backgrounds.

Treatment safety of ART cycles with extremely high oestradiol concentrations using GnRH agonist trigger.

RESEARCH QUESTION: Are IVF treatments with extremely high peak oestradiol levels and gonadotrophin releasing hormone (GnRH) agonist trigger associated with higher complication rates? DESIGN: A retrospective cohort study including patients from two large medical centres treated between 2019 and 2021. A study group with extremely high peak oestradiol levels (≥20,000 pmol/l on the day of ovarian stimulation, or ≥15,000 pmol/l on the previous day) and a control group with normal range oestradiol levels (3000-12000 pmol/l) that received GnRH agonist triggering. Patients were surveyed about complaints and medical care related to ovum retrieval and medical files were reviewed. Major complication rates and the need for medical assistance were compared. RESULTS: Several differences between the study and control group were observed because of the study design: mean age was 33.01 ± 5.14 versus 34.57 ± 4.52 (P < 0.001), mean peak oestradiol levels was 26645.34 ± 8592.57 pmol/l versus 7229.75 ± 2329.20 pmol/l (P < 0.001), and mean number of oocytes were 27.55 ± 13.46 versus 11.67 ± 5.76 (P < 0.001) for the study and control group, respectively. Major complications and hospitalization rates were similar between the study and control groups (three [1.25%] versus one [0.48%]; P = 0.62 and three [1.25%] versus two [0.96%]; P = 1.0, respectively). Thirty-six patients (15.1%) in the study group and 11 (5.3%) in the control group sought medical care after retrieval, mostly due to abdominal pain, without the need for further workup or hospitalization (P < 0.001). CONCLUSIONS: Extremely high oestradiol levels were not associated with thromboembolic events, higher major complication or hospitalization rates, and therefore may be considered safe. Nevertheless, patients may be informed of possible higher rates of discomfort, mostly abdominal pain. Larger studies are warranted to confirm our results.

Critical Demographic Changes among Sperm Donation Recipients Over Three Decades.

BACKGROUND: Sperm banks initially focused on providing sperm donation (SD) to heterosexual couples grappling with severe male infertility. Notable advancements in fertility treatments and sociological trends have broadened the scope of SD toward single women and same sex female couples. OBJECTIVES: To evaluate SD recipient characteristics over the last three decades in Israel according to demographic parameters. METHODS: This retrospective cohort study included 5489 women who received SD between January 1992 and December 2021 from a tertiary referral center. We divided the overall period into six groups of five years each. A comparison of demographic characteristics of women who received SD in different periods was performed according to age at the beginning of the treatment, marital status (single women and same sex female couples, heterosexual couples), and ethnic origin. RESULTS: The average age of women who received SD was 37.02 ± 5.36 years. The average patient age rose from 35.08 years in 1992-1997 to 37.43 years in 2017-2021 (P-value < 0.01). The use of SD was more common among single women and same sex female couples compared to heterosexual couples in later years. Regarding single and same sex female couple, the percentage of SD recipients increased radically from 33% to 88.1% (P-value < 0.01). CONCLUSIONS: Modern sperm banks treat older patients in non-heterosexual relationships. These trends encompass not only medical implications (e.g., in vitro fertilization vs. intrauterine insemination) but also delve into the personal and sociological impact experienced by both patients and offspring.

IVF under COVID-19: treatment outcomes of fresh ART cycles.

STUDY QUESTION: Does prior severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection in women undergoing fertility treatments affect the outcomes of fresh ART cycles? SUMMARY ANSWER: SARS-CoV-2 infection does not affect fresh ART treatment outcomes, except for a possible long-term negative effect on oocyte yield (>180 days postinfection). WHAT IS KNOWN ALREADY: A single previous study suggested no evidence that a history of asymptomatic or mild SARS-CoV-2 infection in females caused impairment of fresh ART treatment outcomes. STUDY DESIGN, SIZE, DURATION: Retrospective cohort study, including all SARS-CoV-2 infected women who underwent fresh ART cycles within a year from infection (the first cycle postinfection), between October 2020 and June 2021, matched to non-diagnosed controls. PARTICIPANTS/MATERIALS, SETTING, METHODS: Patients from two large IVF units in Israel who were infected with SARS-CoV-2 and later underwent fresh ART cycles were matched by age to non-diagnosed, non-vaccinated controls. Demographics, cycle characteristics and cycle outcomes, including oocyte yield, maturation rate, fertilization rate, number of frozen embryos per cycle and clinical pregnancy rates, were compared between groups. MAIN RESULTS AND THE ROLE OF CHANCE: One hundred and twenty-one infected patients and 121 controls who underwent fresh ART cycles were included. Oocyte yield (12.50 versus 11.29; P = 0.169) and mature oocyte rate (78% versus 82%; P = 0.144) in all fresh cycles were similar between groups, as were fertilization rates, number of frozen embryos per cycle and clinical pregnancy rates (43% versus 40%; P = 0.737) in fresh cycles with an embryo transfer. In a logistic regression model, SARS-CoV-2 infection more than 180 days prior to retrieval had a negative effect on oocyte yield (P = 0.018, Slope = -4.08, 95% CI -7.41 to -0.75), although the sample size was small. LIMITATIONS, REASONS FOR CAUTION: A retrospective study with data that was not uniformly generated under a study protocol, no antibody testing for the control group. WIDER IMPLICATIONS OF THE FINDINGS: The study findings suggest that SARS-CoV-2 infection does not affect treatment outcomes, including oocyte yield, fertilization and maturation rate, number of good quality embryos and clinical pregnancy rates, in fresh ART cycles, except for a possible long-term negative effect on oocyte yield when retrieval occurs >180 days post-SARS-CoV-2 infection. Further studies are warranted to support these findings. STUDY FUNDING/COMPETING INTEREST(S): None. TRIAL REGISTRATION NUMBER: 0010-21-HMC, 0094-21-ASF.

Tubal patency assessment using sequential transvaginal ultrasound and hysterosalpingo-foam sonography after methotrexate treatment for tubal pregnancy.

RESEARCH QUESTION: What is the efficacy of sequential two-dimensional transvaginal ultrasound (2D-US) and hysterosalpingo-foam sonography (HyFoSy) after methotrexate (MTX) treatment for tubal pregnancy among patients who desire a future pregnancy? DESIGN: A prospective trial conducted between May 2019 and November 2020. Patients who had a suspected tubal ectopic pregnancy diagnosed by ultrasound and treated by MTX were included. These patients underwent sequential transvaginal 2D-US assessment of the pelvic organs and a complementary HyFoSy for tubal patency. The primary outcome was tubal obstruction in the affected side. RESULTS: A total of 360 women underwent sequential transvaginal 2D-US assessment of the pelvic organs and a complementary HyFoSy for tubal patency. Of these, 40 (11.1%) women fulfilling the inclusion criteria were enrolled. In six out of 40 (15%), hydrosalpinx of the affected tube was found during the initial transvaginal ultrasound examination and were excluded from further investigation. In the remaining 34 (85%) patients, HyFoSy was carried out. Tubal block was found in 10 out of 34 (29.4%) patients. Of these, eight out of 34 (23.5%) and two out of 34 (5.9%) had a proximal block of the affected tube and bilateral proximal obstruction, respectively. Hysterosalpingography confirmed the tubal obstruction in all the affected cases. No procedure-related complications were documented. CONCLUSIONS: Forty per cent of women who were treated by MTX for tubal pregnancy were diagnosed with tubal obstruction. We recommend that sequential transvaginal ultrasound and HyFoSy become part of routine follow-up for these women, thus offering them timely referral to the appropriate specialist.

Similar but different: A comparison of rare site ectopic pregnancies.

OBJECTIVES: A comparative examination of the clinical, laboratory, ultrasound findings, and operative characteristics of rare site located ectopic pregnancies. METHODS: Retrospective analysis of all department cases of rare site located ectopic pregnancies diagnosed and treated from December 2006 to December 2019. RESULTS: Thirty rare ectopic pregnancies were identified. Of these, 11 were ovarian, 10 were interstitial and 9 were tubal stump. The patients treated for ovarian pregnancy had significantly lower human chorionic gonadotropin (hCG) levels than patients treated for interstitial or stump pregnancies (2025 ± 1105 mIU/ml, 18,424 ± 2579 mIU/ml and 11,204 ± 9221 mIU/ml, respectively, p = 0.003). The main presenting symptom in patients with an ovarian pregnancy was abdominal pain (90.9%, 60.0% and 44.4%, respectively, p = 0.031). Signs of abdominal peritoneal irritation (i.e., rebound tenderness and guarding) were more frequent upon physical examination in patients with an ovarian pregnancy (72.2%, 30.0% and 22.2%, respectively, p = 0.044) who also exhibited the highest rates of syncope and hypovolemic shock upon admission compared to patients with an interstitial or stump pregnancy (54.5%, 10.0% and 11.1%, respectively, p = 0.031). Ovarian pregnancies were associated with the lowest sonographic detection rates (9.1%, 80.0% and 100%, respectively, p = 0.0001) and with free fluid in the pouch of Douglas (72.7%, 20.0% and 22.2%, respectively, p = 0.02). Ovarian pregnancies experienced the highest rupture rate during surgery compared to interstitial or stump pregnancies (66.9%, 16.7% and 44.4%, respectively, p = 0.028), had a significantly higher estimated blood loss (1081 ± 647 ml, 760 ± 597 ml and 343 ± 318 ml, respectively, p = 0.003) and required blood transfusions in the perioperative period (63.6%, 20.0% and 11.1%, respectively, p = 0.025) significantly more often. CONCLUSIONS: Ovarian pregnancy remains the most challenging diagnosis compared to interstitial and tubal stump ectopic's. Health care providers should recognize these rare site ectopic pregnancies and to handle these gynecological emergencies promptly.

The impact of past COVID-19 infection on pregnancy rates in frozen embryo transfer cycles.

PURPOSE: To study the effect of SARS-CoV-2 infection on pregnancy rates in frozen embryo transfer (FET) cycles. METHODS: A retrospective cohort study including women under the age of 42 with documented SARS-CoV-2 infection up to 1 year prior to treatment, undergoing FET cycles in the first half of 2021, with transfer of embryos generated prior to the infection. Controls were SARS-CoV-2 non-diagnosed, non-vaccinated women matched by age, number, and day of embryo transfer. Demographic and cycle characteristics and outcomes were compared. RESULTS: Forty-one recovered women and 41 controls were included. Pregnancy rates were 29% and 49% respectively (p = 0.070). Stratification by time from SARS-CoV-2 infection to transfer into ≤ 60 and > 60 days revealed a difference in pregnancy rates, with women in the COVID group having lower pregnancy rates if infected in proximity to the transfer (21% vs. 55%; p = 0.006). In a logistic regression model, infection was a significant variable (p = 0.05, OR 0.325, 95% CI 0.106-0.998). Logistic regression applied on the subgroup of women infected in proximity to the transfer further strengthened the univariate results, with COVID-19 remaining a significant parameter (p = 0.005, OR 0.072, 95% CI 0.012-0.450). CONCLUSIONS: In FET cycles of patients with past SARS-CoV-2 infection, in which oocytes were retrieved prior to infection, decreased pregnancy rates were observed, specifically in patients who recovered less than 60 days prior to embryo transfer. Pending further studies, in cases of FET cycles with limited number of embryos, postponing embryo transfer for at least 60 days following recovery from COVID-19 might be considered when feasible.

What can we learn about posthumous sperm retrieval after extra long-term follow-up?

PURPOSE: To describe spermatozoa extraction rate by testicular sperm extraction (TESE) for posthumous sperm retrieval (PMSR) and examine harvest time impact on sperm motility; to compare long-term sperm usage between married vs. single deceased men. METHODS: This retrospective study included all PMSR cases in Shamir Medical Center during 2003-2021. We evaluated sperm cryopreservation according to latency time after death. Then, we assessed sperm usage according to Israeli PMSR regulations. RESULTS: The study included 69 (35 married and 34 singles) deceased men with average age of 30.3 ± 7.8 years. Sperm was cryopreserved in 65 cases (94.2%) after maximum and average harvest time of 40 and 16.5 ± 8.1 h, respectively. Motile sperm extraction was associated with significantly shorter harvest time compared with non-motile sperm (13.8 ± 7.3 vs. 18.7 ± 8.1 h, p = 0.046). Sperm usage among married deceased was significantly higher than single (15.6% vs. 0%, p = 0.05). Disposal requests were lower among single compared to married men relatives without reaching statistical difference. Eventually, single men had significantly higher rate of non-used cryopreserved samples (93.8% vs 69.6%, p = 0.01). CONCLUSION: This large long-term cohort study demonstrates high efficacy of PMSR. We found significant harvest latency time difference between motile and non-motile preserved sperm. Clinical sperm usage rate justifies the efforts for PMSR among married deceased. However, contradicting policy on the topic of single men (which implies liberal sperm preservation but rigid prevention of usage) results with high non-used sperm rate and relatives' extremely sophisticated emotional burden.

Endometrial compaction is associated with increased clinical and ongoing pregnancy rates in unstimulated natural cycle frozen embryo transfers: a prospective cohort study.

PURPOSE: To investigate the association between endometrial compaction and pregnancy rates in unstimulated natural cycle frozen embryo transfers. DESIGN: A single-center prospective cohort study. Endometrial thickness by transvaginal ultrasound and blood progesterone levels on the day of ovulation and the day of embryo transfer were evaluated in patients undergoing natural cycle frozen embryo transfer. Compaction was defined as > 5% decrease in endometrial thickness between ovulation day and day of transfer. Clinical and ongoing pregnancy rates in cycles with and without compaction were compared. RESULTS: Seventy-one women were included, of which 44% had endometrial compaction, with similar rates when subdividing the patients by day of transfer (day 3 or day 5). Clinical and ongoing pregnancy rates were higher in the compaction group compared to the non-compaction group (0.58 vs. 0.16, P < 0.001; 0.52 vs. 0.13, P < 0.001 respectively). Subdividing by degree of compaction > 10% and > 15% revealed similar pregnancy rates as > 5%, with no added benefit to higher degrees of compaction. CONCLUSIONS: About half the patients in our study undergoing unstimulated natural cycle frozen embryo transfer experienced compaction of the endometrium, occurring as early as day 3 post-ovulation. This was significantly correlated with increased clinical and ongoing pregnancy rates.

Obstetric, neonatal and child development outcomes following assisted hatching treatment: a retrospective cohort study.

Assisted hatching (AH) involves artificial disruption of the zona pellucida prior to embryo transfer. The purpose of this study is to examine the safety of AH technique and its effect on obstetrical, perinatal and neonatal outcomes and risk of developmental delay. This is a retrospective cohort of ART cycles using laser AH technique. The study group consisted of 120 cases of AH cycles resulting in singleton pregnancies and live births compared with 113 control cases. A current phone questionnaire was conducted to assess child development in the first year of life. AH was not associated with increased risk for all obstetrical and perinatal outcomes examined including PPROM, gestational diabetes, hypertensive diseases of pregnancy, delivery by cesarean section, gestational age at delivery, low birth weight (LBW), preterm birth and neonatal Apgar score (p>.05). No significant differences were observed between AH and control group in rates and risk of congenital malformations (5.8 vs. 4.4%, respectively, OR 1.33, 95% CI 0.41-4.34) and developmental delay (19.2 vs. 12.8%, respectively, OR 1.62, 95% CI 0.74-3.52). AH did not increase the risk of obstetrical and neonatal complications in singleton pregnancies, including congenital malformations and child developmental delay. AH may therefore be considered a safe method of ART.

Hysterosalpingo-Foam Sonography for the Diagnosis of Tubal Occlusion: A Systematic Review and Meta-analysis.

This systematic review and meta-analysis evaluated the diagnostic accuracy of hysterosalpingo-foam sonography in suspected cases of tubal occlusion. The combined sensitivity and specificity estimates were 0.99 (95% confidence interval [CI], 0.89-0.99) and 0.91 (95% CI, 0.53-0.98), respectively, with positive and negative likelihood ratios of 11.5 (95% CI, 1.5-87.5) and 0.006 (95% CI, 0.0003-0.12), respectively. The diagnostic odds ratio was 1931.008 (95% CI, 69.7-53,460.8). These findings confirm hysterosalpingo-foam sonography as a highly accurate test for the diagnosis of tubal occlusion and show that it is on a par with standard tests.

Fertility patients under COVID-19: attitudes, perceptions and psychological reactions.

STUDY QUESTION: What are the perceptions of infertility patients and the factors correlating with their psychological distress, following suspension of fertility treatments during the Corona Virus Disease-19 (COVID-19) pandemic? SUMMARY ANSWER: Most patients preferred to resume treatment given the chance regardless of background characteristics; higher self-mastery and greater perceived social support were associated with lower distress, while feeling helpless was associated with higher distress. WHAT IS KNOWN ALREADY: Infertility diagnosis and treatment frequently result in significant psychological distress. Recently published data have shown that clinic closure during the COVID-19 pandemic was associated with a sharp increase in the prevalence of anxiety and depression among infertile patients undergoing IVF and was perceived as an uncontrollable and stressful event. Personal resources play an important protective role in times of crisis, helping reduce levels of distress. STUDY DESIGN, SIZE, DURATION: This cross-sectional questionnaire study included patients whose fertility treatment was suspended following the COVID-19 pandemic, in a tertiary hospital. The survey was delivered to 297 patients within 12 days at the beginning of April 2020. PARTICIPANTS/MATERIALS, SETTING, METHODS: The self-administered questionnaire included items addressing: (i) patients' demographic characteristics, (ii) anxiety related to COVID-19 infection risk and level of social support, (iii) patients' perceptions of the new guidelines and description of subsequently related emotions and (iv) two validated scales assessing levels of emotional distress and self-mastery. Multivariate analysis was conducted to assess factors alleviating or increasing emotional distress during the COVID-19 pandemic. MAIN RESULTS AND THE ROLE OF CHANCE: There were 168 patients who completed the survey, giving a response rate of 57%. Study variables in the regression model explained 38.9% of the variance in psychological distress experienced by patients during treatment suspension. None of the background characteristics (e.g. age, marital status, parity, economic level or duration of treatments) had a significant contribution. Feeling helpless following the suspension of treatments was associated with higher distress (P < 0.01). Higher self-mastery and greater perceived social support were associated with lower distress (P < 0.01). Despite the ministry of health's decision, 72% of patients wished to resume treatment at the time of survey. LIMITATIONS, REASONS FOR CAUTION: This was a cross-sectional study, thus information about patients' characteristics prior to the COVID-19 pandemic was not available. The length and implications of this pandemic are unknown. Therefore, the ability to draw conclusions about the psychological consequences of the crisis is limited at this point of time. WIDER IMPLICATIONS OF THE FINDINGS: Personal resources play an important protective role in times of crisis, helping to reduce levels of distress. Study findings suggest that attention should be paid to strengthening and empowering patients' personal resources together with directly confronting and containing feelings of helplessness. In line with the European Society for Human Reproduction and Embryology (ESHRE) guidelines, especially at this time of high levels of distress, it is imperative to offer emotional support to reduce stress and concerns. Furthermore, as the pandemic is stabilizing, resumption of treatment should be considered as soon as appropriate according to local conditions. STUDY FUNDING/COMPETING INTEREST(S): This study was funded by the IVF unit of the Shamir Medical Center. All authors declare no conflicts of interest. TRIAL REGISTRATION NUMBER: N/A.

Triggering method in assisted reproduction alters the cumulus cell transcriptome.

RESEARCH QUESTION: How does the choice of triggering final oocyte maturation affect the cumulus cell transcriptome? DESIGN: Sixty patients undergoing gonadotrophin-releasing hormone antagonist (GnRH-ant) IVF cycles were recruited for this nested case-control study. Patients were stratified into three subgroups based on their ovarian reserve (high, normal and low). Triggering final oocyte maturation was accomplished by either single trigger (with human chorionic gonadotrophin [HCG] only or gonadotrophin-releasing hormone agonist [GnRH-ag] only) or dual trigger combining HCG and GnRH-ag. The choice of trigger was at the discretion of the treating physician. Within each group patients receiving a dual trigger were matched by demographic and pre-stimulation parameters with patients receiving a single trigger. The matching was performed to minimize the biological variability within each subgroup. Thirty patients were included in the final analysis. Cumulus cells were stripped away from the retrieved oocytes. Cumulus cells from three sibling oocytes were pooled, the RNA extracted and libraries prepared. Next-generation sequencing was performed on all samples. RESULTS: Dual triggering supports key ovarian pathways of oocyte maturation and extracellular matrix remodelling, while attenuating vasculo-endothelial growth and providing antioxidant protection to the growing follicles. CONCLUSIONS: This is the first study to delineate key transcriptomic changes under dual triggering of final oocyte maturation, across different patient populations. The findings underline the need for larger-scale studies validating transcriptomic effects of methods for triggering final oocyte maturation. Furthermore, there is a need for large-scale clinical randomized controlled studies to relate the findings of this study with clinical outcomes.

Does double trigger (GnRH-agonist + hCG) improve outcome in poor responders undergoing IVF-ET cycle? A pilot study.

Many strategies are offered for the treatment of poor responders. However, no compelling advantage for one stimulation protocol over another has been hitherto established. In this study, we aimed to evaluate the role of different modes and timings of final follicular maturation trigger, on in vitro fertilization (IVF) cycle outcome of poor responder patients. In the present randomized controlled study, poor responder patients, according to the Bologna criteria, undergoing controlled ovarian hyperstimulation (COH) using the gonadotropin-releasing hormone (GnRH) antagonist protocol were randomly assigned to three different final follicular maturation trigger modes and timings: hCG 36 h before oocyte pick-up (OPU) (hCG trigger); GnRH agonist (GnRHag) 36 h before (OPU) and hCG on day of OPU (GnRHag trigger); and GnRHag and hCG, 40 and 34 h prior to OPU, respectively (double trigger). Pregnancy rate, number of oocytes, and top quality embryos (TQEs). Thirty-three poor responder patients were recruited and randomized to the different study groups. While there were no in-between groups' differences in patients' demographics and stimulation variables, patients in the double trigger group had a significantly higher number of TQE (1.1 ± 0.9 vs. 0.3 ± 0.8 and 0.5 + 0.7; p<.02) as compared to the hCG trigger and the GnRH-ag trigger groups, respectively, with an acceptable pregnancy rate. Double trigger offers an additional benefit to poor responder patients. Larger studies are required to support this new concept prior to its implementation to IVF practice.
