Ionophore application for artificial oocyte activation and its potential effect on morphokinetics: a sibling oocyte study

Abstract Purpose To evaluate whether ionophore application at the oocyte stage changes the morphokinetics of the associated embryos in cases of artificial oocyte activation. Methods In a prospective sibling oocyte approach, 78 ICSI patients with suspected fertilization problems had half of their MII-oocytes treated with a ready-to-use ionophore (calcimycin) immediately following ICSI (study group). Untreated ICSI eggs served as the control group. Primary analyses focused on morphokinetic behavior and the presence of irregular cleavages. The rates of fertilization, utilization, pregnancy, and live birth rate were also evaluated. Results Ionophore-treated oocytes showed a significantly earlier formation of pronuclei (t2PNa) and a better synchronized third cell cycle (s3) (P < .05). The rate of irregular cleavage was unaffected (P > .05). Ionophore treatment significantly improved the overall rates of fertilization (P < .01) and blastocyst utilization (P < .05). Conclusion Ionophore application does not negatively affect cleavage timing nor is it associated with irregular cleavage.

BackgroundCurrently, in China, only women undergoing in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles can donate oocytes to others, but at least 15 oocytes must be kept for their own treatment. Thus, the aim of this study was to determine whether oocyte donation compromises the cumulative live birth rate (CLBR) of donors and whether it is possible to expand oocyte donors’ crowd.MethodsThis was a retrospective cohort study from August 2015 to July 2017 including a total of 2,144 patients, in which 830 IVF–embryo transfer (IVF-ET) patients were eligible for oocyte donation and 1,314 patients met all other oocyte donation criteria but had fewer oocytes retrieved (10–17 oocytes). All 830 patients were advised to donate approximately three to five oocytes to others and were eventually divided into two groups: the oocyte donation group (those who donated) and the control group (those who declined). The basic patient parameters and CLBR, as well as the number of supernumerary embryos after achieving live birth, were compared. These two factors were also compared in all patients (2,144) with oocyte ≥10.ResultsIn 830 IVF-ET patients who were eligible for oocyte donation, only the oocyte number was significantly different between two groups, and the donation group had more than the control group (25.49 ± 5.76 vs. 22.88 ± 5.11, respectively; p = 0.09). No significant differences were found between the two groups in other factors. The results indicate that the live birth rate in the donation group was higher than that in the control group (81.31% vs. 82.95%, p = 0.371), without significance. In addition, CLBR can still reach as high as 73% when the oocyte number for own use was 10. Supernumerary embryos also increased as the oocyte number increased in all patients (oocyte ≥10).ConclusionsCurrently, oocyte donation did not compromise CLBR, and oocyte donation can decrease the waste of embryos. In addition, in patients with 10 oocytes retrieved, the CLBR was still good (73%). Thus, it is possible to expand oocyte donors if the number of oocyte kept for own use was decreased from 15 to 10 after enough communication with patients.

Cumulative Live Birth

Abstract Study question Does the addition of calcium ionophores for artificial oocyte activation(AOA) help in improving Cumulative Live Birth Rate in surgically retrieved sperms for male factor infertility? Summary answer AOA significantly improved cumulative live birth rate in Micro-TESE (M-TESE), TESA for non- azoospermia (TESTICULAR) and Non-Obstructive Azoospermia(NOA)-TESA but not in Obstructive Azoospermia (OA)-TESA. What is known already The main cause of Total Fertilization Failure after ICSI is thought to be due to oocyte activation deficiency (OAD) because of oocyte-related or sperm-related factors. Studies have shown that artificial oocyte activation (AOA) is helpful in these situations, but is most effective in couples who have clear sperm-related OAD. Oocyte activation, by Phospholipase- C- Zeta (PLCζ) present in the sperm, leads to series of events resulting in calcium oscillation, oocyte activation and fertilization. AOA increases the free intracellular calcium thereby mimicking physiologic cell signaling mechanisms that result in oocyte activation and fertilization. Study design, size, duration This is a retrospective cohort study done in an academic private ART center, in which patient’s records were analyzed, from January 2016 to December 2019 (total 4 years’ duration) and all ICSI cycles with surgically retrieved sperms were included (n = 365). Study subjects were divided into 4 groups- M-TESE (n = 143), NOA-TESA (n = 38), OA-TESA (n = 62) and TESTICULAR (n = 92). Subdivision was done into cases if AOA was done and control were with conventional ICSI without AOA. Participants/materials, setting, methods Method- Immediately after ICSI, in case group (AOA), all metaphase II oocytes were treated with calcium ionophore (GM508- CultActive) for 15 minutes, then thoroughly washed and incubated under standard conditions. Primary outcome measured was cumulative live birth rate(CLBR) and Secondary outcomes were fertilization rate (Fert. rate), Cleavage rate, clinical pregnancy rate (CPR) and miscarriage rate (MA). Statistical analysis was performed with Chi-square and Mann-Whitney- U test, with significance at P < 0.05. Institutional committee clearance was obtained. Main results and the role of chance The CLBR was significantly higher with AOA- M-TESE (55.8% vs 33.3%, p- 0.008), AOA-NOA-TESA (55.55% vs 15%, p- 0.027) and AOA-TESTICULAR (62.9% vs 32.3%, p- 0.006) group. Fert. rate was significantly higher with AOA-M-TESE (81 ± 0.84 vs 64 ± 0.97, p- 0.001), AOA-NOA-TESA (86 ± 0.76 vs 64 ± 0.13, p- 0.001) and AOA-TESTICULAR (72 ± 0.12 vs 57 ± 0.11, p- 0.001). Cleavage rate, CPR also showed similar significant differences while MA was comparable. However, significant differences were not observed in any of the outcome measured in OA-TESA group between cases and controls - CBLR (51.6% vs 41.9%, p- 0.611), Fert.rate (0.77±0.14 vs 0.75±0.11, p- 0.539), CPR and MA, p- value > 0.05. It may be hypothesized that surgically retrieved sperms in cases of NOA or non- azoospermia where TESTICULAR sperms are taken have reduced or absent capacity to cause Calcium oscillations due to deficient or inadequate PLCζ or there may be some chromatin level abnormalities in these sperms, leading to lesser fertilization and lesser good quality embryos in control group in which AOA was not done. Limitations, reasons for caution This study is retrospective in nature. Sibling oocytes were not compared. The study neither looked at obstetrics complication nor the neonatal outcomes. Further studies are required for long term impact on children born from AOA cycles. Wider implications of the findings: To our knowledge, this is the first study in the literature evaluating the efficacy of calcium ionophores for NOA (M-TESE, TESA), OA (TESA) and TESTICULAR sperms. Further research is needed for use of calcium ionophores in cases of unexplained infertility and recurrent implantation failure. Trial registration number Not applicable

This study aimed to investigate the effects of estrogen in combination with aspirin and intrauterine balloon on the uterine endometrial repair and reproductive prognosis in patients after surgery for severe intrauterine adhesion (sIUA). We prospectively recruited 114 patients with sIUA. Intrauterine device (IUD) was placed and oral estrogen was administered after surgery. Patients were divided into control group and aspirin group. In addition, patients in aspirin group were subdivided into nonballoon group and balloon group. Results showed that, after therapy, the increase in endometrial thickness of aspirin groups was superior to control group (P<0.05). The scores of intrauterine adhesion and menstruation were significantly improved in balloon group as compared to nonballoon group and control group, and significant differences were also observed between nonballoon group and control group (P<0.05). Of 97 patients, 44.3% became pregnant after surgery, the live birth rate was 27.8%, and the miscarriage rate was 37.2%, but there were no significant differences among three groups (P>0.05). Thus, aspirin may promote the uterine endometrial growth and repair after surgery for sIUA, and IUD in combination with intrauterine balloon may reduce the recurrence of intrauterine adhesion, but their effect on the reproductive prognosis is required to be further studied.

Objective. To investigate the effect of dehydroepiandrosterone (DHEA) on the outcome of in vitro fertilization (IVF) in patients with endometriosis (EMT). Methods. Female patients diagnosed with EMT in our hospital from May 2018 to May 2019 were selected. The patients were divided into the control group (n = 22) and the DHEA group (n = 22) according to the random number table. Patients in the control group received placebo and patients in the DHEA group received DHEA. Patients in both groups received either DHEA (25 mg) or placebo orally 3 times a day for 90 days from the first day of menstruation. Patients were subsequently treated with an IVF cycle. In the control group, 22 patients completed the first cycle and 13 patients completed the second cycle. In the DHEA group, 22 patients completed the first cycle and 11 patients completed the second cycle. Serum sex hormone levels including serum E2 on hCG day, mean progesterone on hCG day, FSH on day 2, AMH on day 2, and gonadotropin dose were determined using a chemiluminescent immunoassay kit. The number of antral follicles of the bilateral ovaries was counted by transvaginal B-ultrasound, and the maximum length and transverse diameter of the ovaries were measured at the same time, to calculate the average diameter of the ovaries, observe the morphology of endometrium, and measure the thickness of the endometrium. The implantation rate, clinical pregnancy rate, persistent pregnancy rate, and live birth rate were compared between the two groups. Results. There were no significant differences in serum E2, progesterone, endometrial thickness, recovered oocytes, mean number of transferred embryos, and mean score of leading embryo transfer between the DHEA group and the women who completed the first and second cycles ( P > 0.05 ). The AMH, antral follicle count, serum E2 on hCG day, the number of recovered oocytes, fertilized oocytes, and the fertilization rate in the DHEA group were higher than those in the control group ( P < 0.05 ). The doses of FSH on day 2, COH on day 3, and gonadotropin were lower than those in the control group ( P < 0.05 ). There was no significant difference in the total number of embryos, the number of high-quality embryos, and the number of transplanted embryos between the two groups ( P > 0.05 ). The implantation rate, clinical pregnancy rate, persistent pregnancy rate, and live birth rate in the DHEA group were higher than those in the control group ( P < 0.05 ). Conclusion. DHEA can significantly increase serum E2 level and improve IVF outcome by regulating the hormone synthesis process, thus improving oocyte and embryo quality.

Abstract Background: Ovarian hyperstimulation syndrome (OHSS) is a common disease during controlled ovarian hyperstimulation treatment. However, the obstetric and neonatal outcomes of this group of patients are unknown. The aim of this study was to explore the effects of late moderate-to-critical OHSS on obstetric and neonatal outcomes.Methods: This prospective observational study included 17,537 patients who underwent IVF/ICSI-fresh embryo transfer (ET) between June 2012 and July 2016 and met the inclusion criteria, including 7,064 eligible patients diagnosed with clinical pregnancy. Ultimately, 6,356 patients were allocated to the control group, and 385 patients who were hospitalized and treated at the center for late moderate-to-critical OHSS were allocated to the OHSS group. Then, propensity score matching analysis was performed, matching nine maternal baseline covariates and the number of multiple gestations; 385 patients with late moderate-to-critical OHSS were compared with a matched control group of 1,540 patients. The primary outcomes were the live birth rate, preterm delivery rate, miscarriage rate, gestational age at birth (weeks), obstetric complications and neonatal complications.Results: The duration of gestation in the matched control group was significantly higher than that in the OHSS group. The live birth delivery rate did not significantly differ between the OHSS and matched control groups. The incidence rates of the obstetric complications venous thrombosis (VT) and gestational diabetes mellitus (GDM), neonatal complications and the number of neonates admitted to the NICU were significantly higher in the OHSS group than in the matched control group.Conclusions: Pregnant women undergoing IVF with fresh ET whose course is complicated by late moderate-to-critical OHSS appear to experience shortened gestation and increased obstetrical and neonatal complications compared with matched controls whose course is not complicated by OHSS. However, the live birth rate, average neonatal weight, and incidence rates of premature delivery, miscarriage, early abortion, hypertensive disorder of pregnancy (HDP), placenta previa (PP), intrahepatic cholestasis of pregnancy (ICP), and low neonatal birth weight (LBW) did not differ significantly between the two groups.

Uterine Adenomyosis

Abstract Study question Is adenomyosis associated with worse clinical and perinatal outcomes in ovum donation cycles? Summary answer Adenomyosis was associated with reduced live birth rate per embryo transfer but not with increased risk of miscarriage or worse perinatal outcomes than controls. What is known already The effect of adenomyosis on IVF/ICSI outcomes are controversial as studies addressing this issue are limited in number and heterogeneous. Conclusions withdrawn from previous works differ regarding the prospective or retrospective design of the study. Two different metanalysis conducted showed that adenomyosis reduced implantation and clinical pregnancy rate and increased miscarriage risk. However, current data regarding perinatal outcomes of assisted reproduction techniques cycles in patients diagnosed with uterine adenomyosis is scarce. Study design, size, duration A retrospective cohort study in which 3307 patients undergoing ovum donation cycles were included. Patients who underwent single embryo transfer (SET) between years 2018 and 2019 were included and divided into two groups: adenomyosis (n = 179) and controls (n = 3218). Participants/materials, setting, methods Inclusion criteria consisted of patients in an oocyte donation program who had fresh SET on day 5 blastocyst stage development. Patients diagnosed with miomas and/or severe endometriosis and those who had undergone previous uterine surgical interventions were excluded from the study. Cases consisted of patients with a history of either focal or diffuse adenomyosis diagnosed via transvaginal ultrasonography (TVUS). Main results and the role of chance Clinical pregnancy rate per embryo transfer was 82/179 (45.8%) in those women diagnosed with adenomyosis versus 1869/3218 (59.8%) in control group (OR = 0.57 95% CI. 0.41–0.78, p < 0.001). Miscarriage rate was similar in the two study groups and differences found were not statistically significant, being 15/82 (18.3%) for adenomyosis and 309/1869 (16.5%) for control group. A lower live birth rate per embryo transfer was observed in women diagnosed with adenomyosis versus control, being 68/179 (38%) and 1560/3128 (49.9%) respectively (OR = 0.615 95% CI 0.44–0.85, p = 0.002). There were no statistically significant differences between childbirth delivery methods (vaginal versus caesarean section). Furthermore, means of gestational age at the time of delivery, newborn size and weight and incidences of low birth weight, preterm birth and admission in neonate intensive care unit (NICU) did not differ between the two groups. In addition, IVF and perinatal outcomes were similar in patients with diffuse adenomyosis compared to focal adenomyosis. Limitations, reasons for caution This is an observational study and thus possible confounders cannot be completely excluded. Diagnostic of adenomyosis is complex and, despite imaging via TVUS is both sensitive and specific, different criteria may be combined in order to fully assess the diagnostic. Wider implications of the findings: Published literature has described how adenomyosis negatively impacts clinical outcomes in ART cycles; however, data regarding perinatal results is scarce. This study is of interest as it provides a first insight for clinicians showing that adenomyosis affects clinical but not perinatal outcomes in ovum donation cycle.

Abstract Study question What live birth rate do we see when we use testicular sperm in ART for non-azoospermic couples after at least one previous failed cycle? Summary answer In our cohort of couples 24% had a live birth using testicular sperm and therefore was not higher than national average ART rates. What is known already There is increased interest in using testicular sperm in assisted reproduction technology (ART) to improve outcomes after previous failed cycles. Mehta et al. reported results of a 50% live birth rate using testicular sperm in the first cycle for couples with oligospermia and a history of failed cycles with ejaculated sperm. We aim to audit our results in a similar population of couples. Study design, size, duration St Peters Andrology Centre in London, United Kingdom completed 128 surgical testicular sperm retrievals reviewed between the two-year period of 2018–2019. We conducted a retrospective audit of their paper-based records to identify those couples with injectable sperm on their semen analysis and who had previous cycles attempts using ejaculated sperm. Participants/materials, setting, methods We identified 27 couples who underwent testicular sperm extraction despite having an ejaculated semen analysis with injectable sperm and at least one previous failed cycle. A systematic review of their paper and electronic medical record was conducted to assess live birth rates and fertilization rates from ART. Main results and the role of chance Couples had an average male age of 41 (range 31–60) and an average female age of 38 (range 30–45). The men had an average serum testosterone of 15 nmol/L (range 8–35 nmol/L) and an average serum FSH of 8.9 IU/L (range 1.7–30 IU/L). 59% (n = 17) of men had a DNA fragmentation index completed with an average score of 41% (range 31%–51[Y1]%). In the women the mean serum anti-Müllerian hormone (AMH) was 15.8 pmol/l (range 1–64 pmol/l). With ejaculated sperm the fertilization rate was 59% (95% CI [27%, 59%]) and blastocyst conversion rate was 43% (95% CI [50%, 69%]). There was no statistical significance with testicular sperm where the fertilization rate was 58% (95% CI [51%, 65%]) and blastocyst conversion rate was 54% (95% CI [40%, 67%]). Overall, there were 7 clinical pregnancies in this population of couples. Of these clinical pregnancies, 2 miscarried and 5 progressed to a live birth. This audit yielded a live birth rate per cycle of 15% and a live birth rate per couple of 24%. Limitations, reasons for caution Limitations of the study are low number of patients and absence of a control group. Wider implications of the findings: We recommend caution and further analysis going forward using testicular sperm in ART where ejaculated sperm in available.

Ovarian Cystectomy

Abstract Introduction For patients considering undergoing assisted reproductive techniques (ART), many concerns arise when persistent ovarian cysts are found. This large study aimed to determine how ovarian cyst removal affects success rates of IVF/ICSI therapies. Methods 550 patients who underwent an IVF/ICSI treatment between 2002 and 2011 with a persistent ovarian cyst ≤ 5 cm before treatment were analyzed retrospectively. 328 patientsʼ preference was to undergo a laparoscopic cystectomy and 222 patients opted for a conservative management. Control subjects included 13 552 patients undergoing IVF/ICSI at the same period of time without an ovarian cyst. Results After adjusting for age, patients with ovarian cysts without surgery needed a significant higher stimulation dose than the control group (2576.4 vs. 2207.5 IU, p < 0.001). However, on average, they had 1.13 (− 0.25 – 2.01) higher oocyte number retrieved compared to the operated patients (9.0 ± 5.5 vs. 8.2 ± 5.0) (p = 0.012). Patients after surgical cyst removal had a significant lower number of oocytes retrieved (MNOR) in comparison to the control group (8.2 ± 5.0 vs. 9.5 ± 5.4) (p = 0.00). Compared to controls, operated patients had similar clinical pregnancy rate (CPR) (34.2 vs. 33.5%) OR 1.031 (95% CI 0.817 – 1.302) (p = 0.815). Compared to controls, patients without surgery showed significant lower pregnancy rate (34.2 vs. 25,7%) OR 1.428 (95% CI 1.054 – 1.936) (p = 0.002) and lower live birth rate (LBR) (21.9 vs. 13.5%) OR 1.685 (95% CI 1.143 – 2.485) (p = 0.008). Conclusions Ovarian cystectomy did not negatively impact the pregnancy rate or the live birth rate compared to controls.

Day 3 Embryos

Background: Embryo quality is an important predictor of successful outcome in in vitro fertilization (IVF). However, current knowledge on the live birth rate after transfer of poor quality embryos is limited. This study investigated the live birth rate after transfer of only poor quality day-3 embryos in women undergoing IVF. Methods: This retrospective study included 153 couples who underwent IVF at IVFMD, My Duc Hospital, Ho Chi Minh City, Vietnam between June 2014 and January 2017 and had only poor quality day-3 embryos available for fresh (n [Formula: see text] 102) or frozen (n [Formula: see text] 51) transfer. The control group included patients who had transfer of one good embryo (n [Formula: see text] 64). Embryos were rated using the Istanbul criteria. Results: In the poor quality embryo group, the mean number of oocytes retrieved and number of embryos were 7.5 ± 4.4 and 1.8 ± 0.9, respectively. Mean number of embryos transferred was 1.6 ± 0.5 in the fresh transfer group and 2.0 ± 0.2 in the freeze-only group. Live births did occur after transfer of poor quality embryos, but the implantation, clinical pregnancy and live birth rates were significantly lower than after fresh or frozen transfer of a single good quality embryo (9.5 vs. 26.6%, p < 0.001; 13.7 vs. 26.6%, p < 0.001; and 7.2 vs. 18.8%, p [Formula: see text] 0.02, respectively). Conclusions: Live birth was achieved after transfer of only poor quality embryos in women undergoing IVF. This suggests that transfer of poor quality embryos could be an option when higher grade embryos are not available, after the chances of live birth have been discussed with the patient.
