Abstract
STUDY QUESTION Is early rescue ICSI (E-RICSI) an effective and safe technique compared to conventional ICSI? SUMMARY ANSWER Despite the higher multi-pronucleus (PN) rate compared to conventional ICSI, E-RICSI did not add extra risks to clinical and neonatal outcomes. WHAT IS KNOWN ALREADY Based on the finding that the second polar body was released in 80% of fertilized oocytes by 4 h after exposure to spermatozoa and in ∼90% of fertilized oocytes by 6 h, E-RICSI brings forward the timing of rescue ICSI to 6 h after initial insemination, and effectively prevents oocyte aging and embryo-uterus asynchrony. However, some researchers still voice concerns about the efficacy and safety of E-RICSI, and comparative studies are limited. STUDY DESIGN SIZE DURATION A retrospective cohort study was conducted on patients who underwent conventional ICSI or E-RICSI treatment between January 2015 and December 2020 at a university-affiliated hospital. Using 1:1 propensity score matching, 1496 cases entered each group. PARTICIPANTS/MATERIALS SETTING METHODS In total, 1496 couples undergoing conventional ICSI oocyte retrieval cycles and 1496 undergoing E-RICSI oocyte retrieval cycles were enrolled in this study, and basic clinical characteristics, embryologic data, clinical outcomes and neonatal data were compared between groups. The embryos in the E-RICSI group were divided into two subgroups: those fertilized by iIVF (IVF subgroup) and those fertilized by E-RICSI (E-RICSI subgroup); the embryologic data, clinical outcomes, and neonatal data for these subgroups were also compared with the conventional ICSI group. Logistic regression was used for statistical analysis with potential confounder adjustment. MAIN RESULTS AND THE ROLE OF CHANCE The 2PN rate, blastocyst formation rate, and viable blastocyst formation rate of the E-RICSI group were significantly lower compared to the conventional ICSI group (2PN rate: P < 0.001; blastocyst formation rate: P < 0.001; viable blastocyst formation rate: P = 0.004), and the multi-PN rate in the E-RICSI group was significantly higher than the conventional ICSI group (P < 0.001). However, the number of 2PN embryos, normal cleavage embryo rate, Day 3 high-quality cleavage embryo rate, and high-quality blastocyst rate were similar between groups. When considering the IVF embryos and E-RCSI embryos in the E-RICSI group independently, the 2PN rate of the conventional ICSI group was significantly lower than E-RICSI subgroup but higher than the IVF subgroup, whereas the blastocyst formation rate and viable blastocyst formation rate were higher than E-RICSI embryos but comparable to IVF embryos. As for the clinical and neonatal outcomes, the implantation rate of the E-RICSI subgroup was significantly lower than the IVF subgroup but comparable to the conventional ICSI group, while the low birthweight (LBW) rate was significantly lower compared with the conventional ICSI group but similar with the IVF subgroup. No other differences were observed among the three groups for cumulative clinical pregnancy rate, cumulative live birth rate, and the pregnancy outcomes per transfer including clinical pregnancy, ectopic pregnancy, miscarriage, and live birth, either in fresh or frozen embryo transfer cycles. Furthermore, neonatal outcomes, including cesarean section, sex ratio, LBW, preterm birth, and macrosomia, were similar among groups. LIMITATIONS REASONS FOR CAUTION This study is limited by the retrospective design, limited sample size, and short follow-up period. However, our study underlies the need for large-scale, multi-center randomized controlled trials with long-term follow-up. WIDER IMPLICATIONS OF THE FINDINGS Short-term insemination (3 h) combined with E-RICSI may be a safe and effective method to prevent the occurrence of total fertilization failure, and patients with normal or borderline sperm could be encouraged to try IVF first. STUDY FUNDING/COMPETING INTERESTS This study was supported by grants from the National Key & Development Program of China (No. 2021YFC2700603) and the National Natural Science Foundation of China (No. 81801443). The authors declare no conflicts of interest. TRIAL REGISTRATION NUMBER N/A.

Abstract
Purpose To evaluate the efficacy and safety of short-term insemination and early-rescue intracytoplasmic sperm injection (ICSI), an approach that rescued oocytes with unclear second polar body 6 h after initial insemination by ICSI (early R-ICSI) to avoid total or near-total fertilization failure in conventional in vitro fertilization (IVF). Methods We performed a retrospective study in 16,769 patients (short-term IVF, n = 12,094; ICSI, n = 3452; early R-ICSI, n = 1223) who received IVF/ICSI treatment in our hospital from January 2009 to October 2018. Fertilization and clinical outcomes were compared among those three groups. Results When considering the R-ICSI embryos in the early R-ICSI group independently, the rates of fertilization and day-3 cleaved embryos in 2PN oocytes were comparable, the rates of fertilization (2PN) and high-quality embryos were lower, whereas the multi-PN fertilization rate (3.27%) was significantly higher than the ICSI group (1.26%). The difference of clinical pregnancy rate between the part of transferred R-ICSI embryos (40.81%) and the ICSI group (44.73%) remained nonsignificant. Furthermore, the rate of congenital birth defects in the early R-ICSI group (0.99%) was not significantly different from those in the short-term IVF (0.76%) and ICSI groups (1.07%). Conclusion Despite the multi-PN fertilization rate, our study highlights early R-ICSI as a safe and effective alternative in assisted reproduction to decrease complete IVF fertilization failure and reduce ICSI utilization. Additional large amount and long-term follow-up studies are needed to further validate the use of early R-ICSI.

Abstract
Background: Although rescue intracytoplasmic sperm injection (r-ICSI) is extensively used worldwide, the indication of r-ICSI and its optimal timing remains obscure. This study aimed to assess the outcomes of r-ICSI following in vitro fertilization in different timings when fertilization is confirmed. Methods: This study included 5,156 cycles (47,785 eggs). Fertilization was confirmed by polar body analysis after 4 and 6 hr of coincubation of the sperm and oocyte. Oocytes that underwent IVF were divided into two groups based on the time when a second polar body was detected in more than 30% of all oocytes (Four-hr group and six-hr group). If the second polar body was not detected or was present in less than 30% of all oocytes after six hr of coincubation, rescue-ICSI (r-ICSI) was performed for oocytes without a second polar body (r-ICSI group). Results: The fertilization rates of two pronuclear (2PN) oocytes in the three groups (Four-hr group, six-hr group, and r-ICSI group) were 70.7%, 51.3%, and 58.0%, respectively. The blastocyst formation rates were 62.8%, 53.4%, and 42.9%, respectively. Conclusion: Performing r-ICSI after six hr of coincubation can salvage cases with fertilization failure in IVF. The higher fertilization rate of r-ICSI indicates that all oocytes without signs of fertilization after six hr of coincubation should undergo r-ICSI.

Abstract
Purpose Early rescue intracytoplasmic sperm injection (ICSI) is often performed in cases in which not even a single oocyte has extruded a second polar body 6 h after insemination. We evaluated the usefulness of expanding the indications of early rescue ICSI to cases in which <80% of oocytes have extruded second polar bodies 6 h after insemination. Methods Early rescue ICSI was performed on oocytes that were denuded 2.5 h post‐insemination and whose extrusion of the second polar bodies had been examined 6 h post‐insemination with a PolScope. Results In vitro fertilization was performed on 24 496 oocytes of 4944 cycles, and 1438 cycles had <80% rate of the second polar body extrusion. Rescue ICSI was performed on 3933 oocytes. Three pronuclei (3PN) incidence of rescue ICSI was 3.0% in oocytes with ≥50% rate of the second polar body extrusion. With respect to the second polar body extrusion rate, no differences were observed in normal fertilization, blastocyst development, implantation, miscarriage, or live birth rates for rescue ICSI. Conclusion By expanding the indications of early rescue ICSI using the PolScope to cases in which <80% of oocytes have extruded the second polar bodies, many fertilized oocytes can be obtained without considerably increasing the 3PN rate.

Abstract
We investigated the feasibility of agarose-gel microcapsules to cryopreserve extremely small numbers of sperm for assisted reproductive technology. Semen samples were collected from 16 patients attending the center for reproductive medicine male infertility clinic at a university hospital. We used agarose microcapsules to cryopreserve extremely small numbers of sperm from 16 patients with male infertility (10 with sperm concentration ≥1 million/mL; 6 with sperm concentration <1 million/mL). Six spermatozoa were injected into agarose-gel microcapsules and cryopreserved in a liquid nitrogen tank for 7 days. The Crytop method was used for cryopreservation as a control. After thawing, spermatozoa were recovered. Sperm recovery rates, motility and viability, and recovery time were compared.The post-thawing recovery rate, motility rate, and viability rate were higher whereas the recovery time was shorter in samples preserved using the agarose-gel microcapsule method compared to samples preserved using the Cryotop method in both the group with sperm concentrations of 1 million/mL or above and the group with sperm concentrations of less than 1 million/mL. This study demonstrated that using the agarose-gel microcapsule method increased post-thawing sperm recovery rate, sperm motility rate, and sperm viability rate, and reduced sperm recovery time compared with the conventional Cryotop method when cryopreserving samples with low sperm count. Although requiring further study, the agarose-gel microcapsule method shows much promise as a new option for freezing sperm.

Blastocyst cryopreservation and cryopreservation-warming transfer is an effective embryo transfer strategy for day 1 rescue intracytoplasmic sperm injection cycles. Sci Rep 2021; 11:8260.

Abstract
This was a retrospective analysis of a total of 625 r-ICSI cycles using freeze-all-embryos and embryo transfers (ET) in subsequent cryopreservation-warming cycles to determine the effect of the ET method for day 1 rescue intracytoplasmic sperm injection cycles (r-ICSI). Two methods were used: in method 1, cleavage-stage embryos were frozen and were directly transferred in a subsequent cryopreservation-warming cycle (r-ICSI frozen cleavage), and 144 cleavage-stage ETs occurred. Similarly, in method 2, there were 188 blastocyst-stage ETs (r-ICSI frozen blast) performed. The live birth rate (LBR) for r-ICSI frozen blast was better than that for r-ICSI frozen cleavage in calculation of ET cycles (19.44% vs. 37.77%) and also remained better after the use of logistic regression analysis (OR = 2.721, 95% CI 1.604–4.616). Conservative cumulative LBR were compared between r-ICSI frozen cleavage and r-ICSI frozen blast with regard to oocyte retrieval cycles (17.39% vs. 15.30%). The same results were obtained for conservative cumulative LBR after logistic regression analysis (OR = 0.925, 95% CI 0.557–1.535). The results of this study confirmed that it was valuable to perform r-ICSI if using freeze-all-embryos. Further, r-ICSI embryos were cultured to blastocyst stage, cryopreserved, and used in subsequent cryopreservation-warming cycles, which was an effective embryo transfer strategy and obtained satisfactory results.

Abstract
OBJECTIVES We aimed to explore the effect of three pro-nuclei (3PN) incidence on laboratory and clinical outcomes after early rescue intracytoplasmic sperm injection (rescue-ICSI). METHODS This study included 509 early rescue-ICSI cycles from February 2014 to February 2019. The patients were divided into 3PN = 0% (394 cycles) and 3PN > 0% (115 cycles) group. Main outcomes compared were good quality embryo, available embryo, implantation (IR), clinical pregnancy (CPR), abortion (AR) and live birth rates (LBR). RESULTS There were no significant differences in the basal characteristics between two groups (p > .05). We observed that 3PN = 0% and 3PN > 0% groups had similar good quality embryo (47.02 versus 46.80%; p = .917) and available embryo (83.28 versus 81.37%; p = .247) rates. Our results showed that the IR (47.26 versus 51.05%; p = .357), CPR (61.17 versus 66.08%; p = .338) and LBR (52.80 versus 50.43%; p = .656) were comparable between 3PN = 0% and 3PN > 0% groups. The 3PN = 0% group showed significantly lower AR than that in the 3PN > 0% group (11.20 versus 21.05%; p = .029; OR 2.114; 95% CI 1.069-4.178). CONCLUSIONS 3PN incidence made negative effects on the clinical outcomes after early rescue-ICSI.

Abstract
Purpose Intracytoplasmic sperm injection (ICSI) is the most widely utilized assisted reproductive technique (ART) worldwide. In this feature, we review the early assisted fertilization attempts that eventually led to the development of ICSI, and discuss its current utilization in cases of male and non-male factor infertility. Methods We researched the literature related to the development, indications, and current use of ICSI, such as sperm structural abnormalities, male genetic indications, surgically retrieved sperm, high sperm chromatin fragmentation, oocyte dysmorphism, and preimplantation genetic testing (PGT). We also describe the potential future applications of ICSI. Results This review summarizes the early micromanipulation techniques that led to the inception of ICSI. We also explore its current indications, including non-male factor infertility, where its use is more controversial. Finally, we consider the benefits of future advancements in reproductive biology that may incorporate ICSI, such as in vitro spermatogenesis, neogametogenesis, and heritable genome editing. Conclusion The versatility, consistency, and reliability of ICSI have made it the most prevalently utilized ART procedure worldwide.

Abstract
Background Early rescue intracytoplasmic sperm injection (ICSI) has been used in clinic as appropriate currently. While the outcomes of children born after this method were not well assessed. The purpose of this study was to evaluate the effect of early rescue ICSI on women with primary infertility. Methods Fresh embryo transfer cycles after rescue (n = 214) and conventional (n = 546) ICSI were retrospectively evaluated from women with primary infertility who underwent their first assisted reproductive technology cycles at our center in 2012–2017. The conventional ICSI group was subdivided into ICSI-1 (semen suitable for in vitro fertilization, IVF) and ICSI-2 (poor semen quality) to minimize bias from differences in semen quality. Pregnancy, delivery and neonatal outcomes were compared between groups. Results There was a higher rate of polyspermy and a lower rate of top-quality embryos (TQE) on day 3 for oocytes subject to rescue ICSI compared with conventional ICSI. This reduced the total number of TQE and the number of TQE transferred in the rescue ICSI group. There was no significant difference between groups in clinical pregnancy, ongoing pregnancy, early miscarriage and live birth. For pregnant women, gestational age, route of delivery, risk of preterm birth and gestational diabetes mellitus were also comparable. Neonatal outcomes including sex ratio, birth weight, neonatal intensive care unit admission and birth defects were also similar after rescue and conventional ICSI. Moreover, no differences were observed with the different ICSI subgroups. Conclusions For women with primary infertility who have a high risk of IVF fertilization failure (FF), rescue ICSI provides a safe and efficient alternative to minimize FF after initial IVF, but results in fewer TQE on day 3.

Abstract
PURPOSE To report a live birth after transfer of a vitrified-warmed blastocyst produced by assisted sperm fusion insemination (ASFI). METHODS Oocyte retrieval and in vitro fertilization (IVF) were performed on a 37-year-old woman. Six hours after IVF, an oocyte exhibited a single polar body and so was defined as an unfertilized oocyte. A motile sperm was collected from the zona pellucida of the unfertilized oocyte by an injection needle. The motile sperm was pressed onto the membrane of the unfertilized oocyte. RESULTS Two oocytes were matured and subjected to IVF. One of the 2 oocytes exhibited only one polar body and was defined as an unfertilized oocyte at 6 h after IVF; this oocyte then was subjected to ASFI. Two pronuclei were observed on the next day and cultured to the blastocyst stage. This embryo achieved blastocyst status and was vitrified on day 5. The resulting vitrified-warmed blastocyst was transferred, resulting in pregnancy and subsequent delivery of a healthy boy. CONCLUSION This report describes the first case of a successful birth following transfer of a vitrified-warmed blastocyst produced by ASFI.

Abstract
This study aimed to determine whether fertilization can be obtained by assisted fusion of oocyte and sperm without breaking the oocyte membrane. A total of 79 infertile couples, each with at least one unfertilized oocyte after in vitro fertilization (IVF), were recruited. Sperm collected from the zona pellucida (ZP) were pressed onto the membrane of unfertilized oocytes at either 6 h or 24 h after IVF, a procedure that we designated as assisted sperm fusion insemination (ASFI). The results of ASFI were compared with those obtained in a previous trial on oocytes in which rescue intracytoplasmic sperm injection (ICSI) was performed at 6 h after IVF. Acrosome reaction (AR) rate of sperm bound to ZP, fertilization rate, degeneration rate, and blastocyst formation rate were evaluated. The AR rate of sperm collected from the ZP was significantly higher than that of the motile sperm recovered from around the oocytes but not bound to the ZP after IVF (98.0% vs. 28.6%). ASFI which was performed at 6 h after IVF yielded a mean fertilization rate of 73.4% (58/79), a degeneration rate of 0% (0/79) and a blastocyst formation rate of 60.8% (31/51). Rescue ICSI which was performed at 6 h after IVF yielded a mean fertilization rate of 70.0% (70/100), a degeneration rate of 4% (4/100) and a blastocyst formation rate of 42.4% (25/59). Binding of sperm to the ZP typically results in AR. ASFI with acrosome-reacted sperm collected from the ZP yielded the fertilization rates similar to those obtained with rescue ICSI.

Abstract
OBJECTIVE The objective of this retrospective study was to evaluate clinical outcomes of early cumulus cells removal and early rescue intracytoplasmic sperm injection (ICSI) in high-risk patients of fertilization failure during human in vitro fertilization (IVF). METHODS A total of 5,518 patients were enrolled between January 2014 to December 2016. Of which 505 couples performed short insemination with >30% fertilization rate were included in short-term IVF group, 102 patients detected total fertilization failure (TFF) were treated with early rescue ICSI (R-ICSI group), and 4911 couples underwent conventional IVF with overnight co-incubation of gametes (traditional IVF group). The clinical outcomes were analyzed among the three groups. RESULTS The embryo implantation rates (40.34%, 39.78% and 42.42% for traditional, short-term IVF and R-ICSI groups, respectively) were comparable in the three groups. The clinical pregnancy rates among traditional IVF group, short-term IVF group and R-ICSI group were 57.95%, 57.03% and 60.78%, respectively, and the difference among three groups didn't reach significance. CONCLUSION The present study indicated that short insemination had no detrimental effects on clinical outcomes in human IVF and could prevent the occurrence of TFF combined with early rescue ICSI for high-risk patients of fertilization failure, which attained acceptable pregnancy outcomes.

Abstract
Changes in oocyte quality can have great impact on the developmental potential of early embryos. Here we test whether nuclear genome transfer from a developmentally incompetent to a developmentally competent oocyte can restore developmental potential. Using in vitro oocyte aging as a model system we performed nuclear transfer in mouse oocytes at metaphase II or at the first interphase, and observed that development to the blastocyst stage and to term was as efficient as in control embryos. The increased developmental potential is explained primarily by correction of abnormal cytokinesis at anaphase of meiosis and mitosis, by a reduction in chromosome segregation errors, and by normalization of the localization of chromosome passenger complex components survivin and cyclin B1. These observations demonstrate that developmental decline is primarily due to abnormal function of cytoplasmic factors involved in cytokinesis, while the genome remains developmentally fully competent. In vitro aging as a model of oocyte fragmentation and poor developmental potential Nuclear transfer restores normal cytokinesis of in vitro aged mouse oocytes Nuclear transfer restores development to term of in vitro aged oocytes Developmental potential is primarily limited by the cytoplasm, not the nucleus

Abstract
To explore the need for rescue intracytoplasmic sperm injection (ICSI) in cases of partial fertilisation failure during a conventional in vitro fertilisation cycle, rescue ICSI was performed for cycles with a fertilisation rate of <50%. The data were divided into three groups based on the fertilisation rate: group 1 (0%), group 2 (<25%) and group 3 (>25%). The impact of rescue ICSI on each group was then analysed in terms of ovum fertilisation, embryo development, embryo utilisation and selection of embryos for transfer. Rescue ICSI was performed on 1831 unfertilised oocytes from 313 cycles. The fertilisation rates for group 1, group 2 and group 3 were 74.66, 68.35 and 65.46%, and the rate of polyploidy in the three groups was 8.55, 11.33, and 14.47%. The percentage of embryos that can be transferred from rescue ICSI for group 2 was 38.33%, and this value was higher than those of the other two groups. It is concluded that rescue ICSI is not recommended for patients with an IVF rate of >25% as the procedure is associated with a greater risk and low returns. However, it is feasible to perform rescue ICSI for patients with IVF rates of <25%.

Abstract
PURPOSE In order to identify the real contribution of early fertilization check (EFC) for reproductive outcome, we compared the developmental potential of embryos derived from intracytoplasmic sperm injection (ICSI) after EFS with those from conventional insemination in sibling oocytes. METHODS Between April 2009 and April 2012, a total of 3249 oocytes in 386 patients were recruited following conventional insemination. Oocytes showing a second polar body (2ndPB) after an EFC were considered to be fertilized oocytes (IVF group), but, oocytes not showing a 2ndPB after EFC were placed into the ICSI group. The incidence of morphologically good embryos (MGE) on day 3, the blastocyst formation (BL), and the development of full blastocysts (full-BL) on day 5 were compared between the two groups. The clinical pregnancy rate was compared between the cycles with only conventional insemination or ICSI after EFC of the embryos being transferred. RESULTS The fertilization rates in both the IVF and the ICSI groups were 48.1 and 73.9 %, respectively. The percentage of MGE in the ICSI group (40.8 %) was significantly lower than that in the IVF group (56.1 %, p < 0.01). The percentages of BL and full-BL in the ICSI group were significantly lower than those in the IVF group. The pregnancy rates were similar in both the groups. CONCLUSIONS Checking fertilization earlier than the usual period contributed to an avoidance of lower fertilization. Moreover, the embryos derived from ICSI after EFC possessed a normal developmental potential.

Abstract
This article aims to report successful live births after transfer of fresh blastocyst or vitrified/warmed blastocyst derived from intracytoplasmic sperm injection (ICSI) on day-1 of unfertilized mature eggs (so-called “rescue ICSI”) with spindle examination using polarized light microscopy. Two couples who had rescue ICSI performed achieved a positive pregnancy result after the transfer of a fresh or vitrified blastocyst. The two pregnancies led to the live births of a healthy baby boy of 2.72 kg and baby girl of 3.4 kg, respectively.

PURPOSE To evaluate the impact of early rescue ICSI on neonatal outcome. METHODS This retrospective study compared the neonatal outcome of early rescue ICSI and ICSI with ejaculated sperm, including 233 children who were conceived after early rescue ICSI and a control group of 906 children who were conceived after ICSI with ejaculated sperm, and all of the children had a gestational age of 20 weeks or more. The numbers of live and stillbirths, perinatal deaths, prematurity, birthweights and birth defects of the children were compared. RESULTS Children in the early rescue ICSI group showed no increased risk of stillbirths, perinatal death or birth defects. Those children also did not differ from those of the ICSI with ejaculated sperm group in gender rate, birthweight, gestational age or prematurity. CONCLUSIONS Early rescue ICSI did not increase the adverse effect on the neonatal outcome when compared to that of ICSI with ejaculated sperm.

Abstract
OBJECTIVE To assess the feasibility, efficacy, and safety of rescue intracytoplasmic sperm injection (ICSI) in cases of fertilization failure, using a scientific literature search. DESIGN Systematic review. SETTING Centers for reproductive care. PATIENT(S) Infertility patients with total or partial fertilization failure during an IVF cycle. INTERVENTION(S) An electronic literature search was performed in PubMed from 1992 through May 2013. The search was then expanded by using listed references from selected articles. MAIN OUTCOME MEASURE(S) Pregnancy rate. The secondary outcome measures were fertilization rate, normal fertilization rate, cleavage rate, birth rate, and malformation rate. RESULT(S) Thirty-eight studies including 1,863 patients were included. The pooled pregnancy rate was 14.4%; 194 babies were delivered. CONCLUSION(S) Rescue ICSI can result in the delivery of a healthy newborn, although the pregnancy rates are low. The clinical evidence did not indicate an elevated rate of malformations, although the data are limited and incomplete.

Abstract
Failed fertilization after conventional IVF is one of the most frustrating experiences in assisted reproductive technology. "Late" rescue ICSI may be not an optimal strategy for treating unfertilized oocytes. Short co-incubation of gametes combined with early rescue ICSI has some advantages for complete fertilization failure after IVF. We evaluate the strategy and the optimal time for early rescue ICSI. A total of 180 patients underwent short co-incubation of gametes combined with early rescue ICSI treatment for complete fertilization failure after IVF (study group). A total of 494 ICSI patients with male factor infertility served as a control group. Clinical pregnancy rate, implantation rate, and live birth rate in the two groups were compared. The study group was divided into three different rescue time intervals (<6 h, 6-8 h, and >8 h). Clinical pregnancy rate, implantation rate, and live birth rate were comparable between the study group and the control group. There was a negative correlation between clinical outcomes and rescue time interval.

Abstract
In a conventional IVF cycle unexpected complete fertilization failure may occur in 10-25% of infertile women. To overcome this barrier of fertilization failure, some investigators have suggested intracytoplasmic sperm injection (ICSI) on day 1 of an unfertilized mature oocyte, the so called “rescue ICSI”. We report a case of fertilization failure followed by rescue ICSI resulting in a live birth. Although the success of rescue ICSI is still questionable, this procedure is worth an attempt in order to give the best chance to the couple in that cycle.

We included ICSI cycles with the following parameters: rank 1 or 2, female age <36 years, male factor infertility, long protocol using GnRH agonist and rFSH for ovarian stimulation, and use of freshly ejaculated sperm (n = 110). Several ICSI parameters were analyzed according to the time between oocyte retrieval and denudation (T1) and the time between denudation and ICSI (T2) using a statistical logistic regression analysis. Results. Neither T1 nor T2 had a significant influence on the Metaphase II (MII) rate but the fertilisation rate (FR) showed a significant improvement when T1 was longer (optimal results at T1 = 3
hours) while FR significantly decreased with the increase of T2. Optimal implantation (IR) and pregnancy (PR) rates were obtained when T1 was around 2 hours.
Conclusion. Incubation of oocytes around 2 hours between retrieval and denudation may not increase MII rate but appears to lead to the optimal combination of FR and IR.

Ming L, Liu P, Qiao J, Lian Y, Zheng X, Ren X, Huang J, Wu Y. Synchronization between embryo development and endometrium is a contributing factor for rescue ICSI outcome. Reprod Biomed Online 2012; 24:527-31. [PMID: 22480904 DOI: 10.1016/j.rbmo.2012.02.001] [Citation(s) in RCA: 35] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2012] [Revised: 01/31/2012] [Accepted: 02/01/2012] [Indexed: 11/18/2022]
Abstract
Recent evidence shows that the outcome of rescue intracytoplasmic sperm injection (ICSI) is unsatisfactory on account of a poor clinical pregnancy rate. These outcomes may be due to either the in-vitro ageing of cultured oocytes before ICSI or the asynchrony between the embryo developmental stage and the endometrial secretory pattern. To address the latter issue, this study performed a retrospective analysis of 534 fresh cycles after rescue ICSI and 64 frozen-thawed cycles in subsequent treatment. Rescue ICSI cycles were divided into three groups: group I included 469 fresh embryo-transfer (FET) cycles; group II included 74 FET cycles in which supernumerary good-quality embryos were also cryopreserved; and group III included 64 frozen-thawed transfer cycles. Group III was considered to have achieved better synchronization than group II. As a result, significantly higher clinical pregnancy (29.69%, 19/64 versus 10.81%, 8/74) and implantation (13.33%, 22/165 versus 5.13%, 8/156) rates were achieved in group III compared with group II (both P<0.05). Therefore, synchronization of embryo development with the endometrium is considered a contributing factor for rescue ICSI outcome. It is recommended that embryos derived from rescue ICSI cycles should be cryopreserved and subsequently used in frozen-thawed cycles. Intracytoplasmic sperm injection (ICSI) of unfertilized 1-day-old oocytes, called rescue ICSI, has frequently been performed in some infertility centres, when fertilization failure sometimes occurs in conventional IVF cycles. Recent studies showed that the outcome of rescue ICSI was unsatisfactory due to poor clinical pregnancy rates. One reason could be asynchrony between the embryo developmental stage and the endometrial secretory pattern. To address this issue, we performed a retrospective analysis of 534 fresh cycles after rescue ICSI (from January 2006 to January 2011) and 64 frozen-thawed transfer cycles in subsequent treatment (from January 2006 to May 2011) in our infertility centre. In this study, rescue ICSI cycles were divided into three groups. As there was no significant difference in women's age (31.22 ± 3.38 versus 31.11 ± 3.27 years) between groups II and III, we principally compared these two groups. Group II included 74 fresh embryo transfer cycles, in which supernumerary good-quality embryos were cryopreserved, and group III included 64 frozen-thawed transfer cycles. Group III was considered to have better synchronization than group II. As a result, significantly higher clinical pregnancy (29.69% versus 10.81%) and implantation (13.33% versus 5.13%) rates were achieved in group III compared with group II. Therefore, endometrial synchronization is considered a contributing factor for rescue ICSI outcome and embryos derived from rescue ICSI cycles should be cryopreserved and subsequently used in frozen-thawed cycles.

Abstract
OBJECTIVE To identify clinical and embryological factors that may predict success in rescue intracytoplasmic sperm injection (ICSI) cycles (after total fertilization failure has occurred) and to evaluate the cost effectiveness of rescue ICSI strategy. Additionally, follow-up of 20 rescue ICSI pregnancies is reported. DESIGN Retrospective analysis of total fertilization failure cycles. SETTING University-based tertiary medical center. MATERIAL AND METHODS In total, 92 patients who had undergone conventional in-vitro fertilization (IVF) cycles with total fertilization failure were included. The patients were divided into two subgroups: those who conceived through rescue ICSI and those who did not. RESULTS The pregnant members of the rescue ICSI subgroup were found to be significantly younger (32.9 ± 4.2 vs. 36.3 ± 4.5, respectively, p = 0.0035,) and to have better-quality embryos than those who did not conceive (cumulative embryo score: 38.3 ± 20.4 vs. 29.3 ± 14.7, p = 0.025). Cost effectiveness analysis showed 25% reduction in the cost per live birth when rescue ICSI is compared to cycle cancellation approach. The pregnancies follow-up did not show adverse perinatal outcome. CONCLUSIONS Rescue ICSI is an option for salvaging IVF cycles complicated by total fertilization failure. Success in rescue ICSI was found to be associated with younger age and higher quality of embryos. Furthermore, the cost effectiveness of rescue ICSI in terms of total fertilization failure was found to be worthwhile.

Abstract
PURPOSE To investigate the effects of cumulus cells removal after 6 h co-incubation of gametes on the fertilization, polyspermy, multinucleation and clinical pregnancy rates in human IVF. METHODS A total of 1,200 IVF-ET cycles undergoing 6 h co-incubation of gametes in 2009 were included in this study. Inclusion criteria were: female age <38 years, first IVF treatment, with bi-ovary and normal ovarian response, e.g., 4 ~ 20 oocytes could be obtained. A 6 h period of co-incubation was applied in all IVF cycles. According to the history of infertility, cumulus cells were mechanically removed either 6 h post-insemination or 20 h post-insemination. For couples with primary infertility, or unexplained infertility, or mild oligospermia or asthenospermia, the cumulus cells were removed at 6 h of insemination for the polar body observation (6 h group, n = 565). Of these, 80 cycles received early rescue ICSI due to fertilization failure or low fertilization rate at 6 h of insemination. For couples with secondary infertility and normal semen analysis, the cumulus cells were removed at 20 h of insemination as routine (20 h group, n = 635). Of these, three cycles received late rescue ICSI due to fertilization failure at 20 h of insemination. Normal fertilization, polyspermy (≥3PN), multinucleation and clinical pregnancy rates were compared between the two groups (rescue ICSI cycles were not included in the comparison in both groups). RESULTS Significant difference (P < 0.05) was observed between the groups regarding polyspermy rates (7.48% in 6 h group and 9.22% in 20 h group). No difference was observed between the groups regarding normal fertilization rates (2PN rate) (64.89% in 6 h group and 65.74% in 20 h group). No difference was observed between the groups regarding multinucleation and clinical pregnancy rates (11.01% and 65.15% in 6 h group, 10.75% and 66.93% in 20 h group, respectively). The clinical pregnancy rate was 51.43% in cycles receiving early rescue ICSI, while no clinical pregnancy was obtained in cycles receiving late rescue ICSI. CONCLUSION The present results indicate that cumulus cells removal at 6 h of insemination is a relatively safe operation, which yielded comparable normal fertilization rate, multinucleation and clinical pregnancy rates compared with 20 h group. This protocol may be beneficial for early obsevation of fertilization failure and make early rescue ICSI possible.

Abstract
Postovulatory mammalian oocytes age significantly in culture. B6D2F1 or ICR strain mouse oocytes were collected 16 h after hCG injection and then cultured for up to 40 h post hCG at 37 °C under 5% CO(2) in air. After intracytoplasmic sperm injection (ICSI), B6D2F1 and ICR oocytes lost full-term developmental potential by 30 h and 26 h after hCG administration, respectively. However, using supplementation with 10 mM caffeine or 1-5 μM of MG132, we could obtain live offspring from oocytes at 34 h (BDF1, 5%-21%) or 28 h (ICR, 5%-18%), whereas none were obtained from untreated aged oocytes. Caffeine maintained normal meiotic spindle morphology, whereas MG132 maintained maturation-promoting factor activity. These treatments did not affect the potential of fresh oocytes for fertilization and subsequent development. Thus, it should be safe to use these chemicals in routine in vitro fertilization and offspring could be generated by ICSI of aged fertilization failed oocytes.

Abstract
It has now been 13 years since the first cloned mammal Dolly the sheep was generated from somatic cells using nuclear transfer (SCNT). Since then, this technique has been considered an important tool not only for animal reproduction but also for regenerative medicine. However, the success rate is still very low and the mechanisms involved in genomic reprogramming are not yet clear. Moreover, the NT technique requires donated fresh oocyte, which raises ethical problems for production of human cloned embryo. For this reason, the use of induced pluripotent stem cells for genomic reprogramming and for regenerative medicine is currently a hot topic in this field. However, we believe that the NT approach remains the only valid way for the study of reproduction and basic biology. For example, only the NT approach can reveal dynamic and global modifications in the epigenome without using genetic modification, and it can generate offspring from a single cell or even a frozen dead body. Thanks to much hard work by many groups, cloning success rates are increasing slightly year by year, and NT cloning is now becoming a more applicable method. This review describes how to improve the efficiency of cloning, the establishment of clone-derived embryonic stem cells and further applications.

Abstract
Mammalian fertilization, whether it takes place within the female reproductive tract or within a laboratory dish, is comprised of many processes which must follow a specific sequence. The spermatozoon must bind to and pass through the zona pellucida, fuse with the oolemma and become incorporated into the cytoplasm of the oocyte. Fusion of the two gametes triggers oocyte activation, resulting in exocytosis of the cortical granules and completion of the second meiotic division of the oocyte. A block in one or more of these processes, due either to abnormalities in the spermatozoon or oocyte, may result in fertilization failure.

Abstract
Cloning methods in mice are now well described and are becoming routine. However, the frequency at which cloned mice are produced remains below 5%, irrespective of the nucleus donor species or cell type. Only a few laboratories have made clones from adult mouse somatic cells and most strains have never produced cloned mice. On the other hand, nuclear transfer can be used to generate human embryonic stem (ntES) cell lines from a patient's own somatic cells. It has been shown that such cells can be generated relatively easily from a variety of mouse genotypes and cell types of both sexes, even though it may be more difficult to generate clones directly. This technique could be used in regenerative medicine and, in theory, in infertility clinics to treat completely infertile individuals. However, these results suggest that the reprogramming integrity of each cloned embryo differs: some cloned embryos can be converted to ntES cells, but these embryos cannot achieve full term development. This review outlines the nature of genomic reprogramming potential and its application, and suggests new approaches to avoid the ethical problems of creating embryos by nuclear transfer.

OBJECTIVE To evaluate the results of a novel protocol that allows to rescue IVF unfertilized oocytes by intracytoplasmic sperm injection (ICSI). DESIGN Prospective clinical trial. SETTING Private reproductive medical center. PATIENT(S) Thirty patients undergoing IVF. INTERVENTION(S) Controlled ovarian stimulation (COS), conventional IVF, rescue ICSI, embryo culture, and embryo transfer. MAIN OUTCOME MEASURE(S) Identification of unfertilized IVF oocytes 6 hours after insemination and fertilization, and developmental rates of those oocytes after rescue microinjection, as well implantation and pregnancy rates (PR). RESULT(S) All oocytes (392) from 30 patients were inseminated with standard IVF 3 hours after ovum pick-up. Polar body (PB) status was checked at decumulation and rechecked 3 hours later. Eighty-two oocytes were fertilized after IVF alone and 184 nonactivated oocytes (failed fertilization) were rescue microinjected and 166 of them fertilized (20 patients). Cleavage stage on day 2 was significantly more advanced and embryo grade was higher after standard IVF fertilization than after rescue ICSI. Eight of the 30 embryos transferred were implanted in the IVF-only patients (27%) and 8 of 68 embryos in the rescue ICSI patients (12%). CONCLUSION(S) Rescue ICSI of unfertilized IVF oocytes 6 hours after insemination (9 hours after egg retrieval) can provide normal fertilization, embryo development, and pregnancy; however, corresponding outcome parameters tend to be impaired in comparison to the standard IVF fertilization results.

Abstract
BACKGROUND Intracytoplasmic sperm injection (ICSI) has risen to the forefront of reproductive technology. In the present study, the location of the sperm injection was noted, and a prospective study was conducted to evaluate the effect of the sperm retention site on cleavage rates and embryo quality after ICSI. METHODS This study involved 336 ICSI patients (age 27-44; average 37.4) where 1545 oocytes were observed. An oocyte was divided into nine sites and the sperm retention site was observed microscopically after injection. The polar body was placed at either the twelve or six o'clock position. The injection pipette was introduced at the three o'clock position and oolemma rupture was ascertained by mild suction. The main outcome measures were the relationship of sperm remaining in position in the oocyte to fertilization rate and embryo quality. RESULTS When the injection pipette was introduced at the three o'clock position, about 80% of the sperm remained in the center or left of center. The fertilization rate was significantly lower (p < 0.05) when the sperm remained near the site of introduction. Embryo quality was not significantly affected by the sperm retention site. CONCLUSIONS About 12-14% of the spermatozoa remained near the introducing position, and in these cases the fertilization rate was low. However, once fertilization occurred, the sperm retention site had minimal impact on embryo quality. Injecting sperm near the spindle site may improve embryo quality.

Abstract
PURPOSE To study if second day intracytoplasmic sperm injection (ICSI) results in chromosomal abnormalities in the embryos. METHODS Rescue ICSI was performed on 14 metaphase II (MII) oocytes after unsuccessful conventional IVF, four were fertilized. Fluorescent in situ hybridization (FISH) was performed on these four embryos and was informative for three. RESULTS There were two tetraploid embryos, one mosaic embryo with trisomy 21, tetrasomy 18, and tetrasomy for sex chromosomes in one cell and trisomy 22 in another cell. CONCLUSIONS We discourage the use of second day ICSI due to the observed increase in chromosomal abnormalities in these embryos.

Abstract
To investigate the biological significance of a longevity mutation found in daf-2 of Caenorhabditis elegans, we generated a homologous murine model by replacing Pro-1195 of insulin receptors with Leu using a targeted knock-in strategy. Homozygous mice died in the neonatal stage from diabetic ketoacidosis, whereas heterozygous mice showed the suppressed kinase activity of the insulin receptor but grew normally without spontaneously developing diabetes during adulthood. We examined heterozygous insulin receptor mutant mice for longevity phenotypes. Under 80% oxygen, mutant female mice survived 33.3% longer than wild-type female mice, whereas mutant male mice survived 18.2% longer than wild-type male mice. These results suggested that mutant mice acquired more resistance to oxidative stress, but the benefit of the longevity mutation was more pronounced in females than males. Manganese superoxide dismutase activity in mutant mice was significantly upregulated, suggesting that the suppressed insulin signaling leads to an enhanced antioxidant defense. To analyze the molecular basis of the gender difference, we administered estrogen to mutant mice. It was found that the survival of mice under 80% oxygen was extended when they were administered estradiol. In contrast, mutant and wild-type female mice showed shortened survivals when their ovaries were removed. The influence of estrogen is remarkable in mutant mice compared with wild-type mice, suggesting that estrogen modulates insulin signaling in mutant mice. Furthermore, we showed additional extension of survival under oxidative conditions when their diet was restricted. Collectively, we show that three distinct signals; insulin, estrogen, and dietary signals work in independent and cooperative ways to enhance the resistance to oxidative stress in mice.

Abstract
Fertilization rates increased continuously with the time elapsed after administration of hCG, reaching a peak of 84% when intracytoplasmic sperm injection (ICSI) was performed >41 hours after hCG administration. However, the highest implantation rate, 24%, was achieved when ICSI was performed 37-41 hours after hCG administration.

Abstract
OBJECTIVE To report the birth and normal pediatric follow-up of the first baby born after transfer of embryos derived from cryopreserved rescue intracytoplasmic sperm injection (ICSI). DESIGN Case report. SETTING Academic fertility unit. PATIENT(S) A 36-year-old woman with unexplained infertility. INTERVENTION(S) Reinsemination by ICSI ("rescue" ICSI) followed by cryopreservation at the pronuclear stage was performed after partial fertilization failure. MAIN OUTCOME MEASURE(S) Pregnancy, birth, and 1-year follow-up of the baby born after the transfer of the cryopreserved rescue ICSI embryos. RESULT(S) AND CONCLUSION(S) Zygotes obtained after rescue ICSI were able to tolerate the process of cryopreservation and resulted in a viable pregnancy and delivery.

Abstract
This case report describes a successful full-term pregnancy and birth after the transfer of rescue intracytoplasmic sperm injection (ICSI) embryos derived from 1-day-old oocytes. A total of eight oocytes were retrieved and inseminated 3 h after collection. No oocytes were fertilized 16-18 h after insemination. A rescue ICSI was performed on the four metaphase II stage oocytes. At the regular time (16 h after ICSI) of examination for fertilization, there were no distinct two pronuclei (2PN) in the cytoplasm of any oocytes, but the culture of these oocytes led to the development of four two-cell stage embryos 26 h after ICSI. Further culture of these four embryos showed development to a four-cell stage the following day. The transfer of three embryos resulted in a full-term pregnancy with the delivery of a pair of healthy twins. This result suggests that the observation of 2PN at the normal time of fertilization assessment may not appear to be an absolute indicator of fertilization in the case of rescue ICSI.

Abstract
The oxygen affinity of hemoglobin is critical for gas exchange in the lung and O(2) delivery in peripheral tissues. In the present study, we generated model mice that carry low affinity hemoglobin with the Titusville mutation in the alpha-globin gene or Presbyterian mutation in the beta-globin gene. The mutant mice showed increased O(2) consumption and CO(2) production in tissue metabolism, suggesting enhanced O(2) delivery by mutant Hbs. The histology of muscle showed a phenotypical conversion from a fast glycolytic to fast oxidative type. Surprisingly, mutant mice spontaneously ran twice as far as controls despite mild anemia. The oxygen affinity of hemoglobin may control the basal level of erythropoiesis, tissue O(2) consumption, physical activity, and behavior in mice.
