Impact of Transitory Hyperprolactinemia on Clinical Outcome of In Vitro Fertilization and Embryo Transfer This study aimed to evaluate the impact of serum prolactin concentration at the day of human chorionic gonadotropin (HCG) administration on the clinical outcome of in vitro fertilization and embryo transfer (IVF-ET). A total of 184 patients receiving the IVF-ET/ICSI-ET from October 2005 to March 2008 were retrospectively analyzed. Subjects were divided into four groups according to the serum prolactin concentration [<30 ng/mL (A), 30-60 ng/mL (B), 60-90 ng/mL (C), ≥90 ng/mL (D)] on the day of HCG administration during controlled ovarian stimulation (COS). In the Groups A, B, C and D, the implantation rate was 11.76%, 19.71%, 12.72% and 2.22%, respectively, and the pregnancy rate (PR) was 25.00%, 42.70%, 27.30% and 5.88%, respectively. The implantation rate and PR in the Group D were markedly lower than those in the remaining groups (P=0.011 and 0.009). During the COS, the serum prolactin concentration was dramatically elevated when compared with the baseline level leading to transient hyperprolactinemia. In addition, the implantation rate and pregnancy rate were significantly markedly decreased when the serum prolactin concentration was remarkably increased (≥90 ng/mL). To improve the clinical pregnancy rate of IVF-ET, close monitoring and appropriate intervention are needed for patients with an abnormal prolactin level during the COS.

Abstract Background Total fertilization failure represents a particularly frustrating condition for couples undergoing in vitro fertilization. With the aim of reducing the occurrence of total fertilization failure, intracytoplasmic sperm injection (ICSI) has become the first choice over conventional in vitro fertilization (IVF) procedures although evidence of improved results is still debated and its use in couples without male factor infertility is not recommended. Among the strategies potentially useful to promote the use of conventional IVF, we herein call attention to the late rescue ICSI, which consists in performing ICSI after 18–24 h from conventional insemination on oocytes that show no signs of fertilization. This treatment has however been reported to be associated with a low success rate until recent observations that embryos derived from late rescue ICSI may be transferred after cryopreservation in a frozen-thawed cycle with improved results. The aim of the present study was to assess whether frozen embryos deriving from rescue ICSI performed about 24 h after conventional IVF may represent a valuable option for couples experiencing fertilization failure. Methods A systematic review on the efficacy of late rescue ICSI was performed consulting PUBMED and EMBASE. Results Including twenty-two original studies, we showed that clinical pregnancy rate per embryo transfer and implantation rate obtainable with fresh embryo transfers after rescue ICSI are not satisfactory being equal to 10 and 5%, respectively. The transfer of cryopreserved rescue ICSI embryos seems to offer a substantial improvement of success rates, with pregnancy rate per embryo transfer and implantation rate equal to 36 and 18%, respectively. Coupling rescue ICSI with frozen embryo transfer may ameliorate the clinical pregnancy rate for embryo transfer with an Odds Ratio = 4.7 (95% CI:2.6–8.6). Conclusion Results of the present review support the idea that r-ICSI coupled with frozen embryo transfer may overcome most of the technical and biological issues associated with fresh transfer after late r-ICSI, thus possibly representing an efficient procedure for couples experiencing fertilization failure following conventional IVF cycles.

Abstract Background: In this study, we compared the in vitro embryo development, embryo transfer outcome and the offspring outcome in the in vitro fertilization-embryo transfer (IVF-ET) between dry culture (DC) and humid culture (HC). Methods: Our study was divided into two parts. Firstly, we determined the fertilization rate, cleavage rate and high-quality embryo rate from 21 cycles in the DC group (N=262 oocytes) and HC group (N=263 oocytes). Secondly, we determined the embryo transfer outcome and the offspring outcome in DC group (N=184 cycles) and HC group (N=136 cycles). Results: Compared with the HC group, significant increase was observed in the high-quality embryo rate (66.1.2% vs. 55.3%, p=0.037) and implantation rate (49.8% vs. 40.6%, p=0.027) in the DC group. No statistical differences were observed in the pregnant outcome and birth defect of the offspring (p>0.05). Compared with HC, DC was associated with a higher high-quality embryo rate and a higher implantation rate after embryo transfer. Conclusions: No statistical differences were noticed in the offspring conditions between the two culture modes. Taken together, DC may serve as a promising method for IVF-ET.

Aim. To address the impact of noncavity-distorting intramural fibroids on the efficacy of in vitro fertilization-embryo transfer (IVF-ET) outcomes. Methods. The PubMed, Web of Science, Embase, Cochrane Library, and China National Knowledge Infrastructure were searched systematically. A meta-analysis was performed based on comparative or cohort studies that explored the impact of noncavity-distorting intramural fibroids on the efficacy of IVF-ET treatment. The IVE-ET outcomes of study group (women with noncavity-distorting intramural fibroids) and control group (women without fibroids) were compared, including live birth rate (LBR), clinical pregnancy rate (cPR), implantation rate (IR) , miscarriage rate (MR), and ectopic pregnancy rate (ePR). Results. A total of 28 studies involving 9189 IVF cycles were included. Our meta-analysis showed a significant reduction of LBR in the study group compared to control group (RR = 0.82, 95% CI: 0.73-0.92, and P = 0.005). In addition, it indicated that study group had a significant reduction in cPR (RR = 0.86, 95% CI: 0.80-0.93, P = 0.0001) and IR (RR = 0.90, 95% CI: 0813-1.00, P = 0.04) and have a significantly increase in MR (RR = 1.27, 95% CI: 1.08-1.50, and P = 0.004) compared with control group. Conclusions. The present evidence suggests that noncavity-distorting intramural fibroids would significantly reduce the IR, cRP, and LBR and significantly increase the MR after IVF treatment, but it would not significantly increase the ePR.

Day 5 Transfer

Abstract Background For women undergoing in vitro fertilization (IVF), the clinical benefit of embryo transfer at the blastocyst stage (Day 5) versus cleavage stage (Day 3) remains controversial. The purpose of this study is to compare the implantation rate, clinical pregnancy rate and odds of live birth of Day 3 and Day 5 embryo transfer, and more importantly, to address the issue that patients were chosen to receive either transfer protocol due to their underlying clinical characteristics, i.e., confounding by indication. Methods We conducted a retrospective cohort study of 9,090 IVF cycles collected by Lee Women’s Hospital in Taichung, Taiwan from 1998 to 2014. We utilized the method of propensity score matching to mimic a randomized controlled trial (RCT) where each patient with Day 5 transfer was matched by another patient with Day 3 transfer with respect to other clinical characteristics. Implantation rate, clinical pregnancy rate, and odds of live birth were compared for women underwent Day 5 transfer and Day 3 transfer to estimate the causal effects. We further investigated the causal effects in subgroups by stratifying age and anti-Mullerian hormone (AMH). Results Our analyses uncovered an evidence of a significant difference in implantation rate (p=0.04) favoring Day 5 transfer, and showed that Day 3 and Day 5 transfers made no difference in both odds of live birth (p=0.27) and clinical pregnancy rate (p=0.11). With the increase of gestational age, the trend toward non-significance of embryo transfer day in our result appeared to be consistent for subgroups stratified by age and AMH, while all analyses stratified by age and AMH were not statistically significant. Conclusions We conclude that for women without strong indications for Day 3 or Day 5 transfer, there is a small significant difference in implantation rate in favor of Day 5 transfer. However, the two protocols have indistinguishable outcomes on odds of live birth and clinical pregnancy rate.
