Impact of different embryo loading techniques on pregnancy rates in in vitro fertlizaton/embryo transfer cycles

Background: Embryo transfer (ET) technique is one of the important factors of in vitro fertlization success. Among the different steps in ET technique, less attention has been given to embryo loading (EL). The aim was to compare the impact of two different techniques of EL on pregnancy rate in IVF/ET cycles. Materials and Methods: In this retrospective study, 144 and 170 patients were placed in groups A and B, respectively. In Group A, the embryos were drawn directly into the ET catheter from culture microdrop under the oil. In Group B, the embryos were transferred from culture microdrop into G2 medium in center-well dish. Then, the embryos were drawn into the catheter and finally transferred into the uterus. Both groups were adjusted for other parameters based on the EL technique. The main outcome measure was pregnancy rate. Results: There were insignificant differences for etiology of infertility, source of sperm, type of stimulation protocol, percent of IVF or intracytoplasmic sperm injection type of ET catheter, cycles with good quality embryos and transferred embryos between two groups. The rate of both chemical and clinical pregnancy was higher in Group B compared to A, but the difference was insignificant (P = 0.09 and P = 0.1, respectively). Conclusion: It seems that there is no difference in the outcome by loading the embryo from microdrop or center-well dish.

Of more significance may be the 17% of blastocysts that contained both diploid and aneuploid cells. The fate of these embryos is unclear. It is possible that the aneuploid cells have a growth disadvantage or are eliminated by processes such as apoptosis, leading to a decline in their numbers as development progresses, ultimately resulting in a normal fetus. If this scenario is correct, some diploid–aneuploid mosaic blastocysts may be viable and might be incorrectly discarded if aneuploid cells were detected following TE biopsy.

nfluence of ovarian stimulation with HP-hMG or recombinant FSH on embryo quality parameters in patients undergoing IVF

BACKGROUND There are limited data on the impact of different gonadotrophin preparations on embryo quality.

METHODS This evaluation was part of a randomized, assessor-blind, multinational trial, conducted in 731 women undergoing IVF after stimulation with highly purified human menopausal gonadotropin (HP-hMG; MENOPUR) (n = 363) or recombinant FSH (rFSH; GONAL-F) (n = 368). Ongoing pregnancy was the primary end-point [HP-hMG 27% and rFSH 22%; odds ratio (OR) (95% confidence interval, CI) 1.25 (0.89-1.75)]. All 7535 oocytes retrieved were evaluated daily until day 3 (embryo transfer) in a blinded manner both by local site embryologists and a central panel of three embryologists.

RESULTS The proportion of top-quality embryos per oocyte retrieved was higher with HP-hMG (11.3%) compared with rFSH (9.0%) (P = 0.044) in the local assessment, but comparable in the central assessment (9.5 and 8.0%, respectively). Significant differences in favour of HP-hMG were observed for number of blastomeres and degree of fragmentation, while uniformity of blastomere sizes, localization of fragments, frequency of multinucleation and homogeneous cytoplasm were comparable between HP-hMG and rFSH. The live birth, ongoing pregnancy and ongoing implantation rates for top-quality embryos were higher with HP-hMG than rFSH [48 versus 32% (P = 0.038), 48 versus 32% (P = 0.038), 41 versus 27% (P = 0.032)]. Both the proportion of embryos with at least 50% surviving blastomeres after cryopreservation and embryos resuming mitosis were more frequent with HP-hMG compared with rFSH.

CONCLUSIONS Composition of gonadotrophin preparations used during ovarian stimulation has an impact on some embryo quality parameters. The capacity to implant of the top-quality embryos derived from stimulation with HP-hMG appears to be improved, although the mechanism needs to be elucidated.

Dosage nomogram for ovulatory IUI patients' first rFSH treatment cycle.

The aim of the stimulation was to achieve two follicles ≥18 mm and maximum one intermediate-size follicle (≥14 and <18 mm) on the day of hCG. The day of hCG was defined as the day the leading follicle reached a diameter of 18 mm. On the basis of a patient's body weight (kg) and total AFC, an individual starting dose can be identified.

Abstract

The current systematic review was aimed to assess the effectiveness of the zygote morphology evaluation in fresh in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) cycles. All available studies reporting on zygote morphology and clinical and/or biological outcomes were analyzed. Forty studies were included in the final analysis. Fourteen different zygote scoring systems were employed. Zygote morphology correlated significantly with embryo quality and cleavage, blastocyst stage, embryonic chromosome status, in a high proportion of the studies which assessed the specific outcome [15/25 (60%), 15/20 (75%), 7/8 (87.5%), 6/6 (100%), respectively]. On the other hand, only a reduced proportion of papers showed a statistically significant relationship between implantation, pregnancy and delivery/live-birth rates and zygote morphology score [12/23 (52.2%), 12/25 (48%), 1/4 (25%), respectively]. In conclusion, our findings demonstrate the lack of conclusive data on the clinical efficacy of the zygote morphology evaluation in fresh IVF/ICSI cycles, even if biological results showing a good relationship with embryo viability suggest a role in cycles in which the transfer/freezing is performed at day 1.

cAMP細胞內訊號傳遞與卵細胞發育有關

卵泡發育過程中，卵細胞會分泌inhibin, E2，抑制腦下垂體分泌FSH, LH

FSH會刺激卵細胞之adenylyl cyclase, 引發cAMP製造及細胞內訊號傳遞，及進一步卵顆粒細胞及卵細胞之發育
