Pemanfaatan Teknik Assisted Hatching Dalam Meningkatkan Implantasi Embrio

E-59, Bogor 16128 [email protected] (Diterima 29 September 2016 – Direvisi 12 Januari 2017 – Disetujui 27 Februari 2017) ABSTRACT Gestation is the main goal for in vitro fertilization. The embryo that has been developed outside the body will be transferred directly into uterus leading to the process of hatching, implantation, and pregnancy. However, approximately 85% of embryos that have been transferred were failed to implant and it might be caused by hatching failure. Hatching is the process of releasing embryo from zona pellucida. If this process does not occur, it will cause pregnancy failure. Assisted hatching is a mechanism that dealing with thinning, slicing or artificially making holes in the zona pellucida to improve hatching. The process can be applied both in fresh or frozen embryos. This review describes various methods in assisted hatching such as enzymatic, chemical, mechanical, and laser beam as well as their advantages and disadvantages. Generally, some researches show that the technology of assisted hatching can improve the percentage of hatching and implantation of the embryo. However, in spite of the benefits, there are such weaknesses find in the zona pellucida of the embryo that has been manipulated such as toxic hazard medium, the risk of damage to the blastomeres or monozygotic twinning. -

Is It Time to Abandon Embryo Byopsy Techniques?”
FACULTY OF SCIENCES DEGREE IN BIOLOGY FINAL PROJECT ACADEMIC YEAR (2019-2020) TITLE: EMBRYONIC ANEUPLOIDY DETECTION BY NON-INVASIVE METHODS, A REVIEW. “IS IT TIME TO ABANDON EMBRYO BYOPSY TECHNIQUES?” AUTHOR: ÁNGEL MÁÑEZ GRAU 2 SUMMARY: Assisted reproduction is the group of techniques that help people to deal with fertility and sterility problems. These techniques have the goal of achieving a live birth, in which a healthy baby is born. To ensure that the baby is healthy and to avoid any type of pregnancy or birth defects or problems, a genetic test can be performed to the embryo, prior to the transfer and implantation in the mother. This is called the preimplantation genetic test (PGT). The test can be done to detect structural rearrangements (SR), monogenic diseases (M) or aneuploidies (A), and it is mostly done by performing an embryo biopsy on the 5th day of development, following by different genetic approaches. This technique generates lots of controversy, due to ethical and embryo viability implications, because it is not known if it significantly affects the embryo. So, to avoid this kind of problems, non-invasive techniques (niPGT) have been developed. The niPGT relies on the presence of genetic material in the embryo spent culture medium, which is analysed instead of the embryo trophectodermal cells. This techniques has several advantages over the invasive ones. The clearest one is that there is no need to harm the embryo with lasers or pipettes. The need of experimented technicians and expensive laboratory equipment are not required for this type of technique, so it makes it easier and cheaper. -

The Impacts of Laser Zona Thinning on Hatching and Implantation of Vitrified-Warmed Mouse Embryos
Lasers in Medical Science (2019) 34:939–945 https://doi.org/10.1007/s10103-018-2681-8 ORIGINAL ARTICLE The impacts of laser zona thinning on hatching and implantation of vitrified-warmed mouse embryos Zhengyuan Huang1 & Jinghao Liu2 & Lei Gao1 & Qingrui Zhuan1 & Yuxi Luo 1 & Shien Zhu1 & Kaiyu Lei3 & Xiangwei Fu1 Received: 3 September 2018 /Accepted: 2 November 2018 /Published online: 13 December 2018 # Springer-Verlag London Ltd., part of Springer Nature 2018 Abstract Embryo vitrification has advantages in assisted reproduction yet it also induces zona hardening. Laser zona thinning (LZT) is considered as a solution yet its efficacy and security have not been well studied. In this study, we used vitrified-warmed morulae from 2-month-old and 10-month-old ICR female mice as model to investigate the impacts that LZT treatment brings to the in vitro hatching process and implantation by analyzing hatching rate, implantation rate, and blastocyst quality. The results showed that the fully hatched rate was significantly higher after LZT treatment for both young (25.7% vs. 16.2%, P < 0.05) and aged (36.6% vs. 13.2%, P < 0.01) mice. For zona-thinned morulae in young mice, its onset of hatching occurred earlier (28.6% vs. 8.8%, P < 0.01) at D4 and with a greater percentage of U-shaped hatching at D5 (48.3% vs. 33.0%, P < 0.05). LZT treatment did not induce expression change of apoptosis-related genes in all groups (P > 0.05), but for young mice, the total cell number of day 5 blastocyst in zona-thinned group was significantly less than that of the control group (40.6 ± 5.1 vs. -

A Comparison of the Clinical Effects of Thinning and Drilling on Laser-Assisted Hatching
Lasers in Medical Science https://doi.org/10.1007/s10103-020-03230-9 REVIEW ARTICLE A comparison of the clinical effects of thinning and drilling on laser-assisted hatching Yujiang Wang1 & Chuangqi Chen1 & Jiaying Liang1 & Lin Fan 1 & Dun Liu1 & Xiqian Zhang1 & Fenghua Liu1 Received: 23 April 2020 /Accepted: 22 December 2020 # The Author(s) 2021 Abstract To systematically investigate the effects of two methods used for laser-assisted hatching (LAH) on clinical outcomes after day 4 (D4) on frozen-embryo-transfer (FET) cycles. Data from 11471 infertile patients who underwent FET cycles between January 2014 and October 2018 was retrospectively analyzed. The 1410 patients who met the inclusion criteria were further categorized into two groups based on the hatching procedure used: the thinning laser-assisted hatching group (T-LAH, 716 patients), and the drilling laser-assisted hatching group (D-LAH, 694 patients). The baseline characteristics of the patients were consistent between the two groups. However, the rates of implantation and clinical pregnancy were significantly higher in the T-LAH group compared to the D-LAH group (32.73% vs. 29.09%, P < 0.01, and 50.98% vs. 43.95%, P < 0.01). The proportion of live birth was also higher in the T-LAH group, but the difference was insignificant (39.11% vs. 36.89%, P > 0.05). Moreover, there were no significant differences in rates of miscarriages, multiple pregnancies, ectopic pregnancies, preterm births, and congenital disabilities between the two groups. Nonetheless, significantly higher rates of implantation and pregnancy were reported in the T- LAH group compared to the D-LAH group among patients aged <35 years, patients with at least one previously failed cycle, and patients with an endometrial thickness of 8–10 mm. -
Oocyte Freezing Consent
Female Patient’s Name: _______________________ Social Security #: ___________________ Partner’s Name: _____________________________ Social Security #: ___________________ Karande & Associates, S.C. doing business as InVia Fertility Specialists ASSISTED REPRODUCTIVE TECHNOLOGIES PROGRAM OOCYTE CRYOPRESERVATION - CONSENT Description, Explanation and Informed Consent We, _________________________________________, understand that cryopreservation (freezing) of human oocytes is a procedure that can be utilized to preserve oocytes so that they may be fertilized and transferred at a later time. The members of INVIA FERTILITY SPECIALISTS’s staff, along with affiliated Professional Staff, are known as the “A.R.T. Team”. We understand that by signing this form, we evidence our consent to the use, by the A.R.T. Team, of assisted reproductive technology procedures in connection with our participation in the Assisted Reproductive Technologies Program. It is our understanding that cryopreservation will be performed by the embryologists at InVia Fertility Specialists. Description and Explanation of Program Embryos have been successfully cryopreserved in fertility clinics throughout the past decade. More recently, oocyte cryopreservation has been performed with variable success. Oocyte cryopreservation provides patients with the option of “oocyte banking”, or freezing their eggs for use at a later date. This is especially beneficial for oncology patients or patients wishing to postpone pregnancy until later years. It will also allow oocyte donors to be stimulated independent of recipients. Oocyte cryopreservation also benefits those patients who wish to fertilize only a limited number of oocytes due to religious or ethical reasons. Oocyte cryopreservation may also be employed if for some unexpected reason the male partner cannot produce a semen specimen during the day of egg retrieval.
