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. Therefore, it is advisable to perform assisted hatching in certain cases that tends to face obstacles during the process of hatching such factors as age, embryo quality, the thickness of the zona pellucida and the number of failures in the in vitro fertilization program.

Abstract

Penelitian ini bertujuan mengetahui pengaruh suhu dan waktu penyimpanan ovarium terhadap tingkat fertilisasi oosit secara in vitro pada  domba. Ovarium dibawa dari rumah potong hewan (RPH) dalam medium NaCl fisiologis pada suhu yang berbeda yaitu 27-28° C, 36-37° C, dan 4° C. Oosit kemudian dikoleksi dari setiap kelompok berdasarkan waktu penyimpanan yang berbeda yaitu 2-4, 5-7, dan 8-10 jam setelah domba dipotong. Oosit dikoleksi dan dimaturasi secara in vitro dalam inkubator 5% CO2, 38,5°C selama 28 jam. Oosit kemudian difertilisasi ke dalam drop spermatozoa selama 14 jam dalam inkubator CO2 5%, 38,5 C. Tingkat fertilisasi dievaluasi berdasarkan jumlah pronukleus yang terbentuk. Tingkat fertilisasi oosit yang dikoleksi dari ovarium yang disimpan pada suhu 27-28° C tidak berbeda dengan tingkat fertilisasi oosit yang disimpan pada suhu 36-37° C dan pada suhu 4° C, 2-4 jam setelah kematian hewan (masing-masing 53; 66,66; dan 63%) (P0,05). Tingkat fertilisasi oosit mulai mengalami penurunan pada tiga kelompok perlakuan setelah ovarium disimpan selama 8-10 jam, tingkat fertilisasi oosit yang disimpan pada suhu 27-28° C; 36-37° C; dan suhu 4° C masing-masing berturut-turut sebesar 9,8; 22,22; dan 12,24%. Dari hasil penelitian disimpulkan bahwa penyimpanan ovarium pada suhu 27-28° C dan 36-37° C selama 5-7 jam dapat mempertahankan kompetensi oosit dibandingkan dengan penyimpanan pada suhu 4° C.
