Abstract:
This study was conducted to report the clinical-pregnancy outcome after vitrification of the blastocysts produced from in vitro maturation cycles. The survival rate after thawing was 92.0% (92/100). The clinical-pregnancy and implantation rates were 43.8% and 23.6%, respectively. These results suggest that the blastocyst-stage embryos produced from in vitro maturation cycles can be safely cryopreserved through vitrification.

01:24In Vitro Fertilization
In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...

01:33Cleavage and Blastulation
After a large-single-celled zygote is produced via fertilization, the process of cleavage occurs while zygotes travel through the uterine tube. Cleavage is a mitotic cell division that does not result in growth. With each round of successive cell division, daughter cells get increasingly smaller.
