In vitro fertilization (IVF) is a fertilization method where an egg is combined with sperm outside the body, typically in a controlled laboratory environment using a test tube or specialized dish.
This process creates a zygote or early-stage embryos containing up to 8 blastomeres. Following fertilization, these embryos can be transferred back into the fallopian tube or directly into the uterus to support further development and potentially establish a pregnancy.
IVF is a common assisted reproductive technology used to assist individuals or couples experiencing infertility or difficulties in conceiving naturally.
