An embryo is formed when a sperm cell fertilizes an egg cell during the process of conception. This typically occurs in the fallopian tubes of a female's reproductive system. Once fertilization happens, the resulting zygote undergoes several cell divisions and develops into a multi-cellular structure known as a blastocyst before implanting itself into the uterine lining. This marks the beginning of embryonic development.
