👉 Abortion involves the termination of a pregnancy, typically occurring after fertilization but before the fetus reaches viability. The process begins with fertilization, where a sperm cell fuses with an egg, forming a zygote. This zygote undergoes rapid cell division, known as cleavage, transforming into a blastocyst, which implants in the uterine wall around six to seven days post-fertilization. At this stage, the embryo is considered early development and lacks a heartbeat. As the pregnancy progresses, the embryo develops into a fetus, characterized by the formation of major organs and structures. Abortion can occur through various methods, each targeting different stages of fetal development: chemical abortion uses hormonal agents to induce miscarriage, physical abortion involves medical procedures like dilation and evacuation (D&E) or methotrexate injection to terminate the pregnancy, and surgical abortion directly removes the fetus. Each method aims to halt fetal growth and prevent further development.
