In traditional IVF procedures, the first step involves medication to stimulate the production of a sufficient number of egg cells. Depending on the specific stimulation protocol, different medications are administered to prevent premature ovulation. Once an adequate number of follicles have matured, a trigger injection is given to finalize the maturation of egg cells, marking the crucial moment for egg retrieval. Following retrieval, sperm and eggs are incubated together in the laboratory, and fertilization takes place through the injection of sperm directly into the eggs.
