The eggs are surgically removed from a woman's ovaries and placed in a carefully prepared broth called human tubal fluid. Six hours later, the husband's sperm cells are added. The evidence of fertilization was detected approximately 16 hours later. Later on, the scientists select four embryos that are actively dividing and carefully inserts them into the woman's uterus …

The events of early reproduction are among the most fascinating, most complex, but least understood in human biology. This class has taught me to share a fundamental desire for this significant process and has helped me understand the events that ensure the continuation of human life
