Explain the fertilization process used in Brave New World. How does the Hatching and Conditioning Centre acquire the necessary ovum and spermatozoa?

The hatching and conditioning center is a site for genetic engineering. Students see different machines and methods for the development and maintenance of embryos. The scientist takes an ovary, collects and fertilizes the sperm, pumps the eggs up to 96 times, and then develops the embryos into the bottles. Predestinators then agree about the future role of each embryo in culture, assigning each human being basically a future task. The eggs are taken by women and only the good ones are used. Sperm is obtained from different men's rates.
