Springer has published the first practical guide to various IVF therapies, both with and without stimulation. The book presents the fundamentals of IVF treatments, describing their clinical applications, costs, risks, success rates, and much more in approximately 300 pages. It also includes around 30 studies conducted by the IVF Naturale Center in Bern. Two large, similar centers in Japan and New York also present their treatment approaches. This English-language textbook, which should be largely understandable even for laypeople, is available in bookstores. A new edition is planned for 2028, the year in which Louise Brown, the world's first IVF child conceived through natural cycle IVF, turns 50.
