Ovarian stimulation is the starting point of reproductive medicine but the procedure can result in adverse reactions particularly the dangerous ovarian hyperstimulation syndrome. Fully revised in line with modern practice of ovarian stimulation, this new edition is divided into six sections that cover mild forms, non-conventional forms, IVF, complications and their management, alternatives, and the practicalities of procedures. All aspects of ovarian stimulation are discussed including the different stimulation protocols from which to choose, the management of poor responders and hyper-responders, as well as stimulation in patients with PCOS. Comprehensively reviewing the modern approach to ovarian stimulation, the alternative procedures are also described, both in IVF and other methods of assisted reproduction.
