Infertility is defined as the inability to become pregnant (in a woman) or cause a pregnancy (in a male). The purpose of this book is to provide a stepwise approach to the diagnosis and treatment of an infertile couple. It describes the detailed workup, such as hormonal evaluation and transvaginal sonography, that is essential for accurate diagnosis. The various options available to the clinician, from ovulation induction to ovum donation and cryopreservation, are also explained. The possible complications as well as failures are also described. It is important to actively suggest adoption as an alternative when treatment fails. The clinician should always offer this option to prospective parents
