This book has proved itself up to our expectations for precision of information, to the point, knowledge-based practical tips and as a ready reckoner. It has surely helped several fertility specialists to improve results of intrauterine insemination, which is truly a credit in this era of in vitro fertilization and has proved to be a boon to the patients too residing in remote areas and unable to afford sophisticated ART.Intrauterine insemination (IUI) is a conventional, cost-effective, and competent method of infertility management. It has been blamed for poor results because of nonstandardization of the entire therapy. In this book, we have tried to take into consideration the practical aspects of all different steps of IUI, namely indications of IUI, preprocedure work-up, ovulation-induction protocols, ultrasound monitoring, technique of IUI, laboratory setup, semen preparation, luteal phase support, and complications of IUI. Each step has been discussed keeping practicing gynecologists in mind. It is a crisp, precise, and concise book covering the entire subject with clear understanding and with a strong base of our experience of more than 10,500 conceptions with IUI in patients with long-term infertility.
