More than 4 decades have passed since the birth of the first in vitro fertilized baby in 1978. The use of assisted reproductive technology (ART) to overcome infertility has increased steadily with the simultaneous increase in the number of fertility centers in every part of the world. Access to infertility clinics is playing an important role in the treatment of different forms of infertility (like tubal disease, ovarian aging, or ovarian dysfunction). This book captures the state of current and recent advances in assisted reproduction technology in humans and livestock in an easy and comprehensive way for non-experts and learners. 10 chapters cover the biology of reproduction, and male ART methods (sperm retrieval and freezing) and female ART methods (oocyte activation, and cryopreservation), and finally embryo ARTs (assisted hatching and cloning techniques) with simple definitions and explanations. Tips to overcome problems are also presented where appropriate along with references for further reading. This book is a simple primer for students who are involved in courses in embryology or reproductive technologies as part of programs in biology, biotechnology, medicine and physiology.
