This volume, and its companion volume on the spermatozoon, provide an authoritative and wide ranging account of the gametes and their reproductive role and function in humans. Acknowledged authorities from around the world contribute a detailed and timely account of the oocyte. The volume starts with an evolutionary perspective before focusing on the molecular and cellular biology of the oocyte and its structure and function. The development and maturation of the oocyte is fully dealt with to include the endocrine and paracrine regulation of ovarian function. Practical issues such as oocyte storage and ovarian stimulation are also fully covered. The causes of female infertility are also an important theme. The volume concludes with a thought provoking chapter on ethical considerations. The volume will be an essential source of information for all clinicians and scientists with an interest in human reproduction.
