A Color Atlas for Human Assisted Reproduction
Featuring more than 300 full-color photographs, this atlas is a comprehensive guide to the complex procedures used in assisted reproduction. It shows readers how to utilize the latest technologies and correlates the laboratory and clinical components of assisted reproduction. The book depicts oocytes, embryos, and blastocysts at various stages of division and offers guidelines for assessing oocytes and embryos. The authors give detailed instructions on ovarian stimulation, intracytoplasmic sperm injection, assisted hatching, cryopreservation, extended in vitro culturing, preimplantation genetic diagnosis, and embryo transfer techniques. Close attention is also given to assessment of oocytes and embryos from patients with endometriosis and other pathologies.
The Cryptorchid Testis
Current knowledge concerning both morphological and functional cryptorchid-related alterations in the various testicular compartments is summarized in this valuable new publication. Damage to the germinal epithelium and resulting infertility in both humans and experimental animals as well as the degree of damage to the different stages of germ cell development is discussed. In addition, information concerning hormonal therapy and orchidopexy to reverse cryptorchid-related damage is provided. Morphological alterations in Sertoli and Leydig cells is discussed in terms of cellular hypertrophy and hyperplasia, alterations in organelle number and characteristics as well as changes in cell-cell junctional complexes. Changes in Sertoli cell and Leydig cell function, including gonadotropin binding, steroidogenesis and other metabolic alterations is also outlined,as well as the influence of altered testicular function on subsequent hypothalamic-pituitary changes. Vascular disruption, the potential role of paracrine substances and direct thermal damage, all of which may be responsible for the resulting detrimental changes in one or more testicular compartments, are considered.
