    Men with cancer rendered infertile by surgery, chemotherapy, radiation and hormone therapy that are needed to control or cure their disease are increasingly being offered the chance to preserve their reproductive potential through artificial reproductive technologies. Cryopreservation of sperm and testicular tissue have increasingly helped boys and men preserve their fertility. There is a growing subspecialty within reproductive medicine aimed at fertility preservation in this population. Furthermore, strategies are being developed that may in the future revolutionize the approach to such patients. Written by international authorities in the field of fertility preservation, this comprehensive book is aimed at clinicians dealing with male cancer patients, in particular, urologists, andrologists, oncologists, pediatricians and nursing staff as well as clinicians in reproductive endocrinology. The text reviews the impact of cancers and their treatment on male fertility, the available fertility preservation strategies and post-treatment management.

    Summary

    The X chromosome may be as important as the Y in determining male fertility potential. By refining the analysis of the particular recombination abnormalities in infertile men, this study confirmed that there may be decreased chromosomal pairing quality as well as recombination frequencies in men with non-obstructive azoospermia. Documentation of the normal variability in recombination is a prerequisite for the understanding of changes observed in abnormal situations, such as non-disjunction or a chromosome re-arrangement. It appears that G-group as well as sex chromosomes are most susceptible to having no recombination foci and thus are more susceptible to non-disjunction during spermatogenesis. The growing knowledge of the close relationship between germ cells and stem cells, and the successful manipulation of these cells in vitro, has tremendous implications not only for the treatment and cure of male infertility but also for a host of other medical diseases in the future.
