THE FASCINATION The male germ cell is the only cell of the human organism that leaves the body when it has achieved its final, highly sophisticated structure and properties. The male germ cell is designed for one purpose only: to reach the female gametes and to fertilize them. The various stages in the development of the male germ cell are characterized by proliferative phases, by the recombination of the maternal and paternal chromosomes, and by the differentiation and development of a specialized transport vehicle, the spermato- zoon. Furthermore, the establishment of a special pool of stem...

Papers from a December 1996 symposium present the latest research on fundamental aspects of sperm production and maturation and the destiny of spermatozoa within the female reproductive tract.

The first international forum on relaxin was a workshop held in Hawaii in 1980. This was followed by the Kroc Foundation conference in Santa Ynes, California in 1981 and then the First International Congress on the Hormone Relaxin in Florence in 1982. After a hiatus of several years, the Second International Congress on the Hormone Relaxin was held in Adelaide in 1994. Since that time, the enormous advances in molecular biology and protein chemistry have led to a stellar growth in relaxin research. Novel sites of action of the hormone have been elucidated, numerous new mammalian primary...
