Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - In 1954, when I obtained my B. Sc. (Honours School) degree in Zoology, I was asked by my advisor, the late Professor Vishwa Nath, to make comparative cytological studies of oogenesis in birds for my M. Sc. (Honours School) thesis submitted to the Panjab University in 1956. Using the classical techniques of cytology, I studied the various aspects of follicle growth and atresia in five species of birds. Professor Vishwa Nath, who himself devoted most of his life to the study of the comparative cytology of gametogenesis in animals, was so much impressed by my findings on avian oogenesis that he asked me to continue my research work for the Ph. D. degree under his supervision. During my research work on avian oogenesis, I became very much interested in further comparative study of ovarian follicles in vertebrates and thus decided to make comparative, morphological and histochemical studies of ovarian follicles in reptiles, birds and mammals. Actually, very little information was available in this regard in 1957 when I started working for the Ph. D. degree. In subsequent years, I and my numerous dedicated and highly motivated M. Sc. and Ph. D. students con tinued to make comparative, morphological, histochemical, biochemical and physiological studies of ovarian follicles in all groups of vertebrates. In connection with the subject of this book, I would like to make special mention of my two brilliant students, namely Dr. S. K. Varma and Dr. R. K.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - The spermatogenesis and spermatozoa of mammals are of funda mental interest to a wide variety of academic and scientific disci plines; zoologists keep up interest in comparative biology of sper matogenesis and spermatozoa in different groups of mammals for determining their phylogenetic interrelationships. Therefore, during the past 15 years, a wealth of reviews and papers have been published on the morphology (including ultrastructure), histochemistry, auto radiography, biochemistry (including immunology), and cell physiol ogy of the seminiferous epithelium including Sertoli cells, spermato genesis and spermatozoa in mammals. Hormonal regulation of sper matogenesis also forms the subject to numerous studies. Research in this area of reproductive biology continues at a remarkable rate, and new and significant information appears daily in a wide range of journals, published symposia, and specialist reviews. The scattered nature of this information makes it difficult for a scientist, student or andrologist to go through even a small fraction of these publications on the biology of spermatogenesis and spermatozoa and so obtain a general oversight of current activity and new advances. Actually, very little attempt has been made previously to summarize and inte grate the vast information which has become available as a result of use of modern techniques of microscopy, surface topography, histo chemistry, autoradiography, biochemistry, biophysics, immunology, molecular biology, in vitro systems, etc. Much-needed interdisciplin ary approach in biology of seminiferous epithelium, spermatogenesis and spermatozoa is very difficult and thus lacking.
