Book Description
This atlas provides ultrastructural morphological images of human spermatozoa. Sperm morphology plays an essential role in sperm-oocyte interactions and early embryonic development, and human sperm ultrastructural morphology offers a valuable reference tool for assessing certain etiologies of male infertility and reproductive failure. However, the ultrastructural morphology of human sperm has not been systematically evaluated or thoroughly described in the literature. Using 470 original and unpublished images, the book shows various ultrastructural morphological phenotypes; defects of the sperm head, neck, middle piece, principal piece, and terminal piece; as well as artefacts of sperm ultrastructural morphology and phenomena related to inadequate preparation, demonstrating many sperm phenotypes and surface structural appearances for the first time. As such, it helps researchers and practitioners in andrology, reproductive medicine, and reproductive pathology gain a better understanding of human sperm ultrastructural morphology.

Book Description
This atlas provides valuable information on crucial aspects of sperm examination as well numerous meaningful color illustrations. It discusses successful evaluation of the sperm morphology and the cellular elements other than spermatozoa, enabling readers to unambiguously interpret seminal cytologic images and compare reports for diagnostic, therapeutic and prognostic purposes. With its extensive collection of colored images, the book is intended as a reference resource for students and technicians in the field of andrology as well as practitioners and clinicians in andrology, urology, pathology, IVF and other ART programs

Book Description
The suggestion of Max Knoll that an electron fascinated by the numerous SEM photographs, the wealth of information and the enthusiasm of the microscope could be developed using a fine scanning researchers covering a variety of disciplines. All aspects beam of electrons on a specimen surface and recording the emitted current as a function of the position of the of the female and male genital tract have been covered, beam was launched in 1935. Since then several culminating in the prizewinning award showing the in investigators and clinicians have used this concept to vitro fertilized human egg. develop techniques now known as scanning electron In clinical diagnostics SEM also proved to be a microscopy (SEM) and scanning transmission electron valuable complementary technique, shedding new light microscopy (STEM). The choice to study the female on oncology, the pathogenesis of tubal disease and the reproductive organs was a logical one because cells and maturation process of the placenta. Future research has tissue samples can be sampled relatively easily; still to be accomplished; e.g. quantification of SEM furthermore, these cells and organs are influenced photographs for meaningful and sound biological, continuously by the cyclic production of hormones. scientific and statistical evaluation in diagnostic This atlas demonstrates the state of the art in 1983. gynecology, obstetrics, andrology and oncology.

Book Description
The analysis of ejaculate, known as the spermiogram, is the crucial investigative technique in the andrological check-up for childlessness. Althoug other impor tant factors such as medical history, physical examination, hormone analysis and tests, biochemical, microbiological, immunological, and genetic tests, and histological and histochemical investigations must all be considered before a final assessment can be made of male fertility, the spermiogram is the guiding factor in estimating the prospects of fertility. Furthermore, the improvement in insemination techniques in recent years and the development of in vitro fertilization have enhanced the importance of the accurate analysis of sperm morphology and function. In view of the multiplicity of andrological investigative techniques listed above, urologists, gynecologists, physicians specializing in endocrinology and immunology, general practitioners, pathologists, and dermatologists are routin ely involved in semen analysis today. We hope in this book to address people working in all these different medical specialities. Having regard for the requirements of daily practice, we will intentionally restrict ourselves to the spermiogram, which we hope to present step by step by means of a large number of illustrations. A substantial part of the book is devoted to the morphological assessment of normal and pathological forms of spermatozoa and other cellular elements, in the form of generously illustrat ed atlas. Dr. Rovan has given us outstanding assistance in preparing the majori ty of photomicrographs.

Book Description
Developmental biology has been transformed recently by discoveries in the fields of molecular biology, cell biology, and immunology. New ways of manip ulating mammalian development are uncovering control mechanisms and ena bling us to apply them in solving practical problems in animal production and human health. This book outlines some of these new manipulations and how they have contributed to the present state of developmental biology. Chapter 1 describes gene transfer by micro injection of cloned recombinant DNA into zygotes. Although the factors that affect transformation frequencies and integration sites are still unknown, such techniques offer a number of exciting prospects. Research models for human disease coula be artificially created and desirable characteristics in agricultural animals could be - hanced. . The theme of cell-to-cell transfer is continued in Chapters 2 and 3. Chapter 2 describes pronuclear transplantation by Sendai virus-induced fusion of the karyoplast with the enucleated embryo. Using this procedure, it has been dem onstrated that both male and female genomes are essential for normal develop ment, although the reason for this is not yet understood. Chapter 3 describes studies on the fusion of whole oocytes. .

Book Description
By integrating novel developments in both contact linguistics and morphological theory, this volume pursues the topic of borrowed morphology by recourse to sophisticated theoretical and methodological accounts. The authors address fundamental issues, such as the alleged universal dispreference for morphological borrowing and its effects on morphosyntactic complexity, and corroborate their analyses with strong cross-linguistic evidence.
