The Role of Peptides and Amino Acids as Neurotransmitters

Many of the chapters dealing with humans are somewhat technical and of interest only to those involved in applying these techniques to patient care. Yet, the chapter by A. Thebault et al. on the effects of clomiphene and HCG on ovulation as well as the chapter by L. Mettler et al. on human in vitro fertilization are extremely informative and demonstrate the marriage of basic and clinical science, amply illustrated in a nascent field. The final portion of this monograph on embryo transfer is the most interesting in that it deals with the future potential of the fieldthe most perplexing involving embryo transplant and implantation This section deals at length with freezing of gametes and embryos as well as open uterine procedures and transcervical procedures. The material is mainly based on animal data but the reader does not have to stretch his imagination far to see how this will have tremendous application to humans. This is a well-rounded, complete text of interest to all, but expecially to those actively involved in this important and growing field.
