Current Topics in Molecular Endocrinology. Hormonal Regulation of Spermatogenesis.

Current Topics in Molecular Endocrinology. The conference represented by this book was made possible by support from NICHD and a planning committee headed by Dr. Richard Sherins.

The plasma membrane may play a vital role in the regulation of cell division by affecting the transport of essential nutrients into the cell, and by acting as the transmitter and transducer of signals arising from cell-cell interactions. Uncontrolled growth could result from abnormalities in transport regulation, or in aberrant sensitivity to external signals which normally regulate cell division (2,8).

General Principles of Regulation of Spermatogenesis. FSH is an Important Regulator of Sertoli Cell Proliferation. Although the principles of the hormonal regulation of spermatogenesis have been established decades ago, the recently acquired genetic information, in particular from human mutations of gonadotropin and gonadotropin receptor genes, and from genetically modified mouse models, have advanced our knowledge about the molecular events involved in the regulation of spermatogenesis.

Hormones such as testosterone, FSH and luteinizing hormone (LH) are known to influence the germ cell .

Hormones such as testosterone, FSH and luteinizing hormone (LH) are known to influence the germ cell fate. Their removal induces germ cell apoptosis. Proteins of the Bcl-2 family provide one signaling pathway which appears to be essential for male germ cell homeostasis. In addition to paracrine signals, germ cells also depend upon signals derived from Sertoli by direct membrane contact. Somatostatin is a regulatory peptide playing a role in the regulation of the proliferation of the male gametes.

Hormonal regulation of spermatogenesis. ROBERT W. HOLDCRAFT and ROBERT E. BRAUN. Figure 1. Hormonal regulation of spermatogenesis Most hormones shown can have both positive and negative effects, either at the level of receptor zation or through activation and repression of down-stream targets. GnRH, gonadotrophin releasing hormone; LH, luteinizing hormone; FSH, follicle stimulating hormone; T, testosterone.

Normal testicular function is dependent upon hormones acting through endocrine and paracrine pathways both in vivo and in vitro. Sertoli cells provide factors necessary for the successful progression of spermatogonia into spermatozoa.

The conference represented by this book was made possible by support from NICHD and a planning committee headed by Dr. Richard Sherins. Two general areas of research are included: the first encompasses steroid hormone synthesis, metabolism and transport in the testis; and the second relates to hormonal regula­ tion of the seminiferous tubule with special emphasis on the con­ trol of Sertoli cell function. In addition, there are sections on the purification of unique testicular proteins and morpho­ logical studies with particular emphasis on the Sertoli cell. We would like to express our sincere thanks to Dr. Sherins and his staff at NICHD and to all of the people at the University of North Carolina who participated in the Conference arrangements, to Dr. Judson J. Van Wyk, Chief of the Pediatric Endocrinology Division, and Dr. H. Stanley Bennett, Director of the Laboratories for Reproductive Biology. Our very special thanks to Mrs. Carolyn Jaros for her help in handling the local arrangements. Mrs. Martha Byrd and Mrs. Linda Rollins typed the manuscripts. Miss Leslie Wells and Mr. Albert Smith kindly assisted in proof reading, and Dr. Elizabeth Wilson gave much help with the final editing process. To all of these people, we are most grateful.
