In this report, emphasis is placed on major research developments in the reproductive sciences, their impact on the health of individuals as well as on that of society, and on current trends that may provide new opportunities for future research in fertility and infertility. In the first section, major developments in the reproductive sciences are discussed in the areas of: (1) endocrine regulation of reproductive processes; (2) female reproductive system; (3) male reproductive system; (4) gamete biology; (5) early development of the embryo; and (6) implantation of the embryo. The second section explores the impact of recent research on health and disease. Included are discussions on: (1) male and female infertility; (2) fertility regulation; (3) relief of dysemenorrhea; (4) synchrony of estrus in animal husbandry; (5) management of breast cancers; (6) endometriosis; (7) hyperprolactinemia; and (8) disorders of sexual differentiation. The final section cites areas of future investigation in: (1) neuroendocrine control of reproduction; (2) mechanism of action of reproductive hormones; (3) reproduction peptides of gonadal origin; (4) regulation of follicular growth and ovulation; (5) regulation of fertility events in the male; (6) in vitro fertilization and embryo transfer; (7) mechanism of implantation; (8) toxins affecting reproduction; and (9) development of hybridomas. A selected bibliography of 58 references is included. (JD)
