31 Οκτ 2023 · Oogenesis occurs in the outermost layers of the ovaries. As with sperm production, oogenesis starts with a germ cell, called an oogonium (plural: oogonia), but this cell undergoes mitosis to increase in number, eventually resulting in up to one to two million cells in the embryo.
Oogenesis - the process by which female germ cells develop into mature eggs, or ova - is a complex process involving many important elements of developmental and cellular biology: from cell-cell interactions, complex signalling cascades, specialized cell cycles and cytoskeleton organization.
Oogenesis—the differentiation of the ovum—differs from spermatogenesis in several ways. Whereas the gamete formed by spermatogenesis is essentially a motile nucleus, the gamete formed by oogenesis contains all the materials needed to initiate and maintain metabolism and development.

“This book reviews the process of oogenesis, including essentially all aspects spanning germ cell formation to ultimate atresia during menopause. … The book is written for both scientists and practitioners in the field of ART, likely including clinicians and embryologists. …
The entire process of germ cell differentiation takes place in the two ovotestes, which are each composed of a distal tip cell and five pairs of sheath cells (Figure 1.1; McCarter et al., 1997; Hall et al., 1999, and see www.wormatlas.org for a concise review).
By incorporating these detailed processes and interactions, the chapter provides a thorough understanding of oogenesis, folliculogenesis, the ovarian cycle, and their hormonal regulation, fulfilling the specified learning outcomes comprehensively.
