The use of the natural cycle for in vitro oocyte maturation and subsequent IVF is outside the scope of this chapter and is covered in Chapter 8. 43 44 Healy et al. HUMAN OVARIAN PHYSIOLOGY The initiation of follicular growth is a continuous process that is believed to not depend on hormonal stimulation. About 50 follicles each day begin to grow in the human ovaries. Most follicles undergo rapid atresia. This total growth phase occurs over approximately 90 days or over three ovarian cycles. However under the hormonal changes in the late luteal phase and the beginning of the new cycle a group of follicles will respond to small rises in serum follicle-stimulating hormone FSH by processing
