Abstract:
Numerous pathologies and their treatments may alter ovarian reserve in women and girls and may harm their future fertility. Oocytes cryopreservation techniques may be used in a limited number of cases, excluding young patients. We hereby report results obtained with our and other teams' ovarian tissue vitrification techniques. This new approach can be offered to young patients before puberty and should not delay both chemotherapy and radiotherapy when needed. Major drawbacks include potential alteration of ovarian reserve, as well as recurrence of the original malignancy. The later can be circumvented using in vitro maturation techniques. It is important to discuss fertility preservation opportunities with every woman or girls facing potential premature ovarian failure.

Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
