Purpose Of Review:
Fertility preservation has recently gained a worldwide interest among fertility specialists, oncologists, and all healthcare providers. Thus, the protection against iatrogenic infertility caused by chemotherapy assumes a high priority. Specifically, the issue of endocrine prevention of gonadotoxicity is still a controversial subject.
Recent Findings:
During the last year, many publications on this subject appeared, swinging the pendulum toward the beneficial role of gonadotropin-releasing hormone agonist (GnRHa) cotreatment for fertility preservation despite gonadotoxic chemotherapy. Here, we summarize the recent publications on fertility preservation and minimizing chemotherapy-induced gonadotoxicity.
Summary:
More than 10 recent meta-analyses have concluded that GnRHa is beneficial and may decrease the risk of premature ovarian failure and increase the pregnancy rate in survivors. Furthermore, two recent international meetings of experts have concluded that GnRHa is effective and should be offered to every young woman facing gonadotoxic chemotherapy.

01:30Hormonal 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...

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
