Abstract
The odds of preserving gonadal function after gonadotoxic chemotherapy are signiï¬cantly better for prepubertal girls than for boys. Although ovarian function has been preserved in most long-term female survivors treated prepubertally for lymphoma,but only in approximately half of the similarly treated adult reproductive-age women, it is clinically logical to generate a tem- porary and reversible prepubertal milieu before and during the gonadotoxic chemotherapy. Many groups of clinicians have been using gonadotropin-releasing hormone agonist (GnRHa) cotreat- ment for minimizing the gonadotoxic effects of chemotherapy, by simulating a prepubertal hormonal milieu, with the rationale that preventing premature ovarian insufï¬ciency (POI) is preferable to treating it. However, reported results addressing this strategy have been conflicting, and several major international guidelines still consider it experimental.
