Increase in success of cancer treatment with advancement in the screening, prognosis and diagnosis protocols have significantly improved the rate of cancer survivorship. With the declining cancer mortality, however, the cancer survivors are also subjected to the adverse consequences of chemotherapy, particularly in the female reproductive system. Recent studies have shown the sensitivity of the ovarian tissue to the chemotherapeutic drugs-induced toxicity. Several in vitro and in vivo studies have assessed the toxic effects of chemotherapeutic drugs. The most frequently used chemotherapeutic drugs such as doxorubicin, cyclophosphamide, cisplatin and paclitaxel have been reported to cause ovarian damage, diminution of follicular pool reserve, premature ovarian failure and early menopause, resulting into declining fertility potential among females. The chemotherapy often employs combination of drug regimen to increase the efficacy of the treatment. However, the literature mostly consists of clinical data regarding the gonadotoxicity caused by anticancer drugs but there lacks the understanding of toxicity mechanism. Therefore, understanding of the different toxicity mechanisms will be helpful in development of possible therapeutic interventions for preservation of declining female fertility among cancer survivors. The current review comprehends the underlying mechanisms of female reproductive toxicity induced by the most commonly used chemotherapeutic drugs. In addition, the review also summarizes the recent findings related to the use of various protectants to diminish or at least in managing the toxicity induced by different chemotherapeutic drugs in females.
