What is the Origin of Chemotherapy-Induced Ovarian Failure?

The term is a clinical descriptor that emerged with the widespread use of systemic chemotherapy for various malignancies, particularly in premenopausal women. It bridges the fields of oncology and reproductive endocrinology, addressing a critical adverse effect of life-saving cancer treatment.

What is the Mechanism of Chemotherapy-Induced Ovarian Failure?

The mechanism of CIOF involves the direct cytotoxic action of chemotherapy drugs on the highly sensitive ovarian primordial follicles, which are essentially non-renewable. Alkylating agents are particularly damaging, causing irreparable DNA damage in the oocytes and granulosa cells, leading to follicular atresia and a rapid reduction in the total ovarian reserve. This irreversible loss of follicles subsequently results in a sharp decline in ovarian hormone production, specifically estradiol and progesterone.

Chemotherapy-Induced Ovarian Failure

Meaning

Chemotherapy-Induced Ovarian Failure (CIOF) is a significant clinical complication characterized by the premature cessation of ovarian function resulting from the cytotoxic effects of cancer treatment agents. This condition leads to the depletion of the ovarian follicle reserve, resulting in amenorrhea, infertility, and a state of hypoestrogenism, mimicking natural menopause but occurring at an unnaturally early age. The severity is highly dependent on the specific chemotherapy regimen, dose, and the patient’s age at treatment.
