Abstract:
High dose cytotoxic drug combinations as well as radiotherapies to the whole body, the pelvic region and the head ovarian are associated with a risk of gonadal damage. In men, cells responsible for sperm production are most prone to damage, but testosterone production is usually preserved. In women, cancer treatments are known to accelerate the disappearance of primordial follicles, prevent ovarian follicle growth and increase fibrosis. This decreases the non-regenerable pool of oocytes. In young women, the ovaries may function well shortly after cancer treatments, whereby getting pregnant is possible. However they are in inreased risk of premature menopause.
Insights
Cancer treatments like chemotherapy and radiotherapy can damage gonads, affecting fertility and potentially leading to premature menopause in women, while preserving testosterone production in men.
Area of Science:
- Reproductive medicine
- Oncology
- Endocrinology
Context:
- Cancer therapies, including high-dose cytotoxic drugs and radiotherapy targeting the whole body, pelvic region, or head, pose a risk of gonadal damage.
- Cancer treatments significantly impact male and female reproductive systems, with distinct effects on sperm and oocyte production.
Purpose:
- To outline the risks of gonadal damage associated with cancer treatments.
- To describe the specific effects of cancer therapies on male and female reproductive cells and function.
Summary:
- Cytotoxic drugs and radiotherapy can harm sperm production in men, though testosterone levels are often maintained.
- In women, these treatments accelerate primordial follicle loss, inhibit ovarian follicle development, and cause fibrosis, reducing the oocyte pool.
- While some young women may achieve pregnancy post-treatment, they face an elevated risk of early menopause.
Impact:
- Understanding these risks is crucial for fertility preservation strategies in cancer patients.
- This knowledge aids in managing long-term reproductive health and endocrine function after cancer therapy.
- Informs counseling for patients regarding potential fertility loss and menopause onset.

Cancer Therapies
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...

Cancer-Critical Genes II: Tumor Suppressor Genes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...
