Cancer treatments like chemotherapy and radiotherapy can cause infertility in young patients. Protecting fertility through counseling and cryopreservation before treatment is crucial for cancer survivors.

Area of Science:

  • Oncology
  • Reproductive Medicine
  • Medical Research

Background:

  • Cancer survival rates have improved, leading to concerns about long-term side effects like infertility in young patients.
  • Chemotherapy (CT) and radiotherapy (RT) are common cancer treatments that can significantly impact testicular function and fertility.
  • Understanding the specific effects of different cancer therapies on male reproductive health is essential for patient care.

Purpose of the Study:

  • To review the current scientific knowledge on the impact of chemotherapy and radiotherapy on testicular function in young cancer patients.
  • To consolidate information regarding the risks of infertility associated with treatments for testicular and hematological neoplasms.
  • To highlight the importance of fertility preservation strategies in oncology.

Main Methods:

  • Systematic review of existing literature on chemotherapy and radiotherapy effects on male reproductive organs.
  • Analysis of data concerning specific treatment regimens, dosages, and their impact on sperm production and Leydig cells.
  • Examination of emerging research on spermatogonial stem cell survival and potential for future fertility restoration.

Main Results:

  • Cisplatin-based chemotherapy for testicular cancer can cause temporary azoospermia, with permanent damage possible at high doses (400-600 mg/m²).
  • Alkylating agents used for hematological neoplasms pose a severe risk of irreversible germinal epithelium damage.
  • Radiotherapy doses above 6 Gy can damage spermatozoa, while doses exceeding 15 Gy can harm Leydig cells.

Conclusions:

  • Fertility preservation counseling is mandatory for young cancer patients before commencing CT or RT.
  • Cryopreservation of sperm or testicular tissue offers the best option for protecting fertility in oncological patients.
  • Further research into spermatogonial stem cell recovery may offer future fertility restoration possibilities for cancer survivors.
