Cancer Patients

Nowadays, cancer treatments bring along considerable increase of expectation and quality of life. Due to that, in most cases, patients take back their lives and continue to dream and make plans for the future. However, this treatments, including chemotherapy and radiotherapy, still have harmful effects on both man`s and woman`s  reproductive system, with the risk of causing transitory or permanent infertility. For this reason, there is a increasingly preoccupation about getting aware of fertility preservation before the beginning of cancer treatments. The gamete freezing is done, preferentially before the patient is exposed to the treatment. There are particularities for each case, but in general, we can divide the steps in the following way:



Adult Male

  • Semen freezing, in several lots, to be used in the future in intrauterine insemination or in vitro fertilization. After the recovery of the cancer treatment, the patient has to realize an exam to test if the production and quality of sperm is compromised and evaluate if it is necessary to keep the semen stored or not.

Adult Female

  • Egg Freezing– the eggs are collected after ovarian stimulation with drugs.
  • Embryo Freezing – in case the woman is already married. The embryos can be unfrozen and transferred to the patient`s uterus after the cancer treatment, when the couple is ready.
  • Ovarian Tissue Freezing.


  • There is still no alternative for this group of patients. Though, if their fertility is compromised when they become older, it is possible to obtain a minimal quantity of semen from the testicles to realize in vitro fertilization with ICSI.
