Preserving Fertility for Men with Cancer: Options and Overcoming Barriers
By: Mark Perloe
For men facing cancer treatment, the risk of infertility is a major concern that is often overlooked. While fertility preservation options exist, studies consistently show that a significant proportion of patients are not adequately informed or offered these choices by their healthcare providers before undergoing potentially sterilizing cancer treatments.
The main barriers to men being aware of fertility preservation include limited knowledge and training among providers, discomfort discussing the sensitive topic, low referral rates to reproductive specialists, logistical challenges, time constraints before treatment initiation, perceptions about appropriateness based on prognosis, and patient-related factors like lack of awareness and financial concerns.
It is crucial for men to understand their options for preserving fertility, which include:
Sperm Cryopreservation (Sperm Banking)
This standard and most effective method involves collecting and freezing sperm samples before treatment for future use through assisted reproductive techniques like intrauterine insemination (IUI) or in vitro fertilization (IVF) with intracytoplasmic sperm injection (ICSI). It is well-established and successful for post-pubertal males.
Testicular Tissue Cryopreservation
An experimental approach where testicular tissue is removed and frozen before cancer treatment. The frozen tissue may potentially be used later to extract sperm stem cells for reimplantation or to induce in vitro spermatogenesis. However, no live births from this method have been reported in humans yet.
Gonadal Shielding
Protecting the testicles from radiation damage by using lead shields during radiotherapy. Its effectiveness is limited by patient anatomy and radiation field requirements.
Sperm Retrieval
For males who cannot produce a semen sample, sperm can be surgically retrieved from the testicles or epididymis through techniques like testicular sperm extraction (TESE) or percutaneous epididymal sperm aspiration (PESA). Retrieved sperm can then be used for IVF/ICSI. This invasive option is appropriate when a male cannot produce a semen sample due to conditions like anejaculation, obstructive azoospermia, or prior to puberty.
While sperm cryopreservation is the most established and successful fertility preservation method, sperm retrieval combined with IVF/ICSI can be an option when cryopreserved sperm is unavailable or inadequate. However, IVF/ICSI is more invasive, costly, and has lower success rates compared to using cryopreserved sperm for insemination.
Overcoming barriers to awareness and utilization of fertility preservation options requires improved education and adherence to clinical guidelines from organizations like the American Society of Clinical Oncology (ASCO) and the American Society for Reproductive Medicine (ASRM). Establishing formal fertility preservation programs with multidisciplinary teams, patient navigators, and educational initiatives can help ensure that men with cancer have the opportunity to make informed decisions about preserving their fertility before undergoing cancer treatments.
