Abstract:
Improved therapies for cancer and other conditions have resulted in a growing population of long-term survivors. Infertility is an unfortunate side effect of some cancer therapies that impacts the quality of life of survivors who are in their reproductive or prereproductive years. Some of these patients have the opportunity to preserve their fertility using standard technologies that include sperm, egg, or embryo banking, followed by IVF and/or ET. However, these options are not available to all patients, especially the prepubertal patients who are not yet producing mature gametes. For these patients, there are several stem cell technologies in the research pipeline that may give rise to new fertility options and allow infertile patients to have their own biological children. We will review the role of stem cells in normal spermatogenesis as well as experimental stem cell-based techniques that may have potential to generate or regenerate spermatogenesis and sperm. We will present these technologies in the context of the fertility preservation paradigm, but we anticipate that they will have broad implications for the assisted reproduction field.
Insights
New stem cell technologies offer fertility preservation options for cancer survivors, particularly prepubertal patients. These advancements aim to enable biological parenthood for individuals unable to use standard fertility banking methods.
Area of Science:
- Reproductive Medicine
- Oncology
- Stem Cell Biology
Background:
- Cancer therapies can cause infertility, affecting survivors' quality of life.
- Standard fertility preservation (sperm, egg, embryo banking) is unavailable for prepubertal patients.
- There is a need for novel fertility solutions for young cancer patients.
Purpose of the Study:
- To review the role of stem cells in spermatogenesis.
- To explore experimental stem cell-based techniques for generating sperm.
- To discuss the potential of these technologies in fertility preservation and assisted reproduction.
Main Methods:
- Review of current literature on stem cells and spermatogenesis.
- Analysis of experimental stem cell-based fertility technologies.
- Contextualization within the fertility preservation paradigm.
Main Results:
- Stem cells play a crucial role in normal sperm production (spermatogenesis).
- Experimental techniques show promise for generating or regenerating spermatogenesis and sperm.
- These stem cell approaches could offer new fertility options for previously untreatable patients.
Conclusions:
- Stem cell technologies represent a promising frontier for fertility preservation in cancer survivors.
- These innovations may extend to broader applications within assisted reproduction.
- Future research could enable infertile patients to have their own biological children.

The process of spermatogenesis can be divided into mitosis, meiosis, and spermiogenesis. During mitosis, the spermatogonia or stem cells divide to produce two identical daughter cells, type A and B spermatogonia. Type-A...
