Human immature testicular tissue organ culture: a step towards fertility preservation and restoration by Nagham Younis et al. in 2023.
The Source Article's Abstract
Background
Cryopreservation of immature testicular tissue (ITT) is currently the only option to preserve fertility of prepubertal patients. Autologous transplantation of ITT may not be safe or appropriate for all patients. Therefore, methods to mature ITT ex vivo are needed.
Objectives
Aim to investigate the feasibility of inducing in vitro spermatogenesis from ITT cryopreserved for pediatric patients prior to initiation of gonadotoxic therapy.
Materials and methods
Cryopreserved-thawed ITT from prepubertal and peripubertal patients were cultured for 7, 16, and 32 days in medium with no hormones or supplemented with 5 IU/L FSH, 1 IU/L hCG, or 5IU/L FSH+1 IU/L hCG. Samples were evaluated histologically to assess tissue integrity, and immunofluorescence staining was performed to identify VASA (DDX4)+ germ cells, UCHL1+ spermatogonia, SYCP3+ spermatocytes, CREM+ spermatids, SOX9+ Sertoli cells.

The Promise of In Vitro Spermatogenesis
Until now, cryopreservation of immature testicular tissue (ITT) was the only option for preserving the fertility of prepubertal patients. This study aims to change that by investigating the feasibility of inducing in vitro spermatogenesis.
The research team used cryopreserved-thawed ITT from prepubertal and peripubertal patients, cultured them in various hormonal environments, and evaluated the tissue integrity and cellular markers.
Implications for the Medical Profession
- Offers new avenues for fertility preservation
- May reduce the need for autologous transplantation
- Opens up possibilities for safer fertility restoration methods
FAQs: What You Need to Know
Is this method safe for all patients? The study suggests that autologous transplantation may not be safe or appropriate for all, making this method a promising alternative.
How effective is this new method? While complete spermatogenesis was not observed, the study shows promise in the initial stages of germ cell development.
