For patients who had testicular tissue cryopreserved before receiving gonadotoxic therapies, transplantation of testicular tissues and cells has been recommended as a potential therapeutic option. There are no studies that indicate the generation of sperm after human immature testicular tissue (ITT) or spermatogonial stem cells (SSCs) transplantation. The use of releasing scaffolds and localized drug delivery systems as well as the optimizing transplantation site can play an effective role in increasing the efficiency and improving the quality of testicular tissue and cell transplantation in animal models. Current research is focused on optimizing ITT and cell transplantation, the use of releasing scaffolds, and the selection of the right transplantation site that might restore sperm production or male infertility treatment. By searching the PubMed and Google Scholar databases, original and review papers were collected. Search terms were relevant for SSCs and tissue transplantation. In this review, we'll focus on the potential advantages of using scaffolds and choosing the right transplantation site to improve transplantation outcomes.

Background: Male infertility (MI) is a polygenic condition mainly induced by spermatogenic failure/arrest or systemic disease with a large clinical spectrum. Lately, genetic sequencing allowed the identification of several variants implicated in both aforesaid situations.
Methods And Results: In this case study, we performed whole exome sequencing (WES) on the genomic DNA of a 37-year-old Moroccan man with Non-Obstructive Azoospermia.

Introduction: Cryptorchidism can damage cells in the cryptorchid testes due to elevated local temperatures, potentially impacting the fertility of the child in adulthood. Research indicates that vitamin D enhances sperm quality in adult males. This study aimed to explore whether vitamin D inhibits NLRP3 activation, thus helping to mitigate heat stress damage to testicular spermatogenic and Sertoli cells.

Aging is characterized by cellular degeneration and impaired physiological functions, leading to a decline in male sexual desire and reproductive capacity. Oxidative stress (OS) lead to testicular aging by impairing the male reproductive system, but the potential mechanisms remain unclear. In the present study, the functional status of testicular tissues from young and aged boars was compared, and the transcriptional responses of Leydig cells (LCs) to hydrogen peroxide (HO)-induced senescence were explored, revealing the role of OS in promoting aging of the male reproductive system.

All patients where the cancer treatment has gonadotoxic potential should be referred for oncofertility advice. The effect of chemotherapy and radiotherapy on the human ovary can vary from no impact to full-blown premature ovarian failure due to hormonal and follicular depletion. Total contraindications to fertility cryopreservation include acute malignancy that requires immediate lifesaving therapy.

Methods to quantify germ cell number in human immature testicular tissues are essential to evaluate the impact of chemotherapy exposures and for optimising cryopreservation protocols used in fertility preservation for prepubertal boys. Established quantification methods rely on the presence of round tubules within the tissue. However, round tubular cross sections are limited in human prepubertal testicular tissues, especially when using in vitro culture.
