Viable Offspring Derived From Single Unfertilized Mammalian Oocytes

The general understanding of fertilization is the fusion of two haploid gametes, the spermatozoon, and the oocyte, to form a diploid cell that goes through the multiple cell division and cell differentiation events of embryo development. However, recent research has pushed this understanding. Parthenogenesis, also known as virgin births, is another way of embryo development …

Single cell sequencing enables novel insights to unravel human testicular tissue heterogeneity

Testis tissue is very complex and heterogeneous as it is made up of several somatic (Leydig, Sertoli, peritubular myoid cells and others) and germ cell types (spermatogonia, spermatocytes and spermatids). Due to the high number of different cell types, histological and molecular studies have always been challenging. As an example, the use of bulk RNA …

World’s first approval for testicular re-implantation to restore fertility of childhood cancer survivors

Prof. Ellen Goossens from the Vrije Universiteit Brussel (VUB), in cooperation with the Universitair Ziekenhuis Brussel (UZ Brussel), received the ethical approval to re-implant previously frozen testicular tissue in male cancer survivors who lost their fertility because of childhood cancer treatments. If successful, sperm cells will develop in the implanted tissue to restorethe fertility ofthese patients. Childhood cancer survival rates …

Complete spermatogenesis in intratesticular testis tissue xenotransplants from immature non-human primate

Boys receiving gonadotoxic treatment (e.g. chemo- or radiotherapy) before puberty face the possibility of being infertile when they reach adulthood due to the loss of germ cells. As mature spermatozoa are not present, the only fertility preservation strategy currently offered involves the cryopreservation of immature testis tissue (ITT) containing spermatogonial stem cells (SSCs). Auto-transplantation of …
