Generating sperm from 23 years old frozen stem cells

Testicular cryopreservation is an experimental method used to preserve gonadal tissue of pre-pubertal boys or men whose fertility is likely to be compromised due to chemotherapy treatment. A recent study on rats shows that viable sperm can be produced from cryopreserved spermatogonial stem cells (SSC) after 23 years of storage – a discovery that offers …

Building functional sperm

Many thousands of genes are required for male fertility in mammals. In the testis, these genes govern the diverse individual processes of mitosis, meiosis and spermiogenesis, which are ultimately required to generate sperm. During this latter process of spermiogenesis, round spermatids undergo a complete remodelling to generate a sperm tail for motility, sculpt the nucleus …

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 …

COST Action ANDRONET

ANDRONET, the biggest running European network in andrology, aims to increase research collaboration, education, and public awareness in male reproductive health. It was born within a social context of worst reproductive outcomes, tightly related with the male factor, in which establishing strong connections between clinicians and researchers is essential to tackle a problem with such …

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 …
