Sperm has classically been perceived as a vehicle of the male genome to the zygote. However, thanks to the application of high-throughput technologies to study the male gamete, it is now known that this small cell is much more complex than a simple DNA carrier. The sperm cell contains, besides the paternal genome, a great …
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 …
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 …
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 …
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 …
We are delighted to invite you to join us in the 14th NYRA Meeting taking place on September 19th-21st 2022, at University of East Anglia in Norwich in the United Kingdom. This last year has been a challenging time. The coronavirus pandemic has caused severe disruptions and obstacles to research as well as affected all …
By MANON OUD Approximately 1% of all men fail to produce sperm at all. In a recent publication in the New England Journal of Medicine, Nagirnaja and Mørup et al. demonstrate one of the causes for such complete lack of sperm production, which is called non-obstructive azoospermia. The results point to a direct mechanistic effect …
The European Academy of Andrology (EAA) is pleased to announce the 3rd edition of the EAA Zagreb Summer School on Testis Histology and Pathology for Clinical Andrologists and Embryologists to be held in Zagreb, Croatia from June 27th to July 1st, 2022 To apply, the candidates should fill out the Application Form and send it together with a …
It is with great sadness that we learned about the passing of Professor Bernard Jegou from Rennes, France. Bernard Jegou was a well-known person in the field of Andrology, especially for his winning personality that many of us have experienced during the Testis Workshops over the years, but also for his outstanding scientific career. Bernard …
