Neonatal testis growthrecreated in vitro by two-dimensionalorgan-spreading

Since the beginning of the 20th century, attempts have been made to differentiate male germ cells into mature spermatozoa in culture [1]. In human, in vitro maturation of meiotic spermatocytes and later developmental stages was demonstrated in the early 2000s [2]. However, production of functional spermatozoa from spermatogonial stem cells has not been established yet.…

Report on the 11th meeting of the Network for Young Researchers in Andrology (NYRA)

This year’s NYRA meeting, 22nd-23rd of May, was held adjacent to the 20th European Testis Workshop in Lisbon, Portugal. The audience included Master students, PhD students, postdoctoral researchers and even a few group leaders. In total, our two-day seminar series was attended by 30 participants representing 10 different countries: Belgium, Denmark, Finland, France, Germany, India,…

Accuracy of human sperm DNA oxidation quantification and threshold determination using an 8-OHdG immuno-detection assay

Accuracy of human sperm DNA oxidation quantification and threshold determination using an 8-OHdG immuno-detection assay Vorilhon S et al. – Hum Reprod. 2018 Apr 1;33(4):553-562. doi: 10.1093/humrep/dey038 Of factors contributing to sperm DNA damage, oxidative stress is recognized as one of the major contributing causes to sperm cell dysfunction. Caused by elevated levels of intracellular…

First time in vitro maturation of oocytes from human primordial follicles

Currently, couples going through In vitro fertilisation (IVF) require the treatment of women with hormones for ovarian stimulation in order to stimulate simultaneously growth of several follicles and to maximize a large number of oocytes available IVF. However, this treatment can have several side-effects and it is not suitable for every woman. This is especially…

Environmental levels of triclosan and male fertility

Press Highlights Triclosan (2,4,4’-tricloro-2’-hydroxy-diphenyl ether) is a synthetic compound classified both as a drug and a pesticide. It is widely used in consumer goods for its broad-spectrum antimicrobial properties. At low doses, triclosan impairs bacterial growth by inhibiting enoyl-acyl carrier protein reductase, an enzyme necessary for bacterial lipid biosynthesis, while at high doses, triclosan is…
