What is it about?

In katoikogenic scorpions, blind outpocketings of the female gonads termed diverticula are structures in which individual oocyte grow, become fertilized, and finally embryos develop. We have shown for the first time that the lumen of the diverticula forms to open the route for sperm cells before fertilization due to fragmentation of apical parts of the stalk cells that occupy the central part of diverticula.

Why is it important?

Our findings show which way, in two katoikogenic scorpions, the sperm cells reach the oocytes waiting to be fertilized in the diverticula.


This article is devoted to fertilization in scorpions, one of the fundamental processes of developmental biology. I hope this article provokes to find out more about reproduction in chelicerates.
