Sperm from female stem cells

   22.04.2019  2 Comments

Scientists have come a step closer to mimicking the natural process by which the body creates sperm from stem cells in work that could ultimately provide new treatments for infertility. The team is thought to be the first to have reached the halfway point on the developmental path from human stem cells to immature sperm. The study hints that one day it may be possible to manufacture sperm and eggs from stem cells or even adult skin cells. Previously, scientists have used stem cells to create viable mouse sperm , that were then used to produce healthy pups. Other teams have also injected immature human germ cells into the testicles of mice to produce cells that superficially looked like sperm, but which did not have the ability to fertilise eggs. There are particular safety concerns around the use of artificially created sperm and eggs, because any genetic flaws would be potentially passed on to all future generations. During the first few weeks, cells destined to become sperm and eggs follow the same route, with the trajectories diverging at around eight weeks.

Azoospermia, the absence of any sperm cells from the ejaculated semen, poses a real challenge to the fertility urologist. While there are options to create happy families for azoospermic couples, such as the use of donor sperm and adoption, most couples still want to have genetically related offspring. Advances in urology, gynecology, and fertility laboratory technologies allow surgical sperm retrieval in azoospermic men and achievement of live births for many, but not all azoospermic couples.
