French researchers said Thursday they had
patented a method to create sperm using stem
cells harvested from infertile men — though they
do not know if the lab-fabricated seed actually
works.
The team hailed their technique as a step towards
solving male infertility, but admitted it would take
several years before the “quality” of the sperm
will be confirmed.
The method, patented in June, took 20 years to
refine, said the researchers from Kallistem
biotech company in Lyon, east France.
It involved recreating, outside the human body,
the fluid in which seminiferous tubules — the
tiny structures where sperm cells are formed in
the male testes — can survive.
They used it to coax rat, monkey and then human
sperm cells from spermatogonia, immature cells
that become eggs or sperm. The process is
complex, and takes about 72 hours.
The sperm are “morphologically normal” (normal-
looking), the researchers said. It is not known
whether the tiny cells are up to the job of
creating babies.
The next step, the team said, is to try and give
life to rats with rat sperm created using the
method.
“We must see if the baby rats are normal,
whether they are able to reproduce,” project
member Philippe Durand told journalists in Lyon.
Then there will be a battery of tests with the lab-
manufactured human sperm, to compare it to
ordinary sperm, and finally clinical trials.
The work has not yet been validated through
publication in a peer-reviewed science journal.
But the team said in a statement their work
“opens the way for therapeutic avenues that have
been eagerly awaited by clinicians for many
years.”
“From a testicular biopsy in these infertile men,
the scientists will be able to obtain spermatozoa
in vitro,” said the statement.
However, Nathalie Rives, an infertility expert
from Rouen in northern France, cautioned: “We
are not there yet”.
“Before this technique can find any practical
application, it must be proven to work with (cells)
from the testes of prepubescent boys and men
who have trouble generating sperm,” she told
AFP.
In August 2011, scientists in Kyoto said they had
successfully coaxed sperm cells from mouse
embryonic stem cells.

Invasion or no Invasion, they're discovering, inventing, launching, name it. That's why they look down on us TOO MUCH.

invent everything ☺
