Researchers generate rudimentary sperm using mouse stem cells which was then used to fertilize eggs and produce healthy mouse pups.
Sperm Analysis Could Help Involuntarily Childless Couples
In couples where the man had many chromosomal breaks, their best chance of becoming pregnant was to use ICSI (intracytoplasmic sperm injection) rather than IVF.

‘Immature sperm grown from embryonic mouse stem cells fertilizes with eggs to produce offspring. This technique may help infertile men in future.’
Scientists first isolated embryonic mouse stem cells and created primordial germ cells (PGC), a precursor to sperm and eggs. Then testicular tissue from newborn mice and other molecules were added to these primordial germ cells. After a period of 14 days, they developed into spermatids, non-motile sperms through meiosis. These spermatids were fertilized with eggs to produce nine baby mice. Dr.Jiahao Sha, who co-led the research, said, "If proven to be safe and effective in humans, our platform could potentially generate fully functional sperm for artificial insemination or in-vitro fertilization techniques. Because currently available treatments do not work for many couples, we hope that our approach could substantially improve success rates for male infertility."

How About a Sperm Quantity and Quality Test at Home?
Men turn to home testing kits to spare the embarrassment of attending a fertility clinic. However until now home kits only tested sperm count and not quality.

Children Conceived Through Artificial Techniques May Have Shorter Lifespan: Dr.Pascal Gagneux
Dr. Pascal Gagneux stated that assisted reproduction is an ‘evolutionary experiment’ that could prove as big a health disaster in the long haul.
