Japanese researchers solve common form of male infertility

posted on January 14, 2016

Researchers have found a solution for a common form of male infertility.

Nonobstructive azoospermia is a condition in which sperm do not grow to maturity.
Japanese researchers have now reported a way to extract immature sperm from the testicle and use it for in vitro fertilization. They are using it successfully at a clinic in Kitakyushu.

The team was headed by Atsushi Tanaka, founder of the clinic, Saint Mother Hospital. The researchers say it resulted in 112 births between September 2011 and December 2014.

The clinic is thought to be the first carrying out such treatment successfully.

The team found a way to identify round spermatids, sperm cells that have not matured. This is difficult.

“It took us about a decade to find a way to differentiate the cells, which was one of the main reasons why this treatment was unsuccessful,” said Tanaka, who specializes in both male and female infertility.
