Ok, yes this is really happening – tiny motors that attach to sperm to help improve how well they swim (motility), and experts are saying that this might soon become a feasible treatment for male factor infertility.
For the millions of American couples that struggle each year to conceive a child, most procedures, such as in vitro fertilization and artificial insemination, have a relatively low success rate. Male fertility issues contribute to about half of the cases of infertility. One major cause is low sperm motility, or the sperm’s inability to swim to the egg. Now a team of German researchers has invented a “spermbot” that can help sperm swim better to improve couples’ fertility, according to a study published recently in the journal Nano Letters. Ideally, this technique would also be less costly than other assisted reproductive technologies, which can cost thousands of dollars per round.
