Millions of couples struggling to have children, and a common cause of infertility mostly afflict women; for example egg quality is not good, uterine disorders, and age. However, approximately 20 percent of documented cases is 'sole male factor,' such as sperm in low numbers, abnormal shaped, or sluggish.

This is the 'Spermbot,' a magnetically controlled tiny motor like a corkscrew threaded to help propel lethargic sperms toward the target. Spermbot circling at the sperm tails, then pushed toward-and ideally into the eggs. (This happens in the privacy of medical clinics, instead of bedrooms.)
In the future, this tiny motor developed by the German scientists team can play an important role in artificial insemination. So far, the spermbot only tested on sperm and egg cells of cattle (as in the picture) and have not managed to achieve fertilization.
"The concept is interesting. But I admit I still skeptical," said Robin Fogle, an reproductive endocrinology expert and researcher at the Atlanta Center for Reproductive Medicine.
