‘Kiss’ hormone injections could restore fertility

A HORMONE made by a gene called “kiss” has the potential to restore fertility in some women, scientists have found.

Twice weekly injections of the natural drug lead to long-term increases in levels of sex hormones that control the menstrual cycle, a study showed.

Kiss-1 plays a key role in regulating reproduction. It produces the hormone kisspeptin which helps humans and other animals go through puberty and become sexually mature.
