Scientists One Step Closer To Male Birth Control Pill

New research at the University of Edinburgh has pinpointed a gene called Katnal 1 that manages the final stages of sperm development. In theory, the work could lead to a new drug that would block the gene.

“The important thing is that the effects of such a drug would be reversible because Katnal 1 only affects sperm cells in the later stages of development, so it would not hinder the early stages of sperm production and the overall ability to produce sperm,” a researcher tells the BBC. A professor also noted that the genetic research from the study could “shed light on why some men are sub-fertile and why their sperm does not work properly.”
