Skin cells from infertile men transformed into early-stage sperm
Skin tissue from infertile men has been converted into sperm cell precursors after their stem cells were transplanted into mice...
One of two chromosomes that determine biological sex. Human males have an X and Y chromosome, whereas females have two X chromosomes.

The human Y chromosome may have some use, after all. Experts previously thought that the chromosome containing 'male' genes was shrinking to the point of extinction...
Male mice are able to reproduce healthy offspring with only two Y-chromosome genes, researchers at the University of Hawaii have discovered...

The 'female' X chromosome has been shown to contain several genes that may be involved in sperm production...
A US team of researchers has shown it is possible to link whole genome sequence data to a specific person, using only publicly available information....
How are we different from animals? Comedian Marcus Brigstocke met evolutionary geneticist Professor Mark Thomas at the Cheltenham Science Festival, and asked him about what makes humans so human. Their marvellously informative discussion of human achievement covered art, religion, Adam and Eve, and how they all tie into our genes....
Men may not be on the brink of extinction after all, according to a study on the evolution of the human Y chromosome. Previous research has suggested that the Y sex chromosome, carried only by men, is decaying genetically at such a rate that men would become extinct in five million years' time...

A sixth of men have a genetic variant which could increase their risk of heart disease by up to 56 percent, according to a recent study...
'Me, My Sex and I' is a documentary about people who are born neither entirely male nor female. I must state at the outset that this programme is about the sex of the individual, and should not be confused with gender, which is how people identify themselves (something that many other TV reviews have got wrong in describing this programme). As the show makes clear, sex is not an 'either or' for many people; the real buzz word here is 'ambiguous'....
Genetic differences between men and women could mean that women are better at resisting certain infections and diseases than men, a new study suggests. The second X chromosome in women gives them an immunological advantage over men, possibly giving credence to man's perceived susceptibility to 'man-flu'....
