Researchers have developed a new use for Renishaw’s Raman spectroscopy solutions in assessing the healthiness of sperm cells.
The inability to have children creates great heartache for many couples. The most common cause is male infertility, usually characterised by sperm cells with low mobility in which genetic material (DNA) is often damaged. Unfortunately, DNA damage in [...]

Scientists at Leeds and Bradford have discovered a unique ‘DNA signature’ in human sperm, which may act as a key that unlocks an egg’s fertility and triggers new life.
Drs David Miller and David Iles from the University of Leeds, in collaboration with Dr Martin Brinkworth at the University of Bradford, have found that sperm writes [...]

University of Queensland research has revealed the older a dad is the more likely his children will have reduced cognitive abilities.

Research from the University of Pittsburgh published in the Nov. 20 edition of Heredity could finally provide evidence of the first stages of the evolution of separate sexes, a theory that holds that males and females developed from hermaphroditic ancestors.
