London, May 24: To improve the fertility problem, scientists have developed a new technique to examine human sperm without damaging them.
The Magnetic Resonance Spectroscopy technique uses powerful magnets and works like a scanner to listen the echoed signal by the molecules in response.
It helps to distinguish between populations of good or poor sperm, discovered by physicists from the University of Sheffield in Britain .
It is a safe method as low energy pulses do not damage sperm. It can be used in IVF treatment as well.
“The technique of Magnetic Resonance Spectroscopy has been previously used to examine the molecular composition of many cells and tissues in other diseases such as cancer, but it has never previously been used to examine live sperm. As such, these results are a world first,” said Professor Martyn Paley.
The scientists gathered fresh sperm samples from healthy volunteers and patients, the result helps to create a difference between samples, according to the study published in the journal Molecular Human Reproduction.
“Most of the advanced techniques we have available to examine the molecules in sperm end up destroying them in the process by either adding stains or by breaking open their membranes to look at the contents,” Professor Allan Pacey said.
“To potentially have a technique which can examine the molecular structure of sperm without damaging them is really exciting,” Pacey added.
