A group of researchers from the Stanford University has for the first time ever sequenced genomes of several sperm cells and that too individually. The report says that recombination would be easier to study with the sequencing.
A man in his 40s had donated his sperms, 91 in number, genomes of all of which were thoroughly mapped by the team. Published in the Cell journal, the study has paved a clear way to determine the reason what errors in a particular process causes a person to face problems in conceiving.
Prof. Stephen Quake, lead author, and his colleagues have told that a baby tends to inherit his parents’ as well as grandparents’ traits and elements via a natural process i. e. recombination. And the same is highly essential for a full development of new genetic codes in them.
Lacking the same or a problem in the process may lead the sperm to develop incomplete genetic codes, ultimately causing infertility. It has been affirmed that sometimes even entire chromosomes are missed. Studying the genomes would help solve such issues.
"People have difficulty conceiving children due to reproductive disorders, and this will provide a very effective way to analyze when there are problems with their sperm", said Prof. Stephen.
