Delayed Fatherhood Associated With Greater Risk Of Genetic Anomaly In Offspring

Researchers have found the reason behind why elderly men are more prone to having kids with health issues as compared to younger fathers.

Scientists from the Oxford University and the Copenhagen Hospital found that elderly men were more prone to developing non-malignant testicular tumours known as spermocytic seminomas.

Though these altered cells are not of any harm to the men, the scientists consider that they could alter germ cells that produce sperms that could lead to genetic mutations in their offspring’s DNA leading to atypical growth disorders.

The study backed by the Wellcome Trust and the Danish Cancer Society could explicate the reason behind the prevalence of particular ailments among kids of older-aged fathers.

Genetic anomaliesHelming the study, Professor Andrew Wilkie of the University of Oxford stated that majority of the men developed these small clusters of mutant cells in their testicular area when they aged. These clusters are much alike moles noted on the skin’s surface that are generally benign on their own. However, their location in the testicular region could make the sperms –producing offspring to be born having a host of grave conditions.

The study printed in the Nature Genetics aids in elucidating the source of many grave conditions that have a major bearing on infancy and development.

These comprise of achondroplasia & Apert, Noonan & Costello syndromes, along with some other conditions that lead to stillbirths. The outcome of this research points to the crucial aspects that not just women, but even men need to carefully contemplate the risk factors associated with delaying parenthood.

The study would be beneficial to the doctors in clarifying to parents why the disorder has occurred and enlightening them that future offspring are not likely to be affected.

The outcome could also shed light on the prevalence of ailments inclusive of breast cancer, autism and schizophrenia; appear to be more recurrent among the children of older-aged fathers.

Professor Wilkie indicates that analogous yet milder alterations could be contributors to these ailments.

Professor Wilkie points out that their discovery till recent is merely the tip of a humongous iceberg of slightly damaging mutations being infused within our genome. Such alterations could be too mild and quite atypical to be spotted by presently available technology, but their massive numbers might have a snowballing effect, that could lead to ailments.
