Namibian medical experts are advising men to consider starting a family earlier in life, as advanced paternal age can increase the risk of deformities in babies and miscarriages in women. According to Dr. Kalumbi Shangula, men's fertility depends on several key sperm metrics, with age being a primary determining factor. He emphasizes that the quality of sperm is crucial for producing a healthy baby.
Dr. Shangula explains that sperm quality declines from the age of 40, and that men's fertility is influenced by the number of motile sperms, sperm count, and overall health of the sperm. He notes that while women are often reminded of their 'biological clock', many men do not feel the same pressure when it comes to settling down and starting a family. In fact, many men in their 20s are not even considering having children.
Dr. Cornelia Ndifon echoes Dr. Shangula's views, stating that advanced paternal age affects outcomes, with the risk increasing progressively over time. She notes that a father's age can affect fertility and the baby's health, with effects usually commencing from about the age of 40. However, Ndifon emphasizes that not every older father will experience complications, and that some individuals may experience issues prior to turning 40.
According to Ndifon, advanced age alters the fundamental properties of sperm and its genetic composition, affecting sperm count, volume, and motility. She explains that it can also increase DNA damage and the tendency of genetic mutations. Ndifon notes that external environmental factors combined with age could potentially compound these genetic impacts.
Ndifon states that older paternal age can reduce the likelihood of conceiving and raise the risk of losing a pregnancy. She notes that there might be a reduced chance of falling pregnant in the first place, and that there might also be an increase in miscarriages.
Children born to older fathers face a higher risk of specific medical and neurodevelopmental conditions, including autism spectrum disorder, dwarfism, and schizophrenia. Ndifon emphasizes that these risks are not absolute and that not every child born to an older father will experience these conditions.
The medical experts' warnings highlight the importance of men considering their age when planning to start a family. While more research is needed to fully understand the effects of advanced paternal age, the current evidence suggests that men should be aware of the potential risks and take steps to minimize them.
