Abstract
PURPOSE OF REVIEW: 
An
 increasing number of older men are seeking help for fathering a child, 
but male fertility gradually declines with age. This review highlights 
changes in male reproductive biology and practical clinical concerns for
 aging men.
RECENT FINDINGS: 
Aging may have an impact on 
sperm DNA damage such as single nucleotide polymorphisms. A recent 
landmark study identified that the number of single gene de-novo 
mutations in the offspring increased by two mutations per year based on 
paternal age. Additionally, advanced paternal age has been linked with 
neurocognitive disorders such as autism and schizophrenia. For the 
management of hypogonadism, strategies using selective estrogen 
modulators have been increasingly utilized to maintain fertility 
potential.
SUMMARY: 
Aging has an impact on male fertility potential, as well as potential genetic effects for the offspring.
