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.
