Can a Man Be Too Old to Have a Baby?
No, a man cannot be "too old" to conceive in the way a woman can, but age does matter. Sperm is produced fresh on a roughly 70–90 day cycle, which means quality is not fixed. Even after a disappointing semen analysis, many men in their 40s and beyond can make meaningful improvements to count, motility, morphology and DNA integrity. Age raises certain risks, but it rarely closes the door.
