The major causes for this are the quality of the ejaculate and the frequency of intercourse. For some men, advancing age is associated with declining testosterone levels, decreased sexual interest, and reduced sexual activity. Sperm motility can also decline with age. However, men continually produce sperm, so the decline in fertility in men isn't as pronounced as it is in women.
