There is an expiry date on women's fertility; the majority of women experience menopause at 45–55 years of age, marking the decline of their natural fertility. Sperm production goes on until older age, though sperm quality and quantity slowly start to deteriorate. Based on research, male fertility declines after the age of 40. Smoking, excessive drinking, and steroids, which all affect sperm quality, should be avoided. Although they do not have an immediate "expiry date" like menopause, with age, the quality of the sperm, fertility rate, and well-being of the child are affected.World IVF Day and other awareness platforms educate couples that fertility is a two-way responsibility.
