At least 30% of identified infertility cases are caused by male fertility difficulties, and sperm counts have plummeted by 50% in the last four decades. Furthermore, individuals are having children later in life than ever before, and aging affects male fertility: every 8 months, a male-bodied person’s sperm has a new genetic mutation. Male fertility relies heavily on sperm. You won’t be able to have a healthy pregnancy without medical help unless you have at least some healthy sperm.
