In the types of sexual reproduction known as anisogamy and its subtype oogamy , there is a marked difference in the size of the gametes with the smaller one being termed the "male" or sperm cell. A uniflagellar sperm cell that is motile is referred to as a spermatozoon , whereas a non-motile sperm cell is referred to as a spermatium. Sperm cells cannot divide and have a limited life span, but after fusion with egg cells during fertilization, a new organism begins developing, starting as a totipotent zygote.
The good news, there are some very tangible lifestyle changes that men can make to improve their sperm health and overall fertility.
You produce sperm every day, but a full sperm regeneration cycle spermatogenesis takes about 64 days.
