You produce sperm every day, but a full sperm regeneration cycle (spermatogenesis) takes about 64 days. Spermatogenesis is the complete cycle of sperm production and maturation. It constantly supplies your body with sperm able to travel through the vagina to an unfertilized ovum in a woman's ovaries to conceive. This makes complete sense as I 100% go through gainning cycles when I want to gain.
