Butter will keep for a long time refrigerated. Up to 6 weeks. You can also freeze this product and it will keep for over a year.   Hi - I only accessed this question as I hâ¦ave just tried some butter I had in the fridge. It is now Sunday 14th June 2009.
Sperm can be stored inside the male body for approximately 3 weeks after they've matured, after which they die inside the body if not ejaculated. So the entire sperm life cycle inside a man's body if not ejaculated (10 week maturation time + 3 week storage lifespan) is approximately 13 weeks or about 3 months.

Healthy sperm will not be ready to fertilize an egg until a new set of sperm â developed in healthy conditions â matures.
