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.
Hope that helps. Sperm is made in the testicles. The testicles only hold sperm. The vas deferens and the prostate gland secrete semen (the liquid portion of ejaculation) and when sperm are released they mix with the semen and both are secreted during ejaculation.
