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.
This change in the fluid allows the ejaculated sperm to stay in the vagina initially, but then swim out as the seminal fluid becomes more liquid. These enzymes quickly destroy any sperm that canât swim out of the semen within a few hours. It takes approximately 72 days for sperm to mature in the body.During the last 14 days of this process, the sperm are very much alive and swimming. They are alive a long time prior to leaving a manâs body. During freezing, sperm are cooled to a very low sub zero temperature (minus 196 degrees Centigrade).his change in the fluid allows the ejaculated sperm to stay in the vagina initially, but then swim out as the seminal fluid becomes more liquid.
