    As far as I know :

    It can tuf a few hours outside the human body if kept at the right temperature etc.

    The only way to kill sperm is to hit them with a huge hammer and squish them all.

    Seriously though sperm can live outside the body almost as long as it can inside the body. Unless you wash your hands you pretty much wont get rid of it.

    I heard sperm is full of protein and Vit E so some women slap it on their faces as a nutrional face mask ... but probably in the privacy of their own home!

    yeah sperm can live outside in air for ages... i seem to remember being told that in sex education:P.
    i think the likelihood of gettin pregnant by just puttin it in urself is pretty low tho cos the sperm dont get the propulsion. but it can still happen n no point riskin it <IMG alt="image" SRC="http://www.thesite.org/ubb/smile.gif"&gt;

    I'm sorry, this isn't very specific, but it's all I could find <IMG alt="image" SRC="http://www.thesite.org/ubb/frown.gif"&gt;

    How long do sperm live outside of the body? Can sperm live in water?
    27th April 1999


    Living sperm (spermatozoa) - like other cells - require suitable conditions for survival outside the body. The chemical make-up of the fluid medium in which they are suspended and the temperature at which it is maintained are two key variables. The technique of in vitro fertilisation (IVF) requires that sperm are kept in optimal condition for variable amounts of time before they are placed in contact with eggs for fertilisation. This can be done either by freezing and then re-thawing when required, or by incubation at normal body temperature for up to several hours in a suitable fluid medium (Liu, Clarke, and Baker, 1986). The fluid has to be isotonic for the sperm and contain nutrients and other materials for the sperms’ survival. One of the difficulties in keeping sperm alive in a culture dish is that they produce oxygen free radicals. These are highly reactive molecules which at lower levels are thought to control normal sperm function, but which can become damaging at higher levels (Aitken, 1995; Gomez and Aitken, 1996).

    Sperm would not survive for long in plain water - although the seminal fluid would provide some protection initially, the water is very hypotonic to the sperm cells and would soon cause them to swell and disintegrate.

    I had a life once, but I stopped feeding it so one day it just walked away.
