Does sperm die when it comes in contact with air?

Air itself isn't the problem... it's the fact that sperm, you know, DRIES OUT, if it's left on your sheets instead of inside you.

To put it simply, any contact of semen or pre-ejaculate on or near the vaginal opening can result in pregnancy.

What happens to the sperms after vasectomy?\n\nAfter vasectomy sperms carry on being produced just as normal. They swim along the epididymis and up the vas to the site of the vasectomy blockage where they survive for some days then die off. The dead sperms are broken up and absorbed by the body’s white cells which enter the vas through the blood supply to this tube.

Sperm can get into the fallopian tubes within 5 minutes after ejaculation, but it can take up to an hour. But the first sperm usually cannot fertilize the egg. It takes sperm many hours inside the cervix, uterus, or fallopian tubes before it's ready to fertilize the egg, this is called capacitation. During capacitation, the outside of the sperm is prepared for entry into the egg.

There are theories in some religions that the production of a drop of sperm requires many drops of blood.  Some say 40, 80 or 100 drops.  There is no scientific basis for this.  Some people will claim it is a "scientific fact" but can't tell you where the research was done.

Supposedly yes to the mans sperm count because of the heat.  The sperm count is reduces.  But, my hubby takes the hottest baths you could imagine and we have 3 kids, must not be too bad.  =0)

Yes. You do understand how women get pregnant, don't you? It's about a sperm and an egg. That's all. It's not how you do it, when you do it, where you do it. It's just about a SINGLE, SOLITARY, swimming sperm cell that travels up the birth canal, past the cervix, and into the uterus, where it penetrates the outer cell wall of a SINGLE, SOLITARY egg. It doesn't matter HOW it gets there. And there are millions upon millions of sperm cells in every ejaculation.

It can. Even before you ejaculate, sperm are traveling up the tube and some will get mixed in with the precum (which works as a lubricant.) If you are unlucky enough, it could cause pregnancy.

i guess by technical defiition, no. Sperm are incapable of becoming humans without an egg.\n\nSo it is no more genocide than dandruff is suicide.

the sperm is white becuase of seminal fluid, and if you mean diffusions as ejaculation then more sperms will try to fertillise the egg

Pregnancy can now be detected 72 hours after fertilisation, but sperm can live for 3 days before attaching itself to the egg, so in answer, no. You can tell up to 6 days after. Hope this helps.

Well, if you use the laptop in the tub there could be a problem. It is hard for men to conceive once they're dead...

if there is mosture the sperm and egg can combie but if it can't float is water in produees asexualy

It all depends on if they are still producing viable sperm.  In order to know for sure they would have to be tested by there doctor.  There is an at home test kit available, but it has been deemed inaccurate so he should see his doctor.

Wearing tighty whities is waht causes a low sperm count which is why boxers are recommended for men when a couple is trying to conceive.  So, if you feel comfortable flapping in the breeze, enjoy!  Your sperm is safe.

Um, suppository, you mean. Well, there's a good chance the guy you'd have sex with could be allergic to the spermicide (a weirdly good chance, it is sperm-poison, after all, and any poison's got a lot of side effects), and it'd just ruin the whole flow and feel and gorgeousness of things. The best thing when it comes to safe sex and avoiding pregnancy is to use a condom, enough lubricant, and get no sperm/precum anywhere around the, uh, v-thing. heh. water-based lube sort of makes sure the condom can't break easily by reducing friction.\n\nwhich means, lesser chance of ejaculate leaking out, lesser chances of getting pregnant.

Well, my dad got balls the size of grapefruit.\n\nHe just had to fall off a catwalk above the ship's engine room and land astraddle a steam pipe to do it.\n\nThey went down later, though.  \n\nAND after that he fathered 7 kids, so it didn't do as much harm as his wild screams at the time might have suggested.\n\nMen's testes vary in apparent size due to two conditions.  One is temperature.  If you're in a cold place - such as swimming in a lukewarm pool - your testicles "ascend" or rise up into your groin.  If you are physcially over heated - after running a long away, for example - your testes will "descend."  This is to protect the sperm inside so that they are viable.  Extreme temperatures affect that.  (I knew a guy who used to take a plunge in a freezing pool hoping it would kills his sperm so he didn't have more kids; birth control in his life was NOT an option.)\n\nThe other reason is age.  men's testes hang differently over the years.\n\nJust accept yourself and remember it isn't the size, it's the skill!  Your question suggests you are perhaps a bit too young to worry about this anyhow.
