Sperm can live up to 72 hours after ejaculation.
Yes, sperm can live in the ocean. This is because sperm thrives in warmer temperatures such as ocean water. However, sperm typically does not live outside the body for more than 20 minutes.
It all depends on the temperature at the time Sperm exposed to air, deposited on skin, clothing, bed linens, or toilet seats, for example, dry out very quickly and die, usually within minutes after ejaculation. A sperm sample collected in a sterile container at body temperature may remain alive for several hours, but the sperms' fertilizing capability drops dramatically within 60 minutes after ejaculation. Sperm deposited inside the vagina usually die within 20-30 minutes after ejaculation. Sperm that move from the vagina into the uterus can survive longer. Studies have shown that conception is possible up to five to six days after intercourse. So it is possible for some sperm to survive that long in the uterus, usually in the cervical mucus or the fallopian tubes. But that is not typical. Most sperm die in the uterus within 24-48 hours after ejaculation, and the more time has passed after ejaculation, the less likely is the fertilization of the egg. In excellent laboratory conditions and in a nutrient medium they can remain alive for up to seven days.
Absolutely not. Men ejaculate 300 to 400 million sperm in 1 ejaculation. Sperm can not live for more than a day outside of the male penis (testicles) and it does not live in the vaginal area any longer than 3 days. If a sperm fell onto the undergarments of a female you would not see it, nor would it live long enough for it to get someone pregnant.
It seems like your question might be incomplete or unclear. If you're referring to "sperm," a typical ejaculation contains about 1,500,000 to 5,000,000 sperm per milliliter, and an average ejaculation can release about 2 to 5 milliliters of semen. If you meant something else by "spem," please provide more context for a more accurate response.
The term for the dissolution of sperm is "liquefaction." This is a normal process that occurs shortly after ejaculation, where the gel-like consistency of semen changes to a more watery form to allow for easier movement of sperm.
If you mean on a genetic level, then yes. Dogs have far more crhomosomes than humans. If you mean it's physical properties, then yes as well. A dog's semen is different depending on when in the ejaculation the semen is sampled. In the beginning, the semen is more watery, towards the middle of the ejaculation phase, it turns more sticky and whitish, meaning it contains actual sperm, towards the end , again runnier and more transparent, but sticks more. The time a dog starts ejaculating til he finishes is somewhere beteen 10-30 minutes (!!) During that time nature has provided the base of the penis with a gland that will swell during orgasm so that it is kept inside your vagina. It makes it difficult if not impossible, depending on the dogs size to remove the knot. Hope this explains more. If you mean on a genetic level, then yes. Dogs have far more crhomosomes than humans.

Sperm whales can live to forty years or more.
During ejaculation, a man can release between 1.5 to 5 milliliters of semen, which can contain millions of sperm. However, only a small fraction of this sperm will actually reach the egg during fertilization.
Condoms are not 100%, more of the 80-90% range. And pre-ejaculation which can happen within seconds of stimulation has sperm in it.
The average adult male produces around 1,500 sperm per second, which adds up to about 130 million sperm per day. This amount can vary depending on factors like age, health, and frequency of ejaculation.
Averagely 2-3 minutes, unless you have an issue called Delayed Ejaculation, where it may take 30 minutes or more
It is possible for a male to ejaculate twice. If a male wants to do this of course it can take a bit of practice. In some instances it can be discovere by accident. One of those most common methods for a male to ejaculate twice is with aid by his partner (or by himself) is to reach the point of ejaculation (cumming/orgasm) and then cease stimulation immediately. This causes the muscles to release only a portion of sperm, usually half or a little more. The technique is sometimes referred to as "denial" or "ruined" ejaculation. Then when the first ejaculation has completed continue the penis stimulation for the remainder of stored sperm to ejaculate. It must be noted that the amount of semen in each of the first and second ejaculation can vary. Sometimes too the penis can ejaculate and lose a vast amount of sperm in the first instance of stimulation denial making it more difficult for the second ejaculation.
