Washed sperm is supposed to only live for 6-12 hours, but sometimes as long as 24 -- not nearly as long as sperm can live in fertile cervical mucus (sperm can live up to 5 days in fertile mucus, 2-3 days being pretty common). This is why timing is so important.

Sperm ejaculated into a woman's vagina remain alive in the mucus of the cervix and are able to fertilize an egg for three to five days. Sperm ejaculated outside the body usually live only a few hours.

This varies with the mosquito species and the time of the year. Some species may only live for less than a week, while others can live for several months over the winter months. (BACK)

Normal, healthy sperm live approximately 48-72 hours. (Abnormal sperm may have a shorter life, which may vary according to sperm health.) We do know that washed sperm can survive in the IVF incubator for up to 72 hours. That would be considered the upper practical limit.

Although staph can live on surfaces for days to weeks, it doesn’t mean that it will make a person sick. Staph has to get off the surface and onto someone’s skin, where the organism may or may not survive due to the presence of competing organisms. Even if it survives on someone’s skin, it may simply live on the skin and not cause an infection. In order to cause an infection there has to be a break in the integrity of the skin.

Well I guess that depends on who you talk to--Most farmers who are in the egg producing business will say 2 years. Those who are in the meat producing business will say 6 months--Those who keep birds as pets (with names) or who are not interested in maximum production of eggs, will find that chickens can live up to 8 or 10 years.

A.: Sperm require around three months to fully mature. Once you remove the offending condition then three months are needed for a new cycle of sperm to be released. Some men see improvements in their semen analysis sooner if the offending condition is minor. Some men take longer to improve if the size and firmness of their testicles are poor.

Sperms live in your body 78 days from the beginning of their development until they are ejaculated. It therefore takes a minimum of four months after surgery, to see significant improvement in semen analysis. Improvement can be seen for up to two years.

In very general terms, the larger a bird is, the longer its life expectancy. For small birds, such as migratory songbirds (warblers, vireos, etc.) the average life expectancy may be as little as two years. This short life expectancy is due to the many hazards birds face from birth: predators, disease, accidents, migration, starvation, habitat loss, and hunting, among others. Some individual birds have survived surprisingly long, including a cardinal (13.

The grains or plant live, with proper care as long as their owners. Kefir cultures reproduce themselves and do not know a physical death. We recommend making one litre (1½ pints) each time, though quantities of up to 2 litres is possible. Clean the Kefir grains daily by placing them in a sieve then allow medium flow of water to wash through the grains.

The average dog lives about 10-12 years. Unlike most animals, smaller breeds tend to live longer than larger ones.

Many items, especially those that are made of cotton, can shrink if the manufacturer's instructions are not followed. We recommend following the cleaning directions that manufacturers put on labels.

The product is design to be used according to the directions on the bottle, which include washing the fabric before using it. Using printed fabric that has not been washed would be like using fabric that had been dyed with fiber reactive dye and not washed. Not all the ink molecules react with the fabric. The loose ink molecules and the chemical need to be washed away.

Once they reach the butterfly stage, most live an average of about 10 days. There are exceptions in the Conservatory. The Longwing butterflies can live 3 or more months.

Cairns can live well into their teens, and most are still very active and alert at 10 years of age and older.
