How long sperm can survive in the female body depends on how healthy the sperm are and whether the female is fertile at the time. If there is fertile quality cervical mucus present then sperm can potential survive for up to a week within her body.
Sperm can survive outside of any one body for no more than one hour. Once inside a female body, the amount of time increases by only a few hours. Source: http:/www.thelaboroflove.com/articles/how-long-can-sperm-survive-outside-the-body
Sperms survive 72 hours/ 3 days inside the woman's body.
sperm from a male
The male injects sperm into the female's cloaca. The eggs inside the female are fertilized by this sperm and are incubated inside the female's body until the young are ready to emerge to the outside world.
sperm from a male
Male and female birds mate, and the male places sperm inside the body of the female. This fertilizes the eggs being formed inside the body of the female bird. When they are formed, the female lays the eggs in a nest, keeps them warm with her body until they hatch into baby birds.
The female body does not release or have "sperm" - women have "eggs" that the mans sperm fertilizes to achieve conception.
External fertilization occurs when the egg is fertilized by the sperm outside of the female's body. As when a female fish deposits her eggs on the ground and the male fish ejaculates his sperm over the eggs. Internal fertilisation occurs when the sperm fertilizes the egg inside the female's body. Which is what mammals do, including human beings.
There are a couple reasons that sperm die after being inside of you for more than a few days. 1. Your body temp 98.6 degrees is way to hot for them to survive in. This is the reason the testes are outside a mans body, rather than inside. 2. Once the seminal fluid flushes out of you, there are no more nutrients for the sperm to live off of and the acid level inside you is to strong. Without the alkaline that the seminal fluid provides the sperm cannot survive. Generally after 3 days they will die and be absorbed into your body. It protein :)
Sperm can survive inside a woman's body for up to 5 days. However, their lifespan greatly depends on external factors such as the woman's cervical mucus and fertility. In optimal conditions, the sperm can survive for a shorter duration of around 24-48 hours.
When a sperm cell meets an egg cell, the head of the sperm fuses with the egg. The flagellum of the sperm is lost, its work is finished. The information in the nucleus of the male's sperm can combine with the information in the nucleus of the female's egg to produce an offspring. This important event is called fertilization. If fertilization takes place inside the female's body - as it does in mammals or birds - it is called internal fertilization. If it happens outside the female, in water, it is called external fertilization.
