Sperm are vital, but also sensitive, therefore they live outside the body for a short time. Like plants, sperm need adequate humidity and temperature to survive, so they have little chance of being outdoors. How long do sperm live outside the body and how much time in the vagina?
How long do sperm live ? It depends on the conditions in which they exist. Let's start at the beginning: 40 millionspermrushes into action with each ejaculation of a fully functional man. But only half of the sperm from one batch of semen is full of vigor and begins the race towards the egg. The second part is extras who don't even want to swing their tail (professionally called a switch). Of the 20 million active sperm cells, 3 million have a chance of fertilization. But everyone knows that one 60-micron toddler is enough to distance the rivals, tear off the cap at the right moment and use the power of his enzymes to force the egg's cell membrane. The rest of the sperm participating in the race die.
How long does sperm live in the vagina?
What if the sperm doesn't meet the egg? They don't give up. If the sperm has landed in the genital tract, where it is warm, nice and cozy, and above all adequately moist - they hide. They can survive in the body of a woman from 2 to even 5 days. Therefore, if we want to avoid pregnancy, we must refrain from intercourse a few days before ovulation, and not only when it occurs. With such an amount and vitality of sperm, it is difficult to imagine that almost every fifth couple in Poland cannot become pregnant.
This is where the sperm sensitivity comes out. Environmental poisoning, a sedentary lifestyle and excessive exploitation of the body due to exhausting work and very intensive sports, obesity, a passion for beer containing phytoestrogens and the use of anabolics to increase muscle mass are very harmful to them. In the semen of "packers", many sperm are deformed, e.g. with two heads or without twigs, and generally less efficient.
