A new life is born when a sperm and an egg are fertilized in a woman’s body. This is a fact that most of us know. However, not many of us know how sperm is formed, how long it survives in the male reproductive system? And how long does sperm survive when it enters a woman’s body? Let’s take a look at these facts and learn about the life span of sperm. 1. In the male reproductive system Sperm is produced by the testes. During this process, the spermatogenic cells in the seminiferous tubules continue to divide and eventually form sperm cells. These are immature cells that then pass to the epididymis for maturation. It takes about two to three weeks for sperm to mature in the epididymis, and this is where it stays once it is fully mature, waiting for ejaculation to enter the female reproductive system during a male orgasm. Sperm can survive in the male body for about 74 days. If they are not released during ejaculation, they die and are then reabsorbed by the male body. Various factors will determine the health of the sperm and how long the ejaculate can survive during a male orgasm. 2, After In Vitro Ejaculation When you ejaculate sperm mixes with a variety of nutrients and fluids, mainly from the prostate and seminal vesicles, and is then released from the penis. Your semen can contain anywhere from 100-400 million sperm. When sperm are ejaculated outside the body, such as during masturbation or when the penis is pulled out of the vagina before ejaculation, the sperm can only survive for a few minutes. People who rely on this method to avoid unwanted pregnancies should make sure that the ejaculate does not come close to the woman’s vagina. Once dried up, sperm cannot survive, nor can they survive for more than 20 to 60 minutes after exposure to the environment. 3. Inside the female body Sperm survival time inside the female body The main purpose of sperm is to fertilize and impregnate an egg. It is important for anyone trying to conceive to know how long sperm can survive after entering the female reproductive system. Due to the acidic nature of vaginal secretions, sperm cannot survive for more than six hours in a woman’s vagina. Sperm have a much higher chance of surviving when they enter the woman’s body through the cervical opening. The length of time that sperm survives in the woman’s body depends on different conditions. Poor sperm motility and the presence of anti-sperm antibodies can affect it. If the sperm is normal, the cervical mucus is normal, and the vaginal and uterine environments are suitable, most sperm cells can easily survive for 6 to 7 days in the woman’s fallopian tubes, which is where it is most likely to fertilize the egg. However reason is plentiful and reality is bone dry, all conditions are perfect in few cases and the average time most sperm survive is 3 to 4 days. As long as the sperm is alive and present in the female reproductive system, fertilization is possible. But the optimal ability to fertilize is 2 to 3 days, and their viability and morphology will determine whether they can reach and fertilize the egg. If they are unable to swim forward quickly or are not in the right state of mind, the chances of them dying in the uterus without fertilizing the egg tend to rise. Only one sperm is able to fertilize the egg. Sooner or later, the remaining sperm will die. Keep in mind that sperm are constantly dying in the female reproductive system. So as time passes more and more sperm will continue to die. This is why the best way to get pregnant is to have sex every 2 to 3 days so that there is always some sperm in the female reproductive system waiting for the egg to be fertilized. If the temperature is lowered, the sperm can survive for up to a few weeks; if frozen in liquid nitrogen, the sperm can survive even longer and can even be stored for long periods of time. 4, in a person’s mouth The temperature of the mouth is higher than that of the outside of the body, moist enough, with gums, nooks and crannies. Relative to the outside world, it is a very good environment for survival. It can theoretically survive for 1-2 days. 5. On the skin Sperm can only survive for a few minutes outside the body. However, the length of survival can vary significantly depending on the surface or environment on which the spermatozoon is located. 6. In the bathroom Sperm can survive that much longer in warm water in the bathtub than on dry surfaces, and the reason remains wetness. “Sperm like warm and moist environments. 7, Other places Hair, confetti, carpeting, curtains or on the floor of a car, to name a few, are the worst places for sperm to live, and in the first few minutes, most of them will die as the semen dries out. But that doesn’t mean the DNA in the sperm also dies off. “The sperm loses its activity, but the DNA in it is something that can always survive, and that’s what forensics and the police can use haha.
