Men produce millions of new sperm cells every day. But they aren’t ready to swim forward and fertilize an egg until they make it to the epididymis, a tube that stores sperm until you ejaculate.
To keep your sperm healthy, be sure to eat healthful foods and avoid unhealthy behaviors. The sperm-boosting foods include fatty fish, eggs, asparagus, nuts, avocados and lean beef.
Sperm Regeneration Cycle
During a full sperm production cycle, or spermatogenesis, men regenerate up to 8 billion sperm. Several million sperm are produced on a daily basis, and one milliliter of semen can contain 200-300 million sperm cells.
Sperm production begins in a system of tiny tubes inside your testicles called the seminiferous tubules. Here germ cells begin to divide and change shape, transforming into the tadpole-like sperm known as spermatids. They are helped along their way by hormones such as testosterone, which promotes cell division and changes in shape. Eventually, spermatids develop their basic tadpole structure of a head and tail, which will allow them to swim into the female reproductive tract and fertilize an egg.
Once fully formed, sperm cells move into a long tube-like structure in the scrotum called the epididymis. Here they continue to mature and fine-tune their ability to swim. When they are ready, sperm cells are ejaculated. Sperm that are not ejaculated will break down and be reabsorbed by the body.
Once sperm leave the body, they can live up to five days outside the body. If sperm are ejaculated during sexual intercourse, they can begin their long journey towards the egg in order to fertilize it and create a baby. However, many sperm cells die on their way, or become trapped and cannot make it to the egg.
Sperm Lifespan
Generally speaking, sperm can survive up to five days outside the body. However, this lifespan depends on the sperm’s environment and physical conditions. For instance, sperm can live longer in water than on dry surfaces like clothing or bedding. This is because they thrive in a warm and wet environment close to their body temperature.
During sexual intercourse, millions of sperm mix with seminal fluids to form semen. After ejaculation, these sperm travel up through the vas deferens to the urethra and exit the body. Once released, sperm can live up to 24 hours if they are in a vagina that is not pregnant and has no other physical barriers.
Then, they can begin their journey to the uterus of the female. Once they reach the cervix, they can survive up to three days and potentially fertilize an egg. However, if the sperm is exposed to air or other environmental changes, they will die within an hour.
Luckily, men can improve their chances of conception by ensuring that their sperm is healthy and in good shape. They can do this by eating a balanced diet and avoiding unhealthy behaviors such as smoking and drinking. Also, they should consider freezing their sperm early in life to make sure they have enough of them when they are ready to start a family.
Sperm Quality
Men have a finite amount of sperm, and once they run out it takes them a while to replenish the amount. The good news is that the quality of sperm doesn’t take as long to replenish. Men can do a lot to improve the quality of their sperm and their chances of conception, including eating healthily and avoiding unhealthy behaviors like smoking.
Men can never completely run out of sperm since they are continually producing it in their testicles. They can, however, experience a decline in sperm quality due to lifestyle factors. These include smoking, a high-fat diet, and exposure to environmental toxins. Exposure to these pollutants can reduce sperm count and cause a variety of health problems.
When it comes to sperm, quality is just as important as quantity. The sperm must be able to successfully reach the egg and fertilize it. In order to do this, the sperm must survive the acidic environment of the vagina and make it through any cervical mucus that might be present.
Men who are experiencing difficulty conceiving should have their sperm quality tested. A doctor can assess the overall sperm count and determine whether it is time to seek treatment. In addition, a doctor can recommend any healthy changes that may help to increase sperm production and enhance fertility.
Sperm Storage
Sperm are found in semen, a whitish fluid that comes out of the penis during ejaculation. During this process, about 500 million sperm are released. When this fluid reaches the vagina, it can fertilize an egg and cause pregnancy. However, sperm can’t live outside of the body for long. As a result, they need to be frozen at very low temperatures in order to preserve them. Sperm cryopreservation, or freezing, has been used for decades and plays a crucial role in fertility treatment.
Frozen sperm is usually divided into one or more vials, with each sample being used for insemination attempts. The number of vials that are needed depends on the man’s individual needs and the fertility specialist’s preference. A sperm sample is typically frozen for about 10 years, after which it will need to be thawed for use in an attempt at conception.
If a man wishes to keep his sperm for longer than 10 years, he can sign a consent form for long term storage at the time of collection. He will also be asked what he would like to have happen with his specimens if he should die before they are used.
Men who don’t want to wait for their sperm to refill can collect it from the testicles using a sterile cup. The sperm bank will give him the instructions for how to do this. They will also arrange infectious disease testing for him at a local laboratory.
