How Long Does A Sperm Last?

There are several questions about the sperm life cycle in different mediums, such as; how long does sperm last in a pool, in hot water, outside, and in the womb. We will consider how long it takes for sperm to die in open air, and also how long sperm can live inside you to get pregnant.

The testicles are where sperm cells are made, and sperm growth takes about three months. Around 100 million sperm are released through a man’s semen during each ejaculation. Few sperm will make it through the vagina and into the fallopian tubes. The ones that make it to the cervical fluid can live, proceed toward the fallopian tubes, and wait for the egg to arrive from the ovaries for around five days.

The environment they are released into and how quickly the fluid protecting the sperm cells dries up will determine just how long they can last.

The sperm life cycle and how long it lasts under various circumstances, such as how long it lasts in a woman’s body, how long it last outside the body, in a condom, how long a sperm can be kept, important notes to grasp and some myths about sperm are explained in this article.

How long does sperm last in a woman’s reproductive system?

After sexual activity, healthy sperm can survive for a few hours to five days. The environment that the sperm are in completely determines how long they will live inside the vagina. The sperm’s longevity is influenced by the characteristics of the woman’s uterus, vagina, and fallopian tubes. Only the strongest sperm among those that make the journey will be able to penetrate the egg’s thick protective shell and successfully fertilize it.

Although the proper circumstances are necessary for this. By manufacturing a specific form of cervical mucus that shields sperm and makes it simpler for them to reach the fallopian tubes around the time of fertility, our systems can encourage sperm survival. 

The cervical mucus’s consistency has a significant impact. The cervical mucus changes during ovulation due to hormonal changes, providing a survival benefit that prevents sperm from dying. The mucus thins instead of maintaining its typically opaque structure, creating the ideal environment for sperm hosting while yet allowing movement.

Cervical “crypts,” which are tiny openings of the cervical canal, are another way the cervix stores sperm around the time of ovulation. These crypts can operate as short-term banks for sperm, which is gradually released over time to improve the likelihood of conception.

This indicates that the “fertile window” can last for up to five days before ovulation. As it’s difficult to determine the precise moment of ovulation, it also means that you could have sex today but not fertilize the egg until a few days later. So having intercourse with your partner before you ovulate won’t stop a pregnancy. This is the case with the majority of pregnancies. It’s critical to understand this whether you’re trying to get pregnant or trying to avoid getting pregnant.

How long does sperm last outside the body? 

The sperm life cycle is intricate; fresh sperm is constantly produced and can survive in the testes for so many months. A sperm develops in the testes for roughly 69 to 80 days before moving through the epididymis, which takes at least an additional 2 days. Therefore, sperm are up to three months old when they leave your body. 

Sperm cannot survive outside of our bodies for more than a few minutes without heat and moisture. Sperm becomes dead on a dry surface, such as clothing. Once exposed to air, and outside the body, sperm loses its viability and dies instantly. How long a sperm lasts depends on where it is. Environmental conditions and how quickly they dry out have a significant impact on how long they survive.

Sperm are not expected to live more than a few minutes outside the body, even in a room-temperature environment. Humidity is one of the most important elements impacting sperm survival. Semen, a fluid that protects sperm, is what carries them; once the semen has dissipated, the sperm are left alone. 

Sperm survives in heat. Studies reveal that sperm quality and life are impacted by temperatures higher than those of the human body. However, the likelihood that sperm in a hot tub will swim into her vagina and result in her becoming pregnant is incredibly low. While the scrotal temperature was measured in these experiments, we may infer that heat itself has a detrimental impact on sperm viability. 

Important note

  • It’s advisable to keep the sample near to your body, probably in your pocket, and give it as soon as you can if you need to carry semen for medical reasons.
  • Sperms become fragile once they leave your body. Even when semen is immediately collected and examined in a lab, one in five sperm will be dead and one-third will not be moving in almost half of all samples. 
  • Sperm can survive for five days inside the uterus after it has been ejaculated into a woman. Therefore, having sex without protection while on your period is possible. When you ovulate soon after your menstruation is over, the sperm may still be fertile and still be able to fertilize the egg.
  • Again, are you aware that your fertile days are few and far between during each cycle? An egg cell can only survive after ovulation for 12 to 24 hours. The fertile window lasts a total of six days because sperm can survive in the female body for up to five days. However, having sex just one or two days before ovulation increases your chance of becoming pregnant because it allows the sperm enough time to reach the female egg cell before the sperm cells begin to die

How long can sperm survive in a condom? 

Condoms allow sperm to live for several hours but skin or cloth only allows sperm to survive for a short period. 

How long can sperm be kept? 

Sperm may be preserved alive in a lab for at least a week with the proper care. Sperm may be successfully thawed and revived after being stored in a lab and used in IVF years later.

Some of the important myths that it’s essential to be addressed are: 

  • Sperm survives on sheets, towels, and undergarments, for days?

Sperm cannot typically survive on skin, clothing, or other surfaces for more than a few seconds. The capacity of the sperm in semen to fertilize an egg is significantly reduced when that semen dries out or is subjected to severe temperatures. 

  • Sperm can survive for up to five days inside the uterus. This is why having unprotected sex while menstruating is likely to result in pregnancy.
  • Sperm can’t survive in water, so no. Pregnancy is possible if you engage in unprotected sex while in the water, but you cannot become pregnant by merely being in a hot tub or swimming pool. Any sperm in the water will also be immediately destroyed by any soap or chemicals.
