The male reproductive organs produce and release sperm. Sperm is produced in the testicles. The vas deferens connect the testes to the rest of the male reproductive organs by extending over the pelvic bone or ilium and wrapping around the ampulla, seminal vesicle, and prostate. But do you know how much sperm testicles can make in a second?
During spermatogenesis, your testicles are constantly producing new sperm. The entire procedure takes about 64 days. During this time, your testicles produce millions of sperm per day, roughly 1,500 per second.
How Long Does it Take to Produce Sperm?
Every day, you produce sperm, but a complete sperm regeneration cycle called spermatogenesis takes about 64 days.
Spermatogenesis refers to the entire process of sperm production and maturation. It constantly supplies your body with sperm able to travel through the vagina to an unfertilized ovum in a woman’s ovaries to conceive. (Source: Healthline)
What is the Sperm Production Rate?
During spermatogenesis, your testicles produce millions of sperm per day, roughly 1,500 per second. You can regenerate up to 8 billion sperm by the end of a complete sperm production cycle.
This may appear excessive, but a single milliliter of sperm contains anywhere from 20 to 300 million sperm cells. Your body keeps a surplus to ensure a fresh supply for conception. (Source: Healthline)
What is the Sperm Production Cycle?
The sperm regeneration cycle includes the following steps:
The division of diploid sperm cells into haploid spermatids capable of carrying genetic information.
Sperm maturation in the testicles, specifically in the seminiferous tubules. Hormones aid spermatids in their development into spermatozoa. The sperm then remains in the testicles until it is nearly mature. A mature sperm has a head that contains genetic material and a tail that assists the sperm in traveling through the female body for fertilization.
Sperm movement into the epididymis, a sperm-storing tube connected to your testicles. The epididymis is responsible for preserving sperm until ejaculation. This is also the stage at which sperm acquire motility, or the ability to move. They can travel because they are released in seminal fluid or semen during ejaculation. (Source: Healthline)
How Long Does Sperm Last After Ejaculation?
When sperm are exposed to air, they can die quickly. The length of time they live is heavily influenced by environmental factors and how quickly they dry up.
If you have a procedure like intrauterine insemination (IUI) or in vitro fertilization (IVF), keep in mind that washed sperm can last up to 72 hours in an incubator. Frozen sperm can be stored for years if kept in a properly controlled environment.
Sperm ejaculated into a woman can survive in the uterus for five days. This is why women can become pregnant while menstruating if they have unprotected sex. If you ovulate soon after finishing your period, the sperm may still be alive and capable of fertilizing the egg.
It takes approximately 2.5 months to progress from a germ cell to a mature sperm cell capable of egg fertilization. (Source: Healthline)
