What is azoospermia?

Azoospermia is a condition in which there’s no measurable sperm in a man’s ejaculate (semen). Azoospermia leads to male infertility.

How common is azoospermia?

About 1% of all men and 10% to 15% of infertile men have azoospermia.

What are the parts of the male reproductive system?

The male reproductive system is made up of the following:

Testes, or testicles produce sperm (male reproductive cells) in a process called spermatogenesis. produce sperm (male reproductive cells) in a process called spermatogenesis. Seminiferous tubules are tiny tubes that make up most of the tissue of the testes. are tiny tubes that make up most of the tissue of the testes. Epididymis is the structure on the back of each testicle into which mature sperm are moved and stored. is the structure on the back of each testicle into which mature sperm are moved and stored. Vas deferens is the muscular tube that passes from the epididymis into the pelvis then curves around and enters the seminal vesicle. is the muscular tube that passes from the epididymis into the pelvis then curves around and enters the seminal vesicle. Seminal vesicle is a tubular gland that produces and stores most of the fluid ingredients of semen. The vesicle narrows to form a straight duct, the seminal duct, which joins with the vas deferens. is a tubular gland that produces and stores most of the fluid ingredients of semen. The vesicle narrows to form a straight duct, the seminal duct, which joins with the vas deferens. Ejaculatory duct is created when the seminal vesicle duct merges with the vas deferens. The ejaculatory duct passes into the prostate gland and connects with the urethra. is created when the seminal vesicle duct merges with the vas deferens. The ejaculatory duct passes into the prostate gland and connects with the urethra. Urethra is the tube that runs through the penis to eliminate urine from the bladder and semen from the vas deferens. During ejaculation, sperm move from the testes and the epididymis into the vas deferens. Tightening (contraction) of the vas deferens moves the sperm along. Secretions from the seminal vesicle are added and the seminal fluid continues to move forward toward the urethra. Before reaching the urethra, the seminal fluid passes by the prostate gland, which adds a milky fluid to the sperm to form semen. Lastly, the semen is ejaculated (released) through the penis through the urethra. A normal sperm count is considered to be 15 million/mL or more. Men with low sperm counts (oligozoospermia or oligospermia) have a sperm concentration of less than 15 million/mL. If you have azoospermia, you have no measurable sperm in your ejaculate.

Are there different types of azoospermia?

There are two main types of azoospermia:

Obstructive azoospermia: This type of azoospermia means that there is a blockage or missing connection in the epididymis, vas deferens, or elsewhere along your reproductive tract. You are producing sperm but it’s getting blocked from exit so there’s no measurable amount of sperm in your semen. Nonobstructive azoospermia: This type of azoospermia means you have poor or no sperm production due to defects in the structure or function of the testicles or other causes.

How many minutes does it take a woman to release sperm?

Usually, the sperm reaches the egg within 15 to 45 minutes of ejaculation. However, the process could be much longer than that if you haven't ovulated yet by the time you have sex, because sperm can live inside a reproductive tract and wait for an egg for up to five days.

flo.health - Here's how long it takes sperm to reach the egg after sex - Flo Health

We all know that in order to get pregnant, a sperm needs to fertilize an egg. It sounds simple enough, but there’s more to it than you might think. If you have unprotected sex in your fertile window, you might assume that you’re guaranteed to get pregnant. In fact, there’s only a 10% to 33% chance of getting pregnant (depending on how close to ovulation you do it), which shows there are a fair few hurdles standing in the way.

If you’re keen to clue yourself up on all things conception, you probably want to know the details: How long does it actually take for sperm to reach the egg after sex? What does the journey involve? And how many sperm can you realistically expect to make it all the way?

To answer all these burning sex ed questions (and more), we dug into the research and spoke to fertility expert, reproductive endocrinologist, and Flo Medical Board member Dr. Tiffany Jones for a fascinating glimpse at what really goes on inside after sex.
