Under normal conditions there is no sperm in male urine as urine is produced by the kidneys and sperm is produced in the male reproductive organs and primarily the testes.
In the seminiferous tubules of the mans testes, germ cells called spermatogonia divide differentiate into spermatocytes.
Sperm production in the male testes basically takes place in the seminiferous tubules which are coiled structures and along the top of each of the testicles is the epididymis which is a cord like structure in which the sperm mature and are stored.
Urine and sperm are separate things although they come out of the same area which is the penis in males.
However male urine can contain some sperm which is a condition called spermaturia and can occur as a result of retrograde ejaculation or other factors.
Retrograde ejaculation is when semen flows into your bladder instead of out through your urethra during ejaculation, which can lead to the sperm being present in your urine.
You can harvest sperm in a testicle or from a testicle.
Sperm can be harvested directly from a testicle or testicles through surgical procedures such as Testicular Sperm Aspiration or Testicular Sperm Extraction which can be done when sperm is not found in your epididymis or when other methods fail.
Testicular sperm aspiration is performed for men that are having sperm retrieved for IVF/ICSI and is done with local anesthesia in an operating room or office and is also coordinated with the mans female partner's egg retrieval.
A needle is inserted into the testicle and tissue and sperm are aspirated and sucked out.
Testicular sperm aspiration is often used for men that have no sperm in their ejaculate "azoospermia" or have a blockage in their reproductive tract, which makes it impossible to retrieve the sperm from the epididymis.
The extracted sperm is used for IVF or In Vitro Fertilization or ICSI Intracytoplasmic Sperm Injection to help couples conceive a baby.
Testicular sperm extraction is a procedure that involves making a small incision or cut in the scrotum to access the mans testicle and then a small sample of testicular tissue is extracted, which is then examined for sperm.
Another way to harvest sperm from the testicle is through microsurgical testicular sperm extraction which is a more refined version of TESE which uses microsurgical techniques to carefully extract sperm from your seminiferous tubules which is where sperm is produced within the testicles.
Sperm comes from both your left and right testicles.
Both of your left and right testicles or testes are responsible for producing sperm and also the male sex hormone.
Your testicles are the primary organs of your male reproductive system that is responsible for producing sperm and they also produce and release testosterone which is a key hormone in male sexual function and development.
For optimal sperm production and over all male reproductive health, both testicles are required for producing sperm.
The sperm is also produced in your seminiferous tubules that are within your testicles and then move to your epididymis, where they mature and are stored.
And during sexual arousal, sperm are then released from your epididymis and travels through your vas deferens to be ejaculated.
And while the prostate does not produce sperm, the prostate does contribute to the production of semen which is the fluid which carries the sperm during ejaculation.
One part of your semen is produced in your prostate and together with your sperm cells from your testicles, the fluid from your seminal vesicle and the secretions are released by another pea sized gland below your prostate which is called the bulbourethral gland and the prostate fluid makes up your semen.
The prostate does many things which includes the production of seminal fluid.
The prostate is a gland which is located in a males reproductive system.
Your prostate produces a fluid which mixes with your sperm from your testicles to form semen.
This fluid also helps to nourish and protect your sperm and makes it easier for the sperm to travel and to fertilize an egg.
A males prostate also regulates ejaculation and contains muscles which contract during ejaculation which force your seminal fluid and sperm out of your urethra.
Your prostate also produces PSA also known as Prostate Specific Antigen which is a protein that plays a role in maintaining the health of your prostate gland.
And having elevated levels of PSA or prostate specific antigens can indicate prostate cancer or other potential prostate problems.
The prostate also supports male fertility by providing a suitable environment for sperm and facilitating the sperms movement.
However the prostate is not essential for life and you can live a long and productive life without a prostate but you won't be fertile and won't be able to get a woman pregnant without a prostate.
The muscles of the prostate also ensure that your semen is pressed into the urethra forcefully and then expelled outwards during ejaculation.
