TestisSeminiferous tubulesProstateSpermatic sac
This is the testis!
The testis is the male gonad (sex organ) held inside the scrotum, and it produces sperm and the hormone testosterone.
Fallopian tubeProstate DuctVas deferensUrethra
This is the Vas Deferens!
The vas deferens, also known as the ductus deferens, is a coiled tube that carries the sperm from the testes during ejaculation.
Cowper's glandPenile lymph nodeEpididymisProstate gland
This is the prostate gland!
The prostate gland sits right below the bladder and surrounds the urethra, which carries urine out of the body. It produces seminal fluid, which helps to nourish and transport sperm as it leaves the body through ejaculation.
ClitorisSpermatic artertyPampiniform plexusUrethra
This is the urethra!
The urethra carries urine from the bladder to the outside of the body. It also carries semen from the ejaculatory duct when muscles around the base of the penis contract to force it out of the body during ejaculation.
This is the penis!
Yup, this is just the actual penis! It's the external part of the male reproductive organ and contains the urethra, which carries urine and semen outside the body.
Seminal vesicleCorpus cavernosumEjaculatory sacCervix
This is the seminal vesicle!
The seminal vesicle is a pair of glands that open into the vas deferens and secrete some of the fluid that makes up semen. This fluid contains enzymes, protein, fructose, and vitamins to support the sperm. The fluid also has an alkaline pH to help neutralize the acidic environment of the vagina.
This is the anus!
The anus is the opening of the rectum, where feces can exit. It’s also the point of entry for anal insertion and prostate stimulation.
Seminiferous sacBladderStomachPosterior kidney
This is the bladder!
The bladder is a hollow sac that collects and holds urine until it's released during urination through the urethra, which goes through the penis.
Urethral openingEjaculatory ductLymphatic veinEpididymis
This is the ejaculatory duct!
The ejaculatory duct passes through the prostate and empties semen that contains sperm and fluid from the vas deferens and seminal vesicle into the urethra during ejaculation.
Bartholin glandCowper's glandSpermatic lymph nodeColonic polyp
This is the Cowper's gland!
The Cowper's glands, also called the ulbourethral glands, are small and sit under the prostate. They add fluids to semen full of proteins and natural lubricants that help to wash out the urethra of acidic urine before semen enters for ejaculation. They produce pre-ejaculate!
Testicular sacBartholin's glandEpididymisSeminal vesicle head
This is the epididymis!
The epididymis (say that three times fast!) is a curved tube on the back of the testis. It stores newly made sperm for about a week so it can mature to a point where it's able to fertilize an egg, at which point it passes through the tail of the epididymis into the vas deferens.
Pampiniform plexusSeminal ductSpermatic cordEfferent ductules
These are the efferent ductules!
These are a group of 15–20 ducts that serve as a pathway for sperm between the testes and the epididymis. They help to reabsorb water from the luminal fluid (which carries sperm) to increase the concentration of sperm during ejaculation.
Spermatic cordSeminiferous tubulesLabia majoraPampiniform plexus
These are the seminiferous tubules!
The seminiferous tubules make up most of the testes. They are the actual site for the meiosis of cells into gametes, or the creation of sperm cells for sexual reproduction. These mature in the epididymis before they can fertilize an egg or ovum.
Spermatic cordTesticular arteryUreterFallopian tube
This is the ureter!
The ureter carries urine from the kidneys to the bladder, where it's held before urination.
This is the rectum!
The rectum is the last several inches of the large intestine before the anus. It serves to pass feces through the body and it contains muscle.
Seminiferous tubuleUterine wallCorpus cavernosumPubic bone
This is the pubic bone!
The pubic bone is connected to the pelvis and helps make up the male pelvic floor and give it structure.
Corpus cavernosumPubis majorisSpermatic tissueGlans penis
This is the corpus cavernosum!
The corpus cavernosa are two cylindrical bodies of tissue inside the entire length of the penis. They are spongy so when the nerve response of sexual arousal sends blood to the penis, the corpus cavernosa fills with blood. The sudden increase in blood volume causes stiffening and expanding of the penis, otherwise known as an erection!
Pampiniform plexusForeskinGlans penisSpermatic sac
This is the glans penis!
This structure is the head of the penis, where the corpus cavernosum ends. It contains the opening for the urethra, where urine and semen exit the penis.
