Flashcards
Seminal Glands (Seminal Vesicles)
Seminal Glands (Seminal Vesicles)
Lie posterior to the bladder and produce secretions that make up 70% of the volume of sperm. Their duct joins the ductus deferens to form the ejaculatory duct.
Prostate Gland
Prostate Gland
Surrounds the urethra inferior to the bladder; smooth muscle contracts during ejaculation and squeezes prostatic secretions into the urethra Secretions play a role in sperm activation and make up 1/3 of semen volume.
Bulbo-urethral Glands
Bulbo-urethral Glands
Paired, pea-sized glands inferior to the prostate, which produce thick mucus that lubricates the glans penis when a male is sexually excited.

Study Notes
Seminal Glands (Seminal Vesicles)
- Lies posterior to the bladder.
- Produces secretions that make up 70% of the volume of sperm.
- The duct joins the ductus deferens to form the ejaculatory duct.
Prostate
- Surrounds the urethra, inferior to the bladder.
- During ejaculation, smooth muscle contracts and squeezes prostatic secretions into the urethra.
- Prostate gland secretions play a role in sperm activation.
- Makes up 1/3 of semen volume.
Bulbo-Urethral Glands
- Paired, pea-sized gland, inferior to the prostate.
- Produces thick mucus that lubricates the glans penis when a male is sexually excited.
Semen
- Milky white, somewhat sticky mixture of accessory gland secretions and sperm.
- The average amount of semen is 2-5ml, and only 10% is sperm.
- There are between 20 and 150 million sperm/milliliter.
- Accessory gland secretions provide a transportation medium and nutrients for sperm.
- It contains chemicals that protect and activate sperm and facilitate their movement.
Semen Composition
- Prostaglandins make it easier for sperm to enter the uterus.
- The hormone relaxin enhances sperm motility.
- ATP provides energy.
- Some ingredients suppress the female immune response so sperm is not targeted by the immune system.
- Antibiotic chemicals destroy bacteria.
- Clotting factors cause semen to coagulate (clot) just after ejaculation so it sticks to the walls of the vagina.
