What are seminal vesicles?
Click to flip
Seminal vesicles are glands in the male reproductive system that secrete fluid that partly composes semen.
Click to flip
Where are seminal vesicles located?
Click to flip
Seminal vesicles are located behind the bladder and above the prostate gland.
Click to flip
What is the primary function of seminal vesicles?
Click to flip
Their primary function is to secrete a significant portion of the fluid that becomes part of semen, providing nutrients for sperm.
Click to flip
What important nutrient do seminal vesicles provide in semen?
Click to flip
Seminal vesicles provide fructose as an energy source for sperm.
Click to flip
How do seminal vesicles contribute to sperm motility?
Click to flip
They secrete fluid that contains substances to promote sperm motility and viability.
Click to flip
What is the acidic, neutral, or alkaline nature of seminal vesicle secretion?
Click to flip
The secretion from seminal vesicles is alkaline.
Click to flip
Do seminal vesicles store sperm?
Click to flip
No, seminal vesicles do not store sperm; they store and secrete fluid that becomes part of semen.
Click to flip
How do seminal vesicles affect the volume of ejaculate?
Click to flip
Seminal vesicles significantly increase the volume of the ejaculate by adding seminal fluid.
Click to flip
What happens if seminal vesicles produce insufficient fluid?
Click to flip
Insufficient fluid production may reduce ejaculate volume and sperm viability.
Click to flip
What types of proteins are found in seminal vesicle fluid?
Click to flip
Seminal vesicle fluid contains enzymes and proteins that facilitate sperm function and mobility.
Click to flip
What role does the seminal vesicle fluid have in fertilization?
Click to flip
Seminal vesicle fluid supports sperm by providing energy, protection, and aiding in motility, essential for fertilization.
Click to flip
Are seminal vesicles present in female reproductive systems?
Click to flip
No, seminal vesicles are not present in female reproductive systems; they are part of the male reproductive system.
Click to flip
How do seminal vesicles influence reproductive success in mammals?
Click to flip
By providing nutrients and a conducive medium, seminal vesicles increase the chances of sperm survival and successful fertilization.
Click to flip
What role does seminal vesicle secretion play in sperm capacitation?
Click to flip
Seminal vesicle secretion provides factors that may contribute to sperm capacitation, making them able to fertilize an egg.
Click to flip
How is the function of seminal vesicles assessed in clinical evaluations?
Click to flip
Classically, seminal vesicle function is assessed in the context of semen analysis or imaging studies like an ultrasound of the reproductive tract.
