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