Benign Prostate Hyperplasia Flashcards
what does the prostate gland do?
contributes for 25% of the ejaculation fluid
what is the role of citric acid in ejaculation fluid?
used in oxidative metabolism, which provides sperm with energy.
what is the role of G Proteolytic enzymes in ejaculation fluid?
Examples: prostate specific antigen (PSA), pepsinogen and hyaluronidase
-which help facilitate sperm motility via liquefaction of seminal fluid.
what is the role of G Seminal plasmin in ejaculation fluid?
contributes to sperm motility and also has potent antimicrobial activity, thereby reducing the number of naturally occurring bacteria in the ejaculate and the lower section of the female reproductive tract.
what is the homologous gland in females for the prostate gland in males?
the scene’s gland
where is the prostate gland found?
at the base of the bladder, surrounding the urethra and adjacent to the rectum
what stimulates the growth of prostate?
rising levels of testosterone at puberty
what does the seminal fluid do?
Functions to enhance motility of sperm
-seminal fluid is thin, milky coloured and alkaline
what are the 5 lobes of the prostate?
- Anterior – Front of urethra, no glands
- Median – Between urethra and ejaculatory ducts; gland rich
- Posterior – Behind urethra; contains glands (- Digital exam)
4and5. Right/Left lateral – either side of urethra; many glands
what are the 4 zones of the prostate?
- transitional
- central
- peripheral
- fibromuscular stroma
where is the transitional zone?
-the smallest part of prostate surrounding the urethra - main location for BPH
where is the central zone?
- Outside the transition zone.
- where the ejaculatory duct is found
where is the peripheral zone?
main part of the prostate and is the common site for prostate cancer
what is prostatitis?
Pain in the perineum, lower abdomen, testicles, penis, and with ejaculation, bladder irritation, bladder outlet obstruction, and sometimes blood in the semen
is benign prostate hyperplasia (BPH) malignant or non-malignant?
non-malignant growth of the prostate
