|
Function of the efferent ductules
|
Reabsorbs testicular fluid to concentrate spermatozoa
Estrogen required or reabsorption. |
|
|
Function of epididymis
|
Changes occur on spermatozoa:
1. Changes w/in cell membrane, glycoproteins added 2. Release of acrosome enzymes suppressed 3. Motility of spermatozoa suppressed. |
|
|
Function of ductus deferens
|
Propels sperm to ejaculatory duct, sperm stores here
3 layers of muscularis externa |
|
|
Function of seminal vesicles
|
Produces most of ejaculate
Fluid for energy |
|
|
Function of Prostate gland
|
Induce sperm moltility, alkalinity, concretion (marker to gauge age), and PSA (marker for prostate activity)
|
|
|
Mucosal & submucosal hypertrophy causes
|
bladder problems
caused by inc. DHT and androgens |
|
|
Cancer effects what part of the prostate?
|
Main glands
Not noticed because no urine disruption. |
|
|
Function of bulbourethral glands
|
Primarily lubricating
|
|
|
Affect of age on testosterone and prostate
|
less test-->less tissues that use test-->prostate hypertrophies due to inc. sensitivity of DHT
|
|
|
Lack of sperm
|
Azoospermia
|
|
|
Low # of sperm
|
Oligospermia
|
|
|
Defect in motility of sperm
|
Asthenozoospermia
|
|
|
3 regions of male urethra
|
1. Prostatic
2. Membranous 3. Penile |
|
|
Gene on SRY of Y chromosome
|
TDG
|
|
|
What cells secrete AMH which suppresses development of female ducts?
|
Sertoli cells
|
|
|
Cells that secrete testosterone
|
Leydig cells
|
|
|
Occurs in female tract
changes in plasma membrane of spermatozoa |
Capacitation
|
|
|
Release of hydrolytic enzymes, occurs in female tract
|
Acrosome
|
|
|
What is the secretory function of the Sertoli cells during spermatogenesis?
|
Secretes:
1. Androgen binding protein: binds test. 2. Inhibin: - feedback on FSH 3. Aromatase: paracrine effect on Leydig cells to dec. test. 4. Activin & follistatin: dec. leydig cell synthesis of test., - feedback on FSH |
