Q

Paired set of convoluted pouch-like structures

Usually 2 inches in length

A

Seminal Vesicles

133
Q

Seminal vesicle secretions

acidic or alkaline?

A

Alkaline

Helps to neutralize acidic environment of male urethra and female reproductive tract (these would kill sperm)

134
Q

Seminal vesicle secretions

viscous or thin?

A

Viscous

Helps to keep semen in female reproductive tract longer to increase chances of fertilization

135
Q

Seminal vesicle secretions contain

A

Fructose
used for ATP production by sperm

Prostaglandins
Contributes to sperm motility and viability
Thought to stimulate smooth muscle contraction within female reproductive tract (help move sperm towards ova)

Clotting proteins
Helps semen coagulate after ejaculation (helps semen stay in female reproductive tract longer)

136
Q

Single, walnut/doughnut shaped gland

Approximate size of a golf ball

Inferior to bladder

Surrounds prostatic urethra

Grows slowly in size from birth to puberty

At puberty grows rapidly until age 30 then remains stable until age 45 when further enlargement may occur

A

Prostate

Milky fluid
Slightly acidic (pH of 6.5)
A

Prostatic fluid

140
Q

Prostatic fluid

contains?

A

1) Citric acid- used for ATP production

2) Proteolytic enzymes- help break down clotting factors in seminal vesicle fluid (PPHAL)
- -Prostate specific antigen
- -Pepsinogen
- -Hyaluronidase
- -Amylase
- -Lysozyme

3) Seminalplasmin- decrease number of bacteria in semen
