1. Pair of epididymides
2. Paired vas deferens
3. Pair of ejaculatory ducts
4. The urethra
5. Pair of seminal vesicles
6. The prostate
7. Pair of bulbourethral glands

4

What do accessory glands produce?

Secretions that nourish, transport, and mature sperm

5

What are the supporting structures of the male reproduction system? (3)

1. Scrotum
2. Penis
3. Pair of spermatic cords

6

What are the 2 primary functions of the testes?

1. Spermatogenesis
2. Secretes testosterone

7

Spermatogenesis

Production of spermatozoa (sperm), the male gametes, or reproductive cells

8

What produces sperm?

Seminiferous tubules

9

What kind of hormone is testosterone? (2)

1. Steroid hormone
2. Major androgen
- masculinizing hormone

10

What are steroid hormones produced by?

Interstitial cells

11

When does sperm mature?

As they pass through the long and convoluted epididymis

12

Where is sperm stored?

In the epididymis

13

What is the hormone that controls sperm production?

FSH

14

Where does FSH get secreted from?

The anterior pituitary gland

15

3. Smooth muscle

16

How many compartments is the scrotum divided into?

2

17

What are in the 2 compartments of the scrotum? (3)

1. One testis
2. One epididymis
3. The testicular end of a spermatic cord

18

Where does the scrotum lay? (3)

22

What are the testes suspended by?

The spermatic cord

23

How many layers of tissue are there surrounding the testes?

3

24

What are the 3 tissue layers surrounding the testes?

1. Tunica vaginalis
2. Tunica albuginea
3. Tunica vascularous

25

Tunica vaginalis

Double membrane, forming the outer covering of the testes

26

Tunica albuginea

Fibrous covering beneath the tunica vaginalis that surrounds the testes

27

What does the tunica albuginea?

Ingrowths form septa that divides the glandular structure of the testes into lobules

28

Tunica vasculosa

Network of capillaries supported by delicate connective tissue
