0

Part of the testis found in the intratubular compartment

Seminiferous tubules: contains Gametes and Sertoli cells

1

Part of the testis found in the peritubular compartment

Leydig cells- produce sex hormones

2

Spermatogenesis starts at _y/o

13 y/o

3

Spermatogonium which remains in the basal compartment of seminiferous tubules

Spermatogonium A

4

Germ cell proliferation occurs in which compartment

Adluminal compartment

5

Formation of acrosome by nuclear shaping and condensation

Spermiogenesis

6

What do you call the Release of spermatids from contact Sertoli cells

Spermiation

7

Part of the spermatozoon which has mitochondria

Mid piece

8

Genes activated for flagellum formation

Tubulin and dynein

9

Sertoli cells secrete which hormones

Antimullerian
Inhibin
Activin

10

Intrinsic regulation of spermatogenesis is by

Leydig cells

11

Low frequency of GnRH pulses effects in which hormone release

Low GnRH- FSH release

High GnRH- LH release

12

This hormone stimulates Leydig cells to produce testosterone

LH

13

This hormone forms blood testis barrier by inducing Sertoli cells to secrete ABP

FSH

14

Even at the time if death this hormone is still at high levels

Testosterone

15

Andropause starts at what age

60y/o

16

Responsible for prostatic secretions
A. Testosterone
B. DHT

A. Testosterone - spermatogenesis
B. DHT - correct

17

Hormone Responsible for descent of testes in fetal life

Testosterone

18

At this month of gestation, testes is located in scrotum
A. 3 mos
B. 4 mos
C. 5 mos
D. 6 mos
E. 7 mos

E. 7 mos

19

Stages in the male sexual act that have PARAsympathetic stimulation

Erection and lubrication - parasympathetic

Emission and ejaculation - sympathetic

20

Beginning phase of arousal
A. Desire
B. Excitement
C. Plateau
D. Orgasm
E. Resolution

A. Desire - physical attraction via pheromones
B. Excitement - beginning phase of arousal CORRECT
C. Plateau - peak phase of sexual excitement
D. Orgasm - climax, semen ejaculated
E. Resolution - post orgasm phase, returns to normal flaccid state

21

Phase of the male sexual response cycle where semen in ejaculated

Orgasm

22

Counters acidity of the vagina

Seminal plasma

23

Capacitation occurs in the

Vagina

24

Impotence in men is known as

Erectile dysfunction

25

A cavernosal sexual arousal disorder
A. Parkinson's
B. Alzheimer's
C. Peyronie's

A. Parkinson's
B. Alzheimer's
