Reproduction

Question 1

Menstrual cycle day one

Answer 1

Your period starts, estrogen hormone increases

Question 2

Menstrual cycle day 14

Answer 2

An LH surge causes ovulation

Question 3

Menstrual cycle day 21

Answer 3

High progesterone levels cause endometrium to be at its thickest point

Question 4

Menstrual cycle day 28

Answer 4

Progesterone and female hormones reduce causing endometrium lining to degenerate

Question 5

What organs are involved in making seman

Answer 5

Seminal vesicles, prostate gland, and bulbourethral gland

Question 6

Production of testosterone

Answer 6

LH controls the production of testosterone by interstitial cells in the testes and ovaries

Question 7

Where is estrogen made

Answer 7

produced primarily in the ovaries, corpus luteum, and placenta

Question 8

Where is progesterone made

Answer 8

Ovaries and testes

Question 9

Sertoli cells job

Answer 9

To nourish the developing sperm cells and release LH hormone

Question 10

Sperm and egg similarities

Answer 10

They both contain 23 chromosomes

Question 11

What is fertilization

Answer 11

When a sperm cell enters the egg cell

Question 12

What is pregnancy

Answer 12

When the fertilized egg cell connects to the endometrium in the uterus

Question 13

Anterior hormones

Answer 13

LH and FSH

Question 14

Posterior hormones

Answer 14

Oxytocin

Question 15

Where does fertilization occur

Answer 15

Fallopian tubes

Question 16

Why are testes on the outside

Answer 16

To keep cool. Sperm cannot survive in hot temperatures

Question 17

when removing uterus why do they keep the ovaries

Answer 17

They make estrogen

Question 18

GnRH

Answer 18

Released by hypothalamus. Causes relapse of LH, FSH, estrogen

Question 19

LH

Answer 19

Controls production of testosterone. Promotes estrogen production in ovaries. Surges on day 13

Question 20

FSH

Answer 20

Promotes sperm production, testosterone production, stimulates follicle in ovary to develop, causes estrogen production, increases in day 6-13

Question 21

Testosterone

Answer 21

Develops penis/testes in puberty. Matures sperm

Question 22

Estrogen

Answer 22

Hypothalamus detects estrogen and causes positive feedback day 1-13. Surges on day 13. Becomes negative feedback after ovulation. Thickens uterus day 6-13.

Question 23

Progesterone

Answer 23

Produced by corpus luteum. Predominate days 15-28. Makes endometrium double and thickness plus secrete mucus.

Question 24

Inhibin

Answer 24

Released by Sertoli cells. Increase with sperm production. It negative feedback to maintain sperm levels

Question 25

HGC

Answer 25

(Pregnancy) maintains corpus luteum. Produced by embryo then placenta. Stops GNRH plus FSH production. Signals for pregnancy test.

Question 26

Oxytocin

Answer 26

(Pregnancy/labor) induces birth. Made in hypothalamus, stored in posterior pituitary. Causes uterus to contract. Positive feedback mechanism birth plus breast-feeding. Simulates mammary glands from milk

Question 27

Prostaglandins

Answer 27

Helps propel sperm. Helps uterus contract/induces birth

Question 28

Corpus luteum job

Answer 28

a follicle that housed a maturing egg

Question 29

Where are sperm made

Answer 29

Seminiferous tubules. After emerging from the testes, sperm are stored in the epididymis. Sperm mature here

Question 30

Path of sperm

Answer 30

Testes, epididymis, vas deferens, urethra, penis

Question 31

Follicular phase

Answer 31

1-14. Menstruation occurs followed by rebuilding of uterine lining. Increased levels of female hormones. estrogen predominates. Surge of estrogen on day 13

Question 32

Luteal phase

Answer 32

15-28. Progesterone predominates. Released by corpus luteum. Progesterone makes endometrium double and thickness and secrete mucus. Around day 25 corpus luteum starts to degenerate. Progesterone decreases. Endometrium mining degenerates

Question 33

What hormones in birth control

Answer 33

Estrogen and progesterone

Question 34

What hormone does a pregnancy test look for

Answer 34

HGC

Question 35

Negative to steroids

Answer 35

Balding, acne, breast enlargement in men opposite for women, kidney disease, reduced testes size, stunted growth, increased sizes of ovaries, high blood pressure

Question 36

How does a vasectomy work

Answer 36

You cut both of the vas deferens. Sperm stay in the testicles.
