1

Primary sex organs: male, females

testes
ovaries

2

Sperm and ovum are these types of cells and are denoted in this manor

gamates, haploid(n)

3

Fertilization results in this

zygot

4

Sex chromosomes: male, female

XY
XX

5

The zygot grows through

mitosis

6

These develop in early male embryo

seminiferous tubules
intersitial cells

7

Indifferent gonads are found at this stage

early embryonic

8

This determines if indifferent gonads will form testes or ovaries, and results from this

TDF, testes determining factory.
SRY gene on Y chromosome

9

When do the ovaries develop in the embryo

follicles do not develop until third trimester

10

Testes produce these two things

testosterone
Mullerian inhibition factor (MIF)

11

MIF degenerates this

Paramesonephric (mullerian) duct

12

The paramesonephric (mullerian) duct becomes this in men, and this in woman

Degenerates in men
froms uterus and uterine tubes in females

13

Epididymides, ductus deferentia, ejaculatory ducts are formed from this in the presence of this

mesonephric (wolffian) duct
estosterone

14

This happens to the mesonephric (wolffian) duct in females

degenerates because there is no testosterone

15

other embryonic structures in the presence of testosterone become these

prostate
penis
scrotum

16

other embryonic structures without the presence of testosterone become these

vagina
labia
clitoris

17

At this time an ultrasound can be used to determine the sex of an embryo/child

12-13 week

18

Two structures that regulate gonadal function

hypothalamus
anterior pituitary

19

THis is released by the hypothalamust and affects this organ

gonadaltropic releasing hormone (GnRH)
anterior pituitary

20

THis is released by the anterior pituitary in response to GnRH

Gonadotropins (FSH and LH)

21

FSH stands for

folical stimulating hormone

22

LH stands for

Leutinizing hormone

23

T/F: FSH and LH are found in only females

F, found in both males and females

24

Gonadotropins act on this

gonads

25

What are the sex steroids

testosterone
estrogen

26

In the presence of gonadotropins the gonads release/produce this

sex steroids
inhibin
gamets

27

Sex steroids have this type of affect on the hypothalamus and anterior pituitary

negative

28

primary sex organ in the male

testis

29

testes produce this

sperm

30

maturation of the sperm takes place in this structure

epididymis
