1

Fetal membrane that forms a fluid-filled sac around the embryo.

Amnion

2

Stage of early embryonic development; the product of cleavage.

Blastocyst

3

Outermost fetal membrane; helps form the placenta.

Chorion

4

Developmental stage extending from fertilization to the end of the eighth week.

Embryo

5

Mucous membrane lining of the uterus.

Endometrium

6

That portion of the male duct system in which sperm mature. Empties into the ductus (or vas) deferens.

Epididymis

7

Fusion of the sperm and egg nuclei.

Fertilization

8

Developmental stage extending from the ninth week of development to birth.

Fetus

9

Sex or germ cell.

Gamete

10

Primary reproductive organ; i.e., the testis of the male or the ovary of the female.

Gonad

11

Production and secretion of milk.

Lactation

12

Nuclear division process that reduces the chromosomal number by half and results in the formation of four haploid (n) cells; occurs only in certain reproductive organs.

Meiosis

13

Period of life when, prompted by hormonal changes, ovulation and menstruation cease.

Menopause

14

The mulberry-like solid mass of blastomeres resulting from cleavage in the early conceptus.

Morula

15

Immature female gamete.

Oocyte

16

Female reproductive organ in which ova (eggs) are produced; female gonad.

Ovary

17

Culmination of pregnancy; giving birth.

Parturition

18

Temporary organ formed from both fetal and maternal tissues that provides nutrients and oxygen to the developing fetus, carries away fetal metabolic wastes, and produces the hormones of pregnancy.

Placenta

19

Adenohypophyseal hormone that stimulates the breasts to produce milk.

Prolactin

20

External sac enclosing the testes.

Scrotum

21

Fluid mixture containing sperm and secretions of the male accessory reproductive glands.

Semen

22

Highly convoluted tubes within the testes; form sperm.

Seminiferous tubule

23

The process of sperm (male gamete) formation; involves meiosis.

Spermatogenesis

24

Male gamete.

Sperm

25

Male primary reproductive organ that produces sperm; male gonad.

Testis

26

Structure bearing arteries and veins connecting the placenta and the fetus.

Umbilical cord

27

Mature ovarian follicle.

Vesicular (Graffian) follicle

28

Female external genitalia.

Vulva

29

Fertilized egg.

Zygote
