Reproductive cells (spermatozoa or oocytes) that contain half the normal chromosome complement.

Gametes

2

Reproductive organs that produce gametes and hormones .

Gonads

3

The fluid ejaculate that contains spermatozoa and the secretions of accessory glands of the male reproductive tract.

Semen

4

A cell whose meiotic divisions will produce a single ovum and three polar bodies.

Oocyte

5

The functional product of meiosis II, produced after the fertilization of a secondary oocyte.

Ova/Ovum

6

A male gamete; also called sperm.

Spermatozoa

7

The loose-fitting fleshy pouch that encloses the testes of the male.

Scrotum

8

Spermatozoon production.

Spermatogenesis

9

A muscular tube that carries urine from the urinary bladder to the exterior.

Urethra

10

An accessory gland of the ale reproductive tract, contributing roughly one-third of the volume of semen.

Prostate Gland

11

A component of the male external genitalia; a copulatory organ that surrounds the urethra and serves to introduce semen into the female vagina; the developmental equivalent of the female clitoris.

Penis

12

The stiffening of the penis due to the engorgement of the erectile tissues of the corpora cavernous and corpus spongiosum.

Erection

13

Ovum production.

Oogenesis

14

The release of a secondary oocyte, surrounded by cells of the corona radiata, after the rupture of the wall of a tertiary follicle; in females, the periodic release of an oocyte from an ovary.

Ovulation

15

The muscular organ of the female reproductive tract in which implantation, placenta formation, and fetal development occur.

Uterus

16

The inferior portion of the uterus.

Cervix

17

A muscular tube extending between the uterus and the vestibule.

Vagina

18

The mucous membrane lining the uterus.

Endometrium

19

The process of endometrial sloughing.

Menstruation

20

The termination of the uterine cycle. The time that ovulation and menstruation cease.

Menopause

21

An elastic epithelial fold of variable size that partially blocks the entrance to the vagina.

Hymen

22

The ejection of semen from the penis as the result of muscular contractions of the bulbospongiosus and ischiocavernosus muscles.

Ejaculation

23

Ejaculation is associated with intensely pleasurable sensations, and experience known as male ______.

Orgasm

24

The failure of one or both testes to descend into the scrotum by the time of birth.

Cryptorchidism

Painful menstruation.

Dysmenorrhea

26

The failure of menarche to appear before age 16, or a cessation of menstruation for six months or more in a female of reproductive age.

Amenorrhea

28

The inability to achieve or maintain an erection.

Impotence

29

The surgical removal of part or all of a breast containing cancerous glandular tissue.

Mastectomy

30

The examination of breast tissue.

Mammogram

31

The surgical removal of testis.

Orchiectomy

32

The surgical removal of a segment of each ductus deferent, making it impossible for spermatozoa to reach the distal portions of the female reproductive tract.

Vascetomy
