Seminiferous tubules

Tightly coiled tubules in the tested in which sperm cells are formed

1

Vasa efferentia

Larger tubes within the testes, into which Soren move after being produced in the seminiferous tubules

2

Epididymis

Tubular structure on each testis in which sperm cells mature

3

Vas deferens

Tube that leads sperm upward from each test is to the seminal vesicles

4

Anarchism

Rare birth defect in which both testes are lacking

5

Cryptorchidism

Condition in which the testes have not descended into the scrotum prior to birth

6

Monorchidism

Presence of only one test is in the scrotum

7

Testicular failure

Lack of sperm and or hormone production by the testes

8

Epididymitis

Inflammation of the epididymis of the testis

9

Frenulum

Thin, tightly drawn fold of skin on the underside of the penile glans; it is highly sensitive

10

Shaft

The cylindrical base of the penis that contains three volume of spongy tissue : two corpora . Cavernosa and a corpus spongiosum

11

Phimosis

A condition in which the penile foreskin is too long and right to retract easily

12

Priapism

Continuant , undesired and painful erection of the penis that's at longer then 4 hours

13

Agenesis of the penis

A congenital condition in which the penis is undersized and nonfunctional

14

Hypospadias

Birth defect caused by incomplete closure of the urethra during feral development

15

Epispadias

Birth defect in which the urinary bladder empties through an abdominal opening and the urethra is malformed

16

Seminal vesicle

Gland at the end of each vas deferens that secretes a chemical that helps stern become motile

17

Prostate gland

Located beneath the urinaru bladder in the male ; it produces some of the secretions in semen

18

Cowpeas glands / bulbourethral glands

Two small glands in the male that secrete an alkaline fluid into the urethra during sexual arousal

19

Benign prostatic hyperplasia

Enlargement of the prostate gland that is not caused by malignancy

20

Interstitial cell stimulating hormone

Pituitary hormone that stimulates the testes to secrete testosterone ; known as lutenizing hormone in females

21

Spermatocytes

Cells lining the seminiferous tubules from which sperm cells are produced

22

Retrograde ejaculation

Abnormal passage of semen I to the urinary bladder at the time of ejaculation
