What are the accessory reproductive organs of human male?

The accessory reproductive organs of the human male are:

a. Epididymis: It is a long, highly convoluted tube that resides on the back of each testes and is divided into three sections: the caput, corpus, and cauda. It serves as a site for sperm maturation and storage.

b. Vas deferens (Ductus deferens): It is a muscular tube that connects each epididymis to the ejaculatory ducts. It transports mature sperms from the epididymis during ejaculation.

c. Seminal Vesicles: They are two small sac-like structures located near the bladder. They produce a fluid rich in fructose, citric acid, and prostaglandins that contributes to the seminal fluid.

d. Prostate Gland: It is a doughnut-shaped gland that surrounds the urethra just below the bladder. It secretes a milky, alkaline fluid that forms a major part of the seminal fluid and helps neutralize the acidic environment of the vagina, improving sperm survival.

e. Bulbourethral Glands (Cowper's Glands): These are two small glands located below the prostate gland. They produce a clear, viscous fluid that serves as a lubricant during sexual arousal and helps to clean the urethra before ejaculation.

f. Urethra: It serves as a common pathway for both urine and semen. During ejaculation, the muscles surrounding the urethra contract to propel semen out of the body.

g. Penis: It is the external organ through which semen is released during ejaculation. It becomes erect due to increased blood flow during sexual arousal, enabling the penetration during sexual intercourse.
