Terms and definitions of the male reproductive systemTerms and definitions of the male reproductive system

1. Bladder------Stores Urine

3.Vas Deferens---thin cords, passageway and storage place for sperm

4.Penis– Organ of reproduction, it provides a passageway for the urethra carrying urine or sperm. It is also the organ for sexual pleasure, ie the orgasm.

5.Urethra- Passageway for semen and urine. It is about 9 inches long and it goes through the prostate gland. A flap at the opening of the bladder closes prior to ejaculation so urine and semen do not mix.

6. Epididymis– Comma shaped structure by the testes, it stores immature sperm.

7. Foreskin– Fold of loose skin covering the penis. The skin is cut away during a procedure called circumcision.

8. Glans Penis– Tip or head of the penis

9. Testicle (Testes)– gonads inside the scrotum, they produce testosterone and sperm at the onset of puberty.

10. Scrotum– Sac like pouch in the groin that holds the testes and regulates the temperature of the testes so sperm are viable.

11. Seminal Vesicles– 2 glands at the end of the vas deferens that secrete fluid that provide energy to the sperm, the fluid is called semen.

13 Prostate Gland- Provides fluid for the sperm to live longer and it neutralizes the vagina so the sperm do not die rapidly.

15. Cowpers Glands- These are small glands on each side of the urethra that secrete a lubricating fluid as the male becomes aroused. The fluid contains sperm. A pregnancy can occur without penetration of the vagina or ejaculation!Woops!!

Male PhysiologyMale PhysiologyErection- an involuntary reaction that occurs when the penis fills with blood. This is caused by a large number of sensitive nerve ending in the penis and scrotum

Circumcision

Pros and Cons to circumcision

Easier to cleanPeer pressureReligious reasons

The trauma involvedDecrease in Sexual stimulation

Pathway of the Sperm

Ejaculated out of the penis

Fact:A sperm takes four weeks to mature

Sperm are the smallest cells in the body, 0.05 millimeters

About 300 million mature everyday

They can live about 1 month, then they die.

They have to swim about 8 inches to reach the egg.

Sperm swim about 5 mm per minute, and it’s in fact, five body lengths of the sperm per second. So if you scaled them up, if they were the size of a salmon, that would be the equivalent of the salmon swimming along at 500 miles an hour, or a whale doing 15,000 miles an hour. So the sperm are pretty snappy. They get to the egg pretty fast, certainly within a day or so.

I need a nap after

all that !

Ejaculation- the expulsion of the seminal fluid from the penis. A normal amount is equal to a teaspoon and contains approximately 300-500 million sperm!!!! OMG how many sperm does it take to fertilize an egg???

FYI- Sperm can live up to 5 days!

Orgasm- explosive discharge of neuromuscular tension as a result of muscle contraction. It helps sperm move through the urethra. There is a rest period between orgasms.

Boys

Vasectomy, cutting the Vas Deferens

Pros--- Easier , simple procedure It’s relatively permanent

Cons---Swelling, pain, infection

Prostate Cancer in the USA

The exact causes of bowel cancer are not certain, but it is believed that lifestyle and environmental factors, such as a high-fat, low-fiber diet and a lack of physical activity can contribute to the disease. Polyps on the bowel, even if initially benign, can become malignant and lead to cancer. Colonoscopies are recommended for middle age men for early diagnosis.

Second highest rating

Inguinal Hernia– a weakness in the tissue causing the intestines to push through the abdominal cavity and into the scrotum. This is common in males
