Health Male Anatomy

The Scrotum Skin that holds the testicles Main purpose; regulate temperature of testicles Protect? Not so much

The Testicles The Latin testis originally meant "witness “ (to testify) Reproductive organ for males Produce sperm cells and testosterone

21:32 The Epididymis Where sperm mature

Vas Deferens Tubes that carry sperm They connect testicle to urethra One tube for each testicle

Prostate Gland Store and secrete an alkaline fluid Neutralizes acidity from vagina so sperm live longer Valves control urine and semen so only one works at a time This is why men find it difficult to urinate when they have an erection.

Seminal Vesicle Also alkaline to neutralize Makes up 60% of semen – the fluid that sperm live in Nourishes sperm

Cowper’s Gland Produces pre-ejaculate to lubricate urethra Usually noticed as a fluid at the opening of the urethra when a male is aroused. May contain sperm to impregnate a female

Urethra Tube that carries semen Tube that carries urine

Semen Made up of sperm – 5% of total fluid ejaculated Made up of semen – 95% of total fluid ejaculated Prostate, Cowper’s and seminal vesicle fluid comprise semen.

Sperm Reproductive cell Contains genetic material (chromosomes) Decides sex of child 200 million to 500 million sperm per ejaculation

Foreskin Skin that covers head of the penis when not erect Parents may elect for removal of foreskin after birth.

Circumcision Removal of foreskin At this time, neither the CDC or SIECUS has determined whether circumcision is beneficial. http://www.siecus.org/index.cfm?fuseaction=Feature.showFeature&featureid=1806&parentid=478

Testicular Torsion Vas deferens becomes twisted and may lose blood supply

Hernia Small Intestine bulges And may protrude from The inguinal canal

Testicular Cancer Abnormal growth Of cells in the testicle Causing cells to mutate And spread Affects males 15-35 Years old

Prostate Cancer Abnormal growth on Prostate gland. Affects men 45-55 years old

Treatment for Prostate Cancer Radioactive Seeds Radiation Chemo Index Finger Size of seed
