What is the Function of the male reproduction system To produce and store sperm. To introduce the sperm to the female. Produce some of the hormones (Testosterone).

Scrotum The scrotum is the sac that hold the testes Loose, wrinkled pouch of skin that hangs behind and below the penis Primary function is to maintain the testes at approximately 2-4 degrees below normal body temperature. The ideal temperature for testes to produce sperm effectively is 96.8.

Testes Production of sperm Production of male hormone testosterone. Testicular Cancer for men ages 15-34.

Testicular Cancer The most common type of cancer in men aged 15 to 35. It is much more common in Caucasians than in African Americans and usually is diagnosed when a man is in his mid-30s. Warning Signs of Testicular Cancer: Small, hard lump on testicle (may be no larger than the size of a pea, usually painless). Feeling of heaviness in the scrotum. Dull ache in lower abdomen and groin. Change in size or consistency of testicle.

Testicular Exam A testicular self-exam (TSE) should be performed about once a month. After a warm shower or bath when the skin of the scrotum is most relaxed. Examine one testicle at a time, repeating the process described here. Use both hands to examine each testicle. Hold the testicle between the fingers and thumbs of the hands.

Testicular Exam Roll the testicle between the thumbs and fingers with a gentle pressure that causes no pain or discomfort. Examine both testicles regularly, at least once a month. Feel for any pea-sized lumps or other irregularities at the front and sides of the testicles.  Learn the ropelike, tubular feel of the epididymis. If you feel a lump on the front or side of a testicle or if you feel pain or discomfort when performing the exam, contact your healthcare provider.

Seminiferous Tubules Tiny tubules located in the testicles, responsible for sperm production.

Epididymis The epididymis is a coiled segment of the spermatic ducts that serves to STORE, MATURE and transport sperm between the testis and the vas (the vas deferens).

Vas Deferens Long J shaped tube that carries sperm from the epididymis to the seminal vesicles. Site of Vasectomy Passage way for sperm only.

Vasectomy
