Male Reproductive System (Exam 4)

Structure

Testes, Epididymis, Vas deferens, Seminal vesicles, Ejaculatory duct, Prostate gland, Penis

Testes Function

Located in the scrotum.Produce sperm, the male

sex cell.Secrete testosterone, hormone that develops and maintains maleness

Epididymis Function

Located on top of the testes. Storage for perm prior to ejaculation

Vas Deferens Function

Transports sperm from epididymis to the

ejaculatory duct

Seminal Vesicles

Helps produce a large portion of semen

Prostate Gland Function

Glandular structure beneath the urinary bladder , aids in the expulsion of sperm during ejaculation.

Penis Function

Produce and nurture male sex cells (sperm). Transport sperm to sites of fertilization.

Secrete hormones vital in development and maintenance of sexual characteristics.

Benign Prostatic Hyperplasia (B P H)

a common condition in older men where the prostate gland enlarges, putting pressure on the urethra and causing urinary problems

Benign Prostatic Hyperplasia (B P H) Signs and Symptoms

Over proliferation of cells within the inner portion of the prostate.

Common in men older than 50 years of age, with increased incidence with age. Clinically significant if the enlarging, hyperplastic portion of the prostate obstructs urinary outflow. Urinary obstruction includes difficulty in initiating urination or in completely emptying the bladder.

Benign Prostatic Hyperplasia (B P H) Treatment

Depends on the severity of symptoms of the urinary system. Symptomatic treatment may include prostatic massage, catheterization, and avoiding caffeine and alcohol. Various medications to shrink the prostate or relax the muscles in the prostate.

Surgical interventions to remove obstructing tissue include:

uLaser surgery.

uTransurethral resection of the prostate (T U R P).

Prostate Cancer

a type of cancer that develops in the prostate gland

Prostate Cancer Signs and Symptoms

Malignant neoplasm of prostatic tissue. Majority are classified as adenocarcinomas. Most men with prostate cancer are asymptomatic on diagnosis. Tends to metastasize, often spreading to the bones of the spine or pelvis before it is detected. Disease is rare before age 50 years.

Prostate Cancer Treatment

Course of treatment depends on the stage of the disease and the patient’s physical condition and age.

Digital rectal examination

Examination of the prostate by finger palpation through the anal canal and rectum. Used to detect prostate enlargement .Should be done yearly in men older than age 40 years.

Transurethral resection of prostate (T U R P):

Relieves obstruction caused by prostatic hyperplasia. Prostatic tissue is chipped away and flushed out.

Vasectomy:

Sterilization procedure. Bilateral ligation of vas deferens to prevent passage of sperm. Commonly performed at outpatient clinic.
