Description

CHAPTER 9 ASSIGNMENT Discussion Questions: 1. Discuss 4 of the disorders that can occur in the male reproductive system?  Carcinoma of the testes (testicular cancer) -malignamt tumor of the testicles. Most commonly occur in men between the ages of 15-35. Most common tumor is a seminoma.  Hydrocele- Sac of clear fluid in the scrotum. Can be congenital or occur as a response to an infection or tumor. May resolve on its own, but if not procedure is required. Either the sac is aspirated with a needle and syringe or a hydrocelectomy, where the sac is surgically removed through an incision in the scrotum.  Testicular torsion- Twisting of the spermatic cord. This twisting results in cut off blood supply to the testis. Occurs most frequently in childhood. If surgical correction is not preformed within hours of onset, may result in loss of testis.  Carcinoma of the prostate (prostate cancer)- Malignant tumor of the prostate gland (adenocarcinoma). Most commonly occurs in men over 50. Prostatespecific antigen (PSA) test can detect early, however, a digital rectal examination (DRE) can detect the tumor at a later stage. 2. Describe the role of testosterone. Testosterone is a hormone secreted by the male reproductive system that plays a vital role in the production of male bodily characteristics such as facial hair and a deep voice. It also aids in the correct development of the testes as well as other organs such as the prostate gland and seminal vesicles that secrete fluids to ensure lubrication and viability of the sperm.

3. Victor, a 25-year-old man, has had surgery to remove one of his testicles due to seminoma. Can he still father a child? Why or why not? After having a orchiectomy, Victor would still be able to father a child because his remaining testis would still produce sperm normally.

He had a TURP 1 year ago for presumed prostatic hyperplasia, but tissue fragments examined by a pathologist revealed a poorly differentiated adenocarcinoma. He received local irradiation to the prostate; however, PSA levels increased to 10 (normal is less than 4). A bone scan showed bony metastases. Bilateral orchiectomy was advised, but refused.
