Part I. Clinical Applications
1. A man swam is a cold lake for an hour and then noticed that his scrotum was shrunken and
wrinkled. His first thought was that he had lost his testicles. What had really happened?
2. A 38-year-old male is upset about his low sperm count and visits a “practioner” who commonly
advertises his miracle cures for sterility. In fact, the practitioner is a quack who treats
conditions of low sperm count with mega-doses of testosterone. Although his patients
experience a huge surge in libido, their sperm count is even lower after hormone treatment.
Explain why.
3. What is an average volume of semen ejaculated and an average sperm count? What sperm
count is considered to be infertile?
4. How does an intrauterine device (IUD) contraceptive prevent pregnancy?
5. Surgical sterilization is a procedure that renders an individual incapable or reproduction.
Explain how is this procedure done in males and females?
