The temperature inside the body of a healthy man is . The scrotum keeps the testes to cooler than this.
- What is the highest temperature of the testes?
- What is the lowest temperature of the testes?
- Why would the sperm count of a man fall if he wore very tight clothes that hold the testes close to the body for many hours?
Need a reminder? The key ideaShow
A testis has about lobules, and each lobule holds to seminiferous tubules. The scrotum keeps the testes to below the temperature inside the body. Sperm route: seminiferous tubule, rete testis, vasa efferentia, epididymis, vas deferens, ejaculatory duct, urethra. Leydig cells make androgens. Sertoli cells feed the germ cells.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Given. Body temperature: . Drop: to .
Plan. Take the smallest and the largest drop away from .
Step 1. Highest. .
Step 2. Lowest. .
Step 3. Part (c). Sperms are made well only below the body temperature. Tight clothes hold the testes against the warm body, so the temperature rises and fewer sperms are made.
Answer: ; ; the heat lowers the making of sperms.
Check. Both values are below , as they must be.
