Textbook Question
Chapter 28, Problem 3CAL
The physician reviews Luisa’s and Victor’s blood work. They discover that Victor has low levels of circulating luteinizing hormone (LH). How could this specifically affect Victor’s fertility?
- a. The interstitial cells would not be producing enough testosterone for spermatogenesis.
- b. The sustentacular cells are secreting too much inhibin.
- c. Spermatids are degenerating into primary spermatocytes.
- d. The sustentacular cells are unable to produce enough androgen-binding protein (ABP) for sperm development.
