In males which hormone stimulates Sertoli cells to produce androgen binding globulin (ABG)?
Correct answer
C
Rationale
Rationale for choice C (FSH) being correct:
1. FSH stimulates Sertoli cells in the testes.
2. Sertoli cells produce androgen binding globulin (ABG).
3. ABG binds to testosterone, regulating its availability.
4. FSH indirectly influences testosterone levels via ABG production.
Summary of incorrect choices:
A. LH stimulates Leydig cells to produce testosterone, not Sertoli cells.
B. GnRH regulates the release of FSH and LH but does not directly stimulate ABG production.
D. Oxytocin is not involved in the regulation of Sertoli cells or ABG production in males.
