Question:
Which layer in the Graafian follicle produces the hormone estrogen?
Which layer in the Graafian follicle produces the hormone estrogen?
Show Hint
Theca interna cells make androgens under LH, and granulosa cells convert them to oestrogen using aromatase.
Updated On: Nov 12, 2026
- membrana granulosa
- Theca externa
- Theca interna
- Cumulus oophorus
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept
A Graafian follicle has the theca externa, the theca interna and the membrana granulosa around the oocyte.
Step 2: Hormone synthesis
Under LH, theca interna cells make androgens from cholesterol.
Under FSH, the granulosa cells convert androgens to oestrogen (estradiol) using aromatase.
Step 3: Conclusion
The final production of oestrogen is by the membrana granulosa.
Final Answer:
The membrana granulosa produces oestrogen. \[ \boxed{\text{(A) }\text{membrana granulosa}} \]
