Graffian follicles (granulosa cells) , produced progesterone and inhibin (small amount) when fertilization not occurs then inhibin work on hypothalamus and produced negative feedback then inhibits the secretions of FSH and FSH ultimately inhibits LH

**Inhibin and its Role in Reproduction**
Inhibin is a hormone that plays a crucial role in the regulation of reproductive processes in both males and females. It is primarily produced by certain cells in the ovaries and testes, specifically the granulosa cells in the ovary and nurse cells in the testes.
**Inhibin and its Effects**
Inhibin acts as a negative feedback regulator of the pituitary gland, which controls the secretion of several reproductive hormones, including follicle-stimulating hormone (FSH), luteinizing hormone (LH), and prolactin. Its main function is to inhibit the secretion of FSH from the pituitary gland, thereby reducing the stimulation of follicular development in the ovary and the production of estrogen.
**The Correct Statement about Inhibin**
The correct statement about inhibin is option 'C', which states that inhibin is produced by granulosa cells in the ovary and inhibits the secretion of FSH. This statement accurately describes the function and source of inhibin in the female reproductive system.
**Explanation of Option 'C'**
Granulosa cells are found within the ovarian follicles and play a crucial role in the development and maturation of eggs. They produce inhibin in response to increasing levels of estrogen. Inhibin then acts on the pituitary gland, specifically the gonadotroph cells, to inhibit the secretion of FSH. This negative feedback mechanism helps to regulate the menstrual cycle and maintain a balance of reproductive hormones.
By inhibiting FSH secretion, inhibin helps to prevent the excessive development of multiple follicles and ensures that only one dominant follicle matures during each menstrual cycle. This ensures the production of a single ovum and helps to regulate the timing of ovulation.
**Conclusion**
Inhibin is an important hormone in the regulation of reproductive processes. It is produced by granulosa cells in the ovary and inhibits the secretion of FSH from the pituitary gland. This ensures proper follicular development, ovulation, and maintenance of reproductive hormone balance in females.
