The name of hormone secreted by the ovary, which facilitates growth of ovarian follicle is

Options

A. Progesterone
B. LH
C. FSH
D. Estradiol

Explanation

To answer the question regarding the hormone secreted by the ovary that facilitates the growth of ovarian follicles, we can follow these steps:

### Step 1: Identify the hormones related to the ovary
The question provides four options: progesterone, LH (luteinizing hormone), FSH (follicle-stimulating hormone), and estradiol. We need to determine which of these hormones is specifically involved in the growth of ovarian follicles.

### Step 2: Understand the function of each hormone
- **Progesterone**: This hormone is primarily involved in preparing the uterus for pregnancy and maintaining pregnancy. It does not play a direct role in the growth of ovarian follicles.
- **LH (Luteinizing Hormone)**: This hormone is involved in triggering ovulation and the development of the corpus luteum but is not primarily responsible for the growth of ovarian follicles.
- **FSH (Follicle-Stimulating Hormone)**: This hormone is specifically responsible for stimulating the growth and maturation of ovarian follicles in the ovaries.
- **Estradiol**: This is a form of estrogen that plays a role in the regulation of the menstrual cycle and the maintenance of the reproductive system but is not directly responsible for the initial growth of ovarian follicles.

### Step 3: Conclude with the correct answer
From the analysis above, it is clear that the hormone responsible for facilitating the growth of ovarian follicles is **FSH (Follicle-Stimulating Hormone)**.

### Final Answer:
The hormone secreted by the ovary that facilitates the growth of ovarian follicles is **FSH (Follicle-Stimulating Hormone)**.
