The "Estrogen" secretion is controlled by :

Options

A. FSH
B. LH
C. Progestrone
D. GTH

Answer

To determine which hormone controls the secretion of estrogen, we can follow these steps:

### Step 1: Identify the source of estrogen
Estrogen is primarily secreted by the ovaries, specifically from the ovarian follicles.

**Hint:** Remember that estrogen is a female sex hormone produced in the ovaries.

### Step 2: Understand the role of the pituitary gland
The secretion of estrogen is regulated by hormones released from the pituitary gland, which are known as gonadotropins.

**Hint:** Gonadotropins are hormones that stimulate the gonads (ovaries in females).

### Step 3: Identify the gonadotropins
The two main gonadotropins involved in regulating ovarian function are Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH).

**Hint:** Focus on the names of the hormones that stimulate the ovaries.

### Step 4: Determine the specific role of FSH
FSH, or Follicle Stimulating Hormone, specifically acts on the ovarian follicles, promoting their growth and stimulating the production of estrogen.

**Hint:** Consider which hormone directly influences the follicles to produce estrogen.

### Step 5: Evaluate other hormones
Luteinizing Hormone (LH) also plays a role in the menstrual cycle but is primarily involved in triggering ovulation and the production of progesterone, not directly in the secretion of estrogen.

**Hint:** Differentiate between the roles of FSH and LH in the menstrual cycle.

### Conclusion
The hormone that controls the secretion of estrogen is Follicle Stimulating Hormone (FSH).

**Final Answer:** FSH (Follicle Stimulating Hormone) controls the secretion of estrogen.
