D. Lowers trasport protein
Correct answer: D. Lowers trasport protein
Explanation:-
Question: All the following are functions of estrogen EXCEPT:
Since options are not provided in your message, I will describe common functions of estrogen and then mention functions that are NOT done by estrogen (i.e., the correct answer type).
Functions of Estrogen
Estrogen is a female sex hormone primarily produced by the ovaries. Its major functions include:
1. Development of secondary sexual characteristics
• Breast development
• Widening of hips
• Growth of pubic and axillary hair
2. Growth and development of the endometrium
• Causes proliferation (thickening) of the uterus lining
3. Regulates menstrual cycle
• Works with progesterone to prepare the uterus for pregnancy
4. Stimulates growth of ovarian follicles
5. Maintains bone density
• Prevents osteoporosis by reducing bone resorption
6. Increases fat deposition
• Especially on hips and thighs
7. Improves skin elasticity and vascularization
8. Maintains female libido and mood
Functions NOT performed by estrogen (EXCEPT answers)
If the question requires choosing the exception, typical options that are NOT functions of estrogen include:
Maintenance of pregnancy
• Mainly done by progesterone, not estrogen
Secretory changes in endometrium
Done by progesterone, not estrogen
Inhibition of FSH
• Mainly done by inhibin and progesterone
Milk production
Done by prolactin
Correct type of answer (most common)
The correct answer is usually:
Secretory changes in endometrium
(because this is the function of progesterone, not estrogen)
Other options details
Here is the explanation of all the options:
A. Cause breast growth
• This refers to hormones (mainly estrogen and progesterone) that stimulate the development of breast tissue.
• During puberty, pregnancy, and the menstrual cycle, these hormones cause growth of breast ducts and fat deposition.
• Also contributes to the development of secondary sexual characteristics in females.
B. Increase follicle development
• This refers to Follicle Stimulating Hormone (FSH), which stimulates the growth and maturation of ovarian follicles in the ovary.
• Each menstrual cycle, FSH helps one follicle become dominant and prepared for ovulation.
• Essential for egg development and fertility.
C. Cause inhibition of FSH
• This is usually caused by estrogen and inhibin, which provide feedback to the pituitary gland to reduce FSH secretion.
• This prevents multiple follicles from maturing at the same time.
• Helps regulate the menstrual cycle and hormone balance.
D. Lowers transport protein
• Some hormones, particularly androgens like testosterone, can reduce the level of transport proteins such as sex hormone-binding globulin (SHBG).
• Lower SHBG means more free (active) hormone in the bloodstream.
• This effect can influence reproductive functions, metabolism, and secondary sexual characteristics.
