Question

Which of the following is not a function of progesterone in the female reproductive system?

A) expression of secondary sexual characteristics, such as enlarged breasts

B) stimulation of milk production in the breasts

C) regulation and preparation of the endometrial lining of the uterus for potential pregnancy

D) inhibition of contractions of the uterus as the ovum is released

Answer 1

Progesterone is not responsible for the expression of secondary sexual characteristics such as enlarged breasts; this is a function of estrogens like estradiol. Progesterone mainly prepares the endometrium for pregnancy, regulates the menstrual cycle, and suppresses uterine contractions.

Step-by-step explanation:

The correct answer to the question of which of the following is not a function of progesterone in the female reproductive system is A) expression of secondary sexual characteristics, such as enlarged breasts. This is because the development of secondary sexual characteristics in females is primarily attributed to estrogens, not progesterone. Hormones like estradiol are responsible for the development of characteristics like breast tissue and body shape changes. Progesterone's main functions include preparation of the endometrium for potential pregnancy (C), regulation of the menstrual cycle, and suppression of uterine contractions to maintain a pregnancy (D). While progesterone does play a role in the female reproductive system by assisting in endometrial regrowth and inhibiting FSH and LH release, it is not responsible for the initial appearance of secondary sex characteristics which is typically influenced by estrogens.

Answer 2

The function not associated with progesterone is the expression of secondary sexual characteristics, such as enlarged breasts. Estrogens, not progesterone, play a key role in developing secondary sexual characteristics in females.

So the correct answer is Option A

Step-by-step explanation:

The option that is not a function of progesterone in the female reproductive system is 'A) expression of secondary sexual characteristics, such as enlarged breasts'. The hormone progesterone mainly functions in the maturation and maintenance of reproductive organs, preparation of the uterus for pregnancy, regulation of the menstrual cycle, and commonly inhibits uterine contractions to protect the fetus.

It is actually estrogen that are primarily responsible for the development of secondary sexual characteristics in females, such as breast development and the distribution of body fat. Moreover, progesterone plays a crucial role in suppressing FSH and LH, thereby inhibiting the release of new ovarian follicles and maintaining pregnancy by suppressing uterine contractility.

the correct answer is Option A
