Question 1

The term "gender identity" refers to a person's

Accepted Answer

Gender identity refers to a person's subjective sense of themselves as male, female, both, or neither. It is not related to sexual preference or hormones levels, and it goes beyond sexual behavior or interest.

Question 2

If a genetically male fetus is exposed to high levels of both estrogen and testosterone during early development,its sexual anatomy will develop an appearance similar to

Accepted Answer

The answer of If a genetically male fetus is exposed...

Question 3

Under what circumstances might a genetically female (XX)fetus develop a sexual anatomy that partly resembles that of a genetic male (XY)?

Accepted Answer

If a genetically female (XX) fetus is exposed to more testosterone than normal for a female fetus during development, her sexual anatomy may partly resemble that of a genetic male (XY). Testosterone is a male sex hormone that is responsible for the development of male genitalia, and the exposure to higher levels of testosterone can cause the clitoris to enlarge and extend into a structure resembling a penis.

Question 4

An article in the latest issue of the Gullible Inquirer claims that a person was born with both a penis and a clitoris.Why is that impossible?

Accepted Answer

Both the penis and clitoris develop from the same structure in the fetus called the genital tubercle. However, during fetal development, the presence of certain hormones like testosterone can cause the genital tubercle to grow into a penis, while the absence of these hormones or presence of other hormones like estrogen can result in the growth of a clitoris. Therefore, it is not impossible to have both structures, as they originate from the same tissue.

Question 5

Why is it impossible for a person to have a complete set of both male genitals and female genitals?

Accepted Answer

The development of both male and female genitals starts from the same structure, called the genital tubercle or the precursor to genitalia. As the fetus develops, the presence or absence of certain hormones determines the differentiation of the genital tubercle into either male or female genitalia. Therefore, it is not possible for a fetus to form both male and female genitals from the same structure.

Question 6

Which of the following never occurs?

Accepted Answer

An individual with a complete set of both male and female genitals is physiologically impossible. While intersex conditions exist where individuals may have ambiguous genitalia or a mix of male and female physical characteristics, having a complete set of both male and female genitals is not possible due to the different structures and functions of male and female reproductive systems.

Question 7

Whether a child develops masculine-looking genitals or feminine-looking genitals depends mostly on

Accepted Answer

The development of masculine or feminine genitals in a child is determined by the level of testosterone during early development. The presence of testosterone promotes the development of male genitals, while its absence allows for the development of female genitals. Estrogen also plays a role in genital development, but it is secondary to testosterone.

Question 8

One small structure that is present at the fetal stage for both males and females develops into a penis in males.What happens to that structure in females?

Accepted Answer

The small structure present at the fetal stage in both males and females is called the genital tubercle. In males, it develops into the penis, while in females it develops into the clitoris.

Question 9

Which of the following infants would be most likely to develop a sexual anatomy that is intermediate between male and female?

Accepted Answer

Exposure to high levels of testosterone during prenatal development can lead to virilization of the external genitalia in genetic females, resulting in an intermediate or ambiguous sexual anatomy.

Question 10

A genetic female who is exposed to elevated testosterone levels during early development will develop in what way?

Accepted Answer

Exposure to elevated testosterone levels during early development can lead to partial masculinization of physical traits in genetic females. This can include changes in body shape, musculature, and bone structure. However, it is unlikely to result in completely male or female physical characteristics.

Question 11

A genetic female exposed to more than the usual amount of testosterone develops an external appearance that is __________.A genetic male exposed to more than the usual amount of estrogen develops an external appearance that is __________.

Accepted Answer

A genetic female exposed to more than the usual amount of testosterone will develop an external appearance that is partly masculinized, while a genetic male exposed to more than the usual amount of estrogen will develop an external appearance that is normal male. This is because testosterone is responsible for the development of male sex characteristics, while estrogen is responsible for the development of female sex characteristics.

Question 12

What happens to the sexual development of a genetically male fetus that is exposed to more than the usual amount of estrogen during early development (more than normal for a male,though less than normal for a female)?

Accepted Answer

The answer of What happens to the sexual development of...

Question 13

Someone who regards himself as a man and who prefers male sexual partners has a __________ gender identity.

Accepted Answer

The person identifies as male and prefers male sexual partners, indicating a male gender identity. Option A (mixed) does not accurately describe a specific gender identity, and option B (homosexual) describes sexual attraction rather than gender identity. Option D (female) does not apply since the person identifies as male.

Question 14

What happens to the sexual development of a fetus (genes not specified)that is exposed to lower than the normal amounts of both testosterone and estrogen during early development?

Accepted Answer

Lower than normal amounts of both testosterone and estrogen during early development typically result in the development of a more or less normal female appearance. Without sufficient levels of these hormones, the fetus will not undergo the anatomical changes that would lead to the development of male reproductive organs.

Question 15

If a genetically female human fetus were exposed to high but equal levels of both testosterone and estrogen,its sexual anatomy at birth would appear

Accepted Answer

Exposure to high levels of both testosterone and estrogen would partially masculinize the sexual anatomy of the genetically female fetus, resulting in an ambiguous or intersex external genitalia at birth.

Question 16

A genetic male who is exposed to elevated estrogen levels during early development will develop in what way?

Accepted Answer

The answer of A genetic male who is exposed to...

Question 17

If a fetus is exposed to low levels of both estrogen and testosterone during early development,its sexual anatomy will develop appearing

Accepted Answer

In human development, the default pathway of sexual differentiation is female. If a fetus is exposed to low levels of both estrogen and testosterone, it will develop anatomy that appears similar to that of a female, as the development of male genitalia and secondary sexual characteristics requires higher levels of testosterone.

Question 18

What happens to the sexual development of a genetically female fetus that is exposed to more than the normal amount of testosterone during early development (more than normal for a female,though less than normal for a male)?

Accepted Answer

Exposure to excess testosterone during fetal development can result in an appearance that is intermediate between typical male and female patterns, with some male features and some female features. This is known as partial masculinization or virilization.

Question 19

Which of the following fetuses is most likely to develop a sexual anatomy that appears intermediate between that of a normal male and that of a normal female?

Accepted Answer

The development of male and female sexual anatomy relies heavily on the presence or absence of certain hormones during prenatal development. In the case of an individual with an intermediate anatomy, it is likely that there was exposure to hormones that interfered with the typical differentiation of the reproductive system. Of the options provided, the genetic female who was exposed to more testosterone than normal is the most likely to develop an intermediate anatomy because testosterone is the hormone that typically masculinizes the reproductive system. Therefore, excessive exposure to testosterone in a female fetus could lead to the development of male-like genitalia.

Question 20

The drug sildenafil (Viagra)increases sexual arousal by altering

Accepted Answer

Sildenafil works by increasing blood flow to the penis, which helps to improve erectile function and sexual arousal.
