Female: Meaning, Biological Sex, Gender, and Usage

For example:

• A female bird may lay eggs.
• A female patient may have ovaries and a uterus, although not every female person has the same anatomy.
• The adjective female can appear before a noun, as in female athlete.
• In everyday conversation, woman is often better than calling an adult person a female.
• A person’s gender identity cannot always be known from the word female alone.

The exact meaning depends on whether the subject is biology, medicine, grammar, identity, statistics, or ordinary social communication.

Female as an Adjective

As an adjective, female describes a noun:

• a female patient;
• a female animal;
• a female reproductive organ;
• a female athlete;
• a female character.

The adjective does not change in plural sentences:

• one female student;
• several female students.

Female as a Noun

As a noun, female may refer to a female organism:

• The female laid several eggs.
• The study included ten males and twelve females.
• The female remained close to the nest.

This noun use is common in biology, veterinary science, research, and statistics.

When referring to adult humans in everyday English, using female as a noun can sound clinical, impersonal, or disrespectful:

• More natural: The woman spoke first.
• More clinical: The female spoke first.

The preferred wording depends on context, but woman is generally better for ordinary human reference.

Female may refer to:

• biological sex;
• a reproductive category;
• a human, animal, or plant;
• a classification in medicine or research.

Woman usually refers to:

• an adult human gender identity;
• an adult person socially recognized or identifying as a woman.

A transgender woman is a woman, even if some medical records describe her sex assigned at birth differently. A female child is usually called a girl, while an adult woman is not normally called a girl in formal adult contexts.

Feminine refers to qualities, appearance, behavior, or expression culturally associated with women or girls.

Compare:

• A female person may dress in a masculine style.
• A male person may have a feminine appearance.
• A nonbinary person may express femininity.
• Femininity does not prove that someone is female.

Biological classification and gender expression are therefore different.

The term female may sometimes appear in gender identity descriptions, but many people prefer words such as:

• woman;
• girl;
• transgender woman;
• cisgender woman;
• nonbinary person.

A person may identify as a woman without describing themselves as biologically female. Others may comfortably use both female and woman. Respectful language follows the person’s own identity and the purpose of the discussion.

In humans, reproductive structures commonly associated with female development may include:

• ovaries;
• fallopian tubes;
• uterus;
• cervix;
• vagina;
• vulva.

However, not every female person has all these structures. Anatomy may differ because of natural variation, intersex traits, surgery, age, congenital conditions, or medical treatment.

Biological sex is assessed through several characteristics rather than one body part alone.

• chromosomes;
• reproductive organs;
• genital anatomy;
• hormones;
• secondary sex characteristics;
• reproductive function.

Many females have XX chromosomes, but chromosomes and physical development do not always follow one simple pattern. Some people have intersex variations involving chromosomes, hormones, gonads, or anatomy.

For this reason, statements such as “all females have a uterus” or “all females menstruate” are inaccurate.

• produce eggs;
• menstruate;
• become pregnant;
• give birth;
• breastfeed or lactate.

These abilities vary. A female person may be infertile, postmenopausal, born without a particular organ, or have undergone surgery. Reproductive capacity does not determine whether someone is fully female or fully a woman.

A person’s worth and identity should not be measured by fertility, menstruation, pregnancy, or motherhood.

AFAB does not necessarily describe the person’s current gender identity.

An AFAB person may later identify as:

• a woman;
• a transgender man;
• nonbinary;
• genderfluid;
• another gender.

The phrase is useful when birth classification is specifically relevant, but it should not replace a person’s present identity unnecessarily.

• reproductive anatomy;
• sex-based health patterns;
• medication studies;
• laboratory reference ranges;
• pregnancy;
• gynecological care.

Accurate medical care should still avoid assumptions. For example, not every woman has a cervix, and not every person with a cervix identifies as a woman.

Clear healthcare language may need to refer directly to the relevant anatomy, such as:

• people with ovaries;
• patients who can become pregnant;
• individuals with a cervix;
• people using estrogen therapy.

• female reproductive anatomy;
• female animal;
• female participant;
• female hormone pattern.

Use woman when discussing an adult human person socially:

• a woman entered the room;
• women’s rights;
• a group of women;
• she is a woman.

Avoid using female in a way that reduces a person to biology or sounds dehumanizing, especially when men is used in the same sentence instead of males.

For example:

• Unbalanced: Men and females attended the event.
• Better: Men and women attended the event.
• Technical: Male and female participants were included.

Every female has the same reproductive anatomy.
Bodies differ because of age, natural variation, surgery, health conditions, and intersex traits.

Every female can become pregnant.
Pregnancy capacity varies and is not required for female identity.

Feminine means female.
Femininity is a style or form of expression, not a biological category.

A transgender woman is not a woman.
A transgender woman is a woman; birth classification and current gender identity are distinct concepts.

Using female as a noun is always neutral.
It can sound clinical or disrespectful when woman would be more natural.

1. Female is commonly used as both an adjective and a noun.
2. The female bird remained near the nest.
3. The study included both male and female participants.
4. A female person does not necessarily have every organ associated with female reproduction.
5. The word female is often appropriate in biological and medical descriptions.
6. In everyday conversation, woman may sound more respectful than female as a noun.
7. Being female is not the same as expressing femininity.
8. A person assigned female at birth may later identify as a man or as nonbinary.
9. Not every female menstruates, becomes pregnant, or gives birth.
10. The meaning of female depends on whether the context concerns biology, gender, medicine, or social identity.

However, being female does not determine a person’s sexual orientation, sexual behavior, gender expression, reproductive ability, or relationship preferences. Female people may be heterosexual, lesbian, bisexual, asexual, queer, or have another orientation.

Clear sexual-health language distinguishes female sex classification from womanhood, femininity, anatomy, fertility, and gender identity. Respectful communication uses the term only when it is relevant and avoids assuming that all female people have the same bodies or experiences.
