sexo

Sexo refers to the biological attributes that define humans as male, female, or intersex. In humans, sex is usually associated with chromosomes, gonads, and hormone profiles, but there is natural variation. The concept is distinct from gender, which encompasses social roles, identities, and expressions; some people have sex characteristics that do not fit typical definitions of male or female (intersex), reflecting human diversity.

Reproduction typically involves gametes: sperm and egg. Fertilization can result in pregnancy, but sexual activity also serves bonding, recreation, and social functions. Not all sexual activity is linked to reproduction, and some people conceive with assisted methods.

Sexual health includes physical and emotional well-being in relation to sexuality. Important components are consent, safe sex practices, protection against sexually transmitted infections, and access to contraception and sexual health services. Regular medical care and open communication with partners support healthy outcomes.

Education and rights: Comprehensive sex education, tailored to developmental level and cultural context, helps individuals make informed decisions about relationships, contraception, consent, and reproductive rights. Legal frameworks often address age of consent, privacy, coercion, and protection against exploitation; respect for autonomy and dignity is central to ethical practice in all sexual matters.

Cultural perspectives: Attitudes toward sex vary across societies and over time. Ongoing research and dialogue promote sexual health, reduce stigma, and support equal rights for people of all sexes and sexual orientations.
