Sexual characteristics refer to the physical attributes and features that are typically associated with either males or females and relate to their reproductive functions and roles in sexual reproduction. These characteristics are primarily determined by an individual's biological sex, which is determined by their chromosomal, hormonal, and anatomical characteristics.
In males, sexual characteristics include the presence of external genitalia such as the penis and scrotum, as well as internal reproductive organs such as the testes and prostate gland. Secondary sexual characteristics in males typically manifest during puberty and include the growth of facial and body hair, deepening of the voice, and increased muscle mass.
In females, sexual characteristics involve the presence of external genitalia such as the clitoris, labia, and vagina, along with internal reproductive organs such as the ovaries, uterus, and fallopian tubes. Secondary sexual characteristics in females also develop during puberty and may include the development of breasts, the growth of pubic and underarm hair, widened hips, and a more rounded body shape.
These sexual characteristics play significant roles in sexual reproduction, as they enable the production, delivery, and reception of gametes (sperm and eggs) necessary for fertilization. Understanding sexual characteristics is crucial for comprehending the physiological and anatomical differences between males and females, as well as promoting scientific research, medical treatments, and healthcare interventions specific to each sex.
The word "sexual" is derived from the Latin word "sexus", which means "gender" or "sex". It is related to the Latin "secare", meaning "to divide", and "secus", meaning "to cut". The word "characteristic" comes from the Greek word "kharaktēr", which means "distinctive mark" or "distinctive feature". Therefore, the etymology of "sexual characteristic" can be understood as the unique features or attributes specific to a particular gender or sex.
