The term "sex organ" originates from the Latin "organum" which means "instrument" and the Old French "sexe" meaning "gender" or "sex".
Types of Sex Organs
Sex organs are typically differentiated into male sex organs and female sex organs, based on the type of gametes they produce:
- Male sex organs: The primary male sex organ is the testis, which produces sperm. Other male sex organs include the penis, vas deferens, prostate gland, and seminal vesicles.
- Female sex organs: The primary female sex organ is the ovary, which produces eggs (ova). Other female sex organs include the vagina, uterus, fallopian tubes, and mammary glands.
