Like all other parts of human anatomy, human sexual and reproductive anatomy is full of diversity and difference. External and internal organs exist along a healthy spectrum of shape and size. Some of these organs serve reproductive functions, while others can provide pleasurable sensations.
An estimated 1 in 1,500 or 1 in 2,000 people are born with some variation in their external sexual anatomy noticeable enough to draw medical attention. Others are born with differences in internal sexual anatomy, hormone levels, or chromosomes. Many of these people are identified or identify as intersex. Despite this diversity, human sexual anatomy is currently classified in medical circles as either female or male.
Note on language: This page refers to “female” and “male” anatomy, although those with “female” anatomy might not identify as a woman and those with “male” anatomy might not identify as a man.
Some parts of human sexual anatomy change throughout life, due to puberty, menopause, childbirth, or other hormonal changes. People also choose to alter the form and function of their sexual anatomy by using hormones or undergoing surgical procedures.
Some of these alterations (like hormonal birth control, fertility treatments, or surgical sterilization) change the reproductive capacities of the human body. Others (like gender confirmation surgery) are undertaken with the goal of changing the shape or appearance of external organs. Many people who have gender confirmation surgery identify as transgender.
