Question

why there is hair in pubic region

Answer 1

Although fine vellus hair is present in the area in childhood, pubic hair is considered to be the heavier, longer and coarser hair that develops during puberty as an effect of rising levels of androgens in males and estrogens in females. Pubic hair is part of a person's body hair and a secondary sex characteristic. Many cultures regard pubic hair to be erotic, and in most cultures pubic hair is associated with genitalia, which both men and women are expected to keep covered at all times. In some cultures, it is the norm for pubic hair to be removed, especially of females, a practice which is regarded as part of personal hygiene. In other cultures, the exposure of pubic hair (for example, when wearing a swimsuit) may be regarded as unaesthetic or embarrassing, and is therefore trimmed or otherwise styled to avoid it being visible.
