The primary benefit of pubic hair is its ability to reduce friction during sexual intercourse. The skin in the area around the genitals is very sensitive. Pubic hair can naturally reduce friction associated with the movements during sexual intercourse and other activities wherein chafing may occur.

They are found mainly in the cortex of stems and in leaves. The major function of sclerenchyma is support. Unlike collenchyma, mature cells of this tissue are generally dead and have thick walls containing lignin. Their size, shape, and structure vary greatly.

Functions of collenchyma: A mechanical tissue and provides mechanical support and elasticity to the stems of dicot plants. Cells possess chloroplast, then it is involved in manufacturing sugar and starch. Provides tensile strength and flexibility to the plant body.

Sclerenchyma cells have thick, lignified secondary walls, lack cell contents at maturity, and occur throughout all plant tissues. These features make sclerenchyma tissues hard, rigid, and somewhat brittle. Sclerenchyma cells can occur as aggregates within ground tissue (sclereids or stone cells or as elongated fibers.

The three most characteristic morphological features of collenchyma are (i) their axially elongated cells; (2) their cell wall thickenings; and (3) their living protoplasts (Fig. 1A–D).

Reducing friction The skin on your genital region is delicate. Pubic hair acts like a protective buffer, reducing friction during sex and other activities. Some sources even refer to pubic hair as a “dry lubricant.” That’s because it’s easier to rub hair against hair than it is to rub skin against skin.

Shaving is still the most popular way to get rid of pubic hair. But a new study from California found that women who shave their pubic hair regularly have a higher risk of contracting genital herpes, genital warts or the dreaded papillomaviruses.

If you choose to shave, It may be a good idea to wait until you’re 12 to 14 years old to shave your legs. Teens of this age are more likely to have the maturity to shave safely without hurting themselves. Skin cuts can result in bleeding and infection.

If you want to simply trim or style pubic hair, use a pair of scissors, electric razor or bikini trimmers to cut the pubic hair to the desired length. It helps protect your skin from irritation by avoiding re-shaving over any areas with longer hair and helps keep your razor blade sharper for longer.

Adrenarche is usually normal in girls who are at least 8 years old, and boys who are at least 9 years old. Even when pubic and underarm hair appear in children younger than this, it is still usually nothing to worry about, but your child does need to see their pediatrician for an exam.
