Why don’t Women Have Beards?

            All mammals including man have some hair on tier bodies. In some mammals, hair covers the whole body, but in humans, hair grows only in certain parts.

Women do not have beards due to the absence of androgen

            Hair preserves the body warmth and protects the skin. It also helps us in realizing the sense of touch. The hair on your eyebrows and eyelashes; and in the ear and nose help protect these organs from dust, impurities and insects.

            So why it is that man have beards and women done not? When a child is born, he has only fur-like hair one the body, and as he grows, the hair becomes coarser. Boys and girls reach puberty at the age of 12 to 15 years and growth of sex glands at this age is faster. In men, the sex glands, produce a group of hormones known as androgens, and in women, they produce estrogens.

            The function of androgen is to regulate secondary sex male features, such as the growth of facial and chest hair ad deepening of the male voice at puberty. The function of the estrogens is to regulate secondary female sexual features, such as the change in the size of breasts, growth of public hair and onset of the menstrual cycle. There are various other changes in men and women brought about by these hormones. For example, the female body becomes soft and tender, whereas the male body becomes hard and strong. A special group of hormones called the progesterone that is responsible for the regulation of pregnancy in women. Therefore, women do not have beards primarily due to the absence of androgen.

How is Baby Born?

            After the menstrual cycle is over, during the first two weeks and egg develops in an ovary and is released in to the womb. If during this period, man and woman perform intercourse, the egg gets fertilized. The fertilized egg begins to grow into a baby.

The Mother's Womb

            After an egg is fertilized, the development takes place at a fast rate and it quickly develops into an embryo. The mother’s body keeps the developing embryo supplied with food and oxygen. The major organs of the embryo, such as heart and brain appear soon. After about six weeks, the limbs, eyes and ears develop.

            After eight weeks, the baby now called a fetus has almost all its organs and tissue, including its nervous system, muscles and skeleton. During the next seven months, the embryo continues to grow as a baby and is ready to be born after nine months in the womb (uterus).

            When a baby is ready to be born, the mother begins to experience labor pains, i.e., painful contractions of the uterus. The uterus muscles push the baby downwards and the neck of the womb starts to open. Eventually, the baby emerges out into the world. Normally, it is gently slapped on the buttocks, or it is lowered alternately into basins containing warm and cool water to make it cry; it then starts breathing and the umbilical cord joining it to the other is cut by the doctor.
