Answer

Development of secondary sexual characters in females are controlled by Oestrogen

Secondary sexual characteristics refer to the physical features that differentiate males and females and develop during puberty. These characteristics include breast development, widening of hips, increased body fat distribution, and changes in body hair and skin.

Oestrogen, a hormone mainly produced by the ovaries, plays a crucial role in the development of secondary sexual characters in females. Here's a detailed explanation of how oestrogen controls the development of these characteristics:

1. Breast development:
- Oestrogen stimulates the growth of breast tissue during puberty.
- It promotes the deposition of fat in the breast region, causing them to increase in size and become more rounded.
- Oestrogen also promotes the development of mammary glands, which are responsible for milk production in females.

2. Widening of hips:
- Oestrogen influences the distribution of body fat, causing it to accumulate in the hips and thighs.
- This results in a wider hip structure, giving females a characteristic feminine silhouette.

3. Changes in body hair:
- Oestrogen indirectly affects body hair growth by regulating the levels of another hormone called testosterone.
- Testosterone is responsible for the growth of body hair, including pubic hair and underarm hair.
- Oestrogen helps maintain a balance between testosterone and other hormones, resulting in the development of fine and less dense hair in females compared to males.

4. Skin changes:
- Oestrogen contributes to the development of softer and smoother skin in females.
- It increases collagen production, which improves skin elasticity and reduces the appearance of wrinkles.
- Oestrogen also influences the production of sebum, an oily substance that keeps the skin hydrated and prevents dryness.

Overall, oestrogen plays a vital role in the development of secondary sexual characteristics in females. It influences breast development, widening of hips, distribution of body fat, body hair growth, and skin changes. These changes occur during puberty under the control of oestrogen, helping to differentiate females from males and contribute to their reproductive function.
