Which of the following hormone is responsible for the development of secondary female characteristics and precipitate in control of menstrual cycle?

Estradiol

The hormone responsible for the development of secondary female characteristics and precipitate in control of the menstrual cycle is (2) Estradiol.

Estradiol is the most important estrogen in the human body. It is responsible for the development of secondary female characteristics, such as breast development, growth of pubic and underarm hair, and widening of the hips. Estradiol also plays a role in the menstrual cycle by stimulating the growth and development of the endometrium (the lining of the uterus).

The other options are incorrect:

(1) Adrenal cortex: The adrenal cortex produces a variety of hormones, including cortisol, aldosterone, and androgens. However, it does not produce estradiol.

(3) Androgens: Androgens are male sex hormones. They are responsible for the development of male secondary sex characteristics, such as facial hair, deepening of the voice, and muscle growth.

(4) Progesterone: Progesterone is another important hormone in the menstrual cycle. It is produced by the corpus luteum (a temporary endocrine structure that forms in the ovary after ovulation) and the placenta. Progesterone helps to prepare the endometrium for implantation of a fertilized egg.

Therefore, the correct answer is (2) Estradiol.
