Question

Which one of the following is the primary female sex hormone?
A. Insulin
B. Adrenaline
C. Estrogen
D. Thyroxine
E. None of these

Answer 1

There are two major types of female sex hormones namely estrogen and progesterone. Although testosterones are also considered as a male hormone, females also generate as well as need a small amount of this, too. Estrogen is a hormone in females bodies that is primarily responsible for the growth and regulation of the female reproductive system as well as secondary sexual characteristics.

Complete step by step answer: let consider all option one by one-
Option – A – Insulin is a peptide hormone elicited by beta cells of the pancreatic islets; it is deemed to be the central anabolic hormone of the human body. It restrains the metabolism of carbohydrates, fats as well as a protein by facilitating the absorption of glucose from the blood into liver, fat along skeletal muscle cells.
Option – B – Adrenaline is also known as epinephrine. It is a hormone and medication intake by humans. Adrenaline is generally manufactured by both the adrenal glands as well as a small number of neurons in the medulla oblongata, where it acts as a neurotransmitter pertained to in regulating visceral processes.
Option – C – Estrogen is also known as estrogen, is a classification of sex hormone accountable for the growth along with regulation of the female reproductive system and secondary sex traits. There are three major endogenous estrogens that have an estrogenic hormonal activity such as estrone, estradiol, and estriol.
Option – D – Thyroxine is the central hormone concealed into the bloodstream by the thyroid gland. It is the passive form and the maximum of it is transformed into an active known as triiodothyronine by organs like the liver and kidneys.
So, the correct answer to this question is option C - 'Estrogen'.

Note: Estrogen is the important female hormone. The lion’s share arrives from the ovaries, but small amounts are generated in the adrenal glands and fat cells. During pregnancy, the placenta also makes estrogen. Estrogen plays a huge role in reproductive as well as sexual development, including:
-Puberty
-Menstruation
-Pregnancy
-Menopause
