Answer 1

Hint: Hormones in our body have a vital role in the growth and development and also reproduction. There are a set of hormones for regulating reproduction mechanisms. Both the pre and post-delivery mechanism are also regulated by the hormones.

Complete answer:
Various hormones are acting in our body which carries out some specific metabolism. Some of the reproductive hormones are – oxytocin, prolactin, luteinizing hormone, progesterone etc. They are responsible for the libido of the male and females.

What is LTH?
It is the luteotropic hormone or also called luteotropin. It is the peptide hormone which is responsible for the secretion of milk in the mammary glands. The babies after their birth need their mother's milk as feed to grow and have immunity. This hormone initiates the production of milk after the delivery of the child. It is secreted by the pituitary gland.

Let us see what can be the other names of the LTH.
> Option A: Lactogenic hormone: It is the hormone which initiates the secretion of milk from the breasts and also helps in breast development. It is the other name of prolactin. It is secreted by the anterior lobe of the hypophysis in the brain.

> Option B: Prolactin: It is one of the most important hormones in the female’s body as it regulates the breast size during and after pregnancy to feed the child with the milk. The level of prolactin will increase variably during pregnancy.

> Option C: Mammotropic hormone: The word itself defines its work. Mammo means mammary glands thus it helps the mammary glands to release the milk after the childbirth. The period is called the lactating period when the mother produces milk to feed the child.

Hence, The correct answer is option (D).

Note: The increased amount of prolactin alters the production of estrogen and progesterone. This can stop the ovulation. In a non-pregnant lady, the prolactin increase will decrease the lipid metabolism. When we are stressed, there is an increase in the prolactin level.
