Question

What are the sources of estrogen and progesterone? Which of these is active during puberty and mention three of its effects on this period?

Answer 1

Hint: Hormone is the chemical that helps in the growth and development of the body. The hormone is directly secreted by the ductless gland known as the endocrine gland. The endocrine gland secretes hormones directly in the bloodstream and blood transport hormones to targeted organs.

Step by step answer:Estrogen and progesterone both are ovarian hormones. They both perform functions to maintain reproductive health and reproductive development. In the puberty phase, the hypothalamus releases the luteinizing hormone and follicle hormone through the pituitary gland. In males these hormone flow act on testes which results in the release of the male hormone androgen, that induces the spermatogenesis process. In females, these hormones target the ovary which results in the release of estrogen hormone. Estrogen hormone indices the ovulation process. After ovulation, the Graafian follicle is transformed into a corpus luteum that has an endocrine gland and releases progesterone hormone. Progesterone hormone is also known as the pregnancy hormone. It prepares the uterus for implantation of the blastocyst to the uterine walls and helps in the formation of the placenta.
So, at the time of puberty estrogen is more active. Estrogen is released by ovaries and progesterone by the corpus luteum. Estrogen functions during puberty.
1. Estrogen indices ovulation process
2. It helps in the formation of breast tissue.
3. Repair the endometrium layer of the uterus.
Additional Information: The rupture of the Graafian follicle and release of the ovule is called ovulation. The mature ovarian follicle is called Graafian follicle. After ovulation Grafton follicles transform into Corpus luteum.

Note: Estrogen promotes ovulation and progesterone promotes pregnancy. Low levels of progesterone result in degeneration of corpus luteum resulting in menstrual flow. Placenta also releases some amount of progesterone.
