Question

The reproductive cycle in females is regulated primarily by

Answer 1

The reproductive cycle in females is regulated primarily by HER HORMONES. Five hormones to be exact. These hormones are Estrogen, Progesterone, Luteinizing hormone (LH), follicle stimulating hormone (FSH), and gonadotropin releasing hormone.

Estrogen is from the ovaries. It helps regulate the menstrual cycle. It promotes the rapid growth of cell linings in the uterus to prepare for implantation resulting to pregnancy.

Progesterone is also from the ovaries. It is produced after ovulation and maintains the health of the lining within the uterus during pregnancy. If no pregnancy occurs, the progesterone level decrease and results to menses or monthly period.

Gonadotropin Releasing Hormone is secreted by the brain as a result of the hormonal changes that occur every month. It in turn stimulates the production of FSH and LH.

FSH stimulates the follicles inside the ovaries increase the amount of estrogen and progesterone produced in the first two weeks of the menstrual cycle.

The increase in estrogen level by FSH prompts the pituitary glands to release LH. Luteinizing hormone then signals the dominant follicle, made by FSH inside the ovaries, to release its eggs for possible fertilization.

Answer 2

The correct answer is estrogen and progesterone.

Step-by-step explanation:

The primary female sex hormone known as estrogen is accountable for the directive and development of the female reproductive system and secondary sex features. The other essential hormone apart from estrogen is progesterone, it takes part in pregnancy, menstrual cycle, and embryogenesis.

Both estrogen and progesterone work in synchronized manner to encourage reproductive activity of the female comprising the development and upkeep of the corpus luteum to withstand a fertilized ovum, development of the ovum, preparation of the breasts for lactation, and maintenance of pregnancy.
