What is the role of hormone in male and female reproductive system?

Testosterone 
Chemical messengers, or are also called “hormones” are chemicals in the body that sends signal on a certain gland organ to enable or stimulate their supposed function. An example is a testosterone, testosterone is a hormone mainly produced by the testes in males. Though this gland is also present in females, amount varies due to its chemical properties which affect males in their physical and psychological make-up. Testosterone is also responsible for spermatogenesis in males, in which this process in simpler terms is to the production of sperm cells –males.
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.
