6.1 Role of Hormones in Male and Female Sexual Development
Hormones
Explanation level
Introduction
The reproductive system is unique because it becomes functional at a certain age after birth, called puberty. Sexual development in both males and females is controlled by hormones. These chemical messengers are produced by endocrine glands and travel in the blood to target cells. This topic explains the role of hormones in male and female sexual development.
Definition
Hormones are chemical messengers that are produced and released by endocrine glands into the blood. They interact with their target cells due to the presence of specific receptors on the target cells.
Puberty is the stage of development when the reproductive system becomes functional.
Main Idea
Unlike other organ systems, the reproductive system is unique because it becomes functional at a certain age after birth, called puberty. Sexual development that leads to puberty in both males and females is controlled by hormones.
The hormones are chemical messengers that are produced and released by endocrine glands in blood. The hormones interact with their target cells due to the presence of specific receptors on the target cells.
Core Concept
Hormones in Male and Female Sexual Development
| Gender | Hormones | Main Functions |
|---|---|---|
| Male | Testosterone | Development of male reproductive organs, sperm maturation, secondary sexual characteristics |
| Male | Follicle stimulating hormone (FSH) | Supports development of sperm cells, regulates early stages of spermatogenesis |
| Female | Estrogen | Development of female reproductive organs, secondary sexual characteristics |
| Female | Follicle stimulating hormone (FSH) | Development of ovarian follicles, oogenesis, estrogen production |
| Female | Luteinizing hormone (LH) | Ovulation, formation of corpus luteum, progesterone production |
| Female | Progesterone | Prepares body for pregnancy, thickens uterine lining |
