Flora is plant life; fauna refers to animals. Fauna derives from the name of a Roman goddess, but the handiest way to remember flora and fauna is that flora sounds like flowers, which are part of the plant world, and fauna sounds like fawn, and fawns are part of the animal kingdom. Definitions of fauna.
The testes and ovaries, or gonads, are perhaps the most familiar endocrine glands. In males, testes produce sperm and secrete the male sex hormone testosterone; in females, ovaries produce eggs and the female hormone estrogen.It is these hormones that determine secondary sex characteristics like muscle mass and facial hair. They also help to orchestrate sperm production, menstruation and pregnancy.he testes and ovaries, or gonads, are perhaps the most familiar endocrine glands.

Although follicle stimulating hormone is often associated with the female reproductive cycle, it is actually essential to growth, physical development, pubertal processes, and reproduction in males. Specifically, it stimulates the maturation of sperm cells prior to them becoming functional.estosterone levels control the secretion of GnRH. When T levels are low, the hypothalamus releases more GnRH, which increases FSH as well as luteinizing hormone (LH) secretion. This increase in FSH in turn increases T levels in a self-correcting feedback loop.
