 The Male Gonads are located behind the penis in the skin pouch called the scrotum.

 Male gonads produce the sex hormones in the body  Male sex hormones are called testosterone  They stimulate the formation of sperms in the seminiferous tubules.

 Develops reproductive tissues  Increases muscle size, bone mass, and body hair

 It sustains spermatogenesis  maintains muscle bulk  maintains secondary sex characteristics  aids in erectile function.

 Clomiphene citrate stimulates gonadotropin production  In the adult it suppresses urinary follicle stimulating hormone (FSH) excretion and plasma testosterone concentration in prepubertal children  Such results indicate that feedback between gonad and hypothalamus is operative and highly sensitive in prepubertal humans.

 The gonads are responsible for the production of steroid hormones, such as testosterone  However, calcitonin inhibits testosterone

 Hypogonadism is a medical term which describes a diminished functional activity of the gonads  May result in diminished sex hormone biosynthesis and impaired gamete production and/or regulation  Causes infertility

 The way in which testosterone deficiency is treated depends on whether the treatment aims to improve fertility, sexual functioning, or both.  Gonadotrophin therapy – that is, treatment with hormones which stimulate the reproductive organs – has been shown to be effective in improving fertility in cases of secondary hypogonadism.
