Examples of hypogonadism that affect hormone production more than fertility are hypopituitarism and Kallmann syndrome; in both cases, fertility is reduced until hormones are replaced but can be achieved solely with hormone replacement. Examples of hypogonadism that affect fertility more than hormone production are Klinefelter syndrome and ...
Androgen deficiency is a medical condition characterized by insufficient androgenic activity in the body. Androgen deficiency most commonly affects women, and is also called Female androgen insufficiency syndrome (FAIS), although it can happen in both sexes.
Hypergonadotropic hypogonadism (HH), also known as primary or peripheral/gonadal hypogonadism or primary gonadal failure, is a condition which is characterized by hypogonadism which is due to an impaired response of the gonads to the gonadotropins, follicle-stimulating hormone (FSH) and luteinizing hormone (LH), and in turn a lack of sex steroid production.

Testosterone is the primary male sex hormone and androgen in males. [3] In humans, testosterone plays a key role in the development of male reproductive tissues such as testicles and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair.
Diagnosis involves blood tests to measure growth hormone levels. [2] Treatment is by growth hormone replacement using synthetic human growth hormone. [1] The frequency of the condition is unclear. [2] Most cases are initially noticed in children. [1] The genetic forms of this disease are estimated to affect about 1 in 7,000 people. [3]
While 2.2% of young adult males report using steroids, 36.3% report using protein powders and shakes, while 10.1% said they use other muscle-building substances such as creatine and growth ...
Men reporting no sexual interest increased from 27.6% to 63.6% after orchiectomy, and from 31.7% to 58.0% after GnRH-A; men who experienced no erections increased from 35.0% to 78.6%; and men who did not report engaging in sexual activity increased from 47.9% to 82.8% after orchiectomy and 45.0% to 80.2%.

During puberty, hormones which stimulate androgen production result in the development of secondary sexual characteristics that result in even more differences between the sexes. These include greater muscle mass, greater height, the growth of facial hair and a lower body fat composition.
