The relationship between obesity and hypogonadism is complicated. The relationship is bidirectional and there are numerous causative and correlative factors on both sides of the equation. Obesity is increasing in prevalence in epidemic proportions. Likewise, we are beginning to see the rapid increase in the incidence of male hypogonadism.

Accumulating evidence suggests that varicocele, long associated with male infertility, is also a risk factor for low testosterone levels. The exact pathophysiology of the negative effects of varicocele on testicular function is not well understood, but theories include venous stasis, increased testicular temperature, oxidative stress, and resulting ...

Mixed hypogonadism: a neglected combined form of hypogonadism
Endocrine, 2023Kallmann syndrome is a rare disease characterized by delayed puberty, infertility and anosmia. We report the clinical and genetic characteristics of three patients with Kallmann syndrome who presented with Klinefelter syndrome and defined this neglected combined form of hypogonadism as mixed hypogonadism.Clinical data and examinations were obtained ...

This article outlines the changing pattern of gonadotropin-releasing hormone (GnRH)-induced gonadotropin secretion across sexual development, a knowledge of which is critical to understanding GnRH secretion in pathologic states such as hypogonadotropic hypogonadism.

Hypogonadism is a common finding in men, involving up to 5% of the population. Diagnosis of hypogonadism is dependent on clinical examination. Laboratory studies will confirm the cause. Treatment of testosterone deficiency is readily achieved; however, correction of spermatogenesis depends on the cause of the testicular failure.

Hypergonadotropic hypogonadism
American Journal of Obstetrics and Gynecology, 1983Etiologic factors in hypergonadotropic hypogonadism are discussed. On the basis of these data a classification system is proposed for women with hypergonadotropic hypogonadism to be used in future investigations of the natural history of this disorder.

Hypogonadotropic hypogonadism is characterized by failure of gonadal function secondary to deficient gonadotropin secretion, resulting from either a pituitary or hypothalamic defect, and is commonly seen in association with structural lesions or functional defects affecting this region.

Gonadotropin-releasing hormone (GnRH) and olfactory neurons migrate together from the olfactory placode, and GnRH neurons eventually reside in the hypothalamus. Hypogonadism in male infants may be diagnosed in the first 6 months of life but cannot be diagnosed during childhood until puberty occurs.

Delayed puberty is defined as absent testicular enlargement in boys or breast development in girls at an age that is 2 to 2.5 SDS later than the mean age at which these events occur in the population (traditionally, 14 years in boys and 13 years in girls).
