Evidence of male hypogonadism at an early age as a familial risk of type 2 diabetes.
    Annales d'endocrinologie, 2015, Volume: 76, Issue:6

    Previous investigations provide evidence of an association of hypogonadism with type 2 diabetes in men, and low testosterone levels have been regarded a risk factor for the disease. Since a strong genetic predisposition to type 2 diabetes has been demonstrated, here we investigate a possible tendency towards hypogonadism in young male offspring of diabetic parents.. The study compares 32 male offspring of diabetic parents with 31 male offspring of nondiabetic parents matched by age. The subjects comprised boys (9-17 years) and young adults (19-25 years). Anthropomorphic measurements were made in all subjects. Fasting blood samples were analyzed for glucose and serum concentrations of testosterone (T), sex hormone-binding globulin (SHBG), luteinizing hormone (LH), insulin and leptin were measured by ELISA. Free testosterone (FT) was calculated using T and SHBG levels.. Serum T, FT and bioavailable T (BAT) levels in offspring of diabetic parents were significantly lower than those of offspring of nondiabetic parents across all age groups. Mean serum LH levels were also lower in offspring of diabetic parents compared to the controls. Although LH levels in young adults with diabetic parents, tended to be lower than those of age-matched controls but the difference was not statistically significant. Serum insulin and leptin, and insulin resistance measured by HOMA-IR were significantly raised in older offspring of diabetic parents but were within the normal range.. Whereas hypogonadism was the only indicator of a possible predisposition to metabolic dysfunction in peripubertal children of diabetic parents, a significant change in other metabolic markers becomes apparent at a more advanced age.

The impact of obesity on the male reproductive axis.
    Journal of medicine and life, 2014, Jun-15, Volume: 7, Issue:2

    Obesity, defined as a body mass index (BMI) >30 kg/m2, has seen an important increase in prevalence in the last decades, not only in Europe and the United States, but also in developing countries. It is an established risk factor for numerous pathologic conditions like diabetes mellitus, cardiovascular diseases and cancer, but has also been linked to male hypogonadism. Several studies showed a negative impact of excessive BMI on testosterone levels, sexual function and sperm parameters. Possible mechanisms beyond this phenomenon are reduced hypothalamic and pituitary secretory function, excess estrogen production and reduced circulating sex-hormone binding globulin (SHBG). Peptides produced by the adipocyte may also trigger modifications of the reproductive function. Independently of the method used, non-surgical approach or bariatric techniques, weight reduction and a return to a normal BMI have been associated with improvement in the sexual function and levels of sexual hormones in obese males, showing that obesity related hypogonadism is preventable. Sexual and reproductive health might represent additional motivational factors for men in order to maintain a healthy life-style.
