Long, Intense Exercise Linked To Lower Libido In Men

(Reuters Health) ― Men who routinely do unusually intense or long workouts may be less likely to have a normal libido than their peers who don’t work out so hard, a recent study suggests.Even though being overweight and sedentary has long been tied to low sex drive, or libido, some previous research has also linked endurance workouts like marathon training or long distance cycling to reduced levels of the male sex hormone testosterone and lower libido.For the current study, researchers examined survey data on exercise habits and libido for 1,077 healthy men. Compared to men with the most intense exercise regimens, men with the lowest intensity workouts were almost 7 times more likely to have a normal or high libido, the study found.Similarly, men who spent the least time on exercise were about four times more likely to have a high or normal libido as men who devoted the most time to training.”Our study is the first to examine the influence of large volumes of exercise training over a period of years,” said lead study author Dr. Anthony Hackney, a researcher in exercise physiology and nutrition at the University of North Carolina, Chapel Hill.The study isn’t a controlled experiment designed to prove that intense exercise lowers libido or why this might occur. But low testosterone after years of hard-core training is a likely culprit, Hackney said by email.”Our goal and research question was not to examine how to boost men’s libido, but to ...

igi L Abstract It is universally accepted that lifestyle interventions are the first step towards a good overall, reproductive and sexual health. Cessation of unhealthy habits, such as tobacco, alcohol and drug use, poor nutrition and sedentary behavior, is suggested in order to preserve/improve fertility in humans. However, the possible risks of physical exercise per se or sports on male fertility are less known. Being "fit" does not only improve the sense of well-being, but also has beneficial effects on general health: in fact physical exercise is by all means a low-cost, high-efficacy method for prev...

Publication date: Available online 15 August 2018Source: SteroidsAuthor(s): Julius Fink, Masahito Matsumoto, Yoshifumi TamuraAbstractSedentary lifestyle and over-nutrition are the main causes of obesity and type 2 diabetes (T2D). However, the same causes are major triggers of hypogonadism. Many T2D patients show low testosterone levels while hypogonadal men seem to be prone to become diabetic. Testosterone plays a major role in the regulation of muscle mass, adipose tissue, inflammation and insulin sensitivity and is therefore indirectly regulating several metabolic pathways, while T2D is commonly triggered by insulin resi...

Grzybowski, Joseph A. Lenkey, Anthony W. Moseman, Alec D. Bertsch, Nhien Dao, Heidi E. WalshAbstractObesity is a risk factor for infertility, but mechanisms underlying this risk are unclear. Fertility is regulated by hypothalamic gonadotropin-releasing hormone, encoded by the Gnrh1 gene. Because obesity promotes endoplasmic reticulum (ER) stress, we sought to determine how tunicamycin-induced ER stress affected Gnrh1 gene expression in the mo...

Male infertility has multiple etiologies, many of which are treatable. Recent reports have demonstrated the deleterious impact of obesity on male fertility. Obese men often experience hypogonadism, typically secondary to hyperestrogenemia. This is presumably due to increased aromatase activity in body fat, resulting in impaired hormone and sperm production. The aim of this study is to investigate the effect of anastrazole on semen profiles in infertile men with hyperestrogenemia.

Men and women follow the Wheat Belly lifestyle and can undergo important and sometime startling hormonal changes. Though results vary with stage of life—young adults, middle-aged, older—there are a variety of hormonal changes that women and men typically experience, some in concert, others independently. Such hormonal shifts can be powerful and part of the health-restoring menu of changes that develop with this lifestyle. They can even improve a relationship in a number of ways, both physically and emotionally, especially if we weave in some of the newer Wheat Belly/Undoctored concepts and practices such as oxy...

Abstract Congenital Leptin receptor (LEPR) deficiency is a rare genetic cause of early-onset morbid obesity characterised by severe early onset obesity, major hyperphagia, hypogonadotropic hypogonadism and immune and neuroendocrine/metabolic dysfunction. We identified a homozygous loss-of-function mutation, NM_002303.5:c.464 T > G; p.(Tyr155*), in the LEPR in an extended consanguineous family with multiple individuals affected by early-onset severe obesity and hyperphagia. Interestingly, the LEPR-deficient adult females have extremely high body mass index (BMI) with hypogonadal infertility, the B...

Summary In a case‐controlled study, we assessed the expressed seminal NAD‐dependent protein deacetylase (SIRT1) expression in infertile oligoasthenoteratozoospermic (OAT) men associated with varicocoele. Our study involved 81 men, recruited from the University hospitals, after ethical approval and informed consent. They were allocated into fertile normozoospermic men (n = 23), infertile OAT men without varicocoele (n = 23) and infertile OAT men with varicocoele (n = 35). Inclusion criteria consisted of confirmation of abnormal semen parameters and normal female partners whereas exclusion c...

CONCLUSION: MetS shows an important association with common male urogenital disorders such as benign prostatic enlargement, lower urinary tract symptoms, erectile dysfunction, infertility and renal disease. MetS affects male urogenital system mainly through endocrine and vascular mechanisms. Obesity, hypogonadism, obesity-induced androgen deficiency, hyperinsulinemia and inflammation are the mechanisms commonly involved and may act as potential targets for MetS-male urogenital system interrelations. Future studies are needed to evaluate the therapeutic approaches for intervention in MetS-male urogenital disease relations. ...

Conclusions: Concentrations of MnBP, MBzP and MEHP similar to those found in the urine of pregnant women consistently altered hCG and PPARγ expression in primary placental cells. These findings provide evidence for the molecular basis by which phthalates may alter placental function, and they provide a preliminary mechanistic hypothesis for opposite responses by sex. https://doi.org/10.1289/EHP1539 Received: 23 December 2016 Revised: 6 September 2017 Accepted: 18 September 2017 Published: 31 October 2017 Address correspondence to J.J.
