Before I tackle the relationship between vitamin D and testosterone, I need to address several basics, which will clarify the bond between this. Horm Metab Res.

Nov 1;(11) doi: /jc Vitamin D and Testosterone in Healthy Men: A Randomized Controlled.

Physical activity Resistance training can raise testosterone levels for 15—30 minutes post-exercise. Prolonged endurance exercise especially can cause your testosterone to drop. Weight management Weight gain and the associated chronic diseases, such as cardiovascular disease and type 2 diabetes, [18] [19] [20] are strongly linked to decreases in testosterone, particularly in middle-aged and older men. If you gain weight as fatyour testosterone production drops.

Fortunately, if you lose weight, your testosterone production can climb back up.

J Clin Endocrinol Metab. A meta-analysis of 24 RCTs looked at weight loss caused by diet or bariatric surgery: You need not lose huge amounts of weight to see a bump in testosterone levels, either: If you lack sleep, you find it harder to exercise and easier to gain fat.

If you exercise, you find it easier to sleep and to keep a healthy weight. If your weight is healthy, you find it easier to exercise and easier to sleep.

Two caveats should be kept in mind, however: Supplementing with a vitamin or mineral is likely to help you only if you suffer from a deficiency or an insufficiency in this vitamin or mineral.

Correcting a deficiency or an insufficiency is more likely to raise your testosterone levels if they are low. Vitamin D Vitamin D helps regulate testosterone levels.

A total of people participated in this investigation. Among them, there were men who did not receive vitamin D and testosterone supplementation. Finally, this study included a total number of men with a mean SD age of 53 13 years.

Measurements In every site, the same trained staff group completed the questionnaire including information on demographic characteristics, medical history and lifestyle risk factors, and they collected anthropometric data. Body weight, height, and blood pressure were measured using standard methods, as previously described [ 12 ].

Does vitamin D affect testosterone levels?

Body mass index BMI was calculated as weight in kilograms divided by height in meters squared. The minimal detectable limit for hormones was as follows: The inter-assay coefficients of variation were as follows: The intra-assay coefficients of variation were as follows: We considered the residence area as a covariate because in China the prevalence of hypogonadism in rural and urban areas may be different [ 15 ].

The economic development status was measured by the average gross domestic product per capita of the entire nation US dollars, from the World Bank in as the cutoff point for each site. All of the analyses were two-sided. All reported P values were 2-sided. The general characteristics are summarized as the mean SD values for continuous variables or as a number with proportion for categorical variables. Model 1 was unadjusted. Model 2 was adjusted for age, residence area, economic development and current smoker.

The 25 OH D was divided into quartiles, with the first quartile representing the lowest one and the fourth quartile representing the highest. Model 1 was adjusted for age, residence area, economic status and current smoker. Model 3 included terms for model 2, diabetes and systolic pressure. Seven hundred thirteen Among these characteristics, men were diagnosed with hypogonadism by total T, men were diagnosed by free T and men were diagnosed by both total and free T.

Compared to men without hypogonadism, the men with hypogonadism were older and had significantly lower 25 OH D levels, higher fasting insulin levels, HOMA-IR, BMI and systolic pressure as well as a higher prevalence of diabetes.
