Effect of Vitamin D Supplementation on Testosterone Levels in Men

Abstract: The male reproductive tract has been identified as a target tissue for vitamin D, and previous data suggest an association of 25-hydroxyvitamin D [25(OH)D] with testosterone levels in men. We therefore aimed to evaluate whether vitamin D supplementation influences testosterone levels in men. Healthy overweight men undergoing a weight reduction program who participated in a randomized controlled trial were analyzed for testosterone levels. The entire study included 200 nondiabetic subjects, of whom 165 particip… Show more

“…A recent study of men referred for coronary angiography noted that vitamin D levels had a positive association with testosterone levels [22]. Notably, in a placebo-controlled trial among overweight, otherwise healthy men, vitamin D replacement over a period of 1 year significantly increased testosterone levels [23]. In patients with cancer, chronic use of opioid analgesics can result in low testosterone [24], and in combination with low vitamin D levels this could predispose patients to loss of muscle mass and increase the insulin resistance associated with cancer cachexia [25] or obesity.…”

“…[28] Amazingly, the reverse situation is also true, suggesting that VD supplementation might increase T levels. [39] Although such a possible association between serum VD and T has been reported, still conflicting findings still exist. [40] In addition to clinical studies, patients with hypogonadism often have low VD levels due to the hydroxylating enzyme CY-P2R1 impairment in the testis.…”

“…В России недостаточность витамина D обнаружена у 78-83% населения [1,2]. Результаты по-следних эпидемиологических исследова-ний свидетельствуют о высокой частоте дефицита (недостаточности) витамина D у больных мужчин уроандрологического-профиля [3][4][5][6][7][8]. S. Pitman et al в 2011 году показали, что из 3763 исследуемых паци-ентов мужчин, у 68% имелся сниженный уровень витамина D [9].…”

“…Тюзикова, приблизительно у 50% россий-ских мужчин имеет место недиагностиро-ванная недостаточность витамина D, а у каждого третьего -тяжелый дефицит данного витамина [10]. При этом, наибо-лее часто дефицит витамина D у мужчин выявляется при ожирении, дефиците анд-рогенов, бесплодии и заболеваниях пред-стательной железы [3][4][5][6][7][8][9][10]. Получены убе-дительные доказательства, что дефицит витамина D у мужчин достоверно ассо-циируется с гипогонадизмом, ожирением, инсулинорезистентностью и сахарным диабетом 2 типа [11].…”
